Lay Summary (English)

Lead
Lay summary
Our research effort is geared toward a better understanding of sex determination and gonadal function, by providing insights into the molecular and signaling pathways operating in the differentiating gonads but also during spermatogenesis or oogenesis. We are currently investigating the involvement of Dicer and microRNAs, a novel class of post-transcriptional regulators, in gonadal development as well as ovarian and testicular functions. So far, our results indicate that miRNAs are required for normal spermatogenesis both in the supporting and germ cell lineages. These exciting phenotypes are currently analyzed into more details. Overall, this study provides the first evidence that Dicer, and presumably microRNAs, is essential for spermatogenesis, and and may further our understanding of male infertility in humans.
