IFNA1 and neoplasm: Examination of formalin-fixed, paraffin-embedded (FFPE) tumor tissue from the resection showed an inverse correlation between tumor 2-HG and tumor-infiltrating CD3+ and CD8+ T cells (Fig. 2g), and again showed an association between 2-HG suppression and upregulation of antigen presentation and the IFN pathways (Extended Data Fig. 6).
