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.

Project description:Identifying a Baicalein-related Prognostic signature Contributes to prognosis prediction and Tumor Microenvironment of Pancreatic Cancer
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:Effects of baicalein in C. elegans gene expression is studied, as our results indicate a lifespan extension effect produced by this molecule. Microarrays were used to detail the global programme of gene expression underlying the lifespan extension and identified distinct classes of up/down-regulated genes in animals treated with baicalein.
Project description:Pancreatic cancer is one of the deadliest cancers in humans and is yet refractory to immunotherapy. Identifying factors that can sensitize pancreatic cancer to immune cells may thus hold the key to improving immunotherapy efficacy. Herein, by pooled CRISPR activation screening, we find that the transcriptional regulator Mcrs1 (Microspherule protein 1) is pivotal to the immune sensitivity of pancreatic cancer cells, with elevated Mcrs1 expression inducing enhanced immune responses and tumor suppression in mice.
