Project description:The maintenance of spermatogenesis in adult males is dependent on a population of mitotic germ cells with self-renewal potential known as undifferentiated spermatogonia. Regulation of undifferentiated spermatogonia function is dependent on transcriptional and post-transcriptional mechanisms. We have identified an essential role for the RNA helicase DDX5 in undifferentiated spermatogonia through generation of a UBC-CreERT2;Ddx5flox/flox mouse model that allows tamoxifen-dependent Ddx5 ablation. To identify genes regulated by DDX5, we generated lines of cultured undifferentiated spermatogonia from these mice and treated cells with tamoxifen (TMX) to induce Ddx5 knockout or vehicle (VEH) as a control, and performed RNA-sequencing analysis to compare these conditions.

ChIP-seq in wild type and Bmi1 knockdown undifferentiated spermatogonia

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 chromatin immunoprecipitation followed by massive parallel sequencing (ChIP-seq).

RNA-seq in wild type and Bmi1 knockdown undifferentiated spermatogonia

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.
