Project description:Totally 1,308 miRNAs were examined. Three miRNAs (hsa-miR-1976, 4728-3p, and 877-3p) were upregulated with fold change excess 0.8 and six miRNAs (hsa-miR-4497, -204-3p, -6126, -5787, -1273e, and -1908-3p) were downregulated in the exosome released from camptothecin-treated hepatoma. Comparing between results of these two samples revealed novel miRNA regulation upon anti-cancer drug treatments exosomal miRNAs from CPT-treated hepatoma and unrteated

Project description:We have sequenced miRNA libraries from human embryonic, neural and foetal mesenchymal stem cells. We report that the majority of miRNA genes encode mature isomers that vary in size by one or more bases at the 3’ and/or 5’ end of the miRNA. Northern blotting for individual miRNAs showed that the proportions of isomiRs expressed by a single miRNA gene often differ between cell and tissue types. IsomiRs were readily co-immunoprecipitated with Argonaute proteins in vivo and were active in luciferase assays, indicating that they are functional. Bioinformatics analysis predicts substantial differences in targeting between miRNAs with minor 5’ differences and in support of this we report that a 5’ isomiR-9-1 gained the ability to inhibit the expression of DNMT3B and NCAM2 but lost the ability to inhibit CDH1 in vitro. This result was confirmed by the use of isomiR-specific sponges. Our analysis of the miRGator database indicates that a small percentage of human miRNA genes express isomiRs as the dominant transcript in certain cell types and analysis of miRBase shows that 5’ isomiRs have replaced canonical miRNAs many times during evolution. This strongly indicates that isomiRs are of functional importance and have contributed to the evolution of miRNA genes

Project description:Baicalein, a purified flavonoid compound with defined chemical structure extracted from the dry roots of Scutellaria radix that is a broadly used herb in China, has been proved to possess significant anti-hepatoma activity by inhibiting cell proliferation, invasion, metastasis and inducing apoptosis, autophagy via several cancer-related signaling molecules. In recent years, emerging studies have demonstrated that Chinese medicinal herbs can exert their anti-tumor effects through targeting miRNAs，such as curcumin, camptothecin, resveratrol. However, there is still no related report about the effects of baicalein on miRNA expression profile when it exerts its inhibition on hepatoma tumor growth. To investigate whether the antitumor effect of baicalein is related to its modulation of miRNA expression in hepatocellular carcinoma (HCC), we profiled the miRNA expression in HCC cell line Bel-7402 treated with baicalein (0, 40, 80μM) for 24 hours using miRNA microarray and detected the changes by comparing the miRNA expression profile of HCC cell line Bel-7402 treated with baicalein (40 and 80 μM) and its DMSO control (0 μM). These findings suggest that modulation of miRNA expression may be an important mechanism underlying the anti-hepatoma effects of baicalein and lay the groundwork for further investigations.
