The present study aimed to explore FSH receptor binding inhibitor (FRBI) effects on the levels of c-Myc, K-Ras and VEGF related to ovarian cancer, to evaluate the mRNA and protein levels of FSHR in the cumulus-oocyte complex (COCs). COCs were cultured for 24 h in the in vitro maturation (IVM) media replenished with 0, 10, 20, 30 and 40 µg/mL FRBI. Contents of c-Myc, K-Ras, VEGF, cAMP and IP3 in IVM media were detected with ELISA kits, respectively. The results indicated that the levels of FSHR protein and mRNA were determined with Western blotting. C-Myc contents of four FRBI + FSH-treated groups (COM groups) were reduced after IVM of COCs. C-Myc concentrations of COM-3 group was lower than the FSH group (p < .05). K-Ras and IP3 contents of COM-4 were decreased as compared to FSH group (p < .05). Expression levels of FSHR mRNAs and proteins in COM-4 group were smaller than that of FSH group. This study revealed that FRBI treatment could decrease c-Myc and K-Ras levels in the IVM medium fluids, and depress the FSHR levels of COCs. Expression levels of FSHR mRNAs and proteins of COM-4 group were significantly decreased. FRBI exerted its action via the signal pathway of IP3 and cAMP.
