Depot-related gene expression in human subcutaneous and omental adipocytes

Abstract

Human omental adipocytes display a range of biochemical properties that distinguish them from adipocytes of subcutaneous origin. However, information about site-related gene expression in human fat cells is limited. We have previously demonstrated that leptin mRNA is markedly overexpressed in abdominal subcutaneous (SC) compared with omental (Om) adipocytes. To further investigate depot-specific differences in adipocyte gene expression, we have measured, in paired samples of isolated human adipocytes obtained from SC and Om fat depots, the expression of mRNAs encoding a number of proteins involved in the control of adipocyte metabolism. In contrast to the marked site-related expression of le..
