We used two Sertoli-cell-specific Cre lines: Wt1-CreERT2 and Sox9-CreERT2, to induce Sox9 ablation on a Sox8 -/- background in the adult testis. Sox9/8 double KO testes undergo testis-to-ovary genetic reprogramming and Sertoli-to-granulosa cell transdifferentiation.

We induced specific deletion of miR-17-92 in Sertoli cells at the time of Amh expression in mouse embryos. We analyzed the effect of this deletion in the long term in adult testis. The transcriptome of mutant testis was consistently altered but do not produce a phenotype due to the testis homeostasi...

We also study the changes occurring in the testes of Mediterranean pine mice living in the wastelands during the breeding cycle. The transcriptomic analysis of active and regressed testis show that several molecular pathways that operate in Sertoli cells, involved in the control of spermatogenesis a...

Expression profiling of micro RNAs in mouse embryonic gonads before (11.5 days post coitum) and after (13.5 days post coitum) the critical period of sex determination

We investigated the miRNA cluster miR-106b~25 as potential candidate causing male infertility. We analized single and double KO mice. Single KO show derregulation of multiple molecular pathways and disrupted early spermatogenesys, but retain fertility. Double KO show severely disrupted testicular hi...
