Abstract

Inactivation of the ten‑eleven translocation (TET) family members and catalyzation of 5‑methylcytosine (5‑mC) into 5‑hydroxymethylcytosine (5‑hmC) is associated with cancer initiation and progression. AMP‑activated protein kinase (AMPK) is an enzyme that stabilizes TET2; however, the clinical relevance of AMPK and TET2 expression levels is currently unclear. Therefore, the present study aimed to investigate the clinical implications of AMPK/TET2 expression levels in colorectal cancer (CRC). Immunohistochemistry was used to retrospectively examine the expression levels of AMPK and TET2 in paraffin‑embedded specimens obtained from 343 patients with CRC. The results demonstrated that AMPK and TET2 were highly expressed in CRC samples. No significant association was observed between the expression levels of TET2 and patient clinicopathological characteristics (age, tumor location, lymphatic, vascular and perineural invasion, Tumor‑Node‑Metastasis stages and differentiation); however, patients with low expression levels of TET2 more frequently presented with distant metastasis. By contrast, the expression levels of AMPK were significantly associated with lymph node and distant metastases. The survival analysis results revealed that high expression levels of TET2 were an independent predictor of favorable prognosis compared with low TET2 levels. However, no significant differences in overall survival were observed between patients with high and low expression levels of AMPK. These results described the clinical significance of AMPK/TET2 in CRC. The results of the multivariate analysis demonstrated that high expression levels of TET2 were a predictor of a favorable prognosis, whereas AMPK was not a significant factor for determining patient prognosis; therefore, further functional analysis of AMPK/TET2 expression in CRC is needed.
