"The capsid protein of the West Nile virus (WNV) functions as an apoptotic agonist via the induction of mitochondrial dysfunction and the activation of caspases-9 and -3. Here, we have determined that the WNV capsid (WNVCp) is capable of binding to and sequestering HDM2 into the nucleolus," researchers in South Korea report. "WNVCp was shown to interfere with the formation of the HDM2 and p53 complex, thereby causing the stabilization of p53 and the subsequent induction of its target apoptotic protein, Bax. Whereas WNVCp was capable of inducing the p53-dependent apoptotic process in wild-type mouse embryonic fibroblasts (MEF) or SH-SY5Y cells, it exerted no significant...
