Research Abstract |
Senescence marker protein-30 (SMP30) decreases with age and contributes to the symptoms of aging. In this study, we investigated the effect of SMP30 deficiency on the pathogenesis of diabetic nephropathy using streptozocin induced diabetic SMP30 knockout (KO) mice. Tubular damages with tubulointerstitial fibrosis were observed in non-diabetic KO mice, and diabetes exacerbated these changes. On the other hand, SMP30 deletion did not affect glomerular changes. The accumulation of HIF-1alpha, the increase of oxidative stress, and tubular inflammation were associated with tubular injuries. In conclusion, decreased SMP30 with age may contribute to the progression of diabetic nephropathy through tubular damages.
