Abstract

Background and objectives: Programmed autophagy is a genetically and evolutionarily conserved process that destroys long-lived cellular proteins and organelles. This study aimed to investigate effects of continuous and interval exercise training with or without atorvastatin supplementation on Beclin1, LC3-I and LC3-П expression in old rats with type 2 diabetes.
Methods: Sixty three male Wistar rats were divided into eight groups. Continuous exercise was performed at a speed of 15-29 m/min for 5-22 minutes. Interval exercise program consisted of six 2.5-minute sets that included a four-minute rest period between each set. The rats in the supplementation groups also received 20 mg/kg body weight atorvastatin daily via intraperitoneal injection. At the end of the training period, the expression of Beclin1, LC3-I and LC3-П in soleus muscle was measured by RT-PCR. One-way ANOVA was used for data analysis at statistical significance of 0.05.
Results: The results showed that both exercise trainings with or without atorvastatin significantly reduced LC3I, LC3-II and Beclin1 compared with the diabetic control group (P<0.05). In addition, the effects of the trainings and atorvastatin supplement did not differ significantly (P>0.05).
Conclusion: The results indicate that continuous and interval exercise program alone and combined with atorvastatin supplementation could significantly reduce LC3-1, LC3-II and Beclin1 level in soleus muscle of old diabetic rats.

Abstract

Background and objectives: Non-alcoholic fatty liver disease (NAFLD) is a chronic liver disease caused by the accumulation of large amounts of fat in the hepatocytes. Given that atorvastatin is effective for treatment of NAFLD, the present study investigated effects of high-fat/fructose diet (HFFD) with atorvastatin on liver enzymes and lipid profile in a NAFLD rat model.
Methods: Thirty-two male Wistar rats were divided into four groups: 1) normal control, 2) HFFD control, 3) HFFD + atorvastatin, and 4) normal + atorvastatin. The groups received HFFD for 15 weeks to induce hepatosteatosis. Atorvastatin was administrated at the dose of 10 mg/kg/day. Lipid profile and liver enzymes were measured after eight weeks of intervention.
Results: Triglyceride, cholesterol, gamma-glutamyl transferase, and aspartate transaminase were significantly reduced in the HFFD + atorvastatin group compared with the HFFD control group. In addition, cholesterol, high-density lipoprotein, alkaline phosphatase, and gamma-glutamyl transferase were significantly increased in the normal + atorvastatin group compared with the normal control group. Low-density lipoprotein increased significantly in the HFFD + atorvastatin group and the normal + atorvastatin group compared with other groups. There was a significant difference in the alanine transaminase levels between the groups taking atorvastatin. In fact, alanine transaminase level was lowest in the normal + atorvastatin group.
Conclusion: Atorvastatin improves the lipid profile and fatty liver and controls liver enzymes. Therefore, it can be used with caution to improve the lipid profile and reduce the complications of NAFLD.
