Gonadotropin and kisspeptin gene expression, but not GnRH, are impaired in cFOS deficient mice. [PDF]

open access: yes, 2015
cFOS is a pleiotropic transcription factor, which binds to the AP1 site in the promoter of target genes. In the pituitary gonadotropes, cFOS mediates induction of FSHβ and GnRH receptor genes.

Variants of human chorionic gonadotropin from pregnant women and tumor patients recognized by monoclonal antibodies [PDF]

open access: yes, 1993
In biological fluids, hCG and its free alpha- (hCG alpha) and beta-subunits (hCG beta), occur in multiple forms. These various forms differ at the molecular level primarily in glycosylation, but also differ in protein backbone modifications corresponding
