Biological Activity: RR-171 is an amino acid polypeptide and an inhibitor of the Wnt signaling pathway. RR-171 reduces the expression levels of Wnt-1, GSK3β and β-catenin. RR-171 induces apoptosis (Apoptosis) in pancreatic cancer cells, which is characterized by an increased Bax/Bcl-2 ratio, activation of Caspase-3/7/9, and increased Cleaved-PARP; this pro-apoptotic effect can be partially reversed by Z-VAD-FMK (HY-16658B). RR-171 also induces pyroptosis (Pyroptosis) in pancreatic cancer cells, which is manifested by activation of the NLRP-3 inflammasome, activation of Caspase-1, cleavage of GSDMD, upregulation of IL-1β and IL-18, and increased LDH release; this pro-pyroptotic effect can be partially reversed by VX-765 (HY-13205). RR-171 inhibits the viability, proliferation and colony formation of pancreatic cancer cells, with low cytotoxicity against normal cells. RR-171 downregulates the expression of Ki-67 and PCNA in tumor tissues in vivo, with favorable biosafety. RR-171 can be used in studies related to pancreatic cancer^[1].
