CXCL9 and gastric cancer: In gastric cancer specimens of immunotherapy patients, lncRNA RP11-1094M14.8 up-regulated the expression of CXCL9 by inhibiting miR-1269a, thereby promoting CXCL9-mediated lymphocyte infiltration into the lesion and inhibiting tumor growth (Zhang K. et al., 2020) (Figure 1).
