Project description:WIPI2 regulates the growth of human liver cancer cells. We used microarray to detail the global program of gene expression underlying the cell growth of human liver cancer cell line Hep3b cells.
Project description:In this study, we investigated the biological roles and potential mechanisms of pentamethylquercetin (PMQ), a natural polymethyl flavones, against Hep3B liver cancer cells. Cell viability and growth curves were determined using the cell counting kit-8 (CCK-8) assay; flow cytometry was used to detect cell cycle and apoptosis; colony formation assay and JC-1 staining were used to detect cell proliferation and mitochondrial membrane potential changes, respectively. Transcriptome sequencing and western blotting were respectively used to investigate transcription and expression changes in Hep3B cells treated with PMQ. Treatment with 30 and 100 μM PMQ more significantly inhibited cell growth and proliferation in Hep3B cells than in HepG2 and LO2 cells. PMQ induced Hep3B cell cycle arrest and apoptosis by significantly reducing CDK4, CDK6, Cyclin D1, Cyclin E1, Cyclin B1 and Bcl-2 expression and increasing Bax, CDK1 and cleaved PARP levels. Transcriptomic profiles and western blotting results revealed that the MAPK and TNF signaling pathways may be involved in PMQ-induced Hep3B apoptosis.
Project description:In order to find a new genes regulated by SMARCA4, RNA was extracted 2days after transfection of si-SMARCA4 into a Hep3B cell line. We hypothesized that when SMARCA4 was inhibited, the genes expression will be suppressed.
Project description:Overexpression of SOX4 in various kinds of cancers specimen was associated with poor prognosis of patients; however, the role of SOX4 in angiogenesis or tumor microenvironment modulation remains unclear. Therefore the endogenous SOX4 was knockout and the differential gene expression between Hep3B and Hep3B SOX4-/- cells were examined via genechip. We found that the differentially expressed genes, EzH2, a SOX4-associated partner, and CXCL12, were repressed in Hep3B SOX4-/- cells compared with parental Hep3B; these results were further assessed via qRT-PCR in Hep3B SOX4-/- versus Hep3B cells.
