C-type natriuretic peptide (CNP) acts via its specific membrane-bound guanylyl cyclase receptor, GC-B, to stimulate cGMP production. Stimulation of cGMP impinges upon PKG and PKA signalling, leading to cell proliferation and cell cycle events. In endothelial cells, CNP is thought to perform a predominantly anti-mitogenic role, but the role of CNP on cell proliferation, cell cycle and DNA synthesis in pituitary cell lines has yet to be established. Using the mouse gonadotroph-d...
