Abstract
The pathogenesis of severe acute respiratory syndrome coronavirus (SARS CoV) is an important issue for treatment and prevention of SARS. Previously, SARS CoV 3C-like protease (3CLpro) has been demonstrated to induce apoptosis via the activation of caspase-3 and caspase-9 (Lin, C. W., Lin, K. H., Hsieh, T. H., Shiu, S. Y. et al., FEMS Immunol. Med. Microbiol. 2006, 46, 375-380). In this study, proteome analysis of the human promonocyte HL-CZ cells expressing SARS CoV 3CLpro was performed using 2-DE and nanoscale capillary LC/ESI quadrupole-TOF MS. Functional classification of identified up-regulated proteins indicated that protein metabolism and modification, particularly in the ubiquitin proteasome pathway, was the main biological process occurring in SARS CoV 3CLpro-expressing cells. Thirty-six percent of identified up-regulated proteins were located in the mitochondria, including apoptosis-inducing factor, ATP synthase beta chain and cytochrome c oxidase. Interestingly, heat shock cognate 71-kDa protein (HSP70), which antagonizes apoptosis-inducing factor was shown to down-regulate and had a 5.29-fold decrease. In addition, confocal image analysis has shown release of mitochondrial apoptogenic apoptosis-inducing factor and cytochrome c into the cytosol. Our results revealed that SARS CoV 3CLpro could be considered to induce mitochondrial-mediated apoptosis. The study provides system-level insights into the interaction of SARS CoV 3CLpro with host cells, which will be helpful in elucidating the molecular basis of SARS CoV pathogenesis.
