High Expression of Bovine α Glutathione S-Transferase (GSTA1, GSTA2) Subunits Is Mainly Associated with Steroidogenically Active Cells and Regulated by Gonadotropins in Bovine Ovarian Follicles*

Abstract excerpt

We have previously shown that a major group of 28-30 kDa proteins decreases after the LH surge in bovine granulosa cells (GC). In the present study, we have characterized two proteins in this group in search of factors that may intervene in folliculogenesis and oocyte maturation. Polyclonal antibodies raised against 28 kDa or 29 kDa bovine GC proteins were used to screen a complementary DNA (cDNA) expression...
