Abstract
Phosphorylation of extracellular-signal-regulated kinase 1/2 (p-ERK 1/2) was investigated by immunohistochemistry at 30 min, 1 h, and 48 h after nerve transection in the sciatic nerve of healthy and diabetic [streptozotocin (STZ)-induced diabetes mellitus and BioBreeding (BB; i.e. DR.lyp/lyp or BBDP)] rats. Transection injury increased the intensity of p-ERK 1/2 in nerve stumps at all time points. Staining was confined to Schwann cells with occasional faint staining in single axons. In diabetic rats, a lower intensity of p-ERK 1/2 was found at 1 and 48 h in the distal and proximal nerve stumps compared with healthy rats. STZ-induced diabetic rats were not different from BB rats. p-ERK 1/2 is activated differentially in Schwann cells after... (More)

STZ-induced diabetic rats were not different from BB rats. p-ERK 1/2 is activated differentially in Schwann cells after nerve injury in diabetic rats, whereas activation in STZ-induced diabetic rats did not differ from BB rats.
