Targeting vascular endothelial growth factor (VEGF) is a common treatment strategy for neovascular eye disease, a major cause of vision loss in diabetic retinopathy and age-related macular degeneration. However, the decline in clinical efficacy over time in many patients suggests that monotherapy of anti-VEGF protein therapeutics may benefit from adjunctive treatments. Our previous work has shown that through decreased activation of the cytoskeletal protein paxillin, growth factor-induced ischemic retinopathy in the murine oxygen-induced retinopathy model could be inhibited...

Diabetes mellitus affects 9% of the adult population worldwide and the economic burden of the disease is growing exponentially. In type 2 diabetes mellitus (T2DM), when life style interventions fail to achieve treatment targets, oral antidiabetic drugs are prescribed to improve glycemic control. Several new oral antidiabetics have been launched in the last few years, which enlarged the spectrum of available treatment options in T2DM. The present study aimed to examine T2DM treatment patterns in a cohort of 7769 patients recruited from the Diabetes Registry Tyrol (DRT) with at least one visit from 2012-2015...

Purpose: In diabetes, pancreatic beta cell mass declines significantly prior to onset of fasting hyperglycemia. This decline may be due to endoplasmic reticulum (ER) stress, and the system L amino acid transporter LAT1 may be a biomarker of this process. In this study, we used 5-(2- (18)F-fluoroethoxy)-L-tryptophan ( (18)F-L-FEHTP) to target LAT1 as a potential biomarker of beta cell function in diabetes. Procedures: Uptake of (18)F-L-FEHTP was determined in wild-type C57BL/6 mice by ex vivo biodistribution...

Maternal diabetes is one of major causes of congenital malformations in offspring, but the underlying mechanism is still unclear. MiRNAs play an important role in transcriptional and post-transcriptional regulation of gene expression. However, no miRNA expression profiling of hyperglycemic offspring are thus far available. Female mice were made diabetic with streptozotocin, treated with slow-release insulin tablets, and mated. MiRNA expression profiling with Next Generation Sequencing on the SOLiD5 platform was performed on 8 control and 5 hyperglycemic embryonic day (ED)8...

Preeclampsia (PE), a hypertensive disorder of pregnancy, is increasing as a major contributor to perinatal and long-term morbidity of mother and offspring. PE is thought to originate from ischemic insults in the placenta driving the release of pro-hypertensive anti-angiogenic (sFlt-1) and pro-inflammatory (TNFα) factors into the maternal circulation. While the increased incidence of PE is hypothesized to be largely due to the obesity pandemic, the mechanisms whereby obesity increases this risk are unknown...

A synergy of a pre-accumulated genes with an autoimmunity advancing to slow abolition of pancreatic beta-cells causes insulin deficiency and results enrooting insulin dependent diabetes mellitus (IDDM). As per WHO data worldwide about 150 million people are diabetic and the number may rise to more than double by the year 2025. Any absolute cure for IDDM is not available yet, and one of the credible advent in the field include cell-based therapy. At this conjecture, mesenchymal stem cells (MSC) seems to have a specific and beneficial characteristics due to their in vivo as well as in vitro potential to mimic a pancreatic endocrine phenotype and immune-regulatory actions...

A 40-year-old male with a long-standing history of type 1 diabetes with end-stage renal failure underwent combined kidney-pancreas (KP) transplant from a standard criteria donor. Post-operative course was uncomplicated with good primary function of both transplant grafts. Induction was with thymoglobulin and maintenance immunosuppression was with tacrolimus, mycophenolate mofetil and prednisolone. Nine weeks post-transplant, the patient developed dysfunction of both grafts. Panel reactive antibody testing revealed that the patient had developed a de novo donor-specific antibody and considering an antibody-mediated rejection the patient was treated with intravenous pulse methyl prednisone 500 mg ×3 doses, IV immunoglobulin 2 mg/kg in two divided doses, and ATG 7 mg/kg (total dose of 700 mg)...

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...

OBJECTIVE: Peroxisome proliferator-activated receptor γ (PPARγ) agonists have been shown to have anti-proliferative, anti-angiogenic, and proapoptotic effects, leading to interest in their use as cancer therapeutics. Pioglitazone, a U.S. Food and Drug Administration-approved type II diabetes medication and PPARγ agonist, may have a role in adjuvant head-and-neck squamous cell carcinoma treatment or prevention. Therefore, the purpose of this study was: 1) to treat oral cavity cancer cells with the PPARγ activator, pioglitazone, to analyze gene expression changes; and 2) to compare those changes with our preexisting genomic data for development of hypothesis-driven additional basic and clinical studies...

High on-aspirin platelet reactivity (HAPR) has been associated with compromised aspirin efficacy in patients with diabetes suffering from acute cardiovascular events, but the key mechanisms remain elusive. The objective of this study was to uncover the potential link between pathogenic accumulation of salicylic acid (SA), the major metabolite of aspirin, and HAPR in diabetic state. Aspirin failed to inhibit platelet CD62P expression and thromboxane (TX) B2/6-keto-prostaglandin(PG)F1α ratio in a type 2 diabetes mellitus (T2DM) mice model, particularly in the female, which were unanimously accompanied by significantly higher plasma SA concentrations...

Plastid-made biopharmaceuticals treat major metabolic or genetic disorders, including Alzheimer's, diabetes, hypertension, hemophilia, and retinopathy. Booster vaccines made in chloroplasts prevent global infectious diseases, such as tuberculosis, malaria, cholera, and polio, and biological threats, such as anthrax and plague. Recent advances in this field include commercial-scale production of human therapeutic proteins in FDA-approved cGMP facilities, development of tags to deliver protein drugs to targeted human cells or tissues, methods to deliver precise doses, and long-term stability of protein drugs at ambient temperature, maintaining their efficacy...

BACKGROUND: Xenogeneic islet transplantation is an emerging therapeutic option for diabetic patients. However, immunological tolerance to xenogeneic islets remains a challenge. METHODS: The current study used a pig-to-mouse discordant xenogeneic islet transplant model to examine anti-donor xenogeneic immune responses during early and late rejection, and to determine experimental therapeutic interventions that promote durable pig islet xenograft survival. RESULTS: We found that during early acute rejection of pig islet xenografts, the rejecting hosts exhibited a heavy graft infiltration with B220 B cells and a robust anti-pig antibody production...

BACKGROUND: Several studies showed Type 2 Diabetes Mellitus (T2DM) to be associated with worse adverse clinical outcomes compared to non-T2DM (NDM) following Percutaneous Coronary Intervention (PCI). In addition, patients with insulin-treated T2DM (ITDM) showed worse clinical outcomes compared to patients with non-insulin treated T2DM (NITDM). Since NITDM and NDM have seldom been systematically analyzed, this study aimed to compare the short and long term adverse clinical outcomes observed in patients with NITDM and patients without T2DM following PCI...

Diabetes-associated cognitive decline (DACD) is a brain injury induced by diabetes mellitus, with cognitive impairment as the major symptom. Growing evidence has revealed that DACD is correlated with disruptions in synapses involved in cognition. Within synapses, more specifically in areas of postsynaptic density (PSD), there is a high concentration of proteins that receive and transduce synaptic information. In the present study, to identify the differentially expressed PSD proteins among DACD mice, ZiBuPiYin recipe (ZBPYR)-treated DACD mice and control mice, we applied isobaric tags for relative and absolute quantitation (iTRAQ) with LC-MS/MS technology, by which three biological replicates and three technical replicates were examined...

BACKGROUND AND OBJECTIVE: Tuberculosis (TB) risk might be increased in patients with diabetes by factors other than hyperglycaemia, such as dyslipidaemia. Host lipids are essential energy sources used by mycobacteria to persist in a latent TB state. A potential therapy targeting cholesterol catabolism of mycobacteria has been proposed, but the potential of cholesterol-lowering drugs as anti-TB therapy is unclear. The purpose of this study was to determine the effects of ezetimibe, a 2-azetidinone cholesterol absorption inhibitor, on intracellular mycobacteria survival and dormancy...
