Modulatory effect of luteolin on redox homeostasis and inflammatory cytokines in a mouse model of liver cancer. - GreenMedInfo Summary

Liver cancer is one of the leading causes of cancer-associated mortality worldwide. Due to changes in lifestyle and daily exposure to various chemicals, which may lead to chemical intoxication, liver cancer has become a prominent disease in humans. Chemical-induced carcinogenesis in experimental animals has become a reliable model for the investigation of liver cancer-associated biological alterations that may mimic human hepatic cancer. Liver cancer in BALB/c mice was induced by administering diethylnitrosamine (DN) in drinking water for 6 weeks. Luteolin (LUT) is a flavone that is found in the leaves of the majority of spice-associated plants. In the present study, 20µg/kg of body weight LUT was administered intraperitoneally every alternate day to treat the DN-induced liver cancer in mice. LUT improved the host system by modifying the levels of α-fetoprotein, enzymatic antioxidants, such as superoxide dismutase and catalase, marker enzymes, such as AST and ALT, and lipid peroxides in the plasma or liver tissue. LUT also reduced the levels of glutathione and the inflammatory cytokines interleukin-2 and interferon-γ in the plasma or liver tissue. These findings augmented the treatment against liver cancer and supported the effective anticancer activity of LUT against DN-induced liver carcinogenesis in mice.
