AHSA1 and colorectal carcinoma: Results obtained from IHC staining of AHA1 in CRC and adjacent normal tissues from 20 CRC patients were consistent with the mRNA expression data, in which AHA1 expression was significantly increased in tumors (average score = 2.15) compared to that in adjacent normal tissues (average score = 1.35, p < 0.0001) (Fig. 1d).
