Differential display PCR was used to identify alternate expression of serum glucocorticoid-regulated kinase (Sgk) mRNA in diabetes-induced renal disease. Differential expression of Sgk mRNA was identified in the kidneys of normal and obese db/db mice, a model of select aspects of human diabetic nephropathy. Sgk mRNA was selectively increased in diabetic mouse kidneys. The Sgk mRNA levels remained constant in other tissues from obese db/db mice. An increase in Sgk mRNA was also observed in the human diabetic kidney. In addition, thrombin, which may play a role in the progression of renal disease, increased Sgk message in cell culture. Because the diabetes-induced increase in Sgk was only observed in the kidney, which is particularly susceptible to diabetes-induced damage, Sgk may play a role in diabetic nephropathy.
