Podocyte injury is an early event in diabetic kidney disease and is a hallmark of glomerulopathy. MicroRNA-146a (miR-146a) is highly expressed in many cell types under homeostatic conditions, and plays an important anti-inflammatory role in myeloid cells. However, its role in podocytes is unclear. Here, we show that miR-146a expression levels decrease in the glomeruli of patients with type 2 diabetes (T2D), which correlates with increased albuminuria and glomerular damage. MiR-146a levels are also significantly reduced in the glomeruli of albuminuric BTBR ob/ob mice, indicating its significant role in maintaining podocyte health...

Certain microRNAs (miRNAs) targeting the molecules in the insulin signaling cascades are dysregulated by saturated fatty acids (SFA), which can lead to insulin resistance and type 2 diabetes. This article reports the accompanying data collected using miRNAs microarrays to identify the changes in miRNA expression in HepG2 cells treated with SFA palmitate. Differentially expressed miRNA analyses in HepG2 cells showed that a range of upregulated (>1.5-fold) or downregulated (<0.5-fold) miRNAs. Further extensive insights into the implications of miRNAs, particularly miR-1271, in HepG2 cells can be found in "MiR-1271 upregulated by saturated fatty acid palmitate provokes impaired insulin signaling by repressing INSR and IRS-1 expression in HepG2 cells" (W...

Head and neck squamous cell carcinoma (HNSCC) is the sixth leading cause of cancer worldwide. The treatment of choice in case of head and neck cancer is surgery, followed by chemo- or/and radiotherapy. A potentially effective instrument to improve the outcome of numerous diseases, including viral infections, diabetes and cancer, is RNA interference (RNAi). It has been demonstrated that small interfering RNA and microRNA molecules are strongly involved in the regulation of various different pathological processes in cancer development...

MicroRNA-122 (miR-122) is abundant in the liver and involved in lipid homeostasis, but its relevance to the long-term risk of developing metabolic disorders is unknown. We therefore measured circulating miR-122 in the prospective population-based Bruneck Study (n=810; survey year: 1995). Circulating miR-122 was associated with prevalent insulin resistance, obesity, metabolic syndrome, type-2 diabetes, and an adverse lipid profile. Among 92 plasma proteins and 135 lipid subspecies quantified with mass spectrometry, it correlated inversely with zinc-alpha-2-glycoprotein and positively with afamin, complement-factor H, VLDL-associated apolipoproteins, and lipid subspecies containing monounsaturated and saturated fatty acids...

Epigenetic changes play a pivotal role in the development of a wide spectrum of human diseases including cardiovascular diseases, cancer, diabetes, and intellectual disabilities. Cardiac fibrogenesis is a common pathophysiological process seen during chronic and stress-induced accelerated cardiac aging. While adequate production of extracellular matrix (ECM) proteins is necessary for post-injury wound healing, excessive synthesis and accumulation of extracellular matrix protein in the stressed or injured hearts causes decreased or loss of lusitropy that leads to cardiac failure...

Apoptosis, one of the major causes of podocyte loss, has been reported to have a vital role in diabetic nephropathy (DN) pathogenesis, and understanding the mechanisms underlying the regulation of podocyte apoptosis is crucial. Metadherin (MTDH) is an important oncogene, which is overexpressed in most cancers and responsible for apoptosis, metastasis, and poor patient survival. Here we show that the expression levels of Mtdh and phosphorylated p38 mitogen-activated protein kinase (MAPK) are significantly increased, whereas those of the microRNA-30 family members (miR-30s) are considerably reduced in the glomeruli of DN rat model and in high glucose (HG)-induced conditionally immortalized mouse podocytes (MPC5)...

Prevalence of Type 2 Diabetes Mellitus (T2DM) has reached pandemic levels in Western societies. T2DM begins with the development of peripheral insulin resistance which prior research suggests may commonly originate within skeletal muscle. A number of mechanisms have been proposed for the development of muscle insulin resistance including those of classical glucose handling, but also other cellular derangements observed in this disease which include mitochondrial degeneration, alterations in muscle protein turnover and early evidences for dysregulation of microRNAs...

MicroRNAs (miRNAs) play vital roles in the development of diabetic nephropathy. Here, we compared the protective efficacies of miR-26a and miR-30c in renal tubular epithelial cells (NRK-52E) and determined whether they demonstrated additive effects in the attenuation of renal fibrosis. TGFβ1 suppressed miR-26a and miR-30c expression but up-regulated pro-fibrotic markers in NRK-52E cells, and these changes were also found in the kidney cortex of 40-week-old diabetic Otsuka Long-Evans Tokushima fatty (OLETF) rats...

Today obesity and type 2 diabetes (T2D) have both reached epidemic proportions. However, our current understanding of the primary mechanisms leading to these diseases is still limited due to the complex multifactorial nature of the underlying phenomena. We hypothesize that the levels of specific cytokines and miRNAs vary across the diabetes spectrum and unique signatures associated with them may serve as early biomarkers of the disease and provide insights into respective pathogenetic mechanisms. In this study, we measured the circulating levels of cytokines and microRNAs (miRNAs) in lean and obese humans with prediabetes (n = 21), T2D (n = 17), and healthy controls (n = 20) (ORIGINS trial, NCT02226640)...

Methylglyoxal (MGO) is a reactive dicarbonyl produced as by-product of glycolysis, and its formation is heightened in hyperglycaemia. MGO plasma levels are two-fold to five-fold increased in diabetics and its accumulation promotes the progression of vascular complications. Impairment of endothelium-derived nitric oxide represents a common feature of endothelial dysfunction in diabetics. We previously demonstrated that MGO induces endothelial insulin resistance. Increasing evidence shows that high glucose and MGO modify vascular expression of several microRNAs (miRNAs), suggesting their potential role in the impairment of endothelial insulin sensitivity...

Chronic kidney disease (CKD) represents an important public health problem. Its progression to end-stage renal disease is associated with increased morbidity and mortality. The determinants of renal function decline are not fully understood. Recent progress in the understanding of post-transcriptional regulation of mRNA stability has helped the identification of both the trans- and cis-acting elements of mRNA as potential markers and therapeutic targets for difficult-to-diagnose and -treat diseases, including CKDs such as diabetic nephropathy...

Since the discovery of the first mammalian microRNA (miRNA) more than two decades ago, a plethora of miRNAs has been identified in humans, now amounting to more than 2500. Essential for post-transcriptional regulation of gene networks integral for developmental pathways and immune response, it is not surprising that dysregulation of miRNAs is often associated with the aetiology of complex diseases including cancer, diabetes and autoimmune disorders. Despite massive expansion of small RNA studies and extensive investigation in diverse disease contexts, the role of miRNAs in type 1 diabetes has only recently been explored...

Gene expression control by microRNAs (miRs) is an important mechanism for maintenance of cellular homeostasis in physiological and pathological conditions as well as in response to different stimuli including nutritional factors and exercise. MiRs are involved in regulation of several processes such as growth and development, fuel metabolism, insulin secretion, immune function, miocardium remodeling, cell proliferation, differenciation, survival, and death. These molecules have also been proposed to be potential biomarkers and/or therapeutical targets in obesity, type 2 diabetes mellitus, cardiovascular diseases, metabolic syndrome, and cancer...

Efferocytosis, a process of clearance of apoptotic cells by phagocytes, is essential for successful resolution of inflammation and maintenance of tissue homeostasis. Diabetes compromises the function of macrophages leading to adverse inflammatory response during wound healing, myocardial injury, atherosclerosis and autoimmune disorders. However, the effect of diabetes on macrophage-mediated efferocytosis of apoptotic cardiomyocytes (ACM) and the molecular mechanisms involved are not understood so far. In the present study we found that invitro efferocytosis of ACM was impaired in macrophages from db/db (diabetic) mice...

The risks that arise after splenectomy can be divided in infectious and non-infectious. The link between splenectomy and these hazards remains partially unknown. Host defense against infection is altered after splenectomy and such individuals develop sepsis more easily and the infection has a fulminant course. Splenectomy is also a potential risk factor for several vascular complications that result from partial or total obstruction of an arterial or venous blood vessel. Furthermore, pulmonary hypertensioncan be a severe and sometimes fatal complication following splenectomy...

MicroRNAs (miRNAs) are intracellular and circulating molecular components contributing to genome expression control through binding mRNA targets, which generally results in downregulated mRNA expression. One miRNA can target several mRNAs and one transcript can be targeted by several miRNAs, resulting in complex fine tuning of regulation of gene networks and signaling pathways. miRNAs regulate metabolism, adipocyte differentiation, pancreatic development, β-cell mass, insulin biosynthesis, secretion and signaling and their role in diabetes and obesity is emerging...

Diabetes is generally associated with vasculopathy, which contains both microvascular and macrovascular complications, associated with high morbidity and mortality. Currently, despite interventional therapy, the overall prognosis for patients with diabetic vasculopathy remains unsatisfactory. Angiogenesis and vascular injury and repair are associated with a variety of cells. However, the molecular mechanisms of the cells that are involved in pathogenesis of diabetic vasculopathy remain largely unknown. As novel molecules, microRNAs (miRs) take part in regulating protein-coding gene expression at the post-transcriptional level, and contribute to the pathogenesis of various types of chronic metabolism disease, especially diabetic vasculopathy...
