Abstract

In recent years, evidence has emerged indicating that insulin resistance and diabetes mellitus type 2 are associated with inflammation of adipose tissue (AT). Interest has been focused on epicardial AT (EAT) because of its possible involvement with atherosclerosis and cardiovascular diseases. The aim of this study was to characterize adipocyte size and inflammatory profile in subcutaneous (SAT) and EAT among subjects with or without diabetes. Biopsies were collected from SAT and EAT in 34 men undergoing elective cardiac surgery. Weight, height, body mass index, waist circumference, as well as serum levels of glucose, insulin, lipids, adiponectin, and leptin were determined in all subjects. Adiponectin, MCP-1, and CD68 mRNA levels present within cells from AT biopsies were determined by real-time polymerase chain reaction. Adipocyte size was determined by optic microscopy and morphometry. Regarding the experimental group as a whole, gene-expression levels within EAT were significantly lower for adiponectin and higher, albeit not significantly, for MCP-1, when compared with that of SAT. In addition, adipocytes in EAT were significantly smaller than those in SAT. Subjects with diabetes showed lower adiponectin gene-expression levels in both SAT and EAT when compared with subjects without diabetes. By contrast, MCP-1 and CD68 gene-expression levels were higher in both tissue types of diabetic subjects. Adipocyte size in EAT was significantly larger in diabetic subjects than in nondiabetic subjects. Our data revealed a predominantly inflammatory profile in both SAT and EAT in subjects with diabetes in comparison with those without diabetes.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
