Effect of the peptide PHI-27 on prolactin release in vitro
Abstract:
The present study demonstrates that PHI, a peptide belonging to the glucagon-secretin group and thus structurally similar to VIP, can release prolactin from dispersed rat anterior pituitary cells and also causes release of prolactin from hemipituitaries. PHI-like immunoreactivity has previously been demonstrated in a hypothalamic system with nerve endings in the median eminence, and, taken together, these findings suggest that PHI may represent a physiologic prolactin-releasing factor.
