Non-invasive and simple to measure biomarkers are still an unmet need for myotonic dystrophy type 1 (DM1). Indeed, muscle biopsies can be extremely informative, but their invasive nature limits their application. Extracellular microRNAs are emerging humoral biomarkers and preliminary studies identified a group of miRNAs that are deregulated in the plasma or serum of small groups of DM1 patients. Here we adopted very stringent selection and normalization criteria to validate or disprove these miRNAs in 103 DM1 patients and 111 matched controls...

Neuropsychological examinations in myotonic dystrophy (DM) patients show a great variability of results from a condition of intellectual disability to the subtle cognitive impairments. It is unclear if different clusters of neuropsychological deficits appear in different phenotypes of DM, or if there are patients with no cognitive deficit at all. The aim of this study is to assess cognitive impairments among patients with different phenotypes of DM type 1 (DM1) and type 2 (DM2), and to potentially define cognitive clusters in these disorders...

Pei Guo, Sik Lok Lam
CCTG repeat expansion in intron 1 of the cellular nucleic acid-binding protein (CNBP) gene has been identified to be the genetic cause of myotonic dystrophy type 2 (DM2). Yet the underlying reasons for the genetic instability in CCTG repeats remain elusive. In recent years, CCTG repeats have been found to form various types of unusual secondary structures including mini-dumbbell (MDB), hairpin and dumbbell, revealing that there is a high structural diversity in CCTG repeats intrinsically. Upon strand slippage, the formation of unusual structures in the nascent strand during DNA replication has been proposed to be the culprit of CCTG repeat expansions...

The C-terminal domain of the three-domain-comprising trehalose synthase from Thermus thermophilus was truncated in order to study the effect on the enzyme's activity and substrate specificity. Compared with the wild-type (WT) enzyme, the two truncated enzymes (DM1 and DM2) showed lower maltose- and trehalose-converting activities and a different transglycosylation reaction mechanism. In the mutants, the glucose moiety cleaved from the maltose substrate was released from the enzyme and intercepted by external glucose oxidase, preventing the production of trehalose...

The prevalence of Human Herpesvirus 8 (HHV8) DNA and antiviral antibodies in Diabetes type 2 (DM2) and control subjects was studied, in order to confirm a possible link between DM2 and HHV8 infection. The HHV8-DNA from diabetic patients was typed for detecting possible genomic differences with known HHV8 reference viruses.DM2 patients and healthy controls were examined for the presence of HHV8 DNA into the peripheral blood lymphocytes. Both anti-lytic and latent phase antibodies were detected in HHV8 positive and negative diabetic patients, as well in a number of controls...

BACKGROUND: Diabetes mellitus (DM) influences the trigeminal nerve function by changing the pain response and transduction of the orofacial sensory pathways. It affects the inflammatory response via neuropeptide Y (NPY) and vascular endothelial growth factor (VEGF), which could potentially have a relevant role in the pathophysiology of diabetic neuropathy. The aim was to investigate expression of VEGF and NPY in subpopulations of trigeminal ganglion (TG) neurons in rat models of early DM1 and DM2...

Type 2 diabetic mellitus (DM2) is associated with accelerated thrombotic complications and is characterized by high levels of plasminogen activator inhibitor-1 (PAI-1). Recent studies show that human platelets have high levels of miR-30c and synthesize considerable active PAI-1. The underlying mechanism of how PAI-1 expression is upregulated in DM2 is poorly understood. We now report that hyperglycaemia-induced repression of miR-30c increases PAI-1 expression and thrombus formation in DM2. Bioinformatic analysis and identification of miRNA targets were assessed using luciferase assays, quantitative real-time PCR and western blots in vitro and in vivo...

BACKGROUND: Obesity is an independent cardiovascular risk factor and a catalyst of other cardiovascular risk factors, such as hypertension, dyslipidemia, type 2 diabetes mellitus (DM2) and metabolic syndrome. METHODS: We analyzed cardiovascular risk in obese patients before and after sleeve gastrectomy (SG). To this end, we studied changes in body mass index (BMI), blood chemistry parameters that characterize the risk of atherosclerosis and instrumental parameters (objective markers of this risk), namely intima-media thickness (IMT) and flow-mediated dilation (FMD), the latter reflecting endothelial function...

BACKGROUND: Correction of metabolic acidosis (MA) with nutritional therapy or bicarbonate administration is widely used in chronic kidney disease (CKD) patients. However, it is unknown whether these interventions reduce insulin resistance (IR) in diabetic patients with CKD. We sought to evaluate the effect of MA correction on endogenous insulin action in diabetic type 2 (DM2) CKD patients. METHODS: A total of 145 CKD subjects (83 men e 62 women) with DM2 treated with oral antidiabetic drugs were included in the study and followed up to 1 year...

Cardiovascular diseases (CVD) are major causes of death and illness worldwide. In recent decades an increased prevalence of CVD mortality has been reported in low-medium income countries, which has been associated with changes in life styles, deficiencies in health systems and the persistence of social inequities.The metabolic syndrome comprises a cluster of cardiometabolic risk factors, with insulin resistance and increased adiposity as its central features. Identifying individuals with metabolic syndrome is important due to its association with an increased risk of coronary heart disease and type 2 diabetes mellitus (DM2)...

The primary aim of the research was to assess the level of trace elements and electrolytes in serum of postmenopausal diabetic women. Sixty-four postmenopausal women with type 2 diabetes mellitus (DM2) and 64 age- and body mass index-matched controls were examined. Serum trace elements were assessed using inductively coupled plasma dynamic reaction cell mass spectrometry (ICP-DRC-MS). Fasting plasma glucose (FPG) and glycated hemoglobin (HbA1c) levels were evaluated using Randox kits. The obtained data demonstrate that DM2 patients were characterized by 42 and 34 % higher FPG and HbA1c levels, respectively (p < 0...

BACKGROUND AND AIMS: Older adults with type 2 diabetes mellitus (DM2) exhibit accelerated decline in some domains of cognition including verbal episodic memory. Few studies have investigated the influence of DM2 status in older adults on recognition memory for more complex stimuli such as faces. In the present study we sought to compare recognition memory performance for words, objects and faces under conditions of relatively low and high cognitive load. METHODS: Healthy older adults with good glucoregulatory control (n = 13) and older adults with DM2 (n = 24) were administered recognition memory tasks in which stimuli (faces, objects and words) were presented under conditions of either i) low (stimulus presented without a background pattern) or ii) high (stimulus presented against a background pattern) cognitive load...

Alzheimer's disease (AD) and type II diabetes mellitus (DM2) are the most common aging-related diseases and are characterized by β-amyloid and amylin accumulation, respectively. Multiple studies have indicated a strong correlation between these two diseases. Amylin oligomerization in the brain appears to be a novel risk factor for developing AD. Although amylin aggregation has been demonstrated to induce cytotoxicity in neurons through altering Ca(2+) homeostasis, the underlying mechanisms have not been fully explored...

Myotonic dystrophy (DM) and facioscapulohumeral muscular dystrophy (FSHD) are the two most common adult muscular dystrophies and have progressive and often disabling manifestations. Higher levels of medication adherence lead to better health outcomes, especially important to patients with DM and FSHD because of their multisystem manifestations and complexity of care. However, medication adherence has not previously been studied in a large cohort of DM type 1 (DM1), DM type 2 (DM2), and FSHD patients. The purpose of our study was to survey medication adherence and disease manifestations in patients enrolled in the NIH-supported National DM and FSHD Registry...
