Analysis of correlation of the expression of IL-17RA with CSC markers in 68 CRC samples revealed that IL-17RA expression positively correlated with the expression of stem cell markers CD133 (p = 0.0006), LGR5 (p < 0.0001) and ALDH1 (p = 0.0002), and stemness genes SOX2 (p = 0.002) and c-MYC (p < 0.0001) (Figure 1B-F). This evidence concerns the gene ALDH1A1 and colorectal carcinoma.
