Detection of ITGA6 and ITGA6A in stool samples of controls and patients diagnosed with Ad and stage II-IV CRC by duplex qPCR. A: For total ITGA6, significant increases in copy number were observed for Ad and all tested CRC stages relative to Ctrl; B: ROC curve analysis of ITGA6 detection in Ad and in stages II-III CRC. AUC, sensitivity and specificity are provided (95%CI); C: For ITGA6A, significant increases in copy number were only observed for stage II and stage III CRC relative to Ctrl; D: Accordingly, ITGA6A/ITGA6 ratios were found to be significantly different between controls and stage II and III CRC. Results in A, C and D are expressed as median (interquartile range) of copy number relative to control patients. aP < 0.05, cP < 0.01, eP < 0.001 using the Kruskal-Wallis test followed by Dunn’s multiple comparison test.
