Progastrin (PG) is processed into a number of smaller peptides including amidated gastrin (Gamide), non-amidated glycine-extended gastrin (Ggly) and the C-terminal flanking peptide (CTFP). Several groups have reported that PG, Gamide and Ggly are biologically active in vitro and in vivo, and are involved in the development of gastrointestinal cancers. CTFP is bioactive in vitro but little is known...
Progastrin is processed to a number of peptides including glycine-extended gastrin, amidated gastrin and the C-terminal flanking peptide (CTFP). Progastrin and gastrin-gly are pro-proliferative and anti-apoptotic in gastric and colorectal cancer cell lines. The CTFP is a major form of progastrin in the stomach and colon and stimulates proliferation. However the effect of CTFP on apoptosis has not...
