In adrenocortical cells the trophic hormone ACTH induces expression of TIMP-1 and the increase in TIMP expression is also associated with decreased collagenase activity.

The trophic hormones increase CYP11A1 gene expression through transcription factors such as steroidogenic factor 1 ( SF-1 ), by the ? isoform of activating protein 2 ( AP-2 ) in the human, and many others.

Hormones secreted by the anterior pituitary are trophic hormones ( Greek : trophe, nourishment ) and tropic hormones . " Trophic hormones " directly affect growth either as hyperplasia or hypertrophy on the tissue it is stimulating . " Tropic hormones " are named for their ability to act directly on target tissues or other endocrine glands to release hormones, causing numerous cascading physiological responses.

The results suggest that trophic hormones ( e . g ., leutenizing hormone, adrenocorticotropic hormone ) stimulate these steroid producing cells to make 5-( " S " )-HETE and 5-( " S " ) HpEPE which in turn increase the synthesis of steroidogenic acute regulatory protein; the latter protein promotes the rate-limiting step in steroidogenesis, transfer of cholesterol from the outer to the inner membrane of mitochondria and thereby acts in conjunction with trophic hormone-induce activation of protein kinase A to make progesterone and testosterone.
