ABSTRACT
AIM: The study is aimed to detect the expression of serum Sirtuin 6 (SIRT6) with different severities and urinary albumin creatinine ratios (UACR) in type 2 diabetes mellitus (T2DM) patients, thus exploring the association of SIRT6 together with glycolipid metabolism and urinary protein in the cross-sectional study.
METHODS: T2DM patients (313 cases), pre-diabetic patients (102 cases), and healthy volunteers (100 cases) were selected. T2DM patients were divided into the normal albuminuria (103 cases, UACR < 30 mg/g), micro-albuminuria (106 cases, UACR 30-300 mg/g), and large amount of albuminuria group (104 cases, UACR > 300 mg/g) based on different UACR levels. The medical history was asked, biochemical indicators were detected, hematuria samples were taken, serum SIRT6 levels were detected, and detailed statistical analysis was conducted.
RESULTS: FPG, 2 h-PG, HOMA-IR, HbA1c, and LDL-C increased, while ISI and HDL-C decreased with the aggravation of diabetic status (P < 0.05). HbA1c, UACR, TNFα, HIF1α, and SIRT6 increased with UACR in T2DM patients (P < 0.05). Correlation analysis demonstrated that SIRT6 was significantly positively correlated with glycolipid metabolism in the whole samples, and correlated with UACR, TNFα, and HIF1α in T2DM patients (P < 0.05). Ridge regression analysis showed that SIRT6 was a risk factor for both glycolipid metabolism and urinary protein (P < 0.05).
CONCLUSION: SIRT6 increases with biomarkers in glycolipid metabolism and urinary protein in different severities of diabetes and UACR, which is expected to be a potential biomarker for early prediction and diagnosis related to glycolipid metabolism disorders and related nephropathy. Trial number: ChiCTR2000039808.
