We investigate the effect of lithium chloride on the early stage of obesity.The experimental process is as follows: Inject either 100 mg/kg or 200 mg/kg of lithium chloride solution into each one of mice for three weeks;record the mouse body weight during the experimental period;check the expression of β-catenin and PPARγ by the methods semi-quantitative RT-PCR and Western blot;Use saline treatment group as a control group.Experimental results indicate that for the lithium-chloride-treated mice,the growth r...
