| Abstract | Backgrounds: Exosomes carry various types of transcripts such as messenger RNAs (mRNAs) and play an important role in mediating cell-to-cell communication, thus influencing multiple physiological and pathological processes. However, the role of exosomal mRNAs in T1DM are largely unknown. Here, we aimed to identify the plasma-derived exosomal mRNA expression profiles in T1DM and explore their potential biological function in T1DM. Materia and Methods: Plasma-derived exosomes were isolated from 10 patients with T1DM and 10 age-, sex- matched control subjects by size exclusion chromatography methods. Transmission electron microscopy, nanoparticle tracking analysis, and western blot analysis confirmed the presence of exosomes. The exosomal mRNAs were analyzed using Illumina Hiseq platform. Six differentially expressed mRNAs (DEMs) were randomly selected to determine the expression level by quantitative real-time PCR (qRT-PCR) in a larger cohort (T1DM subjects N=40; Control subject N=40). The biological functions of DEMs were predicted by Geno Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis. The protein-protein interaction networks were constructed to explore the potential associations among DEMs. Results: Totally, 112 DEMs were identified in T1DM, among which 66 mRNAs were up-regulated and 46 mRNAs were down-regulated. Four of six candidate exosomal mRNAs were successfully validated by qRT-PCR. Bioinformatics analysis indicated that these mRNAs were most significantly involved in positive regulation by host of viral transcription (GO enrichment analysis) and oxidative phosphorylation (KEGG pathway analysis). Conclusions: Our study reported the plasma-derived exosomal mRNAs expression profile of T1DM for the first time. Identified DEMs might be associated with the pathogenesis of T1DM and some DEMs have the potential to serve as biomarker and therapeutic target for T1DM. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
