Evaluation of sirtuin 1 (SIRT1) levels in autosomal dominant polycystic kidney disease.

Autosomal dominant polycystic kidney disease (ADPKD) is the most common genetic kidney disease and the majority of patients have a PKD-1 or PKD-2 mutation. Sirtuin 1 (SIRT1) has roles in cellular aging, antioxidant activity, cellular proliferation. In an experimental study, inhibition of SIRT1 was found to delay renal cyst development in ADPKD. The purpose of this study is to determine the SIRT1 levels in ADPKD patients. To our knowledge, this is the first study that investigating blood and urine SIRT1 levels in ADPKD patients. Sixty-seven patients with ADPKD and 34 control cases with normal renal functions and without renal cysts were included in this study. Serum and urine SIRT1 concentrations were determined by human enzyme-linked immunosorbent assay (ELISA) kit. 24-h urine samples were used for urine SIRT1 measurements. The urine SIRT1 levels were statistically significantly lower in ADPKD patients group (p < 0.001). Although blood SIRT1 levels of ADPKD patients were higher than control cases but there were no statistically significant difference between the groups in terms of blood SIRT1 levels. Urine SIRT1 levels (β = 2.452, CI 95% 1.419-4.239, p = 0.001) were found an independent factor in multivariate regression analysis for ADPKD. Urine SIRT1 levels were lower in ADPKD patients than control group. The low urinary SIRT1 levels despite the similar blood SIRT1 levels might be due to the impaired metabolism of SIRT1 in ADPKD patients; this state might has a role in cyst development. © 2021.
