Abstract

|
This study was performed to verify the gene expression of 3T3-L1 using the siRNA of the aromatase gene, which is the estrogen synthesis enzymes. First of all three pairs of siRNA were designed from the CYP19A1 (aromatase) and analyzed the formation of fat cell mechanism by transferring gene to 3T3-L1 and differentiating it. As a result, the expression of leptin gene, which is the main gene causing the obesity, was controlled and the cause of the obesity is related with the insulin specifically. The overexpression of adiponectin and adipsin was observed. This result showed that the formation of the fat was controlled a little without any side effect by obstructing a specific material out of all the signal systems in the fat formation. This study will be an important clue to make it clear that the lack or overexpression of estrogen might be the cause of fat formation mechanism.
