Abstract
Diorganotin complexes of the compositions [Me2Sn(L)] (1), [n-Bu2Sn(L)] (2), [Ph2Sn(L)]⋅C6H6 (3), [Bz2Sn(L)]⋅C6H6 (4) and [n-Oct2Sn(L)] (5) were synthesized by reacting R2SnO (R = Me, n-Bu, Ph, Bz or n-Oct) with the N2,N6-di(thiazol-2-yl)pyridine-2,6-dicarboxamide (H2L, where H2 denotes the two acidic protons) in refluxing toluene. Additionally, the mono-n-butyltin complex [n-BuSn(HL)Cl2]·H2O (6) was synthesized from n-BuSnCl3 and H2L in acetonitrile. Compounds were characterized by FT-IR, 1H, 13C and 119Sn NMR spectroscopy, while their solid-state structures were examined using single-crystal X-ray diffraction studies. In diorganotin compounds 1-5, the dianionic tridentate ligands (Npy, N-, N-) act as κ-N3 chelators. In 6, the L moiety (O, Npy, N-) acts as a κ-ON2 tridentate chelator, with involvement of one of the carboxamide oxygen atoms. The coordination polyhedron around the Sn(IV) ion is completed either by two axial Sn-R ligands in compounds 1-5 or by n-Bu and Cl ligands in compound 6, giving rise to distorted trigonal bipyramid or octahedral structures, respectively. The tin NMR results show that the penta-coordinated structures of compounds 1-5 and the hexacoordinated structure of compound 6, observed in the solid-state, are retained in solution. The in vitro antitumor activities of 1-5 were tested on T-47D breast cancer cells. Of these, diphenyltin compound 3 showed the highest anti-proliferative effect, with an IC50 of 10 ± 1.60 μM. Compound 3 exhibited selective toxicity, potentially inducing apoptosis via reactive oxygen species generation and nuclear changes, indicating promise as a breast cancer treatment. This study is the first to explore thiazole-appended organotin compounds for cytotoxicity.

B13, a well-tolerated inhibitor of hedgehog pathway, exhibited potent anti-tumor effects against colorectal carcinoma in vitro and in vivo. Bioorg Chem 2023; 135:106488. [PMID: 36989734 DOI: 10.1016/j.bioorg.2023.106488] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2022] [Revised: 03/02/2023] [Accepted: 03/18/2023] [Indexed: 03/29/2023]
Abstract
Abnormal activation of Hedgehog (Hh) signaling pathway mediates the genesis and progression of various tumors [1]. Currently, three drugs targeting the Hh signaling component Smoothened (Smo) have been marketed for the clinical treatment of basal cell tumors or acute myeloid leukemia. However, drug resistance is a common problem in those drugs, so the study of Smo inhibitors that can overcome drug resistance has important guiding significance for clinical adjuvant drugs. MTT assay, clone formation assay and EdU assay were used to detect the proliferation inhibitory activity of the drugs on tumor cells. The effect of B13 on cell cycle and apoptosis were detected by flow cytometry. An acute toxicity test was used to detect the toxicity of B13 in vivo, and xenograft tumor model was used to detect the efficacy of B13 in vivo. The binding of B13 to Smo was studied by BODIPY-cyclopamine competitive binding assay and molecular docking. The effect of B13 on the expression and localization of downstream target gene Gli1/2 of Smo was investigated by Western Blot and immunofluorescence assay. SmoD473H mutant cell line was constructed to study the effect of B13 against drug resistance. (1) B13 had the strongest inhibitory activity against colorectal cancer cells. (2) B13 can effectively inhibit the clone formation and EdU positive rate of colon cancer cells. (3) B13 can block the cell cycle in the G2/M phase and cell apoptosis. (4) B13 has low toxicity in vivo, and its efficacy in vivo is better than that of the Vismodegib. (5) Molecular docking and BODIPY-cyclopamine experiments showed that B13 could bind to Smo protein. (6) B13 can inhibit the protein expression of Gli1, the downstream of Smo, and inhibit its entry into the nucleus. (7) B13 could inhibit the expression of Gli1 in the HEK293 cells with SmoD473H, and the molecular docking results showed that B13 could bind SmoD473H protein. B13 with the best anti-tumor activity was screened out by MTT assay. In vitro, pharmacodynamics experiments showed that B13 could effectively inhibit the proliferation and metastasis of colorectal cancer cells, induce cell cycle arrest, and induce cell apoptosis. In vivo pharmacodynamics experiments showed that B13 was superior to Vismodegib in antitumor activity and had low toxicity in vivo. Mechanism studies have shown that B13 can bind Smo protein, inhibit the expression of downstream Gli1 and its entry into the nucleus. Notably, B13 overcomes resistance caused by SmoD473H mutations.

Triphenyltin(IV) dithiocarbamate compound induces genotoxicity and cytotoxicity in K562 human erythroleukemia cells primarily via mitochondria-mediated apoptosis. Food Chem Toxicol 2022; 168:113336. [PMID: 35963475 DOI: 10.1016/j.fct.2022.113336] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2021] [Revised: 06/25/2022] [Accepted: 07/27/2022] [Indexed: 11/22/2022]
Abstract
The novel di-and triphenyltin(IV) dithiocarbamate compounds represented as RnSnL2 (where R = C4H9, C6H5; n = 2,3; L = N,N-dithiocarbamate), Ph2Sn(N,N-diisopropyldithiocarbamate) (OC1), Ph3Sn(N,N-diisopropyldithiocarbamate) (OC2), Ph2Sn(N,N-diallyldithiocarbamate) (OC3), Ph3Sn(N,N-diallyldithiocarbamate) (OC4), and Ph2Sn(N,N-diethyldithiocarbamate) (OC5) were assessed for their cytotoxicity in K562 human erythroleukemia cells. All compounds inhibited the growth of cells at low micromolar concentrations (<10 μM), and the mechanism underlying their antiproliferative effects on K562 cells was apoptosis, as corroborated by the exposure of plasma membrane phosphatidylserine. OC2, which showed the most promising antiproliferative activity, was selected for further analyses. The results demonstrated that OC2 induced apoptosis in K562 cells via an intrinsic mitochondrial pathway triggered upon DNA damage, an early apoptotic signal. Subsequently, OC2 produced excessive intracellular reactive oxygen species. The role of oxidative stress was corroborated by the significant reduction in GSH levels and percentage of apoptosis in NAC-pretreated cells. OC2 could arrest the cell cycle progression in the S phase. These new findings elucidate the antiproliferative potential of OC2 in the K562 human erythroleukemia cells and warrant further investigation, specifically to determine the exact signaling pathway underlying its antileukemic efficacy.

Abstract
Organotin (IV) compounds are a focus of research for potential use in cancer chemotherapy. Here, we established anticancer profile of dibutyltin (IV) carboxylate derivatives in prostate cancer (PCa) model. We determined cytotoxicity of a library of dibutyltin (IV) carboxylate derivatives and observed that dibutylstannanediyl (2Z,2'Z)-bis(4-(benzylamino)-4-oxobut-2-enoate (Ch-620; 10 μM) was minimally toxic to normal fibroblasts. Ch-620 (1-1.25 μM) inhibited proliferation of PCa and melanoma cells on short- and long-term exposures with induction of cell cycle arrest. Ch-620 treatment increased population of apoptotic cells, as assessed by flow cytometry, and activated caspase 3. Proteomics showed activation of PPARα, with repression of SMAD4 and integrin β5 (ITGB5) in Ch-620-treated PCa cells. Further analysis demonstrated that Ch-620 resulted in phosphorylation of p38 MAPK, upregulation of PPARα and decreased expression of SMAD4 and ITGB5 with reduced migration of PCa cells. In vivo studies in PC3M grafted athymic nude mice showed that Ch-620 (5 μg/week; 7 weeks) treatment reduced tumor growth as opposed to untreated controls. Immunoblot analysis of tumors demonstrated upregulated p-p38 MAPK and PPARα, followed by a decline in SMAD4 and ITGB5. Immunohistochemistry reinforced these results with increased caspase 3 and p-p38 MAPK and diminished Ki67 staining in Ch-620 treated animals. Taken together, our data indicate that Ch-620 inhibited proliferation of PCa through modulation of MAPK/PPARα/SMAD4 signaling. Organotin (IV) carboxylate compounds; specifically Ch-620 can be a potential anticancer agent for the treatment of PCa subject to detailed pre-clinical and clinical investigations. This unlocks prospects for the development of new tin-based drugs in cancer therapeutics.

Abstract
Cancer is a leading cause of morbidity and mortality worldwide. The development of cancer involves aberrations in multiple pathways, representing promising targets for anti-cancer drug discovery. Natural products are regarded as a rich source for developing anti-cancer therapies due to their unique structures and favorable pharmacology and toxicology profiles. Deoxyelephantopin and isodeoxyelephantopin, sesquiterpene lactone compounds, are major components of Elephantopus scaber and Elephantopus carolinianus, which have long been used as traditional medicines to treat multiple ailments, including liver diseases, diabetes, bronchitis, fever, diarrhea, dysentery, cancer, renal disorders, and inflammation-associated diseases. Recently, deoxyelephantopin and isodeoxyelephantopin have been extensively explored for their anti-cancer activities. This review summarizes and discusses the anti-cancer activities of deoxyelephantopin and isodeoxyelephantopin, with an emphasis on their modes of action and molecular targets. Both compounds disrupt several processes involved in cancer progression by targeting multiple signaling pathways deregulated in cancers, including cell cycle and proliferation, cell survival, autophagy, and invasion pathways. Future directions of research on these two compounds towards anti-cancer drug development are discussed.

Abstract
Organotin(IV) compounds have wide applications in industrial and agricultural fields owing to their ability to act as poly(vinyl chloride) stabilizers and catalytic agents as well as their medicinal properties. Moreover, organotin(IV) compounds may have applications as antitumor, anti-inflammatory, antifungal, or antimicrobial agents based on the observation of synergistic effects following the binding of their respective ligands, resulting in the enhancement of their biological activities. In this review, we describe the antiproliferative activities of organotin(IV) compounds in various human cancer cell lines based on different types of ligands. We also discuss the molecular mechanisms through which organotin(IV) compounds induce cell death via apoptosis through the mitochondrial intrinsic pathway. Finally, we present the mechanisms of cell cycle arrest induced by organotin(IV) compounds. Our report provides a basis for studies of the antitumor activities of organotin(IV) compounds and highlights the potential applications of these compounds as anticancer metallodrugs with low toxicity and few side effects.

Abstract
Cadmium (Cd) and copper (Cu) are widely present in foods. However, their adverse effects on human gastric epithelium are not fully understood. Here, human gastric epithelial cells (SGC-7901) were employed to study the toxicity and associated mechanisms of Cd + Cu co-exposure. Their effects on cell viability, morphology, oxidative damage, cell cycle, apoptosis, and the mRNA levels of antioxidases and cell cycle regulatory genes were investigated. Co-exposure to Cd (5 μM)/Cu (10 μM) induced >40% cell viability loss, whereas little effect on cell viability at <10 μM Cd or 40 μM Cu. Compared to individual exposure, co-exposure induced greater oxidative damage by elevating ROS (3.5 folds), malondialdehyde (2.3 folds) and expression of SOD1 and HO-1 besides inhibiting CAT, GPX1 and Nrf2. A marked S cell-cycle arrest was observed in co-exposure, evidenced by more cells staying in the S phase (36%), up-regulation of cyclins-dependent kinase (CDK4) and CDKs inhibitor (p21) and down-regulation of CDK2, CDK6 and p27. Furthermore, higher apoptosis (22%) with floated and round cells occurred in co-exposure group. Our data implicate the cytotoxicity of Cd + Cu co-exposure was higher than individual exposure, and individual assessment would underestimate their potential health risk. Oxidative stress and cell cycle arrest possibly played a role in Cd + Cu induced toxicity and apoptosis in SGC-7901 cells. Our data suggest the importance to reduce Cd in foods to decrease its adverse impacts on human digestive system.

Abstract
Vincamine, a well-known plant alkaloid, has been used as a dietary supplement and as a peripheral vasodilator to combat aging in humans. In this study, for the very first time, we demonstrated that vincamine can function as an anticancer agent in a human alveolar basal epithelial cell line A549 (IC50 = 309.7 μM). The anticancer potential of vincamine in A549 cells was assessed by molecular assays to determine cell viability, generation of intracellular ROS, nuclear condensation, caspase-3 activity and inhibition, and change in mitochondrial membrane potential (ΔΨm). In silico studies predicted that the anti-proliferative potential of vincamine is enhanced by its interaction with the apoptotic protein caspase-3, and that this interaction is driven by two hydrogen bonds and has a high free energy of binding (-5.64 kcal/mol) with an estimated association constant (Ka) of 73.67 μM. We found that vincamine stimulated caspase-3-dependent apoptosis and lowered mitochondrial membrane potential, which ultimately led to cytochrome C release. Vincamine was also found to quench hydroxyl free radicals and deplete iron ions in cancer cells. As a dietary supplement, vincamine is almost non-toxic in BEAS-2B and 3T3-L1 cells. Therefore, we propose that vincamine represents a safe anticancer agent in lung cancer cells. Its role in other cancers has yet to be explored.

Abstract
Increasing knowledge of the relationship between cancer and dysregulated polyamine catabolism suggests interfering with aberrant polyamine metabolism for anticancer therapy that will have considerable clinical promise. SMO (spermine oxidase) plays an essential role in regulating the polyamines homeostasis. Therefore, development of SMO inhibitors has increasingly attracted much attention. Previously, we successfully purified and characterised SMO. Here, we presented an in silico drug discovery pipeline by combining pharmacophore modelling and molecular docking for the virtual screening of SMO inhibitors. In vitro evaluation showed that N-(3-{[3-(dimethylamino)propyl]amino}propyl)-8-quinolinecarboxamide (SI-4650) inhibited SMO enzyme activity, increased substrate spermine content and reduced product spermidine content, indicating that SI-4650 can interfere with polyamine metabolism. Furthermore, SI-4650 treatment suppressed cell proliferation and migration. Mechanistically, SI-4650 caused cell cycle arrest, induced cell apoptosis, and promoted autophagy. These results demonstrated the properties of interfering with polyamine metabolism of SI-4650 as a SMO inhibitor and the potential for cancer treatment.

Abstract
The present study aimed to determine the effect of Twist downregulation on the proliferation, apoptosis and migration of human endometrial carcinoma Ishikawa cells. Endogenous expression of the Twist transcription factor was knocked down by delivery of Twist-targeting small interfering RNA (siRNA). Changes in the expression of epithelial-mesenchymal transition biomarkers, namely epithelial (E)-cadherin, neural (N)-cadherin and Twist, were determined by western blot analysis. Cell cycle distribution and apoptosis were evaluated by flow cytometry. Cell proliferation and migration were analyzed using cell-counting and wound-healing assays, respectively. Transfection with Twist siRNA led to a significant reduction in the expression of Twist and N-cadherin (P<0.05), while significantly increasing the expression of E-cadherin, relative to negative control transfectants (all P<0.05). Proliferation was also significantly decreased in Ishikawa cells transfected with Twist siRNA (P<0.05), which was accompanied by an increased rate of apoptosis and cell cycle arrest at S-phase. In addition, Twist downregulation led to a significant reduction in cell migration (P<0.05). These data suggest that Twist serves a role in the regulation of cell proliferation and migration in Ishikawa cells and may represent a potential target for the treatment of human endometrial carcinoma.

Abstract
Purpose: To evaluate the changes of caveolin-1 in lung fibroblasts in newborn Wistar rats when exposed to hyperoxic conditions, as well as lung fibroblasts cell cycle. Methods: One hundred newborn Wistar rats were randomly divided (50 rats/group) into experimental and control groups, exposed to hyperoxic conditions or normal air, respectively. The fraction of inspired oxygen (FiO2) in the experimental group was 90%, whereas this value was 21% in the control group. Lung fibroblasts were collected on days 3, 7, and 14 of the experiment. Caveolin-1 expression dynamics in lung fibroblasts was assayed in each group by immunofluorescence and Western blot analyses. Flow cytometry (FCM) was used to assess the proportions of lung fibroblasts at different stages of the cell cycle. Results: On day 3, no significant difference in caveolin-1 expression was observed between the hyperoxic and control groups; however, on days 7 and 14, caveolin-1 expression was significantly lower in the hyperoxic group than in the control (P<0.05). No apparent differences were observed in caveolin-1 expression in the control group at the different time points. Using FCM analysis, we showed that the proportion of lung fibroblasts in G0/G1 phase in the hyperoxic group decreased compared to that of the control group on day 7, while the proportion of S-phase cells increased (P<0.05). These differences were more significant when the groups were compared on day 14 (P<0.01). Conclusion: After seven days the exposure to hyperoxic conditions, lung fibroblasts proliferated and caveolin-1 expression decreased.

Zeylenone, a naturally occurring cyclohexene oxide, inhibits proliferation and induces apoptosis in cervical carcinoma cells via PI3K/AKT/mTOR and MAPK/ERK pathways. Sci Rep 2017; 7:1669. [PMID: 28490807 PMCID: PMC5431878 DOI: 10.1038/s41598-017-01804-2] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2016] [Accepted: 03/31/2017] [Indexed: 01/22/2023] Open
Abstract
There is a strong rationale to therapeutically target the PI3K/Akt/mTOR and MAPK/ERK pathways in cervical carcinoma since they are highly deregulated in this disease. Previous study by our group have demonstrated that Zeylenone (Zey) exhibited strong suppressive activity on PI3K/AKT/mTOR and MAPK/ERK signaling, providing a foundation to investigate its antitumor activity in cervical carcinoma. Herein, the present study aimed to investigate suppressive effect of Zey on HeLa and CaSki cells, and further explore the underlying mechanisms. Cells were treated with Zey for indicated time, followed by measuring its effects on cell viability, colony formation, cell cycle, cell apoptosis, and signal pathways. In vivo antitumor activity of Zey was then assessed with nude xenografts. We found that Zey substantially suppressed cell proliferation, induced cell cycle arrest, and increased cell apoptosis, accompanied by increased production of ROS, decreased mitochondrial membrane potential, activated caspase apoptotic cascade, and attenuated PI3K/Akt/mTOR and MAPK/ERK pathways. Additionally, in vivo experiments showed that Zey exerted good antitumor efficacy against HeLa bearing mice models via decreasing levels of p-PI3K and p-ERK. Collectively, these data clearly demonstrated the antitumor activity of Zey in cervical carcinoma cells, which is most likely via the regulation of PI3K/Akt/mTOR and MAPK/ERK pathways.

Abstract
Honokiol (C18H18O2) is a biphenolic natural product isolated from the bark and leaves of Magnolia plant spp. During the last decade or more, honokiol has been extensively studied for its beneficial effect against several diseases. Investigations have demonstrated that honokiol possesses anti-carcinogenic, anti-inflammatory, anti-oxidative, anti-angiogenic as well as inhibitory effect on malignant transformation of papillomas to carcinomas in vitro and in vivo animal models without any appreciable toxicity. Honokiol affects multiple signaling pathways, molecular and cellular targets including nuclear factor-κB (NF-κB), STAT3, epidermal growth factor receptor (EGFR), cell survival signaling, cell cycle, cyclooxygenase and other inflammatory mediators, etc. Its chemopreventive and/or therapeutic effects have been tested against chronic diseases, such as cancers of different organs. In this chapter, we describe and discuss briefly the effect of honokiol against cancers of different organs, such as melanoma, non-melanoma, lung, prostate, breast, head and neck squamous cell carcinoma, urinary bladder cancer, gastric cancer, and neuroblastoma, etc. and describe its mechanism of action including various molecular and cellular targets. Although more rigorous in vivo studies are still needed, however it is expected that therapeutic effects and activities of honokiol may help in the development and designing of clinical trials against chronic diseases in human subjects.

Abstract
BACKGROUND Medullary thyroid carcinoma (MTC) constitutes approximately 5 % of all thyroid cancers and carries a worse prognosis than other differentiated thyroid cancers. Targeted therapies are being investigated for systemic treatment of MTC. Ubiquitin-specific peptidase 39 (USP39) functions in pre-mRNA splicing as a component of the U4/U6-U5 tri-snRNP and also participates in spindle checkpoint and cytokinesis. In this study, we aimed to evaluate the potential role in MTC. METHODS We used lentivirus-delivered short hairpin RNA (shRNA) to silence USP39 expression in one MTC cell line TT. USP39 expression was detected by qPCR and Western blot. For functional analysis, MTT assay was performed to evaluate the proliferation activity, and FACS was used to assess the cell distribution in the cell cycle. Moreover, the expressions of cell cycle-related proteins were examined by Western blot. RESULTS Both two shRNA sequences against USP39 could efficiently reduce its expression in TT cells. Knockdown of USP39 significantly decreased cell proliferation and caused cell cycle arrest at G2/M phase. Moreover, G2/M phase-associated proteins, Cyclin B1 and CDK1, were obviously down-regulated in TT cells after USP39 silencing. CONCLUSIONS Therefore, knockdown of USP39 is likely to provide a novel alternative to targeted therapy of MTC and deserves further investigation.

Abstract
OBJECTIVE Previous studies have shown that Fructus Ligustri Lucide (FLL) can be used to anti-cancer. However, the mechanism by which FLL mediate this effect is unclear. In the present study, aqueous extracts of FLL induced cell apoptosis in human gastric carcinoma cell was investigated. METHODS The cell viability was detected by the CCK8 assay. The cell apoptosis was assessed by annexin V-PI double-labeling staining and hoechst 33342 staining. The protein expression of cell cycle regulators and tumor suppressors were analyzed by western blotting. RESULTS Treatment of human gastric carcinoma cells with FLL induced cell death in a dose- and time-dependent manner by using CCK8 assay. Consistent with the CCK8 assay, the flow cytometry results showed that the proportion of the early and terminal phase of apoptosis cells had gained after FLL treatment as compared to untreated group. Moreover, human gastric carcinoma cells were exposed to the aqueous extracts of FLL for 48 h, which resulted in an accumulation of cells in G2/M phase. Apoptotic bodies were clearly observed in human gastric carcinoma that had been treated with FLL for 48 h and then stained with Hochest 33342. Treatment of gastric carcinoma cells with increasing doses of FLL and increasing durations significantly increased the protein expression of Bax and Caspase3, decreased the anti-apoptotic Bcl-2 level. The expression of CDC2 and cdc25C were downregulated upon FLL treatment in human gastric carcinoma. In contrast, p53 and p21 were obviously upregulated by FLL treatment in a concentration-dependent manner. CONCLUSIONS These results confirmed that FLL could induce apoptosis in human gastric carcinoma, the underlying molecular mechanisms, at least partially, through activation p21/p53 and suppression CDC2/cdc25C signaling in vitro.

Abstract
S-adenosylhomocysteine hydrolase (AHCY) hydrolyzes S-adenosylhomocysteine to adenosine and l-homocysteine, and it is already known that inhibition of AHCY decreased cell proliferation by G2/M arrest in MCF7 cells. However, the previous study has not indicated what mechanism the cell cycle arrest is induced by. In this study, we aimed to investigate the different cell cycle mechanisms in both p53 wild-typed MCF7 and p53 mutant-typed MCF7-ADR by suppressing AHCY. We extensively proved that AHCY knockdown has an anti-proliferative effect by using the WST-1 assay, BrdU assay, and cell cytometry analysis and an anti-invasive, migration effect by wound-healing assay and trans-well analysis. Our study showed that down-regulation of AHCY effectively suppressed cell proliferation by regulating the MEK/ERK signaling pathway and through cell cycle arrests. The cell cycle arrest occurred at the G2/M checkpoint by inhibiting degradation of cyclinB1 and phosphorylation of CDC2 in MCF7 cells and at the G1 phase by inhibiting cyclinD1 and CDK6 in MCF7-ADR cells. Finally, we determined that AHCY regulates the expression of ATM kinase that phosphorylates p53 and affects to arrest of G2/M phase in MCF7 cells. The findings of this study significantly suggest that AHCY is an important regulator of cell proliferation through different mechanism in between MCF7 and MCF7-ADR cells as p53 status.

Abstract
OBJECTIVE Gastric carcinoma is a malignant tumor that responds poorly to both chemotherapy and radiation therapy. In our study, we investigated the anti-cancer effect of honokiol, an active component isolated and purified from the Magnolia officinalis, in human gastric carcinoma MGC-803 cell line. METHODS The cell viability was detected by the CCK8 assay. The cell apoptosis and cell cycle arrest were assessed by flow cytometer. The protein expression of cell cycle regulators and tumor suppressors were analyzed by western blotting. RESULTS Treatment of human gastric carcinoma cells with honokiol induced cell death in a dose-and time-dependent manner by using CCK8 assay. Consistent with the CCK8 assay, the flow cytometry results showed that the proportion of apoptosis cells had gained when the cells were exposed to honokiol. Moreover, Cyclin B1, CDC2 and cdc25C were downregulated, and the expression of p-CDC2 and p-cdc25c was significantly upregulated upon honokiol treatment. P53 and p21 were significantly upregulated by honokiol treatment. Treatment of MGC-803 cells with honokiol significantly increased the pro-apoptotic Bax level and decreased the anti-apoptotic Bcl-2 level. CONCLUSIONS These results confirmed that honokiol could induce apoptosis and cell cycle arrest, the underlying molecular mechanisms, at least partially, through activation p53 signaling and downregulation CDC2/cdc25C expression.
