Abstract:
In the context of the present study, we have aimed to examine the effects of the administration of whey protein through rectal enema to a acetic acid-induced ulcerative colitis in rats on the pathways of nuclear-related factor-2 (Nrf-2), heme oxygenase-1 (HO-1), nuclear factor kappa B (NF-κB), active protein kinase-1 (AP-1), tumour necrotising factor-alpha (TNF-α), and cyclooxygenase-2 (COX-2), IL-6, IL-10. Material and methods 28 rats were employed for the trial. Ulcerative colitis was induced through the use of acetic acid. The therapeutic doses of whey protein were administered rectally. Ulcerative colitis was made subject to histopathological examination and protein levels in colon tissue measured with the Western Blot Method. Results The significant increases observed in the levels of AP-1, COX-2, IL-6, IL-10, NF-κβ, and TNF-α as markers of inflammation following the development of ulcerative colitis enjoyed remarkable decreases along with the administration of whey protein (p 〈 0.05). On the other hand, we identified a decrease in the Nrf2-ARE signal pathway and HO-1 protein assuming protective roles on the colon inflammatory response along with the development of ulcerative colitis and an activation of the Nrf2-HO-1 pathway by the whey protein. Conclusions Whey protein modulates Nrf2/HO-1 and NF-kB pathways, thereby creating a therapeutic effect against colonic inflammation induced by acetic acid (AA) by reason of its anti-inflammatory implications.
