DMRT1 is required at two steps of ovarian differentiation in rabbits.

DMRT1 is essential for two key steps of ovarian differentiation in rabbits, affecting somatic cell development and germ cell meiosis initiation.

• Why it matters: Understanding DMRT1's role in ovarian differentiation addresses gaps in knowledge about female fertility and its potential implications for human reproductive health.
• What they did: Using a DMRT1 mutant rabbit model, the study analyzed gonadal transcriptomes during early development and examined gene regulation related to meiosis, involving chromatin immunoprecipitation sequencing.
• The result: Disruption of DMRT1 led to altered gene expression in gonads, impaired germ cell meiosis, and suggests DMRT1's importance for female fertility, with potential relevance to human health.
