Project description:We report the application of chromatin immunoprecipitation coupled with high-throughput sequencing (ChIP-seq) for high-throughput profiling of H3K27me3 modifications in sk-hep-1(sk), sk-hep-1-shEZH2 (sks) and LO2 cells. Following standard ChIP procedure, 10 ng of each DNA sample was used for Illumina sequencing. Statistically significant ChIP-enriched regions (peaks) were identified by sk vs sks (p-value threshold of 10-2) or sk vs LO2 (p-value threshold of 10-3). Enriched peaks were annotated by the nearest gene using the newest UCSC RefSeq database. We identify genes modified by EZH2-mediated H3K27me3. This study provides insights into these down stream genes modified by EZH2 regulated H3K27me3 in HCC cell lines.
Project description:To explore the m6a modification in SK-Hep-1 cells, we performed RNA immunoprecipitation with an antibody against m6a (SYSY), and sequencing was performed using Illumina NovaSeq 6000
Project description:The incidence of TP53 loss-of-function in hepatocellular carcinoma is very high. In order to clarify the gene expression differences induced by the changes of TP53 gene, we used two human hepatocellular carcinoma cell lines, SK-HEP-1 and Hep 3B with TP53 knockdown or overexpression for RNA sequencing . SK-HEP-1 is a TP53 wild-type hepatocellular carcinoma cell line. Thus, we knockdown TP53 in SK-HEP-1. Hep 3B is a TP53 loss-of-function hepatocellular carcinoma cell line. Thus, we overexpress TP53 in Hep 3B. Results of RNA-seq analysis showed the differences after knocking-down or overexpressing TP53.
