title: Berberine, a natural isoquinoline alkaloid, induces NAG-1 and ATF3 expression in human colorectal cancer cells.
abstract: Berberine is known to possess a wide variety of pharmacological activities, including pro-apoptotic activity. However, its molecular targets are not elucidated at present. NAG-1 and ATF3 are induced by several dietary compounds associated with pro-apoptotic activity. Berberine induces cell growth arrest, apoptosis, NAG-1, and ATF3 in human colorectal cancer cells. ATF3 induction by berberine is mediated in a p53-dependent manner, whereas NAG-1 induction by berberine is mediated by multiple signaling pathways. Our results suggest that berberine facilitates apoptosis and that NAG-1 and ATF3 expression plays an important role in berberine-induced apoptosis.
