Introduction: Diabetic kidney disease (DKD) is the major cause of end-stage renal disease; however, the pathogenesis of this disease is not fully understood. Currently available therapies are not totally efficacious in the treatment and prognosis of DKD, suggesting that further understanding of the molecular mechanisms underlying the pathogenesis of this disease is necessary to improve its management. Recently, research on microRNAs (miRNAs) has become a hotspot because of the...

Introduction: Long-term insulin independence after pancreatic islet transplantation depends on the engraftment of a large number of viable islets. However, the yield and quality of islets isolated from brain-death (BD) donors are negatively affected by upregulation of proinflammatory cytokines and by hypoxia and oxidative stress that occurs during the BD status. Uncoupling proteins (UCPs) are mitochondrial transporters present in the inner mitochondrial membrane and are associ...

Introduction: Some studies have reported associations between five uncoupling protein (UCP) 1–3 polymorphisms and obesity. This paper describes a case–control study and a meta-analysis conducted to determine if the following polymorphisms are associated with obesity: −3826A/G (UCP1); −866G/A, Ala55Val and Ins/Del (UCP2) and −55C/T (UCP3).Methods: The case–control study enrolled 282 obese and 483...

Background and aims: Diabetic kidney disease (DKD) is a common microvascular complication that affects 40% of patients with diabetes mellitus (DM). Emerging evidence suggests a role for microRNAs (miRNAs) in the development of DKD. In this context, miR-15a-5p and miR-30e-5p have been shown to regulate the expression of the uncoupling protein 2, a mitochondrial protein that decreases reactive oxygen species (ROS) formation by mitochondria. Since ROS overproduction is a key cont...

Aims: Some studies have reported associations between uncoupling protein (UCP) 1–3 polymorphisms and obesity or related-features. However, other studies have failed to confirm these associations. Thus, this study describes a cross-sectional study and a meta-analysis conducted to attempt to determine whether the -3826A/G (UCP1), -866G/A, Ala55Val and Ins/Del (UCP2) and -55C/T (UCP3) polymorphisms are associated with body mass index (BMI)...

Context: Diabetic kidney disease (DKD) is a common microvascular complication that affects approximately 40% of patients with diabetes mellitus (DM). This complication is the leading cause of end-stage renal disease (ESRD) in patients starting renal replacement therapy and is associated with increased cardiovascular mortality. Although a tight glycemic control is able to reduce the development and delay the progression of DKD, current therapies are still not totally effective ...

Introduction: Pancreatic islet transplantation is an effective treatment for patients with type 1 diabetes mellitus (T1DM) with unstable metabolic control. However, the quality of islets isolated from a donor is negatively affected by the inflammatory environment related to the donor’s brain death and by the stress related to islet isolation and culture. To overcome islet quality loss, some studies have co-cultured islets with mesenchymal stromal cells (MSCs). Considering...
