Outline of Final Research Achievements

Rac1, which is one of the GTPases of the Rho subfamily, has crucial role for cytoskeletal architecture and the regulation of cell migration and growth. However, renal injury in mice with podocyte-specific deletion of Rac1 has yet to be elucidated fully due to conflicting findings. Here, we identified the possible role for Rac1 in podocytes of streptozotocin (STZ) induced diabetic mice.
Our results provided the evidence that podocyte-specific deletion of Rac1 results in morphological alteration in podocyte, and induction of apoptosis or decreased expression of the slit diaphragm proteins by hyperglycemic stimuli are associated with progression of diabetic nephropathy.
