Abstract

The main aim of the present study was to measure hypoxia-inducible factor‑1α (HIF‑1α) in serum and colonic mucosa of ulcerative colitis (UC) patients and to analyze its role in the pathogenesis, disease activity and severity of UC. A total of 47 UC patients and 13 UC in remission patients were recruited for the present study. Ten healthy subjects were also included to serve as controls. HIF‑1α in the serum was measured using ELISA. The citrate‑microwave‑SP immunohistochemical method was used to measure the expression of HIF‑1α in colonic mucosa. The results showed that, HIF‑1α in serum was notably higher in UC patients (73.21±28.65) than UC in remission patients (44.54±14.75) and controls (42.83±15.49). The difference between UC patients and UC in remission patients was significant (P<0.05). A correlation analysis revealed that, the HIF‑1α level in serum was positively associated with disease activity, disease severity and endoscopic grade. The expression of HIF‑1α in colonic mucosa of UC patients was (58.05±13.83) higher than that in UC in remission patients (3.00±2.72) and controls (3.04±2.69) and this difference was statistically significant (P<0.05). A positive correlation was identified between the expression of HIF‑1α in colonic mucosa and the disease activity, severity and endoscopic grade. Thus, the present findings indicated that, HIF‑1α is likely to play an important role in the pathogenesis of UC and may serve as a biomarker to evaluate disease activity and severity in UC patients.
