Project description:Diabetes mellitus (DM) after transplantation remains a crucial clinical problem in kidney transplantation. To obtain insights into molecular mechanisms underlying the development of post-transplant diabetes mellitus (PTDM) and its early impact on glomerular structures, here we comparatively analyze the proteome of histologically normal appearing glomeruli from patients with PTDM from normoglycemic (NG) transplant recipients, and from recipients with pre-existing type 2 DM (PTDM)
Project description:There is a close relationship between hyperglycemia in diabetes and progression of periodontal disease. This study aims to investigate the effect of hyperglycemia on the barrier function of gingival epithelial cells as a cause of hyperglycemia-exacerbated periodontitis in diabetes mellitus. Abnormal expressions of adhesion molecules in gingival epithelium in diabetes were compared between db⁄db and control mice.
Project description:Type 2 diabetes mellitus represents a major health problem with increasing prevalence worldwide. Limited efficacy of current therapies have prompted a search for novel therapeutic options. Here we show that treatment of pre-diabetic mice with mitochondrially targeted tamoxifen, a potential anti-cancer agent with senolytic activity, improves glucose tolerance and reduces body weight with most pronounced reduction of visceral adipose tissue due to reduced food intake, suppressed adipogenesis and elimination of senescent cells. Glucose-lowering effect of mitochondrially targeted tamoxifen is linked to improvement of type 2 diabetes mellitus-related hormones profile and is accompanied by reduced lipid accumulation in liver. Lower senescent cell burden in various tissues, as well as its inhibitory effect on pre-adipocyte differentiation, results in lower level of circulating inflammatory mediators that typically enhance metabolic dysfunction. Targeting senescence with mitochodrially targeted tamoxifen thus represents an approach to the treatment of type 2 diabetes mellitus and its related comorbidities, promising a complex impact on senescence-related pathologies in aging population of patients with type 2 diabetes mellitus with potential translation into the clinic.
Project description:Salivary exsomal miRNAs may play important role in the pathogenesis of chronic inflammatory disease, such as periodontitis. There are many studies which suggested the connection between periodontitis and systemic disease, however, the role of specific miRNA as a intersection of periontitis and diabetes are not elucidated. We suggested miR-25-3p as possible common mediator in the pathogenesis of periodontitis and diabetes.
Project description:Type 2 diabetes mellitus (DM) is a complex metabolic disorder and leads to various complications including periodontitis (PD). Though bidirectional relationship of DM and PD has been reported, however, their immunological relationship remain poorly understood. This study aims to compare the immune response in patients with PD only and those with both PD and DM (PDDM), in order to expand our knowledge of the complicated connections between PD and DM. We collected peripheral blood mononuclear cells (PBMCs) from three distinct groups: 11 healthy control subjects, 10 patients with PD without DM, and 6 patients with PDDM. PBMCs were analyzed using single-cell RNA sequencing.
Project description:To evaluate whether serum micoRNAs can be biomarkers for diagnosis of type 1 diabetes mellitus, we analyzed the serum microRNA expression profiles in 6 patients with new-onset type 1 diabetes mellitus and 6 age- and gender-matched healthy controls. A difference was observed in 31 miRNAs between the patients and controls (fold change ≥ 2, P < 0.05)
