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. To investigate whether the antitumor effect of baicalein is related to its modulation of lncRNA 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 lncRNA expression profile of HCC cell line Bel-7402 treated with baicalein (40 and 80 μM) and its DMSO control (0 μM).

Project description:We sought to find out the molecular mechanism of CENPK displayed in hepatocellular carcinoma. Microarray experiments were carried out to identify different gene expression between CENPK-knockdown BEL-7404 cell line and Scramble BEL-7404 cell lines.
Project description:We treated Bel-7402 and Bel-7404 cells with corosolic acid, and then used TMT to analyze protein expression in both cell lines after treatment with corosolic acid
Project description:To further analyze the change of microRNA (miRNA) between TRAIL-sensitive and TRAIL-resistant Bel-7402 cells Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL)
Project description:We performed proteomics isobaric tags for relative and absolute quantification (iTraq) to identify proteins that changed before and after NMT1 was knocked down in both Bel-7402 and Bel-7404 cells.
Project description:Baicalein is a bioactive compound that is found in an herbal plant, Oroxylum indicum, grown in Southeast Asia including Thailand. There are several reports investigating on the bioactivities of baicalein including an anticancer activity. However, there is no report on the anticancer activity of the baicalein in nasopharyngeal carcinoma. Thus, the aim of this study is to identify differentially expressed genes (DEGs) that are targets of baicalein in order to reveal cellular pathways and molecular mechanisms of the baicalein in nasopharyngeal carcinoma. In this study, NPC HK-1 cells were used as an NPC representative and treated with 10 and 20 µM baicalein for 24 hours before collecting cells for whole transcriptome profiles. The results revealed that a number of cellular pathways, based on KEGG enrichment analysis, are affected baicalein treatment such as focal adhesion and PI3K-Akt signaling pathway which were also phenotypically related to cell migration and invasion assays. Changes in transcriptome profiles of baicalein-treated HK-1 cells would provide insight on baicalein activity in NPC.
Project description:LncRNA profiling of hepatocellular carcinoma vs. matched noncancerous liver tissue, aimed to analyze the lncRNA expression profile of hepatocellular carcinoma (HCC) and identify prognosis-related lncRNAs.
