Soluble receptor for advanced glycation end products (sRAGE) is a decoy receptor which sequesters RAGE ligands and acts as a cytoprotective agent. To date, it is unclear whether the lower sRAGE levels observed in obesity are a marker of increased overall adiposity or reflect increases in particular fat depots. Therefore, we evaluated in healthy women the relationship among sRAGE and indicators of adiposity, including abdominal visceral (VAT) and epicardial visceral (EAT) adipose tissues, to explore the potential role of sRAGE as an earlier biomarker of cardiometabolic risk.

Plasma sRAGE levels were quantified by an enzyme-linked immunosorbent assay in 47 healthy women. Total fat mass (FM) and fat-free mass were estimated with bioimpedance analysis. Anthropometric measures and biochemical data were recorded …
