In cancer, recent studies disclosed that conditional whole‐body or hepatocyte‐specific knockout of Atg5 or Atg7 improved antitumor immunity by stimulating T cell‐mediated IFN‐γ, which led to an increase in MHC class I expression and antigen presentation of murine tumors with high mutational burden, through STING‐mediated immunity (Poillet‐Perez et al, 2020). This evidence concerns the gene STING1 and cancer.
