Abstract
Alloimperatorin (Alloi) has been shown to have anti-proliferative effects in our previous studies. we aimed to investigate whether Alloimperatorin induces autophagy through the reactive oxygen species (ROS) pathway and anticancer activity in vivo. The anti-proliferative effect of Alloimperatorin was evaluated using a cell counting kit (CCK-8 kit). Apoptosis was detected using flow cytometry. Confocal microscopy, immunofluorescence, and mRFP-GFP-LC3 lentivirus transfection were used to verify autophagy. Electron microscopy detection of autophagosomes was induced by Alloimperatorin. Western blotting was used to detect autophagy proteins in HeLa and SiHa cells. A xenograft model was used to monitor the inhibitory effect of Alloimperatorin on tumor growth in nude mice. The results showed that Alloimperatorin induced ROS production and inhibited the proliferation of HeLa and SiHa cells. Furthermore, Alloimperatorin increased the apoptosis rate in HeLa and SiHa cells. Confocal microscopy fluorescence indicated that Alloimperatorin increased autophagy fluorescence of HeLa and SiHa cells. mRFP-GFP-LC3 lentivirus transfection and electron microscopy demonstrated that Alloimperatorin increased autophagy in HeLa and SiHa cells. Western blotting showed that Alloimperatorin induced the expression of autophagy proteins in HeLa and SiHa cells. However, N-acetylcysteine reversed the autophagy. These results demonstrate that Alloimperatorin can induce autophagy in HeLa and SiHa cells through the ROS pathway. In vivo xenograft experiments showed that Alloimperatorin could inhibit tumor growth in nude mice. Alloimperatorin is expected to be an effective new drug for cervical cancer treatment.Abbreviations: ROS, reactive oxygen species; Alloi, Alloimperatorin; CCK-8, Cell Counting Kit-8; NAC, N-acetyl-L-cysteine; DCFH-DA, 2,7-dichlorodihydrofluorescein diacetate; OD, optical density; PBS, phosphate buffer solution; BCA, bicinchoninic acid; DAPI, 4,6-diamidino-2-phenylindole; DMSO, dimethyl sulfoxide.

Abstract
Mitotic catastrophe (MC) is a suppressive mechanism that mediates the elimination of mitosis-deficient cells through apoptosis, necrosis or senescence after M phase block. SIRT1 is involved in the regulation of several cellular processes, including autophagy. However, the relationship between SIRT1 and MC has been largely obscure. Our study highlights that SIRT1 might be involved in the regulation of MC. We have shown that degradation of the SIRT1 protein via proteasome and lysosomal pathway was accompanied by MC induced via BMH-21. Overexpression of SIRT1 alleviated MC by decreasing the proportion of apoptotic and multinuclear cells induced by G2/M block and triggered autophagy whereas knockdown of SIRT1 aggravated MC and repressed autophagy. Furthermore, we found that serum starvation triggered autophagy evidently generated lower MC whereas siRNA of ATG5/7 suppressed autophagy leading to higher MC. ChIP analysis revealed that SIRT1 could bind to the promoter of BubR1, a component of spindle assembly checkpoint (SAC), to upregulate its expression. Overexpression of BubR1 decreased MC whereas knockdown of BubR1 increased it. These results reveal that SIRT1 regulates MC through autophagy and BubR1 signaling, and provide evidence for SIRT1, autophagy and BubR1 being the potential cancer therapeutic targets.

Abstract
Fucoidan is a sulfated polysaccharide obtained from marine algae and known for various pharmacological activities. In this study, we investigated the effect of Fucoidan on cell viability, redox balance, cytoskeletal component F-actin, HDAC inhibition, autophagy, and senescence phenomenon in human cervical cancer HeLa cell line in comparison to positive control suberoylanilide hydroxamic acid by flow cytometry, fluorescence microscopy, and western blotting. Our observations revealed that Fucoidan exposure induces cytotoxicity in HeLa cells via ROS and mitochondrial superoxide generation and loss of ATP. Colorimetrical studies suggested that Fucoidan impairs the function of HDAC expression. Fucoidan treatment also contributes to the change in the granularity of cells, senescence-associated heterochromatin foci formation that leads to senescence in HeLa cells. Moreover, we visualize that Fucoidan exhibits autophagosomes formation with monodansylcadaverine, and flow cytometry analysis by acridine orange further substantiates that Fucoidan triggers autophagy in HeLa cells. Additionally, the changes in the expression of proteins p21, p16, BECN1, and HDAC1 were seen as markers of senescence, autophagy, and HDAC inhibition by FACS and immunoblotting. Molecular docking study validates Fucoidan-HDAC1 association in corroboration with the experimental data. Collectively, these mechanistic studies demonstrated that Fucoidan could be a therapeutic molecule for targeting HDACs in cervical cancer.

Abstract
Introduction The flavonol glycoside icariside II (ICA II) has been shown to exhibit a range of anti-tumor properties. Herein, we evaluated the impact of ICA II on human prostate cancer cell proliferation, motility, and autophagy, and we further evaluated the molecular mechanisms underlying these effects. Methods We treated DU145 human prostate cancer cells with a range of ICA II doses and then assessed their proliferation via CCK-8 assay, while flow cytometry was used to monitor apoptosis and cell cycle progression. We further utilized wound healing and transwell assays to probe the impact of ICA II on migration and invasion, and assessed autophagy via laser confocal fluorescence microscopy. Western blotting was further utilized to measure LC3-II/I, Beclin-1, P70S6K, PI3K, AKT, mTOR, phospho-AKT, phospho-mTOR, and phospho-P70S6K levels, with qRT-PCR being used to evaluate the expression of specific genes at the mRNA level. Results We found that ICA II was capable of mediating the dose- and time-dependent suppression of DU145 cell proliferation, causing these cells to enter a state of cell cycle arrest and apoptosis. We further determined that ICA II treatment was associated with significant impairment of prostate cancer cell migration and invasion, whereas autophagy was enhanced in treated cells relative to untreated controls. Conclusion Our results indicate that ICA II treatment is capable of suppressing human prostate tumor cell proliferation and migration while enhancing autophagy via modulating the PI3K-AKT-mTOR signaling pathway. As such, ICA II may be an ideal candidate drug for the treatment of prostate cancer.

Abstract
We have developed a versatile synthetic approach for the synthesis of new isoindole derivatives via the cleavage of ethers from tricyclic imide skeleton compounds. An exo-cycloadduct prepared from the Diels-Alder reaction of furan and maleic anhydride furnished imide derivatives. The epoxide ring was opened with Ac2O or Ac2O/AcCl in the presence of a catalytic amount of H2SO4 in order to yield new isoindole derivatives 8a-d and 9a-d. The anticancer activity of these compounds was evaluated against the HeLa cell lines. The synthesized compounds showed inhibitory effects on the viability of HeLa cells and the degree of cytotoxicity was increased with the level of bigger branched isoindole derivatives. To better understand the acting mechanism of these molecules, western blot analysis was performed with using mTOR and its downstream substrates. In addition, human mTOR and ribozomal S6 kinase β1 (RS6Kβ1) have been investigated with molecular modelling studies as possible targets for compound series 8 and 9.

Abstract
Angelicin is an active compound isolated from the Chinese herb Angelica archangelica, which has been reported to exert antitumor effects by inhibiting malignant behaviors in several types of tumor, including proliferation, colony formation, migration and invasion. However, the effects of angelicin on human cervical cancer cells is yet to be elucidated. The present study evaluated the antitumor effects of angelicin on cervical cancer cells. The results demonstrated that cervical cancer cells were more sensitive to angelicin than cervical epithelial cells. At its IC30, angelicin inhibited the proliferation of HeLa and SiHa cells by blocking the cell cycle at the G1/G0 phase and inhibiting other malignant behaviors, including colony formation, tumor formation in soft agar, migration and invasion. At the IC50, angelicin induced cell death potentially by promoting apoptosis. By identifying the hallmarks of autophagy, it was observed that angelicin treatment caused the accumulation of microtubule associated protein 1 light chain 3-β (LC3B) in the cytoplasm of HeLa and SiHa cells. Western blotting results demonstrated that cleaved LC3B-II and autophagy related proteins (Atg)3, Atg7 and Atg12-5 were upregulated following angelicin treatment. It was also determined that the phosphorylation of mTOR was induced by angelicin treatment. Furthermore, the inhibition of angelicin-induced mTOR phosphorylation did not disrupt its inhibitory effect on autophagy, indicating that angelicin inhibited autophagy in an mTOR-independent manner. Taken together, the present results suggested that angelicin regulated malignant behaviors in cervical cancer cells by inhibiting autophagy in an mTOR-independent manner. Findings suggested that autophagy might be a potential therapeutic target for cervical cancer.

Abstract
Bromophenol is a type of natural marine product. It has excellent biological activities, especially anticancer activities. In our study of searching for potent anticancer drugs, a novel bromophenol derivative containing indolin-2-one moiety, 3-(4-(3-([1,4′-bipiperidin]-1′-yl)propoxy)-3-bromo-5-methoxybenzylidene)-N-(4-bromophenyl)-2-oxoindoline-5-sulfonamide (BOS-102) was synthesized, which showed excellent anticancer activities on human lung cancer cell lines. A study of the mechanisms indicated that BOS-102 could significantly block cell proliferation in human A549 lung cancer cells and effectively induce G0/G1 cell cycle arrest via targeting cyclin D1 and cyclin-dependent kinase 4 (CDK4). BOS-102 could also induce apoptosis, including activating caspase-3 and poly (ADP-ribose) polymerase (PARP), increasing the Bax/Bcl-2 ratio, enhancing reactive oxygen species (ROS) generation, decreasing mitochondrial membrane potential (MMP, ΔΨm), and leading cytochrome c release from mitochondria. Further research revealed that BOS-102 deactivated the PI3K/Akt pathway and activated the mitogen-activated protein kinase (MAPK) signaling pathway resulting in apoptosis and cell cycle arrest, which indicated that BOS-102 has the potential to develop into an anticancer drug.

Abstract
A series of bromophenol hybrids with N-containing heterocyclic moieties were designed, and their anticancer activities against a panel of five human cancer cell lines (A549, Bel7402, HepG2, HCT116 and Caco2) using MTT assay in vitro were explored. Among them, thirteen compounds (17a, 17b, 18a, 19a, 19b, 20a, 20b, 21a, 21b, 22a, 22b, 23a, and 23b) exhibited significant inhibitory activity against the tested cancer cell lines. The structure-activity relationships (SARs) of bromophenol derivatives were discussed. The promising candidate compound 17a could induce cell cycle arrest at G0/G1 phase and induce apoptosis in A549 cells, as well as caused DNA fragmentations, morphological changes and ROS generation by the mechanism studies. Furthermore, compound 17a suppression of Bcl-2 levels (decrease in the expression of the anti-apoptotic proteins Bcl-2 and down-regulation in the expression levels of Bcl-2) in A549 cells were observed, along with activation caspase-3 and PARP, which indicated that compound 17a induced A549 cells apoptosis in vitro through the ROS-mediated apoptotic pathway. These results might be useful for bromophenol derivatives to be explored and developed as novel anticancer drugs.

Abstract
Oleic acid (OA), a main ingredient of Brucea javanica oil (BJO), is widely known to have anticancer effects in many tumors. In this study, we investigated the anticancer effect of OA and its mechanism in tongue squamous cell carcinoma (TSCC). We found that OA effectively inhibited TSCC cell proliferation in a dose- and time-dependent manner. OA treatment in TSCC significantly induced cell cycle G0/G1 arrest, increased the proportion of apoptotic cells, decreased the expression of CyclinD1 and Bcl-2, and increased the expression of p53 and cleaved caspase-3. OA also obviously induced the formation of autolysosomes and decreased the expression of p62 and the ratio of LC3 I/LC3 II. The expression of p-Akt, p-mTOR, p-S6K, p-4E-BP1 and p-ERK1/2 was significantly decreased in TSCC cells after treatment with OA. Moreover, tumor growth was significantly inhibited after OA treatment in a xenograft mouse model. The above results indicate that OA has a potent anticancer effect in TSCC by inducing apoptosis and autophagy via blocking the Akt/mTOR pathway. Thus, OA is a potential TSCC drug that is worthy of further research and development.

Abstract
Although Arctii Fructus (AF) has been shown to have various pharmacological effects, there have been no studies concerning the inhibitory effects of AF on the metastatic properties of colorectal cancer (CRC). The aim of this study was to investigate whether AF could suppress CRC progression by inhibiting cell growth, epithelial-mesenchymal transition (EMT), migration, and the invasion ability of CRC cells. AF decreased proliferation of CRC cells by inducing cell cycle arrest and apoptosis via extrinsic and intrinsic apoptotic pathways. Regarding metastatic properties, AF inhibited EMT by increasing the expression of the epithelial marker, E-cadherin, and decreasing the expression of the mesenchymal marker, N-cadherin, in CT26 cells. Moreover, AF decreased the migration and invasion of CT26 cells by inhibiting matrix metalloproteinase-2 (MMP-2) and MMP-9 activity. We confirmed that the decreased invasion ability and MMP-9 activity by AF treatment involved AMP-activated protein kinase (AMPK) activation. Collectively, this study demonstrates that AF inhibits the proliferation and metastatic properties of CRC cells.

Abstract
This study aims to investigate the function of long non-coding RNA ZEB1-AS1, reveal its molecular mechanism in colorectal cancer cell growth, and evaluate its clinical significance in colorectal cancer patients. ZEB1-AS1 has reported in the development of several cancers, but the biological role of it in colorectal cancer has not been discussed. In this report, ZEB1-AS1 expression level was measured with quantitative real-time polymerase chain reaction in 63 pairs of colorectal cancer tissues and paired adjacent non-tumor colorectal tissues. The relationship between ZEB1-AS1 expression and overall survival was analyzed by virtue of Kaplan-Meier analysis. Subsequently, small interfering RNA or lentivirus vector-mediated lncRNA ZEB1-AS1 was transfected into colorectal cancer cell lines. Cell viability and apoptosis were examined. Later, nude mouse transplantation experiment was conducted to evaluate the effect of ZEB1-AS1 on colorectal cancer development in vivo. It turns out that ZEB1-AS1 is upregulated in colorectal cancer tissues and its expression is significantly associated with overall survival rate and recurrence-free survival. Upregulation of ZEB1-AS1 colorectal cancer promotes cell proliferation and inhibits cell apoptosis. In addition, cell cycle inhibitory protein p15 participates in the oncogenic function of ZEB1-AS1. Collectively, ZEB1-AS1 has asignificant effect on colorectal cancer pathological process and serves as a valuable prognostic biomarker for colorectal cancer.

Synergistic cytotoxic effects of arsenite and tetrandrine in human breast cancer cell line MCF-7. Int J Oncol 2017; 51:587-598.

Abstract
To provide novel insight into the development of new therapeutic strategies to combat breast cancer using trivalent arsenic (AsIII)-based combination therapy, the cytotoxicity of a combination of AsIII and tetrandrine (Tetra), a Chinese plant-derived alkaloid, was investigated in the human breast cancer cell line MCF-7. Cytotoxicity was evaluated using cell viability, colony formation, wound healing, lactate dehydrogenase leakage and cell cycle assay. Alterations of genes associated with cell proliferation and death were analyzed using real-time PCR and western blotting. Intracellular arsenic accumulation (As[i]) was also determined. Tetra significantly enhanced the cytotoxicity of AsIII in MCF-7 cells in a synergistic manner. The combined treatment upregulated the expression level of FOXO3a, and subsequently resulted in a concomitant increase in the expression levels of p21, p27, and decrease of cycline D1, which occurred in parallel with G0/G1 phase arrest. Autophagy induction was also observed in the combination treatment. Importantly, combining AsIII with Tetra exhibited a synergistic inhibitory effect on the expression level of survivin. Furthermore, enhanced As[i] along with synergistic cytotoxicity was observed in MCF-7 cells treated with AsIII combined with Tetra or Ko134, an inhibitor of breast cancer resistance protein (BCRP), suggesting that Tetra or the BCRP inhibitor probably intervened in the occurrence of resistance to arsenic therapy by enhancing the As[i] via modulation of multidrug efflux transporters. These results may provide a rational molecular basis for the combination regimen of AsIII plus Tetra, facilitating the development of AsIII-based anticancer strategies and combination therapies for patients with solid tumors, especially breast cancer.
