Gene expression of mouse embryonic gonad

ABSTRACT: To elucidate the function of NANOS2 to regulate the transcriptome in embryonic male germ cells, we performed expression microarray analysis of the embyornic gonads of the Nanos2+/-, Nanos2-/- male and wild type female from E12.5 to E15.5. The Nanos2+/- and Nanos2-/- female gonads at E15.5 were analyzed as a negative control. Biological duplicates were examined at each stage, genotype, and sex for each experiment.

Testicular development in the mouse is triggered in somatic cells by the function of Sry followed by the activation of fibroblast growth factor 9 (FGF9), which regulates testicular differentiation in both somatic and germ cells. However, the mechanism is unknown. We show here that the nodal/activin signaling pathway is activated in both male germ cells and somatic cells. Disruption of nodal/activin signaling drives male germ cells into meiosis and causes ectopic initiation of female-specific gen  ...[more]
