Abstract

Women who carry the FMR1 premutation may suffer from ongoing deterioration of ovarian function. The lucidity of the molecular mechanism of FXTAS is emerging and findings from research in the field of FXTAS could elucidate the pathogenesis of FXPOI. To date there are three possible mechanisms for ovarian dysfunction in FMR1 permutation carriers. The first is the RNA toxic gain-of-function mechanism initiating loss of function of over 30 specific RNA-binding proteins. The second is associated to the formation of an abnormal polyglycine-containing protein (FMRpolyG), and the third is related to novel lncRNAs, named FMR4 and FMR6. Herein we describe our laboratory methodology, focusing on the culturing and manipulation of granulosa cells from human female premutation carriers, trying to reveal the actual possible mechanisms liable to FXPOI. Detecting the precise pathways in premutation carrier might facilitate in offering these women the opportunity to make an informed decision regarding their reproductive and family planning.
