The etiology of atherosclerosis can be attributed to a disruption in lipid metabolism, specifically cholesterol and low-density lipoprotein cholesterol (LDL-C). PCSK9 is an enzyme that controls the metabolism of LDL-C by degrading the low-density lipoprotein receptor (LDLR), which in turn affects the metabolism of LDL-C. A newly discovered Long Non-coding RNA named <em>LASER</em>, which affects the homeostasis of cholesterol, has been identified through the evaluation of bioinformatics.

Obesity stimulates adipose tissue expansion and adipocyte hypertrophy, resulting in chronic low-grade inflammation in the adipocytes. This enlarged adipocyte secretes a variety of pro-inflammatory chemicals. Because of their endocrine signaling, these substances indirectly promote osteoclast activity and bone-loss. However, the role of COX-2 signaling in obesity-induced bone resorption gene expression has yet to be investigated. Thus, we conducted this study in the context of obesity, employing a high-fat diet-induced obese mouse model. Obese mice treated with a selective and non-selective COX-2 inhibitor (celecoxib and aspirin), significantly (p &lt; 0.05) reduced adipogenic markers such as body and fat weight, serum lipids, mRNA expression of pro-inflammatory markers (COX-2, TNF-α, IL-6, and MCP-1) in adipose tissue and bone resorption markers (OPG, RANKL, Cathepsin K, and MMP-9) in tibia bone tissue. In addition, arachidonic acid (AA) supplementation significantly (p &lt; 0.5) increased the expression of obesity-induced inflammatory cytokines in the tibia bone marrow via the COX-2-derived PGE₂ signaling pathway, hence increase the osteoclastogenesis. These findings suggested that inhibiting the COX-2 signaling pathway could reduce obesity and inflammatory bone resorption.
