However, analysis of ITGA6A using specific probes revealed statistically significant expression in stools of patients with stage II and III CRC (Figure 1C) while ITGA6A/ITGA6 ratios suggest that ITGA6A consists of approximately half of the total ITGA6 copy number in the stools of patients with stage II and III CRC (Figure 1D). This evidence concerns the gene ITGA6 and colorectal carcinoma.
