In this study we employed a novel bioluminescence resonance energy transfer (BRET) biosensor to study the coupling specificity of somatostatin receptor 5 (SST5) and its naturally occurring mutant R240W in living cells. Our previous data demonstrated that SST5 carrying the R240W mutation as well as other mutations in the third intracellular loop maintained the ability to inhibit intracellular cAMP levels similarly to the wild-type but failed to mediate the inhibition of intrace...

Primary ovarian insufficiency (POI) is a critical fertility defect characterized by a progressive and silent impairment of the follicular reserve. POI aetiology is heterogeneous and largely unknown, but a maternal inheritance often characterizes idiopathic forms. Therefore, we hypothesized a possible involvement of a mitochondrial defect in the pathogenesis of this disease since mitochondrial biogenesis and bioenergetics play an essential role in ovarian folliculogenesis. Our ...
