Relation of lipoprotein lipase activity in adipose tissue to adipocyte volume and its influence in...

In the subcutaneous adipose tissue of 20 normal weight and overweight subjects with normo- or hypertriglyceridemia, the relation is examined between the lipoprotein lipase activity (LPLA) per gram adipose tissue and adipocyte volume. The following findings were obtained: 1. Significant positive correlations between the LPLA per gram adipose tissue and the adipocyte volume were ascertained in the groups of subjects having normal triglyceridemia or exhibiting hypertriglyceridemia. 2. The negative relation between the LPLA in the adipose tissue and the triglyceride level in serum described in literature could not be verified. Across a glyceride span of 76 to 600 mg% in serum we found a correlation coefficient of +0.34. 3. It can therefore be assumed that the LPLA per gram adipose tissue with increasing adipocyte volume does not represent an inhibiting factor to the triglyceride in serum breakdown in the development of hypertriglyceridemia.
