  sub:_4 prov:value "To confirm the correct transcription of these hormone receptors, we measured the levels of Fshr and Esr-2, mRNAs in the ovaries of TAF4b-null mice and their littermates by quantitative real-time rtPCR at several time points (Fig. 4B-E). We found that at 3 weeks of age, when we administer estrogen and PMSG, TAF4b-null mice displayed no significant reduction of either mRNA (Fig. 4B, D). In contrast, at 17 weeks of age, when TAF4b-null ovaries have only a few recognizable follicle structures, levels of both receptors are decreased compared to wild-type and heterozygous mice (Fig. 4C, E)." ;
