Project description:Protein expression profiles in rat corporal smooth muscle tissue were compared between animal models of streptozotocin-induced diabetes mellitus (STZ-DM) and age-matched controls (AMCs) at 1 week and 2 months after induction of hyperglycemia with STZ treatment. At each time point, protein samples from four STZ-DM and four AMC rat corpora tissues were prepared independently and analyzed together across multiple quantitative two-dimensional gels using a pooled internal standard sample to quantify expression changes with statistical confidence. A total of 170 spots were differential expressed among the four experimental groups. A subsequent mass spectrometry analysis of the 170 spots identified a total of 57 unique proteins. Network analysis of these proteins using MetaCore suggested altered activity of transcriptional factors that are of too low abundance to be detected by the two-dimensional gel method. The proteins that were down-regulated with diabetes include isoforms of collagen that are precursors to fibril-forming collagen type 1; Hsp47, which assists and mediates the proper folding of procollagen; and several proteins whose abundance is controlled by sex hormones (e.g. CRP1 and A2U). On the other hand, proteins seen or predicted to be up-regulated include proteins involved in cell apoptosis (e.g. p53, 14-3-3-gamma, Serpinf1, Cct4, Cct5, and Sepina3n), proteins that neutralize the biological activity of nerve growth factor (e.g. anti-NGF 30), and proteins involved in lipid metabolism (e.g. apoA-I and apoA-IV). Subsequent Western blot validation analysis of p53, 14-3-3-gamma, and Hsp47 confirmed increased p53 and 14-3-3-gamma and decreased Hsp47 levels in separate samples. According to the results from the Western blot analysis, Hsp47 protein showed a approximately 3-fold decrease at 1 week and was virtually undetectable at 2 months in diabetic versus control. Taken together, our results identify novel candidate proteins playing a role in erectile dysfunction in diabetes resulting from STZ treatment.

Project description:Erectile dysfunction is a multidimensional but common male sexual dysfunction that involves an alteration in any of the components of the erectile response, including organic, relational and psychological. Roles for nonendocrine (neurogenic, vasculogenic and iatrogenic) and endocrine pathways have been proposed. Owing to its strong association with metabolic syndrome and cardiovascular disease, cardiac assessment may be warranted in men with symptoms of erectile dysfunction. Minimally invasive interventions to relieve the symptoms of erectile dysfunction include lifestyle modifications, oral drugs, injected vasodilator agents and vacuum erection devices. Surgical therapies are reserved for the subset of patients who have contraindications to these nonsurgical interventions, those who experience adverse effects from (or are refractory to) medical therapy and those who also have penile fibrosis or penile vascular insufficiency. Erectile dysfunction can have deleterious effects on a man's quality of life; most patients have symptoms of depression and anxiety related to sexual performance. These symptoms, in turn, affect his partner's sexual experience and the couple's quality of life. This Primer highlights numerous aspects of erectile dysfunction, summarizes new treatment targets and ongoing preclinical studies that evaluate new pharmacotherapies, and covers the topic of regenerative medicine, which represents the future of sexual medicine.

Project description:IntroductionErectile dysfunction (ED) is more common in men with type 2 diabetes mellitus (T2DM), obesity, and/or the metabolic syndrome (MetS).AimThe aim of this study is to investigate the associations among proxy measures of diabetic severity and the presence of MetS with ED in a nationally representative U.S. data sample.MethodsWe performed a cross-sectional analysis of adult participants in the 2001-2004 National Health and Nutrition Examination Survey.Main outcome measuresED was ascertained by self-report. T2DM severity was defined by calculated measures of glycemic control and insulin resistance (IR). IR was estimated using fasting plasma insulin (FPI) levels and the homeostasis model assessment of IR (HOMA-IR) definition. We classified glycemic control using hemoglobin-A1c (HbA1c) and fasting plasma glucose (FPG) levels. MetS was defined by the American Heart Association and National Heart, Lung, and Blood Institute criteria. Logistic regression models, adjusted for sociodemographics, risk factors, and comorbidities, were fitted for each measure of T2DM severity, MetS, and the presence of ED.ResultsProxy measures of glycemic control and IR were associated with ED. Participants with FPG between 100-126 mg/dL (5.6-7 mmol/L) and ? 126 mg/dL (>7 mmol/L) had higher odds of ED, odds ratio (OR) 1.22 (confidence interval or CI, 0.83-1.80), and OR 2.68 (CI, 1.48-4.86), respectively. Participants with HbA1c 5.7-6.4% (38.8-46.4 mmol/mol) and ? 6.5% (47.5 mmol/mol) had higher odds of ED (OR 1.73 [CI, 1.08-2.76] and 3.70 [CI, 2.19-6.27], respectively). When FPI and HOMA-IR were evaluated by tertiles, there was a graded relation among participants in the top tertile. In multivariable models, a strong association remained between HbA1c and ED (OR 3.19 [CI,1.13-9.01]). MetS was associated with >2.5-fold increased odds of self reported ED (OR 2.55 [CI, 1.85-3.52]).ConclusionsPoor glycemic control, impaired insulin sensitivity, and the MetS are associated with a heightened risk of ED.

Project description:Introduction: The human adipose tissue proteome associated with type 2 diabetes (DM) is not well described. An understanding of the DM-specific adipose tissue proteome would provide insight into mechanisms underlying the pathogenesis of DM.
Methods: We used label-free proteomics analysis to quantify differences between visceral adipose tissue samples from obese women with and without DM.
Results: 2640 protein groups were identified and 1965 were subject to statistical analysis. 23 were differently abundant between groups (q < 0.1, moderated t-test, n = 10). Proteins localized to the mitochondria or involved in mitochondrial functions including the TCA cycle and fatty acid metabolism were decreased in abundance in samples from women with DM relative to NDM samples while proteins involved in cytoskeletal function and innate inflammatory signaling pathways were increased.
Conclusion: The visceral adipose tissue proteome in DM is characterized by defects in mitochondrial function, TCA metabolism, inflammation and immunity, and cytoskeletal function. Alterations in the levels of specific proteins associated with these pathways provide insight into mechanisms of adipose tissue dysfunction in the context of metabolic disease.

Project description:BackgroundAlthough several risk factors for erectile dysfunction may be present in patients with cirrhosis, data on the actual prevalence and cause of erectile dysfunction is limited. The International Index of Erectile Function-5 (IIEF-5) is a well-validated survey to determine the presence and severity of erectile dysfunction in men. We assessed (i) the prevalence and severity of erectile dysfunction, and (ii) risk factors for erectile dysfunction in patients with cirrhosis.MethodsIn this prospective study, erectile dysfunction was defined as: absent (>21 IIEF-5-points), mild (12-21) and severe (5-11). Patients with overt hepatic encephalopathy, active alcohol abuse, extrahepatic malignancy, previous urologic surgery, previous liver transplantation and severe cardiac conditions were excluded.ResultsAmong n = 151 screened patients, n = 41 met exclusion criteria and n = 30 were sexually inactive. Thus, a final number of n = 80 male patients with cirrhosis were included. Patient characteristics: age: 53 ± 9 years; model for end-stage liver disease score (MELD): 12.7 ± 3.9; Child-Pugh score (CPS) A: 30 (37.5%), B: 35 (43.8%), C: 15 (18.7%); alcohol: 38 (47.5%), viral: 25 (31.3%), alcohol/viral: 7 (8.8%) and others: 10 (12.5%). The presence of erectile dysfunction was found in 51 (63.8%) patients with 44 (55%) and 7 (8.8%) suffering from mild-to-moderate and moderate-to-severe erectile dysfunction. Mean MELD and hepatic venous pressure gradient (HVPG) were significantly higher in patients with erectile dysfunction (P = .021; P = .028). Child-Pugh score C, MELD, creatinine, age, arterial hypertension, diabetes, low libido, low testosterone and high HVPG were associated with the presence of erectile dysfunction. Interestingly, beta-blocker therapy was not associated with an increased risk. In multivariate models, arterial hypertension (OR: 6.36 [1.16-34.85]; P = .033), diabetes (OR: 7.40 [1.31-41.75]; P = .023), MELD (OR: 1.19 [1.03-1.36]; P = .015) and increasing HVPG (n = 48; OR: 1.11 [1.002-1.23]; P = .045) were independent risk factors for the presence of erectile dysfunction.ConclusionAbout two-thirds of male patients with cirrhosis show erectile dysfunction. Severity of liver dysfunction, portal hypertension, arterial hypertension and diabetes were identified as risk factors for erectile dysfunction.

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:In traditional Chinese medicine (TCM), blood stasis syndrome (BSS) is mainly manifested by the increase of blood viscosity, platelet adhesion rate and aggregation, and the change of microcirculation, resulting in vascular endothelial injury. It is an important factor in the development of diabetes mellitus (DM). The aim of this study was to screen out the potential candidate microRNAs (miRNAs) in DM patients with BSS by high-throughput sequencing (HTS) and bioinformatics analysis. CRL-1730 human umbilical vein endothelial cells (HUVECs) were incubated with 10% human serum to establish models of DM with BSS, DM without BSS (NBS) and normal control (NC). Total RNA of each sample was extracted and sequenced by the Hiseq2000 platform. Differentially expressed miRNAs (DE-miRNAs) and mRNAs (DE-mRNAs) were screened between samples. Target genes of miRNAs were predicted by softwares. Gene Ontology (GO) and pathway enrichment analysis of the target genes were conducted. According to the significantly enriched GO annotations and pathways (P value ≤0.001), we selected the key miRNAs of DM with BSS.
