The present study aimed to unveil the gastroprotective potential of Vaccinium macrocarpon (VM) extract and its mechanism of action against indomethacin (INDO)-induced gastric ulcers in rats. To achieve this goal, rats were pretreated with either omeprazole (20 mg/kg) or VM (100 mg/kg) orally for 14 consecutive days. Gastric tissue samples were collected and various parameters were evaluated to understand the mechanism of VM's action, including the levels of superoxide dismutase, malondialdehyde, glutathione, CAT and transforming growth factor beta (TGF-β), as well as the mRNA expression levels of tumour necrosis factor alpha, interleukin 1 beta, nuclear factor kappa B (NF-κB) and inhibitor kappa B (IκB).
