Isolinderalactone Resistance to the Liver Injury Induced by Oxaliplatin in Rats Through Inhibiting IL-6/STAT3 Signal Pathway

Oxaliplatin (OXA) is easy to cause sinusoidal obstruction syndrome (SOS), leading to liver injury. Isolinderalactone (ILL), one of the main components of Lindera aggregate, has been reported to have a protecting effect on the liver. However, it is unclear whether ILL has a therapeutic effect on liver injury caused by OXA. This study aims to determine the effect of ILL on the prevention and treatment of OXA-induced liver injury and to provide a basis for the chemotherapy of gastrointestinal tumors.Intraperitoneal injection of folinic acid, 5-fluorouracil, and OXA was administered on the SOS rat model for 7 weeks. The indexes of liver function were measured by biochemical kit. The ratio of liver weight to body weight was calculated. The pathological analysis of the liver was scored with the SOS scoring standard, fibrosis was evaluated with a four-point scale. The expression of inflammation factors was detected by Real-Time PCR, and the related indexes of IL-6/STAT3 were examined by Western blot analysis.ILL down-regulated the portal vein pressure and alleviated the abnormal liver function of SOS rats and improved the liver lesions. ILL inhibited the SOS by inhibiting IL-6/STAT3.ILL resistance to liver injury through inhibiting IL-6/STAT3 signal pathway.
