2Apoptosis and the target genes of microRNA-21显示文摘MicroRNA-21(miR-21) is frequently up-regulated in cancer and the majority of its reported targets are tumor suppressors.Through functional suppression,miR-21 is implicated in practically every walk of oncogenic life:the promotion of cell proliferation,invasion and metastasis,genome instability and mutation,inflammation,replicative immortalization,abnormal metabolism,angiogenesis,and evading apoptosis,immune destruction,and growth suppressors.In particular,miR-21 is strongly involved in apoptosis.In this article,we reviewed the experimentally validated targets of miR-21 and found that two thirds are linked to intrinsic and/or extrinsic pathways of cellular apoptosis.This suggests that miR-21 is an oncogene which plays a key role in resisting programmed cell death in cancer cells and that targeting apoptosis is a viable therapeutic option against cancers expressing miR-21.Lindsey E.Becker Buscaglia 2011Chinese Journal of Cancer2011,30,6:49

5miR-125b Confers Resistance of Ovarian Cancer Cells to Cisplatin by Targeting Pro-apoptotic Bcl-2 Antagonist Killer 1显示文摘Chemotherapy is the preferred therapeutic approach for advanced ovarian cancer,but a successful long-term treatment is prevented by the development of drug resistance.Recent works have underlined the involvement of non-coding RNAs,microRNAs(miRNAs) in cancer development,with several conjectures regarding their possible involvement in the evolution of drug resistance.This study is to investigate the promoting effects and mechanism of miR-125b involved in the development of chemoresistance in ovarian cancer.The different expression of miR-125b in cisplatin-sensitive ovarian cancer cell line(OV2008) and its resistant variant(C13*) was identified by real-time PCR.An in vitro cytotoxicity assay and apoptosis assay using CCK-8 assay and flow cytometry,were carried out to detect the effect of miR-125b and Bak1 on cisplatin resistance of cells.Real-time PCR,Western blotting and luciferase reporter assay were used to detect whether Bak1 is a target of miR-125b.As compared with OV2008 cells,the expression levels of miR-125b in C13* cells were increased.It was found that the up-regulation of microRNA-125b caused a marked inhibition of cisplatin-induced cytotoxicity and apoptosis and a subsequent increase in the resistance to cisplatin in OV2008 and C13* cells.Moreover,Bak1 was a direct target of miR-125b,and down-regulation of Bak1 suppressed cisplatin-induced apoptosis and led to an increased resistance to cisplatin.Our study indicates that miR-125b has a significantly promoting effect on chemoresistance of C13* cells and up-regulation of miR-125b expression contributes to cisplatin resistance through suppression of Bak1 expression.This finding has important implications in the development of targeted therapeutics for overcoming cisplatin resistance in ovarian cancer.孔繁飞 孙朝阳 王中显 韩凌斐 翁丹卉 卢运萍 陈刚 2011Journal of Huazhong University of Science and Technology(Medical Sciences)2011,31,4:19

14miR-200 family expression is downregulated upon neoplastic progression of Barrett's esophagus显示文摘AIM: To investigate miR-200 family expression in Barrett's epithelium, gastric and duodenal epithelia, and esophageal adenocarcinoma. METHODS: Real-time reverse transcriptase-polymerase chain reaction was used to measure miR-200, ZEB1 and ZEB2 expression. Ingenuity Pathway Analysis of miR-200 targets was used to predict biological outcomes. RESULTS: Barrett's epithelium expressed lower levels of miR-141 and miR-200c than did gastric and duodenal epithelia (P < 0.001). In silico analysis indicated roles for the miR-200 family in molecular pathways that distinguish Barrett's epithelium from gastric and duodenalepithelia, and which control apoptosis and proliferation. All miR-200 members were downregulated in adenocarcinoma (P < 0.02), and miR-200c expression was also downregulated in non-invasive epithelium adjacent to adenocarcinoma (P < 0.02). The expression of all miR-200 members was lower in Barrett's epithelium derived high-grade dysplastic cell lines than in a cell line derived from benign Barrett's epithelium. We observed signif icant inverse correlations between miR-200 family expression and ZEB1 and ZEB2 expression in Barrett's epithelium and esophageal adenocarcinoma (P < 0.05). CONCLUSION: miR-200 expression might contribute to the anti-apoptotic and proliferative phenotype of Barrett's epithelium and regulate key neoplastic processes in this epithelium.Cameron M Smith David I Watson Mary P Leong George C Mayne Michael Z Michael Bas PL Wijnhoven Damian J Hussey 2011World Journal of Gastroenterology2011,17,8:13
15Silicon photonic platforms for mid-infrared applications [Invited]显示文摘Silicon photonic integrated circuits for telecommunication and data centers have been well studied in the past decade, and now most related efforts have been progressing toward commercialization. Scaling up the silicon-oninsulator(SOI)-based device dimensions in order to extend the operation wavelength to the short mid-infrared(MIR) range(2–4 μm) is attracting research interest, owing to the host of potential applications in lab-on-chip sensors, free space communications, and much more. Other material systems and technology platforms, including silicon-on-silicon nitride, germanium-on-silicon, germanium-on-SOI, germanium-on-silicon nitride, sapphireon-silicon, Si Ge alloy-on-silicon, and aluminum nitride-on-insulator are explored as well in order to realize low-loss waveguide devices for different MIR wavelengths. In this paper, we will comprehensively review silicon photonics for MIR applications, with regard to the state-of-the-art achievements from various device demonstrations in different material platforms by various groups. We will then introduce in detail of our institute's research and development efforts on the MIR photonic platforms as one case study. Meanwhile, we will discuss the integration schemes along with remaining challenges in devices(e.g., light source) and integration. A few application-oriented examples will be examined to illustrate the issues needing a critical solution toward the final production path(e.g., gas sensors). Finally, we will provide our assessment of the outlook of potential futureresearch topics and engineering challenges along with opportunities.TING HU BOWEI DONG XIANSHU LUO TSUNG-YANG LIOW JUNFENG SONG CHENGKUO LEE GUO-QIANG LO 2017Photonics Research2017,5,5:13
