Understanding Metabolic Pathway Rewiring by Oncogenic Gamma Herpesvirus

J Microbiol Biotechnol. 2024 Nov 28;34(11):2143-2152. doi: 10.4014/jmb.2407.07039. Epub 2024 Aug 30.

Abstract

Gamma herpesviruses, including Epstein-Barr virus (EBV) and Kaposi's sarcoma-associated herpesvirus (KSHV), are key contributors to the development of various cancers through their ability to manipulate host cellular pathways. This review explores the intricate ways these viruses rewire host metabolic pathways to sustain viral persistence and promote tumorigenesis. We look into how EBV and KSHV induce glycolytic reprogramming, alter mitochondrial function, and remodel nucleotide and amino acid metabolism, highlighting the crucial role of lipid metabolism in these oncogenic processes. By understanding these metabolic alterations, which confer proliferative and survival advantages to the virus-infected cells, we can identify potential therapeutic targets and develop innovative treatment strategies for gamma herpesvirus-associated malignancies. Ultimately, this review underscores the critical role of metabolic reprogramming in gamma herpesvirus oncogenesis and its implications for precision medicine in combating virus-driven cancers.

Keywords: EBV; KSHV; Metabolic reprogramming; metabolic therapeutics; oncogenic virus.
