Abstract Objective: To investigate the role of PON1 in diabetic nephropathy and elucidate the underlying mechanisms using a cellular model. Materials and methods: A diabetic nephropathy model was established using high glucose-induced HK-2 cells. Potential target genes and signaling pathways were identified through bioinformatics databases, and PON1 expression was manipulated to interfere with these pathways. The effects of different treatments on cell conditions were systematically evaluated. Results: PON1, the targeted gene in diabetic nephropathy, was significantly downregulated in high glucose-induced […]

Abstract Objective: To evaluate the association between diabetic retinopathy, diabetic kidney disease, and the 10-year risk of atherosclerotic cardiovascular disease in patients with diabetes. Subjects and methods: A cross-sectional study was performed involving patients diagnosed with either type 1 or type 2 diabetes mellitus. Participants were classified into four groups: DM (patients without diabetes-related complications), DR (patients with diabetic retinopathy only), DKD (patients with diabetic kidney disease only), and DR + DKD (patients with both diabetic retinopathy and diabetic kidney […]

ABSTRACT Objective: To investigate the association between the rs3844492/ARHGAP22 and rs741301/ELMO1 polymorphisms and diabetic kidney disease in patients with type 2 diabetes mellitus. Methods: The sample consisted of 740 patients with type 2 diabetes mellitus and diabetic kidney disease (cases) and 303 patients with type 2 diabetes mellitus, but no diabetic kidney disease (controls). The genotyping of the polymorphisms was conducted using real-time polymerase chain reaction with Taqman probes. Results: The frequency of the rs3844492/ARHGAP22 G/G genotype was 16.8% in […]

ABSTRACT Objective Several formulas based in different biomarkers may be used to estimate glomerular filtration rate (GRF). However, all of them have some limitations, and it is very important to evaluate their performances in different groups of patients. Therefore, we compared GFR, as estimated by creatinine-based and cystatin C-based equations, according to albuminuria, in type 1 diabetes (T1DM), in an observational case-control study. Subjects and methods T1DM patients were classified according to albuminuria: normoalbuminuric (n = 63), microalbuminuric (n = […]

The aim of the present study was to review the possible role of dietary lipids in diabetic nephropathy (DN), taking into account associated abnormalities of serum lipids and interaction of dietary and genetic aspects. Dietary lipids may have an important role in the development and progression of DN. The fat diet composition has been associated with DN, particularly with microalbuminuria, serum lipids abnormalities, and endothelial function. However, the beneficial effect of fat intake modification for these patients is not fully […]
