β-cateninpeptide,(βCATp) is a naturally occurring self-peptide presented by Kb that very efficiently mediates positive selection of the OT-I thymocytes.
Selective peptide-based β-catenin Degrader. Comprises a β-catenin-targeted stapled peptide, xStAx, linked to a VHL-binding peptide. Reduces β-catenin levels in HEK293T cells and colorectal cancer cell lines. Selectively degrades β-catenin over other Wnt signaling pathway components. Inhibits tumor growth in APCmin + mice, with constitutively active Wnt signaling, and reduces survival of patient-derived colorectal cancer cell organoids.
Foxy-5 is a peptide that mimics the WNT5A protein and is expected to reduce the mobility of the cancer cells. Foxy-5 triggers cytosolic free calcium signaling without affecting β-catenin activation and it impairs the migration and invasion of epithelial c
