The mRNA expression of AHA1 was significantly increased in 32 CRC tissues compared to that in 32 paired normal colonic mucosa tissues from the GSE8671 datasets, as well as in 32 MSI CRC tissues, compared to that in 15 normal colonic mucosa tissues from the GSE24514 datasets (Fig. 1c). This evidence concerns the gene AHSA1 and colorectal carcinoma.
