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.

摘要

已知黄连素具有多种药理活性,包括促凋亡活性。然而,其分子靶点目前尚未阐明。NAG-1和ATF3由几种与促凋亡活性相关的膳食化合物诱导产生。黄连素可诱导人结肠癌细胞的细胞生长停滞、凋亡、NAG-1和ATF3。黄连素对ATF3的诱导是以p53依赖的方式介导的,而黄连素对NAG-1的诱导是由多种信号通路介导的。我们的结果表明,黄连素促进凋亡,并且NAG-1和ATF3的表达在黄连素诱导的凋亡中起重要作用。
