WebbHowever, activin is not produced in these follicles, suggesting that either the receptors are inactive at this stage or they are used by another protein. Co-localization of activin and inhibin subunits, receptors, and Smads only occurs in granulosa and theca cells of small antral, aromatase-positive follicles as well as granulosa cells of early atretic follicles. WebbAktivin je proteinski dimer, sastavljen od dvije identične ili vrlo slične beta podjedinice. Inhibin je također dimer u kojem je prva komponenta beta podjedinice slična ili identična beta podjedinici u aktivinu. Međutim, za razliku od aktivina, druga komponenta dimera inhibina je alfa podjedinica koja je u većoj mjeri različita. WebbIn these cells, activin-A stimulated follistatin and inhibin/activin βB mRNA levels but had no effect on βA. Together, DEX and activin-A caused a further increase in follistatin mRNA levels while T attenuated the effect of activin-A alone. Both steroids attenuated the effect of activin-A on βB mRNA accumulation. bob weir tickets the chicago theatre march 11

"WebbActivin and inhibin are two closely related protein complexes that have almost directly opposite biological effects. Activins, members of the TGF-beta superfamily, are disulfide-linked dimeric proteins originally purified from gonadal fluids as proteins that stimulated pituitary follicle stimulating hormone (FSH) release.
