ADARB1 and neoplasm: In this study, TISIDB database was used to analyze the correlation between ADARB1 and immune system, and the results showed that ADARB1 had most significant correlation with several tumor-infiltrating lymphocytes (NK cells, Tcm, Tem, and eosinophils), immunomodulators (KDR, CSF1R, CD160 and TGFBR1), and chemokines (CXCL12, CCL14, CXCL14 and CCL21).
