WebThe results indicate that (a) the brain is a significant source of PGF2alpha, (b) the release of PGF2alpha from the brain occurs in pulses with a circhoral rhythm, and (c) the process through which estrogen exerts its negative and positive feedback effects on LH secretion may depend upon amplitude modulation of PGF2alpha output from the brain. WebData indicate a functional role for hypothalamic GRF in initiating GH pulses and the increase in GH secretion in underfed sheep was most probably due to a decrease in the release of SRIF into hypophysial portal blood. These studies characterized the secretion of GH-releasing factor (GRF) and somatostatin (SRIF) into the hypophysial portal circulation in …
