Abstract

The anti-atherogenic potential of liver X receptors (LXRs) has been attributed to their inhibitory role in macrophage-mediated inflammation and promotion of reverse cholesterol transport. This study aimed to evaluate the efficacy of an LXR agonist, 1,8-cineole (Eucalyptol), in atherosclerosis through network pharmacology, molecular docking, and in vivo efficacy studies in high-fat-diet-induced atherosclerosis in hamsters. Network pharmacology analysis was performed by identifying potential targets of 1,8-Cineole and atherosclerosis, followed by the construction of component-target-disease and protein-protein interaction networks. Gene Ontology and KEGG pathway enrichment analysis of targets were performed. The top 5 targets were selected for molecular docking studies. Atherosclerosis was induced in male Golden Syrian hamsters, and the results of network pharmacology were verified. Fifty-one overlapped targets were identified for 1,8-cineole and atherosclerosis. In the protein-protein interaction studies, the top 5 ranked proteins were PPARG, FXR, ABCA-1, ABCG1, and LXRΑ. KEGG pathway analysis and molecular docking showed that ABCA-1 and LXRΑ were correlated in atherosclerosis. Animal studies showed amelioration of atherosclerotic lesions in the aorta of animals treated with 1,8-cineole compared to disease control aortas. A dose-dependent attenuation in ABCA-1 levels and inflammatory markers was observed in animals treated with 1,8-cineole, comparable to its levels in normal animals. In conclusion, 1,8-cineole showed anti-atherosclerotic effects in Golden Syrian hamsters via LXRΑ-induced ABCA-1 overexpression.
