Diabetic cardiomyopathy (DbCM) is commonly defined as ventricular dysfunction in a person living with diabetes in the absence of hypertension and/or coronary artery disease (CAD). There is increasing recognition in the field that this is a poor definition to reflect the pathology of DbCM, as many individuals with diabetes (both type 1 and type 2) […]

Thickening of the glomerular basement membrane (GBM) is one of the most common pathological changes in diabetic nephropathy (DN), but its underlying mechanisms remain unclear. Collagen α1(IV) is predominantly expressed by endothelial cells and upregulated in the glomeruli in DN. Glucose transporter type 1 (GLUT1) serves as the primary transporter for glucose uptake in endothelial […]

One-third of patients with diabetes will develop end-stage kidney disease, and approximately one-half of the patients requiring kidney transplantation in the U.S. suffer from diabetes. In 2002, Yamada, Sachs, and their colleagues explored the renal subcapsular site for islet implantation in a partially inbred miniature swine model. All pancreatectomized pigs that received autologous islets under […]

Abdominal obesity with hyperinsulinemia reflects a prediabetic risk state signified by metabolic inflexibility and an overreliance on glucose as a metabolic fuel in skeletal muscle. There is limited information on net metabolic substrate flux across human skeletal muscle under physiological and pathophysiological conditions. Using arteriovenous difference sampling across the forearm in overweight (n = 9) […]

Large-scale multiancestry genome-wide association studies have identified hundreds of loci associated with type 2 diabetes (T2D) and glycemic traits, yet imputed genotyping arrays limit the detection of low-frequency and rare variants. Whole-genome sequencing (WGS) offers a more complete view of genetic variation, especially across diverse populations. We analyzed high-coverage (38×) WGS data from 21,913 T2D […]

Type 2 diabetes (T2D) impairs antiviral immunity; however, the causal link between T2D and interferon-α2 (IFN-α2) deficiency remains unclear. This study used genome-wide association study–based Mendelian randomization (MR) to investigate this relationship and validated the findings in an H1N1-infected diabetic mouse model. MR analysis of 26 single nucleotide polymorphisms showed a significant negative association between […]

Home to the headwaters of nine rivers, Algonquin Provincial Park contains thousands of lakes and hundreds of miles of streams, waterways that historically have played a crucial role in Ontario’s lumber industry. During her second year of undergraduate studies at the University of Western Ontario, Erin Mulvihill did a research project sampling benthic invertebrates, the […]
