Project description:Research has shown that Taf4b-deficient female mice display excessive perinatal germ cell death, delayed germ cell cyst breakdown, and increased chromosome asynapsis. Therefore, we hypothesized that TAF4b, as part of TFIID, regulates oogenesis and meiotic gene programs. However, the transcriptomic effects of Taf4b-deficiency and how this may lead to the infertility we observe in mice has not yet been studied. Therefore, we performed RNA-seq to examine gene expression changes in E16.5 female Taf4b-heterozygous and Taf4b-deficient germ cells

Project description:Taf4b-deficient male mice are initially sub-fertile and become infertile due to a depletion of the spermatogonial stem cell (SSC) reserve. During embryonic time points, significantly reduced numbers of germ cells have been observed in the Taf4b-deficient male gonad and previous research has shown that Taf4b mRNA expression peaks at E15.5. Therefore, we hypothesized that TAF4b, as part of TFIID, regulates cell cycle and SSC gene programs. We performed RNA-seq to examine gene expression changes in E14.5 and E16.5 male Taf4b-wildtype, Taf4b-heterozygous, and Taf4b-deficient germ cells
