Thyrotropin Releasing Hormone Stimulation of Prolactin Release

Thyrotropin releasing hormone (TRH) and high extracellular K+ induce prolactin release from rat pituitary cells (GH3 cells) in culture. TRH, as well as high K' (SO m), was shown to increase 46Ca2' efflux from these cells. The effects of TRH and high K' on membrane polarization was determined indirectly using the lipophilic cation, triphenylmethyl… CONTINUE READING
