Description:
The role of gossypol in the cumulus expansion of oocyte-cumulus complexes (OCC) isolated from large antral porcine follicles was investigated. Marked suppression of cumulus expansion stimulated with follicle-stimulating hormone (FSH) and epidermal growth factor (EGF) was observed in the presence of different concentrations of gossypol. Comparable inhibitory effects were obtained in the presence of NO donor, S-nitroso-N-acetylpenicillamine or sodium nitroprusside, suggesting that the inhibitory effect of gossypol may be mediated via NO generation. The inhibitory effect of gossypol on cumulus expansion of OCC was accompanied by inhibition of progesterone secretion of OCC and the decrease of [125I]EGF binding to granulosa cells., J. Kolena, S.
