Outline of Final Research Achievements

Mesangial cells have been suggested to be related to the progression of chronic kidney disease in vitro. Therefore, an analysis of the role of mesangial cells by using a new site-specific gene knockout system was performed. Foxd1-Cre or tammoxifen induced Foxd1-Cre mice were mated with TSC1 floxed mice. Knockout of TSC1 caused mammalian target of rapamycin(mTOR) pathway activation in mesangial cells. Then, extracellular matrix in mesangial cells increased. It is the first finding which proves that mesangial-specific cell signal pathway activation can induce chronic kidney disease in vivo.
