Cc. Cheung et al., GALANIN - AN UNASSUMING NEUROPEPTIDE MOVES TO CENTER STAGE IN REPRODUCTION, Trends in endocrinology and metabolism, 7(8), 1996, pp. 301-306
Galanin is a neuropeptide widely distributed throughout the reproducti
ve system including the brain, pituitary, testes, ovaries, and accesso
ry reproductive tracts of both sexes. Within the hypothalamus, a subse
t of GnRH-producing neurons also synthesizes galanin. Galanin gene exp
ression in these GnRH neurons is highly inducible by estrogen. Galanin
is thought to play an important role in the generation of the preovul
atory LH surge, and may serve other functions yet to be discovered. (C
