Enzastaurin-induced accumulation of β-catenin triggers UPR-mediated growth arrest and c-Jun-mediated apoptosis. Enzastaurin inhibits phosphorylation of β-catenin, thereby inducing accumulation of β-catenin leading to ER stress response-mediated growth arrest, as well as triggering apoptosis via c-Jun-stabilized p73.
