Correlation analysis showed that SATB2-AS1 expression was negatively correlated with IFN-γ (IFNG, r = − 0.20, p <  0.001)), CXCL9 (r = − 0.20, p <  0.001) and CXCL10 (r = − 0.19, p < 0.001) RNA levels in CRC tissues (Additional file 3: Figure S2e). This evidence concerns the gene IFNG and colorectal carcinoma.
