Abstract

Reversible post-translational modification of serine and threonine residues by O‑linked N‑acetylglucosamine (O‑GlcNAc), termed O‑GlcNAcylation has been indicated to regulate the activities of a number of different proteins. Augmented O‑GlcNAcylation contributes to the etiologies of type 2 diabetes mellitus (T2DM) and cancer. Moreover, diabetic conditions increase the risk of colorectal cancer. However, the effect of O‑GlcNAcylation in patients with colorectal cancer and concurrent T2DM has not been elucidated. The current study evaluated the level of O‑GlcNAcylation in patients with colorectal cancer with or without T2DM. Notably, O‑GlcNAcylation levels were significantly higher in tissues from patients with T2DM compared with those in patients without T2DM, and higher in cancer tissues compared with corresponding adjacent tissues. O‑GlcNAcylation and cancer stage were more strongly correlated in cancer tissues from patients with T2DM compared with those from patients without T2DM. Additionally, distant metastasis was significantly correlated with O‑GlcNAcylation in cancer tissues from patients with T2DM. β‑catenin levels in colorectal cancer tissues were the highest in patients with advanced‑stage cancer and concurrent T2DM. In SW480 human colon cancer cells, thiamet G (TMG) treatment and OGA silencing, which increased O‑GlcNAcylation, significantly increased β‑catenin and SNAIL in high‑glucose, but not during normal‑glucose conditions. These data suggest that O‑GlcNAcylation is closely associated with distant metastasis, most likely through upregulation of the β‑catenin/SNAIL signaling pathway in colorectal cancer patients with T2DM.
