Differentially expressed messenger RNAs and long noncoding RNAs after spinal cord injury

ABSTRACT: Spinal cord injury (SCI) is a severely disastrous event that occurs in the central nervous system (CNS) that is associated with high disability and mortality rates.To further explore the expression of mRNAs and lncRNAs and the potential roles of differentially expressed mRNAs and lncRNAs after SCI, we examined the expression of mRNAs and lncRNAs in a rat model at 2 hours, 2 days and 7 days after SCI and identified the differentially expressed lncRNAs (DE lncRNAs) and differentially expressed mRNAs (DE mRNAs) using microarray analysis. A total of 992 mRNAs were differentially expressed at 2 hours after SCI, among which 730 mRNAs were up-regulated and 262 mRNAs were down-regulated. A total of 4308 mRNAs were differentially expressed at 2 days after SCI, including 2229 mRNA with up-regulated expression and 2079 mRNAs with down-regulated expression. A total of 4113 mRNAs were differentially expressed at 7 days after SCI, including 2339 up-regulated and 1774 down-regulated mRNAs. After SCI, 772 lncRNAs were differentially expressed in the 2-hour group (528 were up-regulated, 244 were downregulated) , 3193 lncRNAs were differentially expressed in the 2-day group (1332 were up-regulated, 1861 were downregulated) ,3093 lncRNAs were differentially expressed in the 7-day group (1290 were up-regulated, 1803 were downregulated) .The current study on provides novel insights into how lncRNAs and mRNAs regulate the pathogenesis of the immediate phase after SCI.

Expression profiles of long non-coding RNAs in neurogenic bladder of spinal cord injured rats: A transcriptomic analysis

Project description:Purpose: In this study, the expression profiles of lncRNAs and mRNAs were explored in the bladder tissue of SCI rats using next-generation sequencing. Methods:Twenty female Wistar rats were randomly divided into SCI 1-3 and normal control (NC) groups. The spinal cord was completely transected at the T9-T10 level to establish the SCI model. Bladder tissues were collected on days 7, 14, and 28 after the operation. The expression profiles of lncRNAs were detected by NGS. Differentially expressed lncRNAs (DELs) were chosen for qRT-PCR verification to validate the RNA sequencing results. Results: Compared with the NC group, the SCI 1-3 groups had 468, 117, and 408 DELs (fold change (FC) > 2), including 282, 38, and 201 up-regulated and 186, 79, and 207 down-regulated lncRNAs, respectively. Likewise, 6654, 2133, and 5706 mRNAs (FC > 2) were differentially expressed between SCI 1-3 and NC rats, of which 4821, 1195, and 3695 were up-regulated, and 1833, 938, and 2011 were down-regulated, respectively. Conclusions: The results revealed the expression profiles and possible roles of lncRNAs in SCI rat NB.

Among these DE lncRNAs, 17 were consistently over-regulated at 3- and 14- days after injury while 5 lncRNAs were consistently down-regulated. At 3-days after injury, 399 mRNAs were signiﬁcantly differentially expressed while two weeks after BPRA, 445 were downregulated. Among these mRNAs, 198 were consistently over-regulated, and 15 mRNAs were consistently under-regulated.

LncRNAs Landscape in the patients of primary gout by Microarray Analysis

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.

Expression Profiles of Long Non-Coding RNAs and Messenger RNAs in a Rat Model of Spinal Cord Injury

Project description:Spinal cord injury (SCI) is a serious disorder of the central nervous system with a high disability rate. Long non-coding RNAs (lncRNAs) are reported to mediate many biological processes. The aim of this study was to explore lncRNA and mRNA expression profiles and functional networks after SCI.We identified 5465 differentially expressed lncRNAs (DE lncRNAs) and 8366 differentially expressed mRNAs (DE mRNAs) in the SCI group compared with the sham group (fold change >2.0, P<0.05). Four genes were confirmed by real-time PCR which were consistent with the microarray data. GSEA analysis showed that most marked changes occurred in pathways related to immune inflammation and nerve cell function, including cytokine-cytokine receptor interaction (rno04060), TNF signaling pathway (rno04668), neuroactive ligand-receptor interaction (rno04080)，and GABAergic synapse (rno04727). Enrichment analysis identified 30 signaling pathways, including those associated with inflammation and the immune response. A total of 40 key lncRNAs were identified using the SVM-RFE algorithm. A key lncRNA-mRNAs co-expression network was generated for 230 951 lncRNA-mRNA pairs with half showing positive correlations. Several key DE lncRNAs were predicted to have “cis” or “trans”-regulated target genes. The transcription factors, Sp1, JUN, and SOX10, may regulate the interaction between XR_001837123.1 and ETS 1. In addition, five pairs of ceRNA regulatory sequences were identified.

Genome-wide analysis of long noncoding RNA and messager RNA expression in ApoE-deficient mice

Project description:Atherosclerosis is a multifactorial chronic inflammatory disease with high prevalence and has become the first reason for death worldwide. Long non-coding RNAs (lncRNAs) are non-coding RNAs with a length of >200 bp. LncRNAs participate in many biological and pathological processes such as carcinogenesis, cardiovascular diseases. The present study was designed to investigate the lncRNA and mRNA expression in the aorta of diet-induced ApoE(-/-) mice using microarray analysis. The homozygous male apoE(-/-) mice were randomly divided into two groups, with 3 animals for each group. The normal diet group was fed with normal chow, while the treated group was fed with a high-fat, high-cholesterol diet containing 20% fat and 2.5% cholesterol. The treatment duration is 8-week. After treatment, the aorta of each mouse was taken, and the lncRNA and mRNAs profiles were detected using Agilent mouse lncRNA Microarray (4*180K, Design ID: 049801) which contains 51302 lncRNAs and 39430 mRNAs. As a result, a total of 354 differentially expressed lncRNAs, including 168 up-regulated and 186 down-regulated, were identified (≥2.0 folds). Simultaneously, we also identified 357 differentially expressed protein coding mRNAs from the same chip, including 211 up-regulated 146 down-regulated mRNAs. The present study identified a panel of dysregulated lncRNAs and mRNAs that may be potential biomarkers or drug targets and correlated with the pathogenesis of atherosclerosis.
