Increased thiamine transporter 1 RNA expression in the urinary sediment of type 1 diabetes patients with diabetic kidney disease

چکیده
Aims Thiamine is reabsorbed by the transporters THTR1 and THTR2 (encoded by SLC19A2 and SLC19A3 genes, respectively) in kidney proximal tubule. Decreased plasmatic thiamine concentrations resulting from increased renal clearance was demonstrated in type 2 and type 1 diabetes (T1D) patients. Increased thiamine urinary excretion is an independent risk factor for renal function decline in T1D patients. To evaluate the participation of THTR1 and THTR2 in the pathogenesis of diabetic nephropathy (DN), we studied the expression of SLC19A2 and SLC19A3 in urinary sediment (US) and peripheral blood mononuclear cells (PBMC) in T1D. We also evaluated plasmatic thiamine concentrations to get insights about its status in our population.

Phenol Based RNA Isolation is the Optimum Method for Study of Gene Expression in Human Urinary Sediment
Evaluation of gene expression in urinary sediment has been considered as a promising non-invasive approach for biomarker identification of kidney diseases. Nonetheless, there are several challenges in extraction of RNA from this valuable source of biomarkers, mostly because of the factors that have influence on quality of isolated RNA such as low cellular content. Accordingly, we compared the q...

Increased renal clearance of thiamine (vitamin B(1)) occurs in experimental and clinical diabetes producing thiamine insufficiency mediated by impaired tubular re-uptake and linked to the development of diabetic nephropathy. We studied the mechanism of impaired renal re-uptake of thiamine in diabetes. Expression of thiamine transporter proteins THTR-1 and THTR-2 in normal human kidney sections ...

The present study was conducted to test the effect of Origanum Majoranum Extract (OME) of leaves on alterations induced in a model of type 2 diabetic rats. Adult male Wistar rats were fed high fat diet for 3 weeks and injected a single dose of streptozotocin (35 mg/kg) intraperitoneally to induce type 2 diabetic rats. Diabetic rats were given aqueous extract of OME in a dose of 20 mg/kg orally ...

Introduction: The constantly increasing incidence of type 2 diabetes, probably due to obesity and sedentary life, has led to the increased incidence of macro- and microvascular diabetic complications such as nephropathy. Despite the prompt efforts to develop effective treatments for diabetes and slow the progression of its complications, it is still reported as the most common cause of chronic ...
