Differences in Upper and Lower Body Adipose Tissue Oxygen Tension Contribute to the Adipose Tissue Phenotype in Humans

Abstract

We demonstrated for the first time, to our knowledge, that AT pO2 is higher in ABD than FEM subcutaneous AT in women who are overweight/with obesity, partly due to a lower oxygen consumption rate in ABD adipocytes. Moreover, low physiological pO2 decreased proinflammatory gene expression and improved the metabolic phenotype in differentiated human adipocytes, whereas more heterogeneous effects on adipokine secretion were found.
