Abstract (original English)
The initial suspicion that obesity increases coronary risk has been much sharpened with the demonstration that risk is more tightly linked to abdominal than to peripheral obesity, and tighter yet again when the mass of omental adipose tissue is taken into account. These data suggest that important metabolic differences might exist between adipocytes from different regions, and indeed, it has long been appreciated that triacylglycerol hydrolysis can be stimulated to a greater extent in omental than in subcutaneous adipocytes. The present study focuses on triacylglycerol synthesis in human subcutaneous and omental adipocytes, a process which, by contrast, has received relatively little attention. Experiments were done on adipose tissue removed at laparotomy and on cultured preadipocytes. With the former, triacylglycerol synthesis was measured in the presence and absence of oleate added to the medium using radiolabeled glucose and oleate as tracers. The results demonstrate that under all conditions examined triacylglycerol synthesis in subcutaneous adipose tissue exceeded that in deep omental adipose tissue. To study the cells in more detail, preadipocytes were cultured and triacylglycerol synthesis was examined again under basal conditions and with stimulation with insulin and acylation stimulating protein (ASP). Under basal conditions, particularly when oleate was added to the m
