摘要:
Our aim was to explore the effects of dietary and behavior interventions on lipometabolism caused by an unhealthy high-fat diet and the best method to rebuild lipid homeostasis of this lifestyle. Apart from normal diet rats, 34 rats were fed with high-fat emulsion for 4 weeks and then intervened for another 4 weeks. Eight of them were classified into high-fat control group, and 9 were sorted into high-fat diet with rice vinegar group. Meanwhile, 10 were put into high-fat diet in swimming group, and 7 were just for refeeding normal diet group. Then, the data of body weight was recorded and analyzed. Indexes of serum samples were tested by kits. AMPKα, HNF1α, and CTRP6 in pancreas, liver, cardiac, and epididymis adipose tissues were detected by western blot. According to our experiments, swimming and refeeding groups reflected a better regulation on lipid homeostasis mainly by upregulating the expression of pancreas AMPKα. To be more specific, the refeeding rats showed lower T-CHO (P < 0.001) and LDL-C (P < 0.05), but higher weight gain (P < 0.001), insulin level (P < 0.01), and pancreas AMPKα (P < 0.01) than high-fat control rats. Compared with rats intervened by swimming or rice vinegar, they showed higher weight gain (P < 0.001), insulin level (P < 0.01), and HNF1α, but lower of CTRP6. In summary, refeeding diet functioned better in regulating the lipometabolic level after high-fat diet. Whatever approach mentioned above we adopted to intervene, the best policy to keep the balance of lipid homeostasis is to maintain a healthy diet.Copyright © 2021 Yuan Yang et al.
