Effect of Cannabis sativa extracts and cannabidiol on cell growth of cervical . Caspase 3/7 activity after treatment of SiHa, HeLa, and ME The aim of this study was to evaluate for the anti-growth effects of Cannabis sativa extracts and its isolate, cannabidiol on cervical cancer cell lines HeLa, SiHa, and ME Cannabis sativa extracts led to the up-regulation of apoptosis an increase in Caspase 3/7 and a decrease in the ATP levels.

Statistical analysis of the graphical data was expressed as the mean standard deviation. Camptothecin, as our positive control, significantly reduced cell viability in SiHa As shown in Fig. Whereas ethanol exhibited between 7. Representative cell viability bar graphs of cervical cancer cell lines. The IC 50 obtained during MTT assay was tested for their ability to alter cell viability in real time.
Cells were seeded in an E-plate and allowed to attach. Continuous changes in the impedance were measured and displayed as cell index CI. Little can be read from xCELLigence except that cannabidiol in all cell lines has shown to reduce cell index while the plant extract had mixed results sometimes showing reduction on the other hand remained unchanged Fig. Suggesting that cannabidiol is the most effective compound.
BXfluorescence confocal microscopy was used to visualize the cells. Apoptosis assessment following treatment of cervical cancer cells with IC 50 concentrations of Cannabis sativa extract and cannabidiol. These bar graphs are a representative of apoptosis induction in SiHa a and d , HeLa b and e , and ME c and f cells. Flow cytometry revealed a significant increase in SiHa cells undergoing apoptosis during treatment with butanol from 2 to In HeLa cells, apoptosis was increased to A similar events was observed following treatment of ME cells with butanol extract were Cannabidiol was also tested for its ability to induce apoptosis in all three cell lines.
The results further confirmed that the type of cell death induced was apoptosis. Figure shows that cannabidiol induced early apoptosis in all three cell lines. Cannabidiol was more effective in inducing apoptosis In comparison to both extracts of Cannabis sativa.
In SiHa cells cannabidiol induced To characterise the cell death type following treatment with our test compounds, cell were stained with DAPI and Annixin V to show if apoptosis was taking place. Treatment of SiHa and HeLa cells with IC 50 of both butanol and hexane extracts confirmed the type of cell death as apoptosis since they picked a green colour from Annexin V that bind on phosphotidyl molecules that appear in early stages of apoptosis.
Similar results were also observed in cannabidiol treated cells. Another feature that is a representative of cell death is the change in morphology.
Morphological appearance of live cells displayed a round blue nuclei following staining with DAPI. Loss of shape, nuclear fragmentation, reduction in cell size and blebbing of the cell membrane were among the observed morphological features implicated to be associated with apoptosis Fig.
Bar graphs representing changes in the ATP levels following treatment of cervical cancer cells with Cannabis sativa and cannabidiol. Untreated and camptothecin were included as controls for comparative purposes.
This was done in order to determine whether Cannabis sativa and cannabidiol deplete ATP levels in cervical cancer cells. In general, ATP depletion was cell type dependent. Whereas in ME there was no change between treatments and untreated. Similar results were observed in cannabidiol treated cells.
This could mean that cannabidiol depletes ATP levels more than Cannabis sativa extracts and might be the main compound responsible for cell death in cancer cells treated with Cannabis sativa. There was no significant change in ME cells Figure. ME was fairly increased also to from RLU all increase were significant and in line with other increase in apoptosis as shown in Annexin V. Representative bar graph of the cervical cancer cell cycle before and after treatment with Cannabis sativa extracts and cannabidiol.
Cells were harvested and treated with camptothecin and the IC 50 concentrations of Cannabis sativa extracts and cannabidiol. We further assessed the effects of Cannabis sativa extracts and cannabidiol on cell cycle progression using flow cytometry. In butanol, sub-G 0 phase was increased from 4.
In ME there was insignificant increase in all cell cycle stages. Each cell line responded differently to cannabidiol treatment. A similar trend was observed in HeLa cells but much lower sub-G 0 from 5. A similar event was observed during treatment of ME cells. Cannabidiol significantly increased sub-G0 in ME cells to From this data, we can conclude that cannabidiol induced cell death without cell cycle arrest. A densitometry analysis SiHa protein was performed using ImageJ quantification software to measure the relative band intensity.
The genes analyzed are p53 and RBBP6 including caspases. Equal amount of protein conc was loaded in each well. Note that the darker the bands increased expression of the gene. A densitometry analysis HeLa protein was performed using ImageJ quantification software to measure the relative band intensity.
A densitometry analysis ME protein was performed using ImageJ quantification software to measure the relative band intensity. Untreated protein was used as a control. Antibodies against pro-apoptotic proteins p53 and Bax and anti-apoptotic proteins Bcl-2 and RBBP6 , Initiator caspase-9 and effecter caspase-3 were included to elucidate apoptosis induction. From the apoptosis experiments conducted, it is clear that the mode of cell death induced by cannabidiol and extract of Cannabis Savita was that of apoptosis.
However, we needed to confirm whether the type of apoptosis induced is it p53 dependent or independent as it is well known that p53 is mutated in many cancers. Similar results were observed in hexane treated cells. In all cell lines the level of p53 negative regulator in cancer development was reduced by all treatment. Following treatment of cervical cancer cells, Bax protein was up-modulated and Bcl-2 was down-modulated.
Western blot analysis revealed that cannabidiol effectively caused an increase in the expression of pro-apoptosis proteins, p53 and Bax, while simultaneously decreasing the anti-apoptosis proteins, RBBP6 and Bcl-2 in all three cervical cancer cell lines SiHa, HeLa, and ME cells.
Caspases play an effective role in the execution of apoptosis, an effector caspase-9 and executor capsase-3 were included in our western blot to check if they played a role in inducing apoptosis. In all Cannabis sativa extracts, caspase-3 and caspase-9 were upregulated in all cell lines. Similar results were also observed in cannabidiol treated cells with upregulation of both caspase-3 and Cervical cancer remains a burden for women of Sub-Saharan Africa.
Half a million new cases of cervical cancer and a quarter of a million deaths are reported annually due to lack of effective treatment [ 12 ]. Currently, the recommended therapeutic regimens include chemotherapy, radiation therapy, and surgery.
However, they present several limitations including side effects or ineffectiveness [ 2 ]. Therefore, it is important to search for new novel therapeutic agents that are naturally synthesized and cheaper, but still remain effective. Medicinal plants have been used for decades for health benefits and to treat several different diseases [ 22 ]. However, some of the medicinal plants used by these individuals are not known to be effective and their safety is still unclear.
It is therefore important to scientifically evaluate and validate their efficacy and safety. In the present study, cervical cancer cell lines SiHa, HeLa, and ME were exposed to different concentrations of Cannabis sativa extracts and that of its compound, cannabidiol, with the aim of investigating their anti-proliferative activity.
We first determined whether Cannabis sativa extracts and cannabidiol possess anti-proliferative effects using MTT assay. These results correlate with the findings obtained by [ 23 ], whereby they reported reduced cell proliferation in colorectal cancer cell lines following treatment with Cannabis sativa.
It was suggested that cannabidiol might be responsible for the reported activities. Therefore, in this study, cannabidiol was included as a reference standard in order to determine whether the reported pharmacological activities displayed by Cannabis sativa extracts might have been due to the presence of this compound. For positive extract inhibitory activity, Camptothecin was included as a positive control.
Camptothecin functions as an inhibitor of a topoisomerase I enzyme that regulates winding of DNA strands [ 19 , 20 ]. This in turn causes DNA strands to break in the S-phase of the cell cycle [ 20 ]. A study conducted by [ 19 ], exhibited the ability of camptothecin to be cytotoxic against MCF-7 breast cancer cell line and also induce apoptosis as a mode of cell death at 0.
We also observed a similar cytotoxic pattern, whereby camptothecin induced cell death in HeLa, SiHa, and ME cells, however, at a much higher concentration. Upon treatment of SiHa and HeLa cells with IC 50 of butanol extract, we noted that there was little to no inhibitory effect observed on cell growth.
The growth curve continued in its exponential growth in all cells including the treated, untreated and 0. Differences in the findings could be attributable to the fact that both methods have different principles and mechanism of action.
MTT assay is an end-point method that is based on the reduction of tetrazolium salt into formazan crystals by mitochondrial succinate dehydrogenase enzyme. Mitochondrial succinate dehydrogenase is only active in live cells with an intact metabolism [ 8 , 13 ]. Induction of cell death by Cannabis sativa crude extracts decreases the activity of the enzyme following treatment of HeLa, SiHa, and ME cervical cancer cell lines.
On the other hand, xCELLigence system is a continuous method that relies on the use of E-plates engraved with gold microelectrodes at the bottom of the plate.
The xCELLigence system is based on the changes in impedance influenced by cell number, size and attachment [ 13 ]. Therefore, we concluded that it was possible that dead cells might have been attached at the bottom of the E-plate after treatment. Cell death can be characterized by a decrease in the energy levels as a result of dysfunction of the mitochondria [ 8 ].
Therefore, to evaluate the effect of treatment on the energy content of the cells, we conducted mitochondrial assay. ATP acts as determinant of both cell death and cell proliferation [ 15 ].
Treatment of cells with cannabidiol either slightly or severely depleted the ATP levels. According to [ 16 ], a reduction of the ATP levels compromises the status of cell and often leads to cell death either by apoptosis or necrosis, while an increase is indicative of cell proliferation. Therefore, we concluded that the reduction of ATP might have been as a result of cell death induction since the cells ATP production recovered.
Following confirmation that Cannabis sativa and cannabidiol have anti-proliferative activity, we had to verify whether both treatments have the ability to induce cell cycle arrest in all three cell lines. This method uses a PI stain and flow cytometry to measure the relative amount of DNA present in the cells. In this study, propidium iodide PI was used to stain cells. Propidium iodide can only intercalate into the DNA of fixed and permeabilized cells with a compromised plasma membrane or cells in the late stage of apoptosis.
Viable cells with an intact plasma membrane cannot uptake the dye. The intensity of stained cells correlates with the amount of DNA within the cells. Treatment of SiHa cells with butanol and hexane extracts led to the accumulation of cells in the cell death phase sub-G 0 phase , without cell cycle arrest.
And thus, according to [ 3 ], signals DNA synthesis and cell cycle proliferation. Interesting to note was that, treatment of ME cells with both extracts led to an increase of cells coupled by an increase in the S-phase population which favours replication and duplication of DNA. This was not the case following treatment of cells with cannabidiol. Cannabidiol resulted in the accumulation of cells in the cell death phase of the cell cycle.
In summary, Cannabis sativa induces cell death with or without cell cycle arrest while cannabidiol induces cell death without cell cycle arrest. Apoptosis plays a major role in determining cell survival. Viable cells cannot uptake both dyes due to the presence of an intact cell membrane. Since treatment caused the accumulation of cells in the sub-G 0 phase, also known as the cell death phase, and the severe depletion of ATP levels by cannabidiol, we further conducted an apoptosis assay.
Treatment of all three cell lines with camptothecin, IC 50 of Cannabis sativa and cannabidiol exhibited the type of induced cell death as apoptosis. Apoptosis is characterized by morphological changes and biochemical features which include condensation of chromatin, convolution of nuclear and cellular outlines, nuclear fragmentation, formation of apoptotic blebs within the plasma membrane, cell shrinkage due to the leakage of organelles in the cytoplasm as well as the presence of green stained cells at either late or early apoptosis [ 5 , 17 , 28 ].
This also proves that during cell growth analysis, SiHa and HeLa cells were undergoing cell death while still attached to the surface of the flask. Apoptosis is known to occur via two pathways, the death receptor pathway and the mitochondrial pathway [ 30 ]. Cannabis sativa isolates including cannabidiol have been implicated in apoptosis induction via the death receptor pathway, by binding to Fas receptor or through an activated of Bax triggered by the synthesis of ceramide in the cells [ 4 ].
However, not much has been reported on the induction of apoptosis via activation of p53 by Cannabis sativa. Our focus in this study was also to identify downstream molecular effect of extracts. The chloroform fraction of ES is the most cytotoxic fraction against T47D cells without prolonging the cell lifecycle. Anticancer potential of Hericium erinaceus extracts against particular human cancer cell lines.

This study demonstrates that Siegesbeckia orientalis ethanol extract SOE significantly inhibited the proliferation of RL human endometrial cancer cells. Treatment with SOE increased protein expression of caspase-3, -8 and -9 dose-dependently, indicating that apoptosis was through the intrinsic and extrinsic apoptotic pathways. In total, 10 constituents of SOE were identified by Gas chromatography-mass analysis.
Caryophyllene oxide and caryophyllene are largely responsible for most cytotoxic activity of SOE against RL cells. Overall, this study suggests that SOE is a promising anticancer agent for treating endometrial cancer. Justicia gendarussa methanolic leaf extracts from five different locations in the Southern region of Peninsular Malaysia and two flavonoids, kaempferol and naringenin, were tested for cytotoxic activity.
Kaempferol and naringenin were two flavonoids detected in leaf extracts using gas chromatography-flame ionization detection GC-FID. The results indicated that highest concentrations of kaempferol and naringenin were detected in leaves extracted from Mersing with Positive correlations were observed between kaempferol and naringenin concentrations in all leaf extracts analysed with the Pearson method.
The extract of ginger Zingiber officinale Roscoe and its major pungent components, -shogaol and -gingerol, have been shown to have an anti-proliferative effect on several tumor cell lines. However, the anticancer activity of the ginger extract in pancreatic cancer is poorly understood. Here, we demonstrate that the ethanol- extracted materials of ginger suppressed cell cycle progression and consequently induced the death of human pancreatic cancer cell lines, including Panc-1 cells.
The underlying mechanism entailed autosis, a recently characterized form of cell death, but not apoptosis or necroptosis. The autophagy inhibitors 3-methyladenine and chloroquine partially prevented cell death. Morphologically, however, focal membrane rupture, nuclear shrinkage, focal swelling of the perinuclear space and electron dense mitochondria, which are unique morphological features of autosis, were observed. The extract enhanced reactive oxygen species ROS generation, and the antioxidant N-acetylcystein attenuated cell death.

Cytotoxic effects of Mangifera indica L. Waterlily Mango Mangifera indica L. Cytological studies on the breast cancer cells were also conducted, and phytochemical analyses of the extract were carried out to determine the likely bioactive compounds responsible for such effects. The extract showed significant toxicity towards both cell lines, with low toxicity to normal breast cells MCFA.
The cytotoxic effects on the cells were further confirmed by the NR uptake, antiproliferative and LDH release assays. Bioactive analyses revealed that many bioactives were present in the extract although butylated hydroxytoluene, a potent antioxidant, was the most abundant with Synergistic effects of its antioxidant bioactives could have contributed to the cytotoxic effects of the extract.

Huaier treatment inhibited cell viability in all three cell lines and induced various large membranous vacuoles in the cytoplasm. In addition, electron microscopy, MDC staining, accumulated expression of autophagy markers and flow cytometry revealed that Huaier extract triggered autophagy. Inhibition of autophagy attenuated Huaier-induced cell death. Cymbopogon citratus and Camellia sinensis extracts selectively induce apoptosis in cancer cells and reduce growth of lymphoma xenografts in vivo.
Cancer cells are reported to have elevated levels of reactive oxygen species ROS and are highly dependent on cellular defense mechanisms against oxidative stress. Numerous nutraceuticals and natural polyphenolic compounds have a wide range of abilities to alter cellular redox states with potential implications in various diseases.
Furthermore, therapeutic options for cancers are mostly nonselective treatments including genotoxic or tubulin-targeting compounds. Some of the natural extracts , containing multiple bioactive compounds, could target multiple pathways in cancer cells to selectively induce cell death. Cymbopogon citratus lemongrass and Camellia sinensis white tea extracts have been shown to have medicinal properties, however, their activity against lymphoma and leukemia, as well as mechanistic details, have not been fully characterized.
Herein, we report potent anti- cancer properties in dose and time-dependent manners of ethanolic lemongrass and hot water white tea extracts in lymphoma and leukemia models.
Both extracts were able to effectively induce apoptosis selectively in these human cancer cell types. Interestingly, ethanolic lemongrass extract induces apoptosis primarily by the extrinsic pathway and was found to be dependent on the generation of ROS.
Conversely, apoptotic induction by hot water white tea extract was independent of ROS. Furthermore, both of these extracts caused mitochondrial depolarization and decreased rates of oxygen consumption in lymphoma and leukemia cells , leading to cell death.
Most importantly, both these extracts were effective in reducing tumor growth in human lymphoma xenograft models when administered orally. Thus, these natural extracts could have potential for being nontoxic alternatives for the treatment of cancer. Green tea extract selectively targets nanomechanics of live metastatic cancer cells. Cancer 9 with various biological activities Lu et al Clin. The biomechanical response of GTE treated cells taken directly from patient's body samples was measured using atomic force microscopy AFM Binnig et al Phys.
We found significant increase in stiffness of GTE treated metastatic tumor cells , with a resulting value similar to untreated normal mesothelial cells , whereas mesothelial cell stiffness after GTE treatment is unchanged.
Immunofluorescence analysis showed an increase in cytoskeletal-F-actin in GTE treated tumor cells , suggesting GTE treated tumor cells display mechanical, structural and morphological features similar to normal cells , which appears to be mediated by annexin-I expression, as determined by siRNA analysis of an in vitro cell line model. Our data indicates that GTE selectively targets human metastatic cancer cells but not normal mesothelial cells , a finding that is significantly advantageous compared to conventional chemotherapy agents.
Pro-apoptotic and anti-proliferative effects of corn silk extract on human colon cancer cell lines. Corn silk is an economically and nutritionally significant natural product as it represents a staple food for a large proportion of the world population.

Thus, RLEs may be potentially useful as antimetastatic agents for oral cancer chemotherapy. Effects of different extracts of curcumin on TPC1 papillary thyroid cancer cell line.
The thyroid gland is one of the largest endocrine glands in the body. Curcumin possesses a wide variety of biological functions, and thanks to its properties, it has gained considerable attention due to its profound medicinal values Prasad, Gupta, Tyagi, and Aggarwal, Biotechnol Adv We have undertaken the present work in order to define the possible role of curcumin in modulating the genetic expression of cell markers and to understand the effectiveness of this nutraceutical in modulating the regression of cancer phenotype.
As a template we used the TPC-1 cells treated with the different extracts of turmeric, and examined the levels of expression of different markers proliferative, inflammatory, antioxidant, apoptotic.
Treatment with the three different curcumin extracts displays anti-inflammatory, antioxidant properties and it is able to influence cell cycle with slightly different effects upon the extracts. Furthermore curcumin is able to influence cell metabolic activity vitality. In conclusion curcumin has the potential to be developed as a safe therapeutic but further studies are needed to verify its antitumor ability in vivo. Our results revealed that corn silk extract inhibited the proliferation of cancer cells and increased the level of apoptosis in a concentration-dependent manner.
Western blot analysis revealed that corn silk extract upregulated the levels of Bax, cytochrome c , caspase-3 and caspase-9, but downregulated the levels of B- cell lymphoma 2. These results suggest that corn silk extract may induce apoptosis through the mitochondria-mediated pathway.
Full Text Available Type II endometrial carcinoma typically exhibits aggressive metastasis and results in a poor prognosis. Siegesbeckia orientalis Linne is a traditional Chinese medicinal herb with several medicinal benefits, including the cytotoxicity against various cancers. This study investigates the inhibitory effects of S. The inhibitory effects were evaluated by determining wound healing and performing the Boyden chamber assay.
The results of this investigation suggest that SOE is a potential anti-metastatic agent against human endometrial tumors. Green tea extract induces protective autophagy in A non-small lung cancer cell line. For many decades, polyphenols, including green tea extract catechins, have been reported to exert multiple anti-tumor activities.
However, to date the mechanisms of their action have not been completely elucidated. Thus, the aim of this study was to assess the effect of green tea extract on non-small lung cancer A cells. A cells following treatment with GTE were analyzed using the inverted light and fluorescence microscope. In order to evaluate cell sensitivity and cell death, the MTT assay and Tali image-based cytometer were used, respectively.
Ultrastructural alterations were assessed using a transmission electron microscope. Likewise, the treatment with GTE resulted in only a very small dose-dependent increase in the population of apoptotic cells. However, enhanced accumulation of vacuole-like structures in response to GTE was seen at the light and electron microscopic level.
Furthermore, an increase in the acidic vesicular organelles and LC3-II puncta formation was observed under the fluorescence microscope, following GTE treatment.
The analysis of the functional status of autophagy revealed that GTE-induced autophagy may provide self-protection against its own cytotoxicity, since we observed that the blockage of autophagy by bafilomycin A1 decreased the viability of A cells and potentiated necrotic cell death induction in response to GTE treatment.
Collectively, our results revealed that A cells are insensitive to both low and high concentrations of the green tea extract , probably due to the induction of cytoprotective autophagy. These data suggest that a potential utility of GTE in lung cancer therapy may lie in its synergistic combinations with drugs or small molecules that target autophagy, rather than in monotherapy. Full Text Available Background and objectives: Selective modulation of endoplasmic reticulum stress markers in prostate cancer cells by a standardized mangosteen fruit extract.
Full Text Available The increased proliferation of cancer cells is directly dependent on the increased activity of the endoplasmic reticulum ER machinery which is responsible for protein folding, assembly, and transport. In fact, it is so critical that perturbations in the endoplasmic reticulum can lead to apoptosis.
This carefully regulated organelle represents a unique target of cancer cells while sparing healthy cells. In this study, a standardized mangosteen fruit extract MFE was evaluated for modulating ER stress proteins in prostate cancer. Next, we evaluated MFE for microsomal stability and anti- cancer activity in nude mice.
MFE induced apoptosis, decreased viability and proliferation in prostate cancer cells. MFE increased the expression of ER stress proteins.
MFE suppressed tumor growth in a xenograft tumor model without obvious toxicity. Mangosteen fruit extract selectively promotes endoplasmic reticulum stress in cancer cells while sparing non-tumorigenic prostate epithelial cells. Furthermore, in an in vivo setting mangosteen fruit extract significantly reduces xenograft tumor formation.
The increased proliferation of cancer cells is directly dependent on the increased activity of the endoplasmic reticulum ER machinery which is responsible for protein folding, assembly, and transport. The extract from Punica granatum pomegranate peel induces apoptosis and impairs metastasis in prostate cancer cells. Prostate cancer is a big threat to male for its poor prognosis and high mortality rate.
Natural compounds are important resources of many anticancer drugs. Pomegranate is a kind of antioxidant-rich fruit and its peel and seed has potential anticancer activities. In this study, we aimed to investigate the effects of pomegranate peel extract PoPx on the apoptosis and metastasis of prostate cancer cells and the related mechanism. We found that PoPx showed growth inhibition on prostate cancer cells. Nuclei morphological and flow cytometer FCM analysis indicated that PoPx could induce prostate cancer apoptosis.
Further investigation indicated that mitochondrial mediated intrinsic pathway is involved in the apoptosis. Wound healing assay and transwell migration and invasion assay implied that PoPx has the potential to inhibit migration and invasion, two critical steps in prostate cancer metastasis. In summary, the present data showed that PoPx could be a promising drug candidate to treat prostate cancer , showing us a better way to develop novel drugs from natural compounds.
Due to the chemo resistant nature of cancer cells and adverse effects of current therapies, researchers are looking for the most efficient therapeutic approach which has the lowest side effects and the highest toxicity on cancer cells. The aim of the present study was to investigate the synergic effect of Urtica dioica extract in combination with paclitaxel on cell death and invasion of human breast cancer MDA-MB cell line.
To determine the cytotoxic effects of Urtica dioica extract with paclitaxel, MTT assay was performed. The scratch test was exploited to assess the effects of Urtica dioica, Paclitaxel alone and combination on migration of cancer cells. The effects of plant extract , Paclitaxel alone and combination on different phases of cell cycle was analyzed using flow cytometry.
Results of MTT assay showed that Urtica dioica significantly destroyed cancer cells. Interestingly, Concurrent use of Urtica dioica extract with paclitaxel resulted in decreased IC50 dose of paclitaxel.
Moreover, findings of scratch assay exhibited the inhibitory effects of Urtica dioica, Paclitaxel alone and combination on migration of MDA-MB cell line. Our findings also demonstrated that the extract substantially decreased the Snail-1 and related gene expression.
Our results demonstrated that the dichloromethane extract of Urtica dioica inhibit cell growth and migration. Also, Urtica dioica extract substantially increased sensitivity of breast cancer cells to paclitaxel. Therefore, it can be used as a potential candidate for treatment of breast cancer with paclitaxel.

Effects of Calophyllum inophyllum fruit extract on the proliferation and morphological characteristics of human breast cancer cells MCF Full Text Available Objective: To evaluate the antiproliferative activity of Calophyllum inophyllum C. The cytotoxic effect of C.
The preliminary time-based morphological investigation of MCF-7 cells treated with the IC 50 value This study clearly proved that the proliferation of human breast cancer cell MCF-7 was inhibited by C. Research on marine natural products as potential anticancer agents is still limited.
In the present study, an aqueous extract of a Canadian marine microalgal preparation was assessed for anticancer activities using various assays and cell lines of human cancers , including lung, prostate, stomach, breast, and pancreatic cancers , as well as an osteosarcoma.
In vitro, the microalgal extract exhibited marked anticolony forming activity. In addition, it was more toxic, as indicated by increased apoptosis, to nonadherent cells grown in suspension than to adherent cells. The results of the present study suggest that the antimetastatic effect of the aqueous microalgal extract is based on inhibition of colony forming ability of cancer cells and the preferential killing of suspended cancer cells.
Further research aimed at identification of the molecular basis of the anticancer activities of the microalgal extract appears to be warranted. Full Text Available Research on marine natural products as potential anticancer agents is still limited. Antiproliferative effects of the readily extractable fractions prepared from various citrus juices on several cancer cell lines.
Screening of 34 Citrus juices indicated that King Citrus nobilis strongly inhibited proliferation of all cancer cell lines examined. Sweet lime and Kabuchi inhibited three of the four cancer cell lines. In contrast, these samples were substantially less cytotoxic toward normal human cell lines. Supercritical carbon dioxide extract of Physalis peruviana induced cell cycle arrest and apoptosis in human lung cancer H cells.
PP is a popular folk medicine used for treating cancer , leukemia, hepatitis, rheumatism and other diseases. In this study, our objectives were to examine the total flavonoid and phenol content of different PP extracts aqueous: EEPP; supercritical carbon dioxide: Among all the extracts tested, results showed that SCEPP-5 possessed the highest total flavonoid SCEPP-5 not only induced cell cycle arrest at S phase, it also up-regulated the expression of pro-apoptotic protein Bax and down-regulated the inhibitor of apoptosis protein IAP.
Furthermore, the apoptotic induction in H cells was found to associate with an elevated p53 protein expression, cytochrome c release, caspase-3 activation and PARP cleavage. Taken together, these results conclude that SCEPP-5 induced cell cycle arrest at S phase, and its apoptotic induction could be mediated through the pdependent pathway and modification of Bax and XIAP proteins expression.
The results have also provided important pharmacological backgrounds for the potential use of PP supercritical fluid extract as products for cancer prevention.

Conium's effects on cell cycle, reacti Full Text Available Herbal medicines are often combinations of botanical extracts that are assumed to have additive or synergistic effects. The purpose of this investigation was to compare the effect of individual botanical extracts with combinations of extracts on prostate cell viability.
We then modeled the interactions between botanical extracts in combination isobolographically. Scutellaria baicalensis, Rabdosia rubescens, Panax-pseudo ginseng, Dendranthema morifolium, Glycyrrhiza uralensis and Serenoa repens were collected, taxonomically identified and extracts prepared.
Effects of the extracts on cell viability were quantitated in prostate cell lines using a luminescent ATP cell viability assay. Combinations of two botanical extracts of the four most active extracts were tested in the 22Rv1 cell line and their interactions assessed using isobolographic analysis. Each extract significantly inhibited the proliferation of prostate cell lines in a time- and dose-dependent manner except repens. The most active extracts , baicalensis, D.
The remaining two- extract combinations showed antagonism. The four extracts together were significantly more effective than the two-by-two combinations and the individual extracts alone. Combining the four herbal extracts significantly enhanced their activity in the cell lines tested compared with extracts alone.
The less predictable nature of the two-way combinations suggests a need for careful characterization of the effects of each individual herb based on their intended use. Scholtysek, Carina; Krukiewicz, Aleksandra A. An assumption is that SPBE affects tumor cell progression and migration in breast and prostate tissue.
In the presence of cholesterol, these features are not only reversed but increased significantly. Since the protein p53 is also regarded as nuclear matrix protein facilitating actin cytoskeletal binding, 2D tractions were measured.
The results suggest a dual function of p53 in cells. In this work, DU cells were used to demonstrate that SPBE and its sterol components, beta-sitosterol and stigmasterol, inhibit prostate cancer growth by increasing p53 protein expression and also inhibit carcinoma development by decreasing p21 and p27 protein expression. The results show for the first time the potential of SPBE, beta-sitosterol and stigmasterol as potential anti-tumor agents.
The cell adhesion strength in the presence of SPBE, beta-sitosterol and cholesterol and the observation was that the increase in p53 expression triggered an increase in the intracellular force generation. Anticancer activity of Kalanchoe tubiflora extract against human lung cancer cells in vitro and in vivo.
Uncontrolled cell proliferation is a common feature of human cancer. Some of herbal extract or plant-derived medicine had been shown as an important source of effective anticancer agents. We previously reported that an n-BuOH-soluble fraction of Kalanchoe tubiflora has antiproliferative activity by inducing mitotic catastrophe.
In this study, we showed that the H 2 O-soluble fraction of Kalanchoe tubiflora KT-W caused cell cycle arrest, and senescence-inducing activities in A cells. We used 2 dimensional PAGE to analyze the protein expression levels after KT-W treatment, and identified that the energy metabolism-related proteins and senescence-related proteins were disturbed. In vivo experiments showed that the tumor growths in Axenografted nude mice were effectively inhibited by KT-W.
Our findings implied that KT-W is a putative antitumor agent by inducing cell cycle arrest and senescence. Phytochemical properties and anti-proliferative activity of Olea europaea L.

Full Text Available Cancer related morbidity and mortality is a major health care concern.
Developing potent anti- cancer therapies which are non-toxic, sustainable and affordable is of alternative medicine. This study was designed to investigate the aqueous natural extracts mixture NE mix prepared from common spices turmeric, ginger and garlic for its free radical scavenging potential and anti- cancer property against human breast cancer cell lines MCF-7, ZR and MDA-MB To the best of our knowledge, NE mix with and without Tamoxifen has not been tested for its anti- cancer potential.
The extent of apoptosis due to combined treatment with NE mix-Tamoxifen was higher than Tamoxifen alone, indicating a potential role of the NE mix in sensitizing the ER-positive breast cancer cells towards Tamoxifen. Our data strongly indicate that our NE mixture is a potential alternative therapeutic approach in certain types of cancer. The ethanol extract of Scutellaria baicalensis and the active compounds induce cell cycle arrest and apoptosis including upregulation of p53 and Bax in human lung cancer cells.
Despite a lack of scientific authentication, Scutellaria baicalensis is clinically used in Chinese medicine as a traditional adjuvant to chemotherapy of lung cancer. In this study, cytotoxicity assays demonstrated that crude ethanolic extracts of S. The active compounds baicalin, baicalein and wogonin did not exhibit such selectivity. The altered protein expression indicated that cell growth arrest and apoptosis were potential mechanisms of cytotoxicity.
These observations were supported by PI staining cell cycle analysis using flow cytometry and Annexin-V apoptotic analysis by fluorescence microscopy of cancer cells treated with the crude extract and pure active compounds. Following treatment, increased expression in the cancer cells of key proteins related to the enhancement of apoptosis was observed for p53 and Bax. These results provide further insight into the molecular mechanisms underlying the clinical use of this herb as an adjuvant to lung cancer therapy.
