RT-qPCR measurements of matched tumor and normal colon samples from 17 CRC patients (Figure 7—source data 1) suggested that the expression levels of the two Th17 cell markers IL-17 and RORC as well as miR-34a target IL-17rd were higher in tumor tissues than that in normal colon tissues, while miR-34a expression levels were downregulated (Figure 7C–F). This evidence concerns the gene IL17A and colorectal carcinoma.
