Project description:It is commonly observed that patients with bone fracture concomitated with traumatic brain injury (TBI) had significantly increased fracture healing while the underlying mechanisms were not fully revealed. Long non-coding RNAs (lncRNAs) were known for paly complicated roles in bone homeostasis while its role in TBI accelerated fracture were rarely reported. The present study was designed to determine the role of lncRNAs in TBI accelerated fracture via transcriptome sequencing and further bioinformatical analysis. Blood samples from 3 fracture only patients, 3 fracture concomitated with TIB patients and 3 healthy controls were harvested and were subsequently subjected to transcriptome lncRNAs sequencing. Differentially expression genes were identified, and pathway enrichment were performed by Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyze. High high-dimensional data portraying by self-organizing map (SOM) machine learning was applied to further interpret the data. A xCell method were then used to predict cellular behavior in all samples based on gene expression profiles and a lncRNA-cell interaction network were generated. A total of 874 differentially expressed genes were identified, of which about 26% were lncRNAs. Those identified lncRNAs were mainly enriched on traumatic brain injury related- and damage repair related-pathways. SOM analyzes revealed that those differentially expressed lncRNAs could be divided into three major module implications and were mainly enriched on transcriptional regulation and immune related signal pathways, which promote us to further explore cellular behaviors based on differentially expressed lncRNAs. We have predicted that basophils, CD8+ T effector memory cells, B cells, and naïve B cells were significantly down-regulated while microvascular endothelia cells were predicated significantly up-regulated with TBI/Fr group was the lowest or highest, respectively. ENSG00000278905, ENSG00000240980, ENSG00000255670, and ENSG00000196634 were the most differentially expression lcnRNA that related to all changes of cellular behavior. The present study has revealed for the first time that several critical lncRNAs may participate in TBI accelerated fracture potentially via regulating cellular behaviors of basophils, cytotoxic T cells, B cells and endothelia cells.

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.

Project description:The identification of the expression patterns of long non‑coding RNAs (lncRNAs) and mRNAs in the kidney under normal and renal ischemia/reperfusion (IR) conditions is essential for understanding the genetic mechanisms underlying the pathogenesis of renal IR injury. Here, we have carried out a genome-wide long non-coding RNA and mRNA microarray analysis in mice kidneys with IR. The data revealed that the expression profiles of lncRNAs and mRNAs in the kidneys differed markedly between the Sham group and IR group, and in total 276 differentially expressed (>2‑fold) lncRNAs (201 upregulated, 75 downregulated) and 267 mRNAs (192 upregulated, 75 downregulated) were identified. qRT-PCR analysis was performed to verify the expression patterns of several lncRNAs and mRNAs.We found a specific and strongly differentially expressed lncRNA, an renal ischemia-reperfusion (IR) injury associated RNA, termed lncRNA-IRAR, which was mainly located in tubular epithelia cells. In vitro and in vivo gain- or loss-of-function studies were performed to investigate the role of lncRNA-IRAR during renal IRI. Moreover, an expression volcano map of the differentially expressed mRNAs showed that UCP1 was the most dramatically downregulated gene, and its role in oxidative stress and apoptosis was assessed both in vitro and in vivo. Genetic deletion of UCP1 was used to investigate the effects of UCP1 on ischemia -indued acute kidney injury in mice.

Project description:A few reports have implicated specific lncRNAs in cardiac development or failure, but precise details of lncRNAs expressed in hearts and how their expression may be altered during embryonic heart development or by adult heart disease is unknown. By comparing lncRNA profiles of normal embryonic (~E14), normal adult, and hypertrophied adult hearts we defined a distinct fetal lncRNA abundance signature that includes 157 lncRNAs differentially expressed compared to adults (fold-change ≥ 50%, FDR=0.02), and which was only poorly recapitulated in hypertrophied hearts (17 differentially expressed lncRNAs; 13 of these observed in embryonic hearts). Analysis of protein-coding mRNAs from the same samples identified 22 concordantly and 11 reciprocally regulated mRNAs within 10 kb of dynamically expressed lncRNAs, reciprocal relationships of lncRNA and mRNA levels was validated for the Mccc1 and Relb genes using in vitro lncRNA knockdown in C2C12 cells. Network analysis suggested a central role for lncRNAs in modulating NFkappaB- and CREB1-regulated genes during embryonic heart growth and identified multiple mRNAs within these pathways that are also regulated, but independently of lncRNAs. Cardiac polyadenylated RNA (mRNA and lncRNA) profiles were generated from C57BL/6J mouse hearts were generated on Illumina HiSeq 2000 instruments. 7 independent E13.5 hearts, 12 adult hearts (6 at 6 weeks of age, 6 at 16 weeks of age), 4 sham-operated hearts at 12 weeks of age, and 4 hearts after 4 weeks of pressure overload (TAC) at 12 weeks of age.

Project description: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.

Project description:Celastrol plays a significant role in cerebral ischemia-reperfusion injury. Although previous studies have confirmed that celastrol post-treatment has a protective effect on ischemic stroke, the therapeutic effect of celastrol on ischemic stroke and the underlying molecular mechanism remain unclear. In the present study, focal transient cerebral ischemia was induced by transient middle cerebral artery occlusion (tMCAO) in mice and celastrol was administered immediately after reperfusion. We performed lncRNA and mRNA analysis in the ischemic hemisphere of adult mice with celastrol post-treatment through RNA-Sequencing (RNA-Seq). A total of 50 differentially expressed lncRNAs (DE lncRNAs) and 696 differentially expressed mRNAs (DE mRNAs) were identified between the sham and tMCAO group, and a total of 544 DE lncRNAs and 324 DE mRNAs were identified between the tMCAO and tMCAO+celastrol group. Bioinformatic analysis was done on the identified deregulated genes through gene ontology (GO) analysis, KEGG pathway analysis and network analysis. Pathway analysis indicated that inflammation-related signaling pathways played vital roles in the treatment of ischemic stroke by celastrol. Our study suggests celastrol treatment can effectively reduce cerebral ischemia-reperfusion injury. The bioinformatics analysis of lnRNAs and mRNAs profiles in the ischemic hemisphere of adult mice provides a new perspective in the neuroprotective effects of celastrol, particularly with regards to ischemic stroke.
