Purpose: This study was carried out to determine the consequences of the Rfx2-/- genotype on spermatogenesis in the mouse;	Methods: RNA was extracted from decapsulated testes of 21 day old mixed background mice of either genotype. Deep sequencing was used to determine quantitative expression of the genomes from independent replicates of each genotype;	Results: RNA-Seq analysis identified some 105 genes that are down regulated at least 2-fold in Rfx2-/- testes, with ~50 being reduced at least 10-fold;	Conclusion: Spermatogenesis undergoes complete arrest just prior to the end of the round spermatid period of sperm development in mutant mice. Sequencing results showed that approximately 105 genes were downregulated 2 fold or more in the testes of mutant mice. Comparison of similar studies of targeted mutations in genes for other transcription factor demonstrate that Rfx2 has a large and nearly unique set of genes that depend on it directly or indirectly. A large number of downregulated genes are identified with cilia function. SOURCE: Sylvain LEMEILLEREITH University of Geneva Medical School
