Abstract
Argemone mexicana(Pepaveraceae) is an important medicinal plant commonly known as 'maxican prickly poppy' and is traditionally used to treat skin diseases. In the present study, the extract/fractions of aerial parts of A. mexicana after carrying out the organoleptic characteristics were sequentially extracted with the solvents of increasing polarities. Total fractions were examined for their radical scavenging activities in DPPH and DNA nicking assays. Among all, maximum antioxidant activity was shown by chloroform fraction (AmC) in DPPH assay with IC50 of 26.12 μg/ml, and DNA nicking assay showed 80.91% protective potential. The AmC fraction was analyzed for its antibacterial, cytotoxic potential, cell cycle analysis, mitochondrial membrane potential (MMP) and accumulation of reactive oxygen species (ROS) using A431 cell line. The AmC fraction exhibited remarkable antibacterial activity against bacterial strains in the order Klebsiella pneumoniae> Bacillussubtilis> Salmonella typhi> Staphylococcus epidermidis. The cytotoxic potential of the AmC fraction was analyzed in skin epidermoid carcinoma (A431) cells, osteosarcoma (MG-63) and cervical (HeLa) cell lines with a GI50 value of 47.04 μg/ml, 91.46 μg/ml and 102.90 μg/ml, respectively. The AmC fraction was extended further to explore its role in cell death using A431 cell line. Phase contrast and scanning electron microscopic studies on A431 cells exhibited all the characteristics indicative of apoptosis, viz., viability loss, cell shrinkage, cell rounding-off, DNA fragmentation and formation of apoptotic bodies. Flow cytometric analysis revealed enhanced ROS level, decreased MMP and arrest cell cycle at the G0/G1 phase further strengthened cell death by apoptosis. Increased expressions of apoptotic markers (p53, PUMA, cyt c, Fas and Apaf-1) were confirmed by RT-qPCR analysis. Furthermore, the AmC fraction was subjected to ultra-high-performance liquid chromatography, which revealed the presence of different polyphenols in the order: caffeic acid> epicatechin> kaempferol> chlorogenic acid> gallic acid> catechin> ellagic acid >umbeliferone> quercetin> coumaric acid. A critical analysis of results revealed that the AmC fraction induced cell death in epidermoid carcinoma cells via ROS and p53-mediated apoptotic pathway which may be ascribed to the presence of polyphenols in it.

Cissus verticillata Extract Decreases Neuronal Damage Induced by Oxidative Stress in HT22 Cells and Ischemia in Gerbils by Reducing the Inflammation and Phosphorylation of MAPKs. PLANTS 2021; 10:plants10061217. [PMID: 34203930 PMCID: PMC8232592 DOI: 10.3390/plants10061217] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/22/2021] [Revised: 05/31/2021] [Accepted: 06/10/2021] [Indexed: 12/13/2022]
Abstract
In the present study, we examined the effects of Cissus verticillata leaf extracts (CVE) against hydrogen peroxide (H2O2)- and ischemia-induced neuronal damage in HT22 cells and gerbil hippocampus. Incubation with CVE produced concentration-dependent toxicity in HT22 cells. Significant cellular toxicity was observed with >75 μg/mL CVE. CVE treatment at 50 μg/mL ameliorated H2O2-induced reactive oxygen species formation, DNA fragmentation, and cell death in HT22 cells. In addition, incubation with CVE significantly mitigated the increase in Bax and decrease in Bcl-2 induced by H2O2 treatment in HT22 cells. In an in vivo study, the administration of CVE to gerbils significantly decreased ischemia-induced motor activity 1 d after ischemia, as well as neuronal death and microglial activation 4 d after ischemia, respectively. CVE treatment reduced the release of interleukin-1β, interleukin-6, and tumor necrosis factor-α 6 h after ischemia. Furthermore, CVE treatment significantly ameliorated ischemia-induced phosphorylation of c-Jun N-terminal kinase, extracellular signal-regulated kinase 1/2, and p38. These results suggest that CVE has the potential to reduce the neuronal damage induced by oxidative and ischemic stress by reducing the inflammatory responses and phosphorylation of MAPKs, suggesting that CVE could be a functional food to prevent neuronal damage induced by ischemia.

Protective Effects of a Lutein Ester Prodrug, Lutein Diglutaric Acid, against H 2O 2-Induced Oxidative Stress in Human Retinal Pigment Epithelial Cells. Int J Mol Sci 2021; 22:ijms22094722. [PMID: 33946898 PMCID: PMC8125252 DOI: 10.3390/ijms22094722] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2021] [Revised: 04/26/2021] [Accepted: 04/26/2021] [Indexed: 12/21/2022] Open
Abstract
Oxidative stress-induced cell damage and death of the retinal pigmented epithelium (RPE), a polarized monolayer that maintains retinal health and homeostasis, lead to the development of age-related macular degeneration (AMD). Several studies show that the naturally occurring antioxidant Lutein (Lut) can protect RPE cells from oxidative stress. However, the poor solubility and low oral bioavailability limit the potential of Lut as a therapeutic agent. In this study, lutein diglutaric acid (Lut-DG), a prodrug of Lut, was synthesized and its ability to protect human ARPE-19 cells from oxidative stress was tested compared to Lut. Both Lut and Lut-DG significantly decreased H2O2-induced reactive oxygen species (ROS) production and protected RPE cells from oxidative stress-induced death. Moreover, the immunoblotting analysis indicated that both drugs exerted their protective effects by modulating phosphorylated MAPKs (p38, ERK1/2 and SAPK/JNK) and downstream molecules Bax, Bcl-2 and Cytochrome c. In addition, the enzymatic antioxidants glutathione peroxidase (GPx) and catalase (CAT) and non-enzymatic antioxidant glutathione (GSH) were enhanced in cells treated with Lut and Lut-DG. In all cases, Lut-DG was more effective than its parent drug against oxidative stress-induced damage to RPE cells. These findings highlight Lut-DG as a more potent compound than Lut with the protective effects against oxidative stress in RPE cells through the modulation of key MAPKs, apoptotic and antioxidant molecular pathways.

Abstract
The bioassay-guided fractionation of a CHCl3-MeOH extract from the stems of Cissus trifoliata identified an active fraction against PC3 prostate cancer cells. The treatment for 24 h showed an 80% reduction in cell viability (p ≤ 0.05) by a WST-1 assay at a concentration of 100 μg/mL. The HPLC-QTOF-MS analysis of the fraction showed the presence of coumaric and isoferulic acids, apigenin, kaempferol, chrysoeriol, naringenin, ursolic and betulinic acids, hexadecadienoic and octadecadienoic fatty acids, and the stilbene resveratrol. The exposure of PC3 cells to resveratrol (IC25 = 23 μg/mL) for 24 h induced significant changes in 847 genes (Z-score ≥ ±2). The functional classification tool of the DAVID v6.8 platform indicates that the underlying molecular mechanisms against the proliferation of PC3 cells were associated (p ≤ 0.05) with the process of differentiation and metabolism. These findings provide experimental evidence suggesting the potential of C. trifoliata as a promising natural source of anticancer compounds.

Abstract
Zizyphus mauritiana Lam. seeds (ZMS) have been used medicinally as sedative or hypnotic drugs in most of Asian countries. ZMS has significant benefits to the human health. Therefore, we have evaluated immunomodulatory effect of lectin extracted from these ZMSL in both in vitro and in vivo study. Anaphylaxis is a severe life-threatening allergic reaction and Arthus reaction is deposition of immune complex and complement system activation, so we hypothesized that if ZMSL can protect these severe allergic diseases. We have studied the effect of ZMSL on macrophages and Wistar albino rats and confirmed its protective effect against anaphylaxis and Arthus reaction. Results of this study suggest ZMSL have immunostimulatory and antiallergic activity.

Abstract
BACKGROUND AND PURPOSE Leukemia is considered a top-listed ailment, according to WHO, which contributes to the death of a major population of the world every year. Paris Saponin VII (PS), a saponin which was isolated from the roots of Trillium kamtschaticum, from our group, was reported to provide hemostatic, cytotoxic and antimicrobial activities. However, its molecular mechanism underlying the anti-proliferative effects remains unclear. Thus, this study hypothesized to assess that mechanism in PS treated HEL cells. METHODS The MTT assay was used to analyze the PS inhibited cell viability in the HEL cells. We further found that PS could induce S phase cell cycle arrest through flow cytometry as well as the western blot analysis of intrinsic and extrinsic apoptotic molecules. RESULTS The MTT assay showed the IC50 concentration of PS as 0.667μM. The study revealed that PS treatment inhibits cell proliferation dose-dependently. It further caused mitochondrial membrane potential changes by PS treatment. Mechanistic protein expression revealed a dose-dependent upsurge for Bid and Bim molecules, while Bcl2 and PARP expression levels were significantly (P<0.05) down-regulated in PS treated HEL cells resulting in caspase -3 release and increased the Bim levels upon 24h of incubation. CONCLUSION These findings indicate that PS possesses an excellent anti-leukemic activity via the regulation of the mitochondrial pathway, leading to S phase cell cycle arrest and caspase-dependent apoptosis, suggesting it as a potential alternative chemotherapeutic agent for leukemia patients.

Abstract
The crude methanolic extract obtained from Verbascum nigrum aerial parts (VNE) and its six fractions (VNF1-VNF6) were initially screened regarding their effects on the viability of immortalized HaCaT keratinocytes and A431 epidermoid carcinoma cells (MTT assay, 24 h). None of the tested samples affected the viability of HaCaT cells in a concentration range of 25-150 μg/mL. VNE and VNF4 exhibited significant cytotoxic effects in A431 cells, with IC50 values of 81.92 and 12.27 μg/mL, respectively; the selectivity index was higher than 10 for VNF4. The untargeted LC/HR-MS/MS metabolite profiling led to the tentative annotation of a total number of 23 compounds. Of these, VNE comprised mainly iridoid glycosides (harpagoside, laterioside, acylated aucubin derivatives), whereas VNF4 showed a high abundance of triterpene saponin glycosides (ilwensisaponins A and C, songarosaponins A and B), constituents known for their selective cytotoxic potential.

Abstract
Mitochondria are the key energy provider to highly proliferating cancer cells, and are subsequently considered one of the critical targets in cancer therapeutics. Several compounds have been studied for their mitochondria-targeting ability in cancer cells. These studies’ outcomes have led to the invention of “mitocans”, a category of drug known to precisely target the cancer cells’ mitochondria. Based upon their mode of action, mitocans have been divided into eight classes. To date, different synthetic compounds have been suggested to be potential mitocans, but unfortunately, they are observed to exert adverse effects. Many studies have been published justifying the medicinal significance of large numbers of natural agents for their mitochondria-targeting ability and anticancer activities with minimal or no side effects. However, these natural agents have never been critically analyzed for their mitochondria-targeting activity. This review aims to evaluate the various natural agents affecting mitochondria and categorize them in different classes. Henceforth, our study may further support the potential mitocan behavior of various natural agents and highlight their significance in formulating novel potential anticancer therapeutics.

Abstract
Cissus trifoliata (L.) L belongs to the Vitaceae family and is an important medicinal plant used in Mexico for the management of infectious diseases and tumors. The present study aimed to evaluate the metabolic profile of the stems of C. trifoliata and to correlate the results with their antibacterial and cytotoxic activities. The hexane extract was analyzed using gas chromatography coupled with mass spectrometry (GC-MS) and the CHCl3-MeOH and aqueous extracts by ultraperformance liquid chromatography quadrupole time of fly mass spectrometry (UPLC-QTOF-MS). The antibacterial activity was determined by broth microdilution and the cytotoxicity was evaluated using MTS cell proliferation assay. Forty-six metabolites were putatively identified from the three extracts. Overall, terpenes, flavonoids and stilbenes characterize the metabolic profile. No antibacterial activity was found in any extract against the fifteen bacteria strains tested (MIC >500 µg/mL). However, high cytotoxic activity (IC50 ≤ 30 µg/mL) was found in the hexane and aqueous extracts against hepatocarcinoma and breast cancer cells (Hep3B, HepG2 and MCF7). This is the first report of the bioactive compounds of C. trifoliata stems and their antibacterial and cytotoxic properties. The metabolic profile rich in anticancer compounds correlate with the cytotoxic activity of the extracts from the stems of C. trifoliata. This study shows the antitumor effects of this plant used in the traditional medicine and justifies further research of its anticancer activity.

Abstract
The objective of this study was to understand the changes of nutrition constituents in extracts of four varieties of barley fermented with Lactobacillus plantarum dy-1 (LFBEs) and to uncover the potential apoptosis-related mechanism induced by LFBE to inhibit the proliferation of HT-29 cells. The contents of total polysaccharide, polyphenol, and protein in the four LFBEs significantly changed as the fermentation time went by and exerted different inhibitory effects on the proliferation of HT-29 cells. Results indicated that LFBE (YangSi No.3) inhibited proliferation of HT-29 cells in a time- and dose-dependent manners. The scanning electron micrograph illustrated that LFBE caused representative apoptotic trait and flow cytometric analysis suggested that LFBE brought about apoptosis by ceasing cell cycle at S phase. Western-blotting results indicated that LFBE promoted apoptosis was relevant to the regulation of apoptosis-related proteins, such as B-cell lymphoma-2 (Bcl-2), Bcl-2-associated X protein (Bax), and the release of Cytochrome-C from mitochondria. PRACTICAL APPLICATIONS: Abundant studies have reported that extracts of fermented barley held the activities of anti-obesity, antitumor, and so on. However, little information about the comparison in the chemical profile and antiproliferation property among different barley varieties (namely, YangSi barley No.1, YangSi barley No.3, DaZhong 88-91, XiYin No.2) was observed. Results indicated that LFBE (YangSi No.3 barley) exhibited the best inhibitory property by inducing the apoptosis of HT-29 cells. These findings may be beneficial to select a higher nutritional value barley and optimize the fermentation conditions to maximize the bioactive concentration expected in foods for the human.

Protective Effects of Curcumin Ester Prodrug, Curcumin Diethyl Disuccinate against H 2O 2-Induced Oxidative Stress in Human Retinal Pigment Epithelial Cells: Potential Therapeutic Avenues for Age-Related Macular Degeneration. Int J Mol Sci 2019; 20:E3367. [PMID: 31323999 PMCID: PMC6651864 DOI: 10.3390/ijms20133367] [Citation(s) in RCA: 26] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2019] [Revised: 07/03/2019] [Accepted: 07/05/2019] [Indexed: 12/21/2022] Open
Abstract
Oxidative stress-induced damage to the retinal pigmented epithelium (RPE), a specialised post-mitotic monolayer that maintains retinal homeostasis, contributes to the development of age-related macular degeneration (AMD). Curcumin (Cur), a naturally occurring antioxidant, was previously shown to have the ability to protect RPE cells from oxidative stress. However, poor solubility and bioavailability makes Cur a poor therapeutic agent. As prodrug approaches can mitigate these limitations, we compared the protective properties of the Cur prodrug curcumin diethyl disuccinate (CurDD) against Cur in relation to oxidative stress induced in human ARPE-19 cells. Both CurDD and Cur significantly decreased H2O2-induced reactive oxygen species (ROS) production and protected RPE cells from oxidative stress-induced death. Both drugs exerted their protective effects through the modulation of p44/42 (ERK) and the involvement of downstream molecules Bax and Bcl-2. Additionally, the expression of antioxidant enzymes HO-1 and NQO1 was also enhanced in cells treated with CurDD and Cur. In all cases, CurDD was more effective than its parent drug against oxidative stress-induced damage to ARPE-19 cells. These findings highlight CurDD as a more potent drug compared to Cur against oxidative stress and indicate that its protective effects are exerted through modulation of key apoptotic and antioxidant molecular pathways.

Abstract
Accumulating evidence has demonstrated that human cancers arise from various tissues of origin that initiate from cancer stem cells (CSCs) or cancer-initiating cells. The extrinsic and intrinsic apoptotic pathways are dysregulated in CSCs, and these cells play crucial roles in tumor initiation, progression, cell death resistance, chemo- and radiotherapy resistance, and tumor recurrence. Understanding CSC-specific signaling proteins and pathways is necessary to identify specific therapeutic targets that may lead to the development of more efficient therapies selectively targeting CSCs. Several signaling pathways-including the phosphatidylinositol 3-kinase (PI3K)/Akt/mammalian target of rapamycin (mTOR), maternal embryonic leucine zipper kinase (MELK), NOTCH1, and Wnt/Β-catenin&and expression of the CSC markers CD133, CD24, CD44, Oct4, Sox2, Nanog, and ALDH1A1 maintain CSC properties. Studying such pathways may help to understand CSC biology and lead to the development of potential therapeutic interventions to render CSCs more sensitive to cell death triggered by chemotherapy and radiation therapy. Moreover, recent demonstrations of dedifferentiation of differentiated cancer cells into CSC-like cells have created significant complexity in the CSCs hypothesis. Therefore, any successful therapeutic agent or combination of drugs for cancer therapy must eliminate not only CSCs but differentiated cancer cells and the entire bulk of tumor cells. This review article expands on the CSC hypothesis and paradigm with respect to major signaling pathways and effectors that regulate CSC apoptosis resistance. Moreover, selective CSC apoptotic modulators and their therapeutic potential for making tumors more responsive to therapy are discussed. The use of novel therapies, including small-molecule inhibitors of specific proteins in signaling pathways that regulate stemness, proliferation and migration of CSCs, immunotherapy, and noncoding microRNAs may provide better means of treating CSCs.

Sulforaphane-cysteine-induced apoptosis via phosphorylated ERK1/2-mediated maspin pathway in human non-small cell lung cancer cells. Cell Death Discov 2017; 3:17025. [PMID: 28690874 PMCID: PMC5494314 DOI: 10.1038/cddiscovery.2017.25] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2017] [Revised: 03/27/2017] [Accepted: 04/04/2017] [Indexed: 12/14/2022] Open
Abstract
Sulforaphane (SFN) was demonstrated to induce apoptosis in a variety of cancers via multiple mechanisms. However, owing to a short half-life in circulation, SFN was not used for clinical treatment yet. Interestingly, SFN analog, sulforaphane-cysteine (SFN-Cys) has a longer half-life in metabolism, and we previously demonstrated that SFN-Cys inhibited invasion in human prostate cancer cells. Here, we would investigate whether SFN-Cys induces apoptosis and find the underlying mechanisms in human non-small cell lung cancer (NSCLC) cells. Western blots were used to test the molecular linkages among extracellular signal-regulated kinases 1/2 (ERK1/2) and downstream signal molecules. Flow cytometry and fluorescence microscopy were used to detect cell death. Cell proliferation assay showed that SFN-Cys inhibited cell viability following a dose-dependent manner. Abnormal cell morphology was viewed after the cells were exposed to SFN-Cys. Flow cytometry showed that SFN-Cys induced cell apoptosis via a dose-dependent manner. Further, SFN-Cys triggered the activation of ERK1/2, which resulted in the upregulation of maspin, Bax, cleaved caspase-3 and downregulation of pro-caspase-3, Bcl-2, α-tubulin. Meanwhile, we demonstrated that recombinant caspase-3 cleaved α-tubulin in the lysate of cells, which were treated by SFN-Cys. These data indicated that SFN-Cys activated the ERK1/2-mediated mitochondria signaling pathway with maspin upregulation and α-tubulin downregulation leading to apoptosis. These findings will help to develop a novel therapeutic to target NSCLC cells.

Abstract
Skin cancer is the most common form of cancer responsible for considerable morbidity and mortality, the treatment progress of which remains slow though. Therefore, studies identifying anti-skin cancer agents that are innocuous are urgently needed. α-Mangostin, a natural product isolated from the pericarp of mangosteen fruit, has potent anti-cancer activity. However, its role in skin cancer remains unclear. The aim of this study was to evaluate the treatment effect of α-mangostin on skin tumorigenesis induced by 9,10-dimethylbenz[a]anthracene (DMBA)/TPA in mice and the potential mechanism. Treatment with α-mangostin significantly suppressed tumor formation and growth, and markedly reduced the incidence rate. α-Mangostin not only inhibited the expressions of pro-inflammatory factors, but also promoted the production of anti-inflammatory factors in tumor and blood. It induced autophagy of skin tumor and regulated the expressions of autophagy-related proteins. The protein expressions of LC3, LC3-II and Beclin1 increased whereas those of LC3-I and p62 decreased after treatment with α-mangostin. Moreover, α-mangostin promoted the apoptosis of skin tumor dose-dependently by up-regulating of Bax, cleaved caspase-3, cleaved PARP and Bad, and down-regulating of Bcl-2 and Bcl-xl. Furthermore, showed α-mangostin inhibited the PI3K/AKT/mTOR (mammalian target of rapamycin) signaling pathway, as evidenced by decreased expressions of phospho-PI3K (p-PI3K), p-Akt and p-mTOR, but did not affect the expressions of t-PI3K, t-Akt or t-mTOR. Collectively, α-mangostin suppressed murine skin tumorigenesis induced by DMBA/TPA through inhibiting inflammation and promoting autophagy and apoptosis by regulating the PI3K/Akt/mTOR signaling pathway, as a potential candidate for future clinical therapy.

Abstract
Background: Cissus quadrangularis Linn. (CQ) commonly known as Hadjod (Family: Vitaceae) is usually distributed in India and Sri Lanka and contains several bioactive compounds responsible for various metabolic and physiologic effects. Objective: In this study, the biological effects of CQ ethanolic extract were evaluated by in vitro and supported by in silico analysis on KB oral epidermoid cancer cell line. Materials and Methods: Anti-cancer potential of ethanolic extract of CQ stem against KB oral epidermoid cancer cells was evaluated in terms of morphological analysis, nuclei staining, liberation of reactive oxygen species (ROS), cell cycle arrest, mitochondrial membrane potential (MMP) and p53 and Bcl-2 protein expression which reveal the induction of apoptosis along with supporting in silico analysis. Results: Ethanolic extract of CQ stem contains various bioactive compounds responsible for cancer cell morphological alterations, liberation of ROS, G1 phase cell cycle arrest and decreased MMP along with up-regulation of p53 and down-regulation of Bcl-2. By employing in silico approach, we have also postulated that the CQ extract active constituents sequester Bcl-2 with higher affinity as compared to p53, which may be the reason for induction of growth arrest and apoptosis in KB cells. Conclusion: Our data indicate that the CQ extract has a remarkable apoptotic effect that suggests that it could be a viable treatment option for specific types of cancers. SUMMARY Cissus quadrangularis stem ethanolic extract induces apoptosis and cell cycle arrest at G1 phase It liberates (ROS) and mitochondria mediated apoptosis It upregulates p53 and down-regulates Bcl-2 protein expression In silico studies indicates that the active constituents of CQ binds Bcl-2 with higher affinity as compared to p53.

Abstract
Flavonoids have been reported to exhibit prooxidant cytotoxicity against cancer cells, but the underlying mechanism is still poorly understood. Here we investigated the potential mechanism that p53-inducible gene 3 (PIG3), a NADPH:quinone oxidoreductase, mediated the prooxidant cytotoxicity of flavonoids on human hepatoma HepG2 cells. The results showed that flavonoids (apigenin, luteolin, kaempferol, and quercetin) inhibited the growth of HepG2 cells in a dosage- and time-dependent manner, and induced the morphological changes characteristic of apoptosis in HepG2 cells. We also found that expression of PIG3 was increased markedly in HepG2 cells treated with flavonoids at both mRNA and protein levels, which was accompanied by increased intracellular ROS production and a decreased mitochondrial membrane potential (ΔΨm). All these effects were largely reversed through knockdown of the PIG3 gene in HepG2 cells. Western blotting indicated that flavonoids increased cytochrome c release, upregulated the ratio of Bax/Bcl-2, and activated the caspases-9 and -3. Moreover, knockdown of PIG3 could reverse the changes of these apoptotic-related proteins. These results suggest that PIG3 plays an important role in regulating the prooxidant activity and apoptosis-inducing action of flavonoids on HepG2 cells though the ROS-triggered mitochondrial apoptotic pathway.

Abstract
OBJECTIVES This report highlights phytoconstituents present in Cissus quadrangularis (CQ) extract and examines biphasic (proliferative and anti-proliferative) effects of its extract on bone cell proliferation, differentiation, mineralization, ROS generation, cell cycle progression and Runx2 gene expression in primary rat osteoblasts. MATERIALS AND METHODS Phytoconstituents were identified using gas chromatography-mass spectroscopy (GC-MS). Osteoblasts were exposed to different concentrations (10-100 μg/ml) of CQ extract and cell proliferation and cell differentiation were investigated at different periods of time. Subsequently, intracellular ROS intensity, apoptosis and matrix mineralization of osteoblasts were evaluated. We performed flow cytometry for DNA content and real-time PCR for Runx2 gene expression analysis. RESULTS CQ extract's approximately 40 bioactive compounds of fatty acids, hydrocarbons, vitamins and steroidal derivatives were identified. Osteoblasts exposed to varying concentrations of extract exhibited biphasic variation in cell proliferation and differentiation as a function of dose and time. Moreover, lower concentrations (10-50 μg/ml) of extract slightly reduced ROS intensity, although they enhanced matrix mineralization, DNA content in S phase of the cell cycle, and levels of Runx2 expression. However, higher concentrations (75-100 μg/ml) considerably induced the ROS intensity and nuclear condensation in osteoblasts, while it reduced mineralization level, proportion of cells in S phase and Runx2 level of the osteogenic gene. CONCLUSIONS These findings suggest that CQ extract revealed concentration-dependent biphasic effects, which would contribute notably to future assessment of pre-clinical efficacy and safety studies.
