Project description:To investigated how BMI1 inhibitor (PTC) affected the function of primary T cells, we treated Tcells with PTC. We then performed gene expression profiling analysis using data obtained from RNA-seq of peritoneal macrophages with PTC 209.
Project description:m6A-binding RNAs were analyzed by imprinting RNA-sequencing of anti-m6A antibody-retrieved complexes from primary T cells. We then performed gene expression profiling analysis using data obtained from RIP-seq of primary T cells treated with PTC
Project description:Bmi1 plays a pivotal role in hepatic carcinoma (HCC), but its targets in HCC is unknown. To screen the potential targets, we transfected HCC cell line Huh7 and Hep3B with Bmi1 shRNA lenti-virus. After confirming the Bmi1 was knocked down using western blotting, we extracted total RNA and then run the microarray detection. Gene expression profiles in Bmi1 KO cells were compared with those in Bmi1 WT cells to screen potential targets of Bmi1.
Project description:Identification of BMI1, RYBP and H2AK119UB interactome in Glioblastoma (GBM) to elucidate BMI1 roles independent of the PRC1-complex in GBM.
Project description:Polycomb group (PcG) proteins including EZH2, SUZ12 ,BMI1,CBX8 and so on, which specifically catalyze trimethylation of histone 3 lysine 27 (H3K27me3), and methylated H3K27 can be recognized by other specific binding proteins to compress chromatin structure, leading to the transcriptional repression of the target genes. To explore a potential functional implication of PcG components in HCC, we stably transfected HepG2 cells with either vectors or constructs expressing shRNA that specifically targets EZH2, SUZ12, BMI1, or CBX8. A cDNA microarray analysis was performed on shRNA KDs of EZH2, SUZ12, BMI1, or CBX8 HepG2 cells. To obtain a broader understanding of the molecular network of PcG in HCC, the whole genome microarray expression profiling was performed on shRNA KDs of EZH2, SUZ12, BMI1, or CBX8 HepG2 cells. Comparison of gene expression results from shRNA KDs of EZH2, SUZ12, BMI1 or CBX8 HepG2 cells.

Project description:A mouse model of HCC has been developed based on the reported inactivation of the RB pathway in the majority of human HCC. This mouse model harbors floxed alleles of Rb and p130 genes, as well as germline mutation of the p107 gene. Various strategies to activate the activity of a Cre recombinase leads to the efficient deletion of the three genes in the liver of adult mice (TKO mice). Disruption of the RB pathway induces the rapid development of HCC. These HCCs share many similar features of human HCC. The goal of this array is to assess genome wide expression of TKO HCCs. Gene expression of control livers (n=4) or TKO HCCs (n=5) was measured using the Affymetrix GeneChip Mouse Genome 430-2.0 arrays
