Graphical Abstract:


Background: The renin-angiotensin system (RAS) is a critical contributing factor to obesity and related diseases. Several studies have shown the relationship of obesity with cyclooxygenase-2.

Objectives: Based on these facts, we aimed to investigate the celecoxib oral administration (a selective anti-inflammatory inhibitor of cyclooxygenase-2 (ICOX-2)) effects, in mice fed a high-fat diet by assessing the renin-angiotensin system and inflammatory markers expression.

Methods: FVB/N male mice were divided into 3 groups and fed with experimental diets, standard, high-fat diet and high-fat diet plus ICOX-2 at a dose of 100mg/kg/body weight. Body weight, food intake, blood parameters and RAS/inflammatory markers expression were assessed.

Results: The main findings showed that diet-induced obese mice treated with COX-2 inhibitor showed significantly improved glucose and insulin homeostasis, presented decreased body weight gain and the biochemical analyses revealed reduced triglyceride levels and higher serum HDL-c levels as compared to HFD and ST. These results were accompanied by a downregulation of AGT, ACE, TNF-α and IL-6 expression in the group receiving treatment.

Conclusion: Taken together, these results indicate that ICOX-2 may exhibit therapeutic potential for obesity via the renin-angiotensin system and inflammation.

Keywords: Cyclooxygenase-2, metabolic disorder, nonsteroidal anti-inflammatory drug, obesity, renin-angiotensin system, modulates.
