Outline of Final Research Achievements

In the course of embryonic development, he polycomb group (PcG) proteins are major chromatin components that are involved in the regulation of target genes. Mice lacking the function of the PcG protein Cbx2 show defects in gonadal, adrenal, and splenic development. In particular, XY Cbx2 KO mice develop ovaries but not testes, and the gonads are hypoplastic in both sexes. How Cbx2 regulates target genes in development of these tissues remains largely unknown. In this project, we tried to identify the target region of Cbx2 in embryonic gonad, and further delete the region by CRISPR-Cas9 genome editing in mice, to analyze the molecular mechanisms of Cbx2 in developing gonad.
