Tan IIA also induced ER stress and apoptosis in human breast cancer BT-20 cells by increasing caspase-12, DNA damage-inducible gene 153 (GADD153), caspase-3, p-JNK, phospho-p38 mitogen-activated protein kinases (p-p38), and Bcl-2-Associated X protein (Bax) levels with decreased expression of B-cell lymphoma extra large (Bcl-xl) and p-ERK in a time- and dose-dependent manner (Yan et al., 2012). The gene discussed is CASP3; the disease is breast cancer.
