Abstract: Objective: To investigate the effects of aerobic exercise on Cdc2-like kinase (CLK2) protein expression and the fat content in liver of mice fed with high fat diet. Methods: C57BL/6 mice were distributed in normal diet, high fat diet (fed with highfat diet during 16 weeks) and trained high fat diet group (fed with high-fat diet during 16 weeks and exercised during 8 weeks),10 mice in each group. The expression of CLK2 protein in liver of each group was detected by Western blot. The fat content of liver in each group was detected by oil red O staining, and the relative genes of fat metabolism in each group were evaluated by real-time quantitative PCR.Results: The mice fed with high fat diet showed insulin resistance, the hepatic CLK2 content and fat content were increased compared to the normal diet group. Otherwise, the chronic physical exercise improved insulin resistance state, prevented the increasing of CLK2 in the liver and attenuated hepatic fat accumulation.Conclusion: Aerobic exercise could reduce the expression of CLK2 protein in the liver of mice fed with high fat diet.

Key words: aerobic exercise, high fat diet, Cdc2-like kinase, hepatic fat accumulation, mice
