Genome-wide analysis of gonadotropin-dependent gene expression and crosstalk of the regulatory pathways in the female ovaries

Effects of lack of functional LH receptor and/or a constitutively active FSH receptor on gene expression in the ovaries of female mice were studied. The results suggest that transgenic expression of the mouse Fshr in granulosa cells leads to abnormal ovarian structure/function and infertility. This finding indicates that gain-of-function mutations of the Fshr in female mice bring about distinct and clear changes in ovarian function. Total RNA was obtained from ovaries of 12 weeks old mice of different genotypes and extracted using Trizol followed by clean up with Qiagen RNeasy MinElute Cleanup Kit
