SMYD3 Promotes Immune Evasion in Clear Cell Renal Cell Carcinoma via SREBP1‐Mediated Transactivation of CD47

Advanced Science, EarlyView.
Cancer cell‐intrinsic SMYD3 orchestrates an immunosuppressive microenvironment and impairs the response to PD‐1 blockade by reprogramming immune cells landscape in the tumor microenvironment of clear cell renal cell carcinoma (ccRCC). The immunomodulatory function of SMYD3 is mediated via the SREBP1/CD47 pathway.
