Webb1 feb. 2024 · Overproduction of uroguanylin or guanylin leads to acute diarrhea, which is typically found in bacterial infections when Staphylococcal enterotoxins (STs) bind to the GUCY2C receptor (Currie et al. 1992, Forte & Currie 1995). Moreover, the pharmacological industry has created synthetic agonists of UGN that also bind to the GUCY2C receptor. WebbMaritoclax, an active constituent isolated from marine bacteria, has been known to induce Mcl-1 downregulation through proteasomal degradation.
