GO-203 TFA
Based on 2 publication(s) in Google Scholar
GO-203 TFA is a potent MUC1-C oncoprotein inhibitor. GO-203 TFA is an all D-amino acid peptide that consists of a poly-R transduction domain linked to a CQCRRKN motif that binds to the MUC1-C cytoplasmic tail and blocks MUC1-C homodimerization. GO-203 TFA downregulates TIGAR (TP53-induced glycolysis and apoptosis regulator) protein synthesis by inhibiting the PI3K-AKT-S6K1 pathway. GO-203 TFA induces the production of ROS and loss of mitochondrial transmembrane potential. GO-203 TFA inhibits the growth of colon cancer cells in vitro and as xenografts in nude mice.

GO-203 (5 μM; for three days) TFA inhibits MUC1 positive colorectal cancer cell proliferation by decreasing intracellular GSH levels and enhanced ROS production. GO-203 TFA has no effect on cell growth on MUC1-negative SW480 and LOVO cells[2].
GO-203 (5 μM; for three days) TFA induces approximately 80% death of SKCO-1 cells. GO-203 TFA results in a significant decrease in mitochondrial membrane potential[2].
GO-203 (5 μM; for three days) TFA inhibits AKT-mTORC-S6K1 translation pathway in colorectal cancer cells[2].
GO-203 (5 μM; for three days) TFA significantly decreases GSH levels in SKCO-1 cells[2].
