18829546 Koehler JA, Harper W, Barnard M, Yusta B, Drucker DJ: Glucagon-like peptide-2 does not modify the growth or survival of murine or human intestinal tumor cells. Cancer Res. 2008 Oct 1;68(19):7897-904.

Glucagon-like peptide-2 (GLP-2) secreted from enteroendocrine cells exerts proabsorptive, regenerative, and cytoprotective actions in the normal and injured gut epithelium.
However, GLP-2 did not stimulate cell growth or attenuate cycloheximide-, LY294002-, indomethacin-, or chemotherapy-induced cytotoxicity in vitro.

Cycloheximide also showed no effect, suggesting that glucagon-induced AQP8 expression does not depend on protein synthesis but rather on protein degradation.
Glucagon stimulates the vesicle trafficking of aquaporin-8 (AQP8) water channels to the rat hepatocyte canalicular membranes, a process thought to be relevant to glucagon-induced bile secretion.

Cycloheximide and in vivo labelling experiments attributed IR downregulation to enhanced degradation.

J Endocrinol. 2009 Jul;202(1):65-75. Epub 2009 Apr 27.

Additionally, the cycloheximide chase study demonstrated that EX-4 significantly accelerated iNOS protein degradation.
Meanwhile, glucagon-like peptide-1 (GLP-1) and its potent analog exendin-4 (EX-4) were well known for beta-cell proliferation.

16644694 Koehler JA, Drucker DJ: Activation of glucagon-like peptide-1 receptor signaling does not modify the growth or apoptosis of human pancreatic cancer cells. Diabetes. 2006 May;55(5):1369-79.

Glucagon-like peptide (GLP)-1 promotes beta-cell proliferation and survival through stimulation of its specific G-protein-coupled receptor; however, the potential for GLP-1 receptor (GLP-1R) agonists to promote growth and proliferation of human pancreatic-derived cells remains poorly understood.
Ex-4 did not modulate the proliferation of these cell lines in vitro and did not inhibit apoptosis after exposure of cells to cytotoxic agents such as cycloheximide, indomethacin, LY294002, or cyclopamine.

Then, nicastrin has a central role in presenilin-mediated processing of beta-amyloid precursor protein and in some aspects of Notch/glp-1 signaling in vivo.
