Ulcerative colitis (UC) is a chronic gastrointestinal disorder interfering with life quality. A total of 60 male Wistar rats were divided into four equal groups: Control (group I), hesperidin only (group II), UC untreated (group III), and UC treated with hesperidin (group IV). Hesperidin had modulatory effects on UC pathogenesis, which might be through alleviating colonic sphingosine phosphate phosphatase 2 messenger RNA expression and sphingosine kinase-1 levels, thus suppressing the subsequent downstream inflammatory and apoptotic cascades represented by decreased macrophage inflammatory protein-1α and enhancement of B-cell lymphoma 2 immunohistochemistry expression. Also, it improved mitochondrial biogenesis by increasing the peroxisome proliferator-activated receptor-gamma-coactivator 1-α level. It successfully restored redox potential as evidenced by marked alleviations of the nitric oxide and peroxynitrite levels, increasing total antioxidant capacity, and activating the superoxide dismutase enzyme. Also, hesperidin alleviated the UC disease activity index and improved the histopathological picture. These findings may offer a new therapeutic strategy for UC treatment.
