Abstract

Since the identification of cancer stem cells (CSCs) a new understanding of tumor occurrence and development has evolved. According to the stem cell (SC) theory, colorectal carcinoma (CRC) SCs may be derived from mutations in normal intestinal cells. CSCs can be defined by their cell of origin (SCs or early progenitor cells). Thus, through a shared stem cell marker between CSCs and SCs, it is possible to investigate the association between its expression and the various clinicopathological features in patients with CRC. Aldehyde dehydrogenase 1 (ALDH1) is an appropriate marker. The present study was performed to examine the role of ALDH1 in CRC. Through indirect fluorescence antibody staining, the association between ALDH1 protein expression and various clinicopathological parameters was investigated. Furthermore, enzyme‑linked immunosorbent assay (ELISA) was used to investigate the differing content of ALDH1 between CRC tissues and normal colorectal tissues. The results revealed that ALDH1 expression was markedly associated with tumor stage, Dukes' stage and the level of tumor cell differentiation. Using ELISA, it was demonstrated that there was a greater level of ALDH1 in CRC tissue than in normal colorectal tissue. Therefore, ALDH1 levels can be used as a useful parameter for pathological evaluation of tissue histology and to predict disease prognosis.
