Description

In Vitro

RAGE antagonist peptide (RAP) reduces the ability of the ligands to stimulate RAGE activation of NFκB in cancer cells in vitro^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

RAGE antagonist peptide (RAP, 100 μg) inhibits RAGE-mediated Basal NFκB Activity in PDAC cells in vivo^[1].
RAGE antagonist peptide (RAP) reduces the growth and metastasis of pancreatic tumors and also inhibited glioma tumor growth^[1].
In mice bearing asthma, RAGE antagonist peptide (RAP; 4 mg/kg; i.p.) blunts airway reactivity, airway inflammation and goblet cell metaplasia, and decreases release of Th2 cytokines. RAGE antagonist peptide also reduces total, cytoplasmic and nuclear levels of β-catenin, enhanced 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].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:	Cancer cells expressing the NFκB-luc reporter implanted into immune-deficient mice^[1].
Dosage:	100 µg.
Administration:	Intratumoral delivery (or intraperitoneally).
Result:	Systemic administration caused a substantial reduction (p<0.05) in the NFκB signal 5 h after injection.
