Research Abstract |
To lucidate the pathophysiology of nephrotic syndrome, especially FSGS, we investigated myosin IIA. First, We determined the precise localization of myosin IIA; myosin IIA is located at the primary process and cell body of podocye. In human kidney diseases manifesting heavy proteinuria, only in the kidney specimen from the patients with FSGS, the level of expression o myosin IIA was decreased, while in those from other kidney disease patients were not changed. In rat PAN nephrosis model, the expression level of myosin IIA was decreased at day 11 when heavy proteinuria was observed. Taken together, myosin IIA play the very important role in the development of human idiopathic nephrotic syndrome, especially FSGS.
