Cytoskeleton reorganization mediates alpha6beta1 integrin-associated actions of laminin on proliferation and survival, but not on steroidogenesis of ovine granulosa cells Animal Physiology
Le Bellego, F.; Fabre, S.; Pisselet, C.; Monniaux, D..
Background Laminin (LN) is one of the most abundant extracellular matrix components of the basal lamina and granulosa cell layers of ovarian follicles. Culture of ovine granulosa cells (GC) on LN substratum induces cell spreading, enhances cell survival and proliferation, and promotes luteinization. Previous investigations have shown that these effects are mostly mediated by the alpha6beta1 integrin, but its signalization pathways have not been investigated. This study aimed to assess the importance of the cytoskeleton in the alpha6beta1 integrin-mediated actions of laminin on survival, proliferation and steroidogenesis of ovine GC. Methods The relationships between morphology and functions of ovine GC cultured on substrata containing LN or/and...

Regulation of ovarian folliculogenesis by IGF and BMP system in domestic animals Animal Physiology
Monget, P.; Fabre, S.; Mulsant, P.; Lecerf, F.; Elsen, J.M.; Mazebourg, S.; Pisselet, C.; Monniaux, D..
Involvement of Insulin-like Growth Factors (IGFs) and IGF-Binding Proteins (IGFBPs) in ovarian folliculogenesis has been extensively studied during the last decade. In all mammalian species, IGF-I stimulates granulosa cell proliferation and steroidogenesis. The concentrations of IGF-I and IGF-II do not vary during terminal follicular growth and atresia. In contrast, the levels of IGFBP-2 and IGFBP-4, as well as IGFBP-5 in ruminants, dramatically decrease and increase during terminal follicular growth and atresia, respectively. These changes are responsible for an increase and a decrease in IGF bioavailability during follicular growth and atresia, respectively. They are partly explained by changes in ovarian expression. In particular, expression of IGFBP-2...
