Anti-cancer activity of hesperidin against hepatocellular carcinoma-induced in rats through upregulation of RIPK1 expression.

Background: Receptor-interacting protein kinase-1 (RIPK1) is an important protein in hepatocellular carcinoma (HCC) pathogenesis. Hesperidin (Hes) is a natural product found in citrus species and is believed to have an anti-cancer effect. Aims: This research was planned to elucidate the protective influence of Hes on the RIPK1 pathway in thioacetamide (TAA)-induced HCC. Materials and methods: HCC was induced in male Sprague Dawley rats using TAA and Hes was administered orally. Liver function tests, oxidative stress status, and antioxidant markers were evaluated. Histopathological examination of hepatic tissues was carried out by staining with hematoxylin and eosin stains. The protein level of RIPK1 was quantified by ELISA. Results: Hes exerted a hepatoprotective effect by significantly improving liver functions and oxidative stress status. This was supported by the integrity preservation of the liver tissues, which was indicated by histopathological examination. Moreover, Hes significantly increased the hepatic RIPK1 protein level. Conclusion: These results reveal that, Hes protected against HCC by decreasing oxidative stress and upregulation of RIPK1 protein level. [ABSTRACT FROM AUTHOR]
