Genome-wide analysis of YAP and TFCP2 binding DNA in liver cancer cells

ABSTRACT: To seek additional evidence that YAP closely interacts with TFCP2, we performed ChIP-seq assays in Bel-7402 cells using anti-TFCP2 or anti-YAP antibodies. We found that a subset of YAP binding regions overlapped with the TFCP2-occupied sites, suggesting that YAP- and TFCP2-regulated transcriptional outputs are likely correlated.

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 lncRNAs，such as curcumin, camptothecin, resveratrol，paclitaxel. However, there is still no related report about the effects of baicalein on lncRNA 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 lncRNA expression in hepatocellular carcinoma (HCC), we profiled the lncRNA expression in HCC cell line Bel-7402 treated with baicalein (0, 40, 80μM) for 24 hours using lncRNA microarray and detected the changes by comparing the lncRNA 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 lncRNA expression may be an important mechanism underlying the anti-hepatoma effects of baicalein and lay the groundwork for further investigations.
