Abstract:
:A microbial secondary metabolite, arisostatins A (As-A), was originally discovered as a substance carrying the antibiotic activity against Gram-positive bacteria and shown to possess potent anti-tumor properties. The mechanism by which arisostatins A initiates apoptosis remains poorly understood. In the present report we investigated the effect of arisostatins A on activation of the apoptotic pathway in HN-4 cells. Arisostatins A was shown to be responsible for the inhibition of HN-4 cell growth by inducing apoptosis. Treatment with 4 microM arisostatins A for 24h produced morphological features of apoptosis and DNA fragmentation in HN-4 cells. Arisostatins A caused dose-dependent apoptosis and DNA fragmentation of HN-4 cells used as a model. Treatment with caspase inhibitor significantly reduced the arisostatins A-induced caspase 3 activation. In addition, arisostatins A-induced apoptosis was associated with the generation of reactive oxygen species (ROS), which was prevented by an antioxidant NAC (N-acetyl-cysteine). These data indicate that cytotoxic effect of arisostatins A on HN-4 cells is attributable to the induced apoptosis and that arisostatins A-induced apoptosis is mediated by caspase-3 activation pathway, loss of mitochondrial transmembrane potential (DeltaPsi(m)), and release of cytochrome c into cytosol.
