Project description:In previous studies, microcurrent electrical nerve stimulation (MENS) has been also used for pain control and muscular growth, but no literatures study the effects and mechanisms of MENS for DM management. Here we analyzed the effect of MENS and MENS mechanisms using phenotype data and omics data of mouse animal model. The results showed MENS regulated diabetes-related pathways to lower blood glucose.

Project description:Diabetes mellitus (DM) is one of the most common chronic diseases around the world, and diabetic peripheral neuropathy (DPN) is one of the most common complications of DM. We used microarrays to identify the differentially expressed miRNAs in dorsal root ganglia (DRG) tissues from streptozotocin (STZ)-induced diabetic rats, taking normal SD rats as controls, and tried to find out the related genes which may be involved in the development of DPN.

Project description:We observe morphological changes of retinal microglia during early stages of diabetic retinopathy in STZ-treated mice. Therefore, in this experiment we assess the impact of STZ-induced diabetic retinopathy on retinal microglia transcriptome during early stages of disease.

Project description:Impaired wound healing is one of the main reasons that leads to diabetic foot ulcerations. However, the exact mechanism of delayed wound healing in diabetes mellitus is not fully understood. Long non-coding RNAs (lncRNAs) are widely involved in a variety of biological processes and diseases, including diabetes and its associated complications. To further identify the roles of LncRNAs in diabetic wound healing, four STZ induced diabetic rat skin tissues and four control rat skin tissues were prepared for a LncRNAs microarray expression profiling by using rat LncRNA Array (4 x 44K, Arraystar).

Project description:Diabetes mellitus (DM) is one of the most common chronic diseases around the world, and diabetic peripheral neuropathy (DPN) is one of the most common complications of DM. We used microarrays to identify the differentially expressed lncRNAs and mRNAs in dorsal root ganglia (DRG) tissues from streptozotocin (STZ)-induced diabetic rats, taking normal SD rats as controls, and tried to find out the related genes which may be involved in the development of DPN.

Project description:The main cause of morbidity and mortality in diabetes mellitus (DM) are cardiovascular complications. Diabetic cardiomyopathy (DCM) remains incompletely understood. Animal models have been crucial in exploring DCM pathophysiology while identifying potential therapeutic targets. Streptozotocin (STZ) has been widely used to produce experimental models of both type 1 and type 2 DM (T1DM and T2DM). Here we compared these two models for their effects on cardiac structure, function, and transcriptome. Different doses of STZ and different diet chows were used to generate T1DM and T2DM in C57BL/6J mice. Normal euglycemic and non-obese sex and age-matched mice served as controls (CTRL). Immunohistochemistry, RT-PCR, and RNA-Seq were employed to compare hearts from the three animal groups. STZ-induced T1DM and T2DM differently affect left ventricular function and myocardial performance. T1DM displays an exaggerated apoptotic cardiomyocyte (CM) death and reactive hypertrophy and fibrosis along with increased cardiac oxidative stress, CM DNA damage and senescence when compared to T2DM mice. T1DM and T2DM differently affect whole cardiac transcriptome. In conclusion, STZ-induced T1DM and T2DM mouse models show significant differences in cardiac remodeling, function and whole transcriptome. These differences could be of key relevance when choosing an animal model to study specific features of DCM.

Project description:Background and Aims: It is well demonstrated that in the beta cell population of the pancreas there is a dynamic turnover, which results from the net balance of several processes; beta cell replication, apoptosis and neogenesis. These processes have been studied in partial pancreatectomy and glucagon-like peptide 1 treated animals, where an increase in pancreas regeneration has been observed. Similarly, sodium tungstate, which decreases hyperglycemia in several animal models of diabetes, promotes a rise in the beta cell mass of nSTZ and STZ animals. However, the molecular mechanisms underlying this pancreas regeneration remain unknown. Therefore the objective of this study is to identify which genes are up or down regulated in the increase of the beta cell population of STZ rats treated with sodium tungstate. Materials and methods: Adult male Wistar (225-250 g) rats were kept under a constant 12-hour light-dark cycle and rats were kept under a constant 12-hour light-dark cycle and were allowed to eat and drink freely. Diabetes was induced by a single i.p. injection of streptozotocin (STZ) (70 mg/Kg body weight) in 0.9% NaCl with 100 mmol/L sodium citrate buffer (pH 4.5). Diabetes was confirmed by determination of its hyperglycaemia (>500mg/dL [Reflotron, Roche Diagnostic]). Healthy rats received an i.p. injection of the vehicle. Treatment started 7 days after the STZ or vehicle injection. Diabetic and healthy rats were divided into two groups. In the first (untreated), rats received deionized drinking water; in the second (treated) group, they were given a solution of sodium tungstate. During the first week of treatment, the rats received a solution of 0.7 mg/mL and in the next 4-5 weeks, the concentration was increased to 2 mg/mL. At the end of the experiment, the animals were sacrificed and pancreatic RNA isolated. Three chips (Affymetrix RAE-230A) were hybridized for each of the four experimental groups (untreated and treated healthy rats and untreated and treated diabetic rats). The raw intensity data obtained from the microarrays was normalized and summarized using the Bioconductor package RMA.
