Multiomics identifies tumor-intrinsic SREBP1 driving immune exclusion in hepatocellular carcinoma

KO versus WT tumor cells confirmed suppression of lipid biosynthesis genes.Our findings nominate an atlas of tumor-intrinsic drivers of immune exclusion, particularly SREBP1 via pro-tumorigenic macrophage (M2-like) reprogramming. These pathways may represent novel therapeutic targets to enhance antitumor immunity and deserve further study as targeted therapy candidates to enhance ICI in HCC.
