Abstract
The toxic reactive aldehyde lipid peroxidation byproduct 4-hydroxy-2-nonenal (HNE) is thought to be a major contributor to oxidant stress-mediated cell injury. HNE induced apoptosis in RAW 264.7 murine macrophage cells in a dose-dependent manner within 6-8 h after exposure. Expression of the antiapoptotic protein Bcl-2 in stably transfected RAW 264.7 cells prevented HNE-induced internucleosomal DNA fragmentation and apoptosis, and these cells resume growth after a temporary (24-48 h) growth delay. While parental RAW 264.7 cells released mitochondrial cytochrome c within 3 h after HNE exposure, expression of Bcl-2 prevented cytochrome c release. In control cells, p53 protein levels peaked at 6-9 h after HNE exposure and then declined, while in Bcl-2 expressing cells, p53 levels were maximal at 6-9 h and remained elevated up to 96 h. Expression of SV40 large T-antigen, which forms a stable complex with p53 protein, via stable transfection-blocked transactivation of the p53-regulated gene p21(WAF1/CIP1), but did not affect induction of apoptosis by HNE, suggesting that p53 function is not important in HNE-induced apoptosis. These results suggest that cytochrome c release, but not p53 accumulation, plays an essential role in HNE-induced apoptosis in RAW 264.7 cells.
