  • Method for inhibition of lipogenesis by regulating PRP19 expression
    Publication number: 20060258609
    Abstract: The downregulation of PRP 19 (precursor RNA processing 19) protein expression results in effectively reducing the expression of SCD1 (stearyl CoA desaturase-1), the key lipogenic enzyme, and its down-stream triacylglycerol synthesis enzymes, DGAT-1 (diacyglycerol acyltransferase-1) and GPAT (glycerol-phosphate acyltransferase), as well as the intracellular content of neutral lipids, the major target for treating obesity.
