IL17A and colorectal carcinoma: We observed positive correlations between the expression of YKL-40, IL-17A, PD-L1, and MMP-8 (Figure 1) in GEO dataset GDS4382, containing 34 CRC tumors and adjacent non-cancerous tissues (Figure 1A–C,F), and in GEO dataset GDS4515, with 49 CRC microsatellite instable tumors and normal colonic mucosa samples (Figure 1D,E).
