Project description:Mammalian spermatogenesis is regulated by epigenetic mechanisms that maintain cell type-specific transcriptional programs. The epigenetic regulator BMI1, a PRC1 member, is required for maintaining undifferentiated spermatogonia, but the underlying mechanisms remain unclear. To address this issue, here we performed RNA-sequencing (RNA-seq) analysis in both wild type and Bmi1 knockdown spermatogonia populations.

Project description:Purpose: Study of the role of BMI1 dependent and indpendent of PRC1 in castration-resistant prostate cancer(CRPC) Method: The expression of BMI1 or RING1B was silenced by 2 independent siRNA strands targeted at BMI1 or RING1B in C4-2 cells, scramble RNA as control. mRNA profiles and genome-wide chromatin-state maps were generated by deep sequencing. AR, BMI1 and IgG ChIP was conducted in C4-2 cells. Results: AR-induced genes were significantly down regulated by BMI1 knockdown but not RING1B. higher expression levels of BMI1 activated genes (those downregulated by BMI1 knockdown) were significantly associated with poorer disease-free and poorer overall survival.

Project description:Bmi1 is a component of the Polycomb-repressive complexes (PRC) and essential for maintaining the pool of adult stem cells. PRC are key regulators for embryonic development by modifying chromatin architecture and maintaining gene repression. To assess the role of Bmi1 in pluripotent stem cells and upon exit from pluripotency during differentiation, we studied forced Bmi1 expression in mouse embryonic stem cells (ESC). We found that ESC do not express detectable levels of Bmi1 RNA and protein and that forced Bmi1 expression had no obvious influence on ESC self-renewal. However, upon ESC differentiation Bmi1 effectively enhanced development of hematopoietic cells. Global transcriptional profiling identified a large array of genes that were differentially regulated during ESC differentiation by Bmi1. Importantly, we found that Bmi1 induced a prominent up-regulation of Gata2, a zinc finger transcription factor, which is essential for primitive hematopoietic cell generation from mesoderm. In addition, Bmi1 caused sustained growth and a more than 100-fold expansion of ESC-derived hematopoietic stem/progenitor cells within 2-3 weeks of culture. The enhanced proliferative capacity was associated with reduced Ink4a/Arf expression in Bmi1-transduced cells. Taken together, our experiments demonstrate distinct activities of Bmi1 in ESC and ESC-derived hematopoietic progenitor cells. In addition, Bmi1 enhances the propensity of ESC in differentiating towards the hematopoietic lineage. Thus, Bmi1 could be a candidate gene for engineered adult stem cell derivation from ESC.

Project description:We have found the existence of a Bmi1+ population in the adult heart contributing to the organ low-rate turnover and repair with the generation of new cardiomyocytes. We show that the Bmi1+ population is a sub-population of the cardiac Sca-1+ progenitor cells. We have analyzed the gene profile by deep-sequencing (RNA-Seq) of Bmi1+ and Sca-1+Bmi1- cells in homeostatic heart condition. On the other hand, we have compared gene profile by deep-sequencing (RNA-Seq) of Bmi1+ cells in homeostatic condition versus Bmi1+ cells 5 days after myocardial infarction (MI). Analysis of RNA-Seq data revealed a differential expression signature between both subsets of cardiac stem/progenitors cells in homeostatic condition and also differences between Bmi1+ cells after AMI versus homeostatic condition.
