Whole-transcriptome sequencing analysis of streptozocin-induced diabetic and non-diabetic control rats

Project description:Diabetes mellitus is a complex metabolic disorder. Long-term hyperglycemia may induce diabetic keratopathy, which is mainly characterized by decreased tear secretion, damaged innervation, weakened cell junctions, and impaired wound healing responses. To investigate the differential expressed genes in the regulation of diabetic keratopathy, we established streptozocin-induced diabetic and non-diabetic control male Brown Norway rats. Total RNA was extracted from the corneal epithelium rats, and were subjected to whole-transcriptome sequencing analysis. Firstly, Cutadapt was used to remove the reads that contained adaptor contamination, low quality bases and undetermined bases. Then sequence quality was verified using FastQC(http://www.bioinformatics.babraham.ac.uk/projects/fastqc/). We used Bowtie2 and Hisat2to map reads to the genome from corneal epithelium of streptozocin-induced diabetic and non-diabetic control rats. The mapped reads of each sample were assembled using String Tie. Then, all transcriptomes from corneal epithelium Samples were merged to reconstruct a comprehensive transcriptome using perl scripts. We then performed gene expression profiling analysis using data obtained from RNA-seq of 6 corneas from STZ-induced diabetic rats and 6 corneas from normal controls.

DNA array analysis in OLETF, a type 2 diabetic rats, and LETO, a non-diabetic control rats

Project description:AMP deaminase (AMPD) plays a crucial role in adenine nucleotide metabolism, and its upregulated activity contributes to diastolic dysfunction of the heart caused by type 2 diabetes mellitus (T2DM) via reduction of the adenine nucleotide pool. Here we examined the mechanism of AMPD upregulation by T2DM. The protein level of 90-kDa full-length AMPD3 was increased in whole myocardial lysates and in the sarcoplasmic reticulum (SR) fraction by 55% and 123%, respectively, in OLETF, a rat model of T2DM, compared to those in LETO, a non-diabetic control, though AMPD mRNA level was unchanged in OLETF. MicroRNA array analysis revealed downregulation (>50%) of 57 microRNAs in OLETF compared to those in LETO, among which miR-301b was predicted to interact with the 3’UTR of AMPD3 mRNA. The 90-kDa AMPD3 level was significantly increased by miR-301b inhibitor, but decreased by a miR-301b mimetic in H9c2 cells. A luciferase reporter assay indicated binding of miR-301b to the 3’UTR of AMPD3 mRNA. The results indicate that translational regulation by miR-301b mediates AMPD3 upregulation in the diabetic heart. Since ATP generated by SR-associated glycolytic enzymes contributes to Ca2+ uptake by SERCA2a, upregulated AMPD3 in the vicinity of the SR may be a therapeutic target for diabetic cardiomyopathy.

Analysis of altered miRNA expression profiles in the streptozotocin-induced diabetic rats compared to normal SD rats

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.
