    On July 23 , the international academic journal PLOS Pathogens published online a research paper from the Shanghai Institute of Pasteur Institute of Chinese Academy of Sciences Zhong Jin's research paper: Glycometabolism regulates hepatitis C virus release


     

     

    Hepatitis C virus ( hepatitisCvirus , HCV ) is a positive-stranded RNA virus that can cause chronic hepatitis, cirrhosis and liver cancer


    However, due to the existence of metabolic reprogramming, tumor cells and normal somatic cells have significant differences in a series of metabolic pathways such as sugar metabolism


    Many previous studies have found that if the sugar source in the culture medium is changed from glucose to galactose, it can force tumor cells cultured in vitro to weaken glycolysis and switch to oxidative phosphorylation as the main energy supply method


    In this work, the researchers found that culturing Huh7 cells in a medium that uses galactose as a sugar source can significantly inhibit the release of HCV virus particles, but does not affect HCV cell entry, replication, assembly and maturation


    The study also found that the direct transmission of HCV between cells is not affected by host cell sugar metabolism.
