ABSTRACT
Background: Chemerin is a recently discovered adipokine that plays a role in adipocyte metabolism. It is a novel chemoattractant adipokine whose expression and secretion are increased by adipogenesis. Aims: To evaluate the effects of probiotic supplementation on chemerin level, inflammation, and metabolic syndrome components in obese Wistar rats. Study Design: Animal experiment. Methods: We divided the experimental animals into three groups, each consisting of eight rats. Group 1 was the control group. Group 2 was the experimentally obese group, in which rats were fed with a high-fat diet. Group 3 was the obese intervention group, in which rats were supplemented with probiotics after obesity induction. Results: At the end of the study, a statistically significant difference was found between the groups in final weights, weight changes, and body mass index values (p<0.05). Weight gain was 34.12±3.70 g in group 3 post-probiotic supplementation and 53.25±8.35 g in group 2 (p<0.05). Obese rats showed increased levels of fasting plasma glucose, insulin, insulin resistance (homeostatic model assessment-insulin resistance), total cholesterol, low-density lipoprotein cholesterol, inflammatory markers, and leptin compared to those in the control group. Chemerin levels were 14.31±13.34 ng/mL in group 2 and 2.67±2.42 ng/mL in group 3 (p<0.05). Conclusion: Probiotic supplementation (group 3) reduced weight gain, and there were positive effects on the levels of fasting plasma glucose, insulin, homeostatic model assessment-insulin resistance, triglycerides, inflammatory markers, leptin, and chemerin.
