Description_x000D_ Application_x000D_ JW74 has been used to modulate the level of β-catenin in chicken primordial germ cells (PGCs) in vitro._x000D_ JW74 may be used to study Wnt-mediated cell signaling in regulation of β-catenin._x000D_ Packaging_x000D_ 5, 25 mg in glass bottle_x000D_ Biochem/physiol Actions_x000D_ JW74 is a tankyrase inhibitor of β-catenin-mediated Wnt signaling activity. It degrades β-catenin by stabilizing axis inhibition protein (AXIN), a component of the β-catenin degradation complex. It reduces cell cycle progression and induces caspase-3 mediated cell apoptosis in osteosarcoma cells._x000D_ JW74 is an efficient and specific inhibitor of the canonical Wnt signaling in vitro and in vivo. It appears that JW74 affects the multiprotein complex consisting of b-catenin/GSK-3b/AXIN/APC /CK1 that controls the degradation of b-catenin. JW74 reduces growth of SW480 CRC cells in vitro by inhibiting cell-cycle progression at the G1/S phase. JW74 also inhibits tumor formation and growth in the small intestine and colon of ApcMin mice._x000D_ Features and Benefits_x000D_ This compound is also offered as part of Sigma′s Library of Pharmacologically Active Compounds (LOPAC®1280), a biologically annotated collection of high-quality, ready-to-screen compounds.
