RAGE antagonist peptide TFA is an advanced glycation end products (RAGE) antagonist. RAGE antagonist peptide TFA prevents RAGE from binding with several of its most important ligands, including HMGB-1, S100P, and S100A4. RAGE antagonist peptide TFA possesses anti-tumor and anti-inflammatory activities[1][2].
RAGE antagonist peptide TFA (RAP) reduces the ability of the ligands to stimulate RAGE activation of NFκB in cancer cells in vitro[1].
RAGE antagonist peptide TFA (RAP, 100 µg) inhibits RAGE-mediated Basal NFκB Activity in PDAC cells in vivo[1].RAGE antagonist peptide TFA (RAP) reduces the growth and metastasis of pancreatic tumors and also inhibited glioma tumor growth[1].In mice bearing asthma, RAGE antagonist peptide TFA (RAP; 4 mg/kg; i.p.) blunts airway reactivity, airway inflammation and goblet cell metaplasia, and decreases release of Th2 cytokines. RAGE antagonist peptide TFA also reduces total, cytoplasmic and nuclear levels of β-catenin, enhances β-catenin phosphorylation at Ser33/37/Thr41, which triggers ubiquitination, down-regulated expression of β-catenin targeted genes, and tends to keep β-catenin at the cytomembrane, shifting β-catenin from a signalling active pattern to an adhesive function[2].
