Research Abstract |
In glomerular diseases, reducing proteinuria is considered as a principal therapeutic target to improve renal outcomes.. Unfortunately, however, some patients develop treatment-resistant proteinuria, resulting in end stage renal disease. In these patients, protecting proximal tubular epithelial cells (PTECs) against proteinuria may be the next therapeutic target to improve renal outcomes. Obesity and aging are independent risk factors for a rapid decline in renal function inpatients with glomerular diseases. Since the severity of proteinuria-induced tubulointerstitial lesions is correlated with renal outcomes, obesity and aging may exacerbate proteinuria-induced tubulointerstitial lesions. If so, identifying the molecular mechanisms underlying obesity- and aging-mediated PTEC vulnerability may lead to new therapy that improves renal outcome in patients with proteinuria. We thus tried to identify a new therapeutic candidate genes by using cDNA microarray analysis in the kidney samples from obese and aged mice with proteinuria. In this study, we have identified a new candidate gene involved in the mechanism underlying obesity- and aging-mediated worsening of proteinuria-induced tubulointerstitial lesion
