Does estradiol potentiate ghrelin-stimulated pulsatile growth hormone secretion in postmenopausal women?
Estrogen augments ghrelin's near-physiological stimulation of pulsatile GH secretion and mimics ghrelin's acceleration of initial GH release. Thus, we hypothesize that estrogen and a GH secretagogue act via independent as well as convergent mechanisms.
The transcriptional and translational levels of leptin, leptin receptor, and STAT3 were higher in hemorrhagic BAVM, suggesting that leptin may play an important role in the hemorrhagic mechanism of BAVM.
