A potential role of Baicalin to inhibit apoptosis and protect against acute liver and kidney injury in rat preeclampsia model

•Baicalin largely alleviated the symptoms of systolic and diastolic pressures and reduced urine protein.•Baicalin protected against liver and kidney cells apoptosis.•Baicalin effected the apoptotic proteins expression of liver and kidney tissue in JEG-3 cells and rat preeclampsia model. The incidence of acute liver and kidney injury in pregnancy is companied by Preeclampsia (PE), which has remained a major cause of maternal and fetal morbidity, and mortality. Therefore, a significant treatment to protect against liver and kidney injury of PE requires new drugs to develop potential therapeutic benefits to the clinic. Baicalin played protection role on inhibition of cell apoptosis which is a potential drug for keep liver and kidney from acute injury on PE patients. In this study, we made PE rat disease model with liver and kidney acute injury, and then used low-, medium-, and high-dose of Baicalin to treat PE rat, respectively. We found that Baicalin attenuated acute injury symptoms and inhibited apoptosis of rat liver and kidney tissues. The intervention of Baicalin increased the expression of anti-apoptotic protein XIAP and Bcl-2, reduced the expression of apoptotic protein Caspase-9 in rat liver; and similarly, Baicalin increased the expression of Bcl-2, while inhibited Caspase-9 and AT1 in rat kidney. Interestingly, Baicalin intervention with medium dose showed a better function for inhibiting apoptosis. Our data suggests that Baicalin is a potentially therapeutic candidate for preventing liver and kidney damage, which shed a light on therapeutic benefit for PE rat models.
