Project description:To evaluate whether TB infections are associated with any lncRNA signatures in humans, we therefore used human lncRNAs microarray and hierarchical clustering analyses to compare lncRNAs expression in active TB patients and healthy controls. From 15,683 denoted lncRNAs, 5076 lncRNAs were identified to be differentially expressed (TB/HC > 2 or TB/HC< 0.5) in peripheral blood mononuclear cells (PBMCs) between TB and healthy subjects.

Project description:Long non-coding RNAs (lncRNAs) have been identified in various tissues and cell types from human, monkey, porcine and mouse. However, expression profile of lncRNAs across Guangxi native cattle and swamp buffalo muscle development has never been investigated. Here, we examine the expression of lncRNA in cattle and buffalo muscle at adult stage(12 months), exhibiting the first report of lncRNA in the Guangxi native cattle and swamp buffalo muscle development of a large animal. 16,236 lncRNA candidates were obtained from buffalo skeletal muscle samples, of which a number of lncRNAs were highly abundant, and 2,161 lncRNAs were differentially expressed between buffalo and cattle. Real-time quantitative PCR (qPCR) analysis confirmed the expression profile of these lncRNAs, including several highly abundant lncRNAs, and a subset of differently expressed lncRNAs according to the high-throughput RNA sequencing (RNA-seq) data. These results indicate that abundant lncRNA is differentially expressed in bovine muscle, indicating important and diverse functions in mammalian muscle development.

Project description:The degeneration of cartilage endplate in cervical disc is considered as a basis of cervical spondylosis. Owing to the important role of post-transcriptional gene regulation in phenotypes and functions of cells, non-coding ribonucleic acid (ncRNA) molecules contributed to the regulation.Degenerated cervical vertebral endplate cartilage specimens were collected from patients with cervical intervertebral disc degeneration (CIDD) that suffered from cervical spondylosis myelopathy, who had received anterior cervical discectomy and fusion (ACDF). CE specimens of healthy subjects were obtained from patients with a cervical fracture who received ACDF at The Second Affiliated Hospital of Nanchang University (Nanchang, China) and adopted SBC human ceRNA array V1.0（4×180K）. The results revealed that expressions of369 lncRNAs, 246 mRNAs, 578 circRNAs were different between degenerated cartilage endplate and healthy cartilage endplate. The functions of differentially expressed lncRNAs and co-expressed potential targeting genes were predicted by analyzing Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) biological pathway analysis. Furthermore, we analyzed and find the co-expression and interaction patterns of different RNAs and possible ceRNA mechanism. The present study provided a systematic perspective on the potential function of non-coding RNAs (ncRNAs) in the degeneration of cartilage endplate in CIDD.

Project description:To determine the expression profile and clinical significance of long non-coding RNAs (lncRNAs) in peripheral blood mononuclear cells (PBMCs) of patients with primary gout and healthy control subjects. Human lncRNA microarrays were used to identify the differentially expressed lncRNAs and mRNAs in primary gout (n=6) and healthy subjects (n=6). Bioinformatics analyses were performed to predict the roles of differently expressed lncRNAs and mRNAs. Quantitative real-time polymerase chain reaction (qRT-PCR) was applied to validate the results in 64 gout patients, and 32 healthy control subjects (HC). The microarray analysis identified 1479 differentially expressed lncRNAs (879 up-regulated and 600 down-regulated), 862 differentially expressed mRNAs (390 up-regulated and 472 down-regulated) in primary gout (fold change>2, P<0.05), respectively. The bioinformatic analysis indicated that the differentially expressed lncRNAs regulated the abnormally expressed mRNAs, which were involved in the pathogenesis of gout through several different pathways. Significant association was observed between these lncRNAs and the Clinical inflammation indicators and lipid metabolism indicators. Our results provide novel insight into the mechanisms of primary gout, and reveal that ENST00000566457 and NR-026756 could effectively discriminate the gout group and the healthy control groups.

Project description:Idiopathic short stature is diagnosed by a standing height of less than two standard deviation scores in a specific population adjusted for age and gender and the exclusion of identifiable diseases. A series of studies have confirmed that noncoding RNAs can regulate the chondrocyte proliferation, hypertrophy, and endochondral ossification in the growth plate. In order to analyze and find differentially expressed ceRNAs (lncRNAs, circRNAs and mRNAs in peripheral blood exosomes of idiopathic short stature and healthy controls, we aimed to explore whether differentially expressed ceRNAs (lncRNAs, circRNAs and mRNAs) in peripheral blood exosomes of idiopathic short stature. Three pairs of peripheral blood exosomes samples were subjected to microarray analysis using the SBC human ceRNA Microarray.

Project description:long non-coding RNAs (lncRNAs) are novel non-coding RNAs which play an important part in regulating gene transcription and translation, modulating protein function, and acting as competing endogeneous RNA. Moveover, there is increasing evidence showing that aberrant expressions of lncRNAs are implicated in various cancers. Yet, their roles in systemic lupus erythematosus (SLE), a prototypical autoimmune disease, remain unknown. To reveal the implications of LncRNAs in SLE, we used Human LncRNA Array v3.0 microarrays to measure the expression profiles of lncRNAs in T cells of patients with SLE and healthy controls. we found 869 upregulated lncRNAs and 1066 downregulated lncRNAs in SLE patients compared with controls. Coding-non-coding gene coexpression (CNC) network was constructed based on the correlation analysis between the differentially expressed lncRNA and mRNA. Downregulation of two lncRNAs, uc001ykl.1 and ENST00000448942 was established using Real-time quantitative PCR. These results showed abrrant expression profiles of lncRNAs in T cells of SLE patients and revealed their potential role in SLE.

Project description:Cardiovascular disease (CVD) is the leading cause of human morbidity and mortality worldwide, underscoring the need to improve diagnostic strategies. Monocytes play a major role in the initiation, propagation, and progression of CVD. MicroRNAs are endogenous small non-coding RNAs that control gene expression and are expressed in a tissue and disease-specific manner. Therefore they have been proposed to be useful biomarkers. The aim of this study was to investigate whether differences in miRNA expression levels in monocytes can be found (i) between patients with premature CVD and healthy controls, (ii) within healthy controls after and before aspirin and statin administration, and (iii) between current, former and non smokers.

Project description:Coronary artery disease (CAD) is the leading cause of human morbidity and mortality worldwide, underscoring the need to improve diagnostic strategies. Platelets play a major role, not only in the process of acute thrombosis during plaque rupture, but also in the formation of atherosclerosis itself. MicroRNAs are endogenous small non-coding RNAs that control gene expression and are expressed in a tissue and disease-specific manner. Therefore they have been proposed to be useful biomarkers. The aim of this study was to investigate whether differences in miRNA expression levels in platelets can be found (i) between patients with premature CAD and healthy controls and (ii) within healthy controls after and before aspirin and statin administration.

Project description:Noncoding RNAs include small transcripts, such as microRNAs and piwi-interacting RNAs, and a wide range of long noncoding RNAs (lncRNAs). Although many lncRNAs have been identified, only a small number of lncRNAs have been characterized functionally. Here, we sought to identify lncRNAs differentially expressed during replicative senescence. We compared lncRNAs expressed in proliferating, early-passage, 'young' human diploid WI-38 fibroblasts [population doubling (PDL) 20] with those expressed in senescent, late-passage, 'old' fibroblasts (PDL 52) by RNA sequencing (RNA-Seq). Numerous transcripts in all lncRNA groups (antisense lncRNAs, pseudogene-encoded lncRNAs, previously described lncRNAs and novel lncRNAs) were validated using reverse transcription (RT) and real-time, quantitative (q)PCR. Among the novel senescence-associated lncRNAs (SAL-RNAs) showing lower abundance in senescent cells, SAL-RNA1 (XLOC_023166) was found to delay senescence, because reducing SAL-RNA1 levels enhanced the appearance of phenotypic traits of senescence, including an enlarged morphology, positive β-galactosidase activity, and heightened p53 levels. Our results reveal that the expression of known and novel lncRNAs changes with senescence and suggests that SAL-RNAs play direct regulatory roles in this important cellular process. RNA was extracted from both young and senescent WI-38 cells and used for total RNA-Seq.
