Fig. 4. KrasG12D downregulates genes essential for granulosa
cell differentiation and ovulation. (A) qRT-PCR of
ovulation-related genes from mouse whole ovary mRNAs. Six ovaries from
different animals were analyzed. (B) KrasG12D
downregulated the expression of Fshr and prevented the FSH-induced
expression of Lhcgr in cultured granulosa cells. Expression of
KrasG12D was induced by infecting the cells with an
adenoviral vector encoding Cre recombinase (Ad-Cre). FSH (100 ng/ml) was added
to the medium of cells infected, or not, with Ad-Cre. NT, non-treated.
Ppib was amplified by RT-PCR in the same samples, as loading
control.
