Abstract
AIMS Angelol-A (Ang-A), a kind of coumarins, is isolated from the roots of Angelica pubescens f. biserrata. However, AA exerts antitumor effects and molecular mechanism on cervical cancer cells is unknown. MAIN METHODS Cell viability was determined using the MTT assay, and the cell cycle phase was assessed by PI staining with flow cytometry. Ang-A-treated cells with/without Antago-miR-29a-3p (miR-29a-3p inhibitor) or U0126 (MEK inhibitor) were assessed for the expression of miR-29a-3p, in vitro migration/invasion, and angiogenesis using qRT-PCR, a chemotaxis assay, and tube formation assay, respectively. The expression of mitogen-activated protein kinases/MMP2/MMP9/VEGFA was determined by western blot analysis with applicable antibodies. KEY FINDINGS Ang-A significantly inhibited MMP2 and VEGFA expression, cell migration, and invasive motility in human cervical cancer cells. Conditioned medium inhibited tube formation in HUVECs. Ang-A principally inhibited invasive motility and angiogenesis by upregulating the expression of miR-29a-3p that targets the VEGFA-3' UTR. The role of miR-29a-3p was confirmed using Antago-miR-29a-3p, which reversed the Ang-A-inhibited expression of MMP2 and VEGFA, invasive motility, and angiogenesis in human cervical cancer cells. The ERK pathway was implicated in mediating the metastatic and angiogenic action of Ang-A. Combined treatment with Ang-A treated and U0126 exerted a synergistic inhibitory effect on the expression of MMP2 and VEGFA and the metastatic and angiogenic properties of human cervical cancer cells. SIGNIFICANCE These findings are the first to indicate that in human cervical cancer cells, Ang-A exerts anti-metastatic and anti-angiogenic effects via targeting the miR-29a-3p/MMP2/VEGFA axis, mediated through the ERK pathway.

Abstract
The molecular mechanisms underlying the antineoplastic properties of metformin combined with nelfinavir remain elusive. To explore this question, transmission electron microscopy (TEM) was used to observe the combinatorial effect of inducing autophagosome formation in human cervical cancer cells. Western blotting respectively assayed protein expression of LC3I, LC3II, Beclin-1, Autophagy-related protein 7 (Atg7), Autophagy-related protein 3 (Atg3), NAD-dependent deacetylase sirtuin-3 (SIRT3) and major histocompatibility complex class I chain-related gene A (MICA). Lactate dehydrogenase (LDH) cytotoxicity assay evaluated natural killer (NK) cell cytotoxicity in the presence of metformin and nelfinavir in combination or each drug alone. Using tumor xenografts in a nude mouse model, antitumor efficacy of the drug combination was assessed. We found that the drug combination could induce autophagosome formation in human cervical cancer cells. The biomarker proteins of autophagy, including Beclin-1, Atg7 and Atg3, decreased, but the ratios of LC3I/II increased. We also found that this drug combination sensitizes human cervical cancer cells to NK cell-mediated lysis by increasing the protein of SIRT3 and MICA. Moreover, this drug combination markedly induced autophagy of SiHa xenografts in nude mice. Therefore, it can be concluded that metformin, in combination with nelfinavir, can induce SIRT3/mROS-dependent autophagy and sensitize NK cell-mediated lysis in human cervical cancer cells and cervical cancer cell xenografts in nude mice. Thus, our findings have revealed the detailed molecular mechanisms underlying the antitumor effects of metformin in combination with nelfinavir in cervical cancer.

Abstract
The fruit of the white mulberry tree (Morus alba L.) is a multiple fruit with a sweet flavor commonly consumed around the world. Chemical investigation of the fruits led to the isolation of two indole acetic acid derivatives (1 -2) including a new compound, which turned out to be an isolation artifact, 3S-(β-D-glucopyranosyloxy)-2,3-dihydro-2-oxo-1H-indole-3-acetic acid butyl ester (1), along with five known compounds (3 -7). Compounds 2 and 7 were newly identified from mulberry fruit. The new isolation artifact (1) exhibited cytotoxic effect on human cervical cancer Hela cells in a dose-dependent manner. Compound 1 activated caspase-8, caspase-9, and caspase-3, followed by cleavage of PARP, a substrate of caspase-3, in a dose-dependent manner. Simultaneous alterations in protein expression of mitochondrial factors Bax, BID and Bcl-2 were also observed. A comparison between compounds 1 and 2 led to a structure-activity relationship analysis of the cytotoxic effect. These results suggest that compound 1 could be beneficial in human cervical cancer treatment, and provide a theoretical basis for further application of compound 1.

Abstract
PURPOSE Previously, it has been reported that microRNA-145 (miR-145) is lowly expressed in human cervical cancers and that its putative tumour suppressive role may be attributed to epithelial-mesenchymal transition (EMT) regulation. Here, we aimed to assess whether miR-145 may affect EMT-associated markers/genes and suppress cervical cancer growth and motility, and to provide a mechanistic basis for these phenomena. METHODS The identification of the SMAD-interacting protein 1 (SIP1) mRNA as putative miR-145 target was investigated using a 3' untranslated region (3'UTR) luciferase assay and Western blotting, respectively. The functional effects of exogenous miR-145 expression, miR-145 suppression or siRNA-mediated SIP1 expression down-regulation in cervical cancer-derived C33A and SiHa cells were analysed using Western blotting, BrdU incorporation (proliferation), transwell migration and invasion assays. In addition, the expression levels of miR-145 and SIP1 were determined in primary human cervical cancer and non-cancer tissue samples using qRT-PCR. RESULTS We found that miR-145 binds to the wild-type 3'UTR of SIP1, but not to its mutant counterpart, and that, through this binding, miR-145 can effectively down-regulate SIP1 expression. In addition, we found that exogenous miR-145 expression or siRNA-mediated down-regulation of SIP1 expression attenuates the proliferation, migration and invasion of C33A and SiHa cells and alters the expression of the EMT-associated markers CDH1, VIM and SNAI1, whereas inhibition of endogenous miR-145 expression elicited the opposite effects. The expression of miR-145 in cervical cancer tissue samples was found to be low, while that of SIP1 was found to be high compared to non-cancerous cervical tissues. An inverse expression correlation between the two was substantiated through the anlaysis of data deposited in the TCGA database. CONCLUSION Our data indicate that low miR-145 expression levels in conjunction with elevated SIP1 expression levels may contribute to cervical cancer development. MiR-145-mediated regulation of SIP1 provides a novel mechanistic basis for its tumour suppressive mode of action in human cervical cancer cells.

Abstract
High mobility group box 1 (HMGB1) is a ubiquitous nuclear protein known to be highly expressed in human cervical (CaCx) and colorectal (CRC) cancers, and sustained high levels of HMGB1 contribute to tumourigenesis and metastasis. HMGB1-targeted cancer therapy is of recent interest, and there are not many studies on miRNA-mediated HMGB1 regulation in these cancers. Since miRNA-based therapeutics for cancer is gaining importance in recent years, it was of interest to predict miRNAs targeting HMGB1. Based on the identification of a potential miR-34a response element in HMGB1-3' untranslated region (3'UTR) and an inverse correlation between HMGB1 and miR-34a expression levels in CaCx and CRC tissues, from a subset of the local population as well as a large sampling from TCGA database, experiments were performed to validate HMGB1 as a direct target of miR-34a in CaCx and CRC cells. Ectopic expression of miR-34a decreased the wild-type HMGB1-3'UTR luciferase activity but not that of its mutant in 3'UTR luciferase assays. While forced expression of miR-34a in CaCx and CRC cells inhibited HMGB1 mRNA and protein levels, proliferation, migration and invasion, inhibition of endogenous miR-34a enhanced these tumourigenic properties. siRNA-mediated HMGB1 suppression imitated miR-34a expression in reducing proliferation and metastasis-related events. Combined with the disparity in expression of miR-34a and HMGB1 in clinical specimens, the current findings would help in not only understanding the complexity of miRNA-target regulatory mechanisms but also in designing novel therapeutic interventions in CaCx and CRC.

Abstract
OBJECTIVE To examine the cytotoxic properties of both the kenaf (Hibiscus cannabinus L.) seed extract and kenaf seed oil on human cervical cancer, human breast cancer, human colon cancer and human lung cancer cell lines. METHODS The in vitro cytotoxic activity of the kenaf (Hibiscus cannabinus L.) seed extract and kenaf seed oil on human cancer cell lines was evaluated by using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide and sulforhodamine B assays. Cell morphological changes were observed by using an inverted light microscope. RESULTS The kenaf seed extract (KSE) exhibited a lower IC50 than kenaf seed oil (KSO) in all of the cancer cell lines. Morphological alterations in the cell lines after KSE and KSO treatment were observed. KSE and KSO possessed effective cytotoxic activities against all the cell lines been selected. CONCLUSIONS KSE and KSO could be potential sources of natural anti-cancer agents. Further investigations on using kenaf seeds for anti-proliferative properties are warranted.
