Oncogenic viral infection and amino acid metabolism in cancer progression: Molecular insights and clinical implications

Na Liu et al. Biochim Biophys Acta Rev Cancer. 2022 May.

Abstract

Viruses lack essential living system, so they must hijack host cell metabolism for its survival and reproduction. Interestingly, the metabolic reprogramming induced by oncovirus is critical for the malignant transformation. Amino acid can supply the source of nitrogen and carbon for biosynthesis or fulfill the energy requirement for the rapid growth of tumor cells. Amino acid metabolism caused by oncogenic viral infection often mirrors metabolic changes observed in cancer cells, such as glutamine addiction, asparagine dependence, arginine auxotrophy and active serine/ proline metabolism. In this review, we describe amino acid metabolism reprogramming in tumors. We also discuss how oncogenic viruses hijack amino acid metabolism in the stress status. Further research on the metabolic profile of virus-related cancers will not only provide new targets for tumor prevention and treatment, but novel diagnostic and therapeutic strategies as well.

Keywords: Amino acid metabolism; Infection-related carcinogenesis; Metabolic reprogramming; Oncogenic virus.
