Abstract:

Objective To observe the parthanatos involved in tubular cell damages of kidney in rats with type 2 diabetics.
Methods Animal models of type 2 diabetics were established. Light microscopy, electron microscopy, immunohistochemistry and
Western blotting were used in this study. Results A large number of glycogen accumulation, cell swelling, and partial necrosis,
mainly for the vacuolar necrosis were seen in early type 2 diabetes renal tubular cells. Immunohistochemical staining of PARP-1
showed that the positive cells were found in epithelium of renal tubules of type 2 diabetic kidney. Compared to the control
kidney, PARP-1 expressed much stronger by immunoblot analysis. Conclusion Necrosis and parthanatos are involved in renal tubule
damages induced by type 2 diabetes in rats.
