re·leas·ing fac·tors (RF),

1. any substance, usually of hypothalamic origin, capable of accelerating the rate of secretion of a given hormone by the anterior pituitary gland;
2. factors required in the termination phase of either RNA biosynthesis or protein biosynthesis. Synonym(s): termination factor
3. colloquial shortened form for the HMG-CoA reductase inhibitors used as antihyperlipidemic agents, whose generic names end with the suffix statin. Synonym(s): statins
Synonym(s): liberins, releasing hormone

releasing hormone

Abbreviation: RH
Any of a group of substances secreted by the hypothalamus that control or inhibit the release of various hormones. They include thyrotropin-releasing hormone, gonadotropin-releasing hormone, dopamine, growth hormone-releasing hormone, corticotropin-releasing hormone, and somatostatin. Dopamine and somatostatin act to inhibit release of the hormones they act upon.

While investigating some of these synthetic drugs that stimulate the release of growth hormone, researchers discovered that several don't work through the brain's well-known triggering agent, which is called growth hormone releasing hormone. Instead, scientists learned that the drugs act upon a previously unrecognized cell-surface protein, or receptor, in the brain's pituitary and hypothalamus.
