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

ABSTRACT: 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.

Global analysis of plasma lipidomics reveals altered lipid signatures in patients with osteonecrosis of the femoral head

Project description:AIMS: Although studies have made the connection between lipid metabolism disorder and osteonecrosis of the femoral head (ONFH), the characteristics of the circulating lipidome signature of ONFH have not yet been investigated yet and need to be explored.METHODS: We conducted a comprehensive analysis of plasma lipidomics in a clinical human cohort including 32 healthy normal control (NC) subjects and 91 ONFH patients in different subgroups (alcohol-induced [AONFH], steroid-induced, and traumatic ONFH) and stages (stages I/II, stages III/IV), using ultra-high performance liquid chromatography–tandem mass spectrometry.RESULTS: The PLS-DA model indicates that the global plasma lipidome profile differs between the ONFH and NC samples. We identified a signature including 22 common differentially expressed lipids (DELs) in all the three subgroups (VIP > 1, P < 0.05, FC > 1.5 or FC < 0.67, compared with the NC group), and for each of the subtype-specific lipidome profiles, as well as altered lipid biomarkers (FC > 2, P < 0.05, and AUC > 0.7, compared with the NC group) for each subgroup. The AONFH subgroup has the most DELs, and the plasma levels of lipid compounds in the subclass of triacylglycerol increased obviously in the AONFH samples. We identified that 9 stage-positive and 2 stage-negative lipids may function as novel biomarkers that predict the disease progression of ONFH.CONCLUSION: This study provides the first overview, analysis, and understanding of the unique phenotype-related plasma lipidome signature of ONFH. The results will offer insights into the mechanisms underlying lipid metabolism in the pathogenesis and progression of ONFH, and will help to identify novel lipids biomarkers or targets for disease diagnosis and treatment.

Urinary bladder post-spinal cord injury: time-points

Project description:Previously, we demonstrated using a rat model of spinal cord injury (SCI) that bladder wall tissue compliance significantly increased within the first 2 weeks following injury. In order to explore the potential molecular-level mechanisms of this event, the present study quantified molecules pertinent to bladder tissue remodeling and changes in mechanical properties. An initial gene array analysis followed by real-time qPCR revealed that the message levels for tropoelastin and lysyl oxidase were as high as 8-fold in SCI rats compared to normal. Furthermore, both the message and protein levels of TGF-beta1 and IGF-1, known stimulators of elastin synthesis, in SCI rat bladders were significantly higher compared to those of normal rats. Taken together, it can be speculated that functional changes of the bladder associated with SCI induce release of select growth factors, which, in turn, stimulate elastogenesis that lead to alteration of biomechanical properties of the wall tissue.

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

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.

Transcriptome sequencing analysis of lncRNA and mRNA expression profiles in bone nonunion

Project description:Background: Bone nonunion is a serious complication of fracture. This study explored the differentially expressed lncRNAs (DELs) and mRNAs (DEGs) and identified potential lncRNA-mRNA interactions in bone nonunion. Methods: We extracted total RNA from three bone nonunion and three bone union patient tissue samples. RNA sequencing was performed to detect DELs and DEGs between bone nonunion and union tissue samples. The lncRNAs and genes with absolute log2-fold change (log2FC) > 1 and adjusted p value < 0.05 were further chosen for gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. lncRNA and targeted mRNA interaction networks were constructed. Results: We observed 179 DELs and 415 DEGs between the bone nonunion and union tissue samples. GO analysis indicated that DELs and DEGs were mainly enriched in chondroitin sulfate proteoglycan biosynthetic process. DELs and DEGs were enriched in 'ECM-receptor interaction' and 'Staphylococcus aureus infection' KEGG pathways. Several potential lncRNA-mRNA interactions were also predicted. Conclusions: This study identified bone nonunion-associated lncRNAs and mRNAs using deep sequencing that may be useful as potential biomarkers for bone nonunion.

Genome-wide characterization of lncRNAs and mRNAs in muscles with differential meat quality

Project description:Meat quality is one of the most important traits in pig production. Long non-coding RNAs (lncRNAs) has been involved in diverse biological processes such as muscle development through regulating gene expression. However, studies on lncRNAs lag behind and a comparatively small number of lncRNAs have been identified in pigs. Also, effects of lncRNAs on meat quality remains to be characterized. Here, we analyzed lncRNAs in longissimus thoracis (LT) and semitendinosus (ST) muscles, being different in meat quality, with RNA-sequencing technology. A total of 500 differentially expressed lncRNAs (DELs) and 2094 protein-coding genes (DEGs) were identified. Through KEGG analysis on DELs we first made clear that fat deposition might be the main reason resulting in differential phenotype of LT and ST, on the basis of which 41 key DELs and 50 DEGs involved in differential fat deposition were characterized. One of the key genes, cAMP-response element binding protein 1, was selected to confirm its role in porcine adipogenesis with molecular biology methods and found that it promotes the differentiation of porcine preadipocytes, consistent with its higher expression level and intramuscular fat contents in LT than that in ST muscle. Furthermore, through integrated analysis of DELs and DEGs, transcription factors important for differential fat deposition were characterized among which BCL6 have the most target DEGs while MEF2A was targeted by the most DELs. The results provide candidate genes crucial for meat quality, which will contribute to revealing the molecular mechanisms underlying meat quality

The effects of herb-partitioned moxibustion on miRNA expression profiling in the colons of CD rats

Project description:Using the highly sensitive miRNA microarray, we screened differentially-expressed miRNAs in colons of normal control (NC) rats, model control (MC) rats and herb-partitioned moxibustion (HPM) rats. We found 40 miRNAs differentially expressed in CD rats’ colons compared with the NC rats, and HPM significantly regulated 26 miRNAs in colon tissues compared with the MC group. Furthermore, the quantitative real-time polymerase chain reaction results showed that down-regulated miR-147 and miR-205 in CD rats’ colons were both significantly up-regulated by HPM, with 2.64- and 3.72-folds increased respectively, indicating that miR-147 and miR-205 are the target genes of HPM in treating CD rats.

miRNA-seq in human lung cancer tissues

Project description:we conducted transcriptome and small RNA sequencing to identify differentially expressed genes (DEGs), miRNAs (DEMs), and lncRNAs (DELs). Function analysis on DEM-target genes can explain the regulatory roles of miRNAs in LC. The lncRNA-miRNA pairs, miRNA-mRNA pairs, and lncRNA-mRNA pairs were identified, which were then combined to construct the interplay of lncRNAs/miRNAs/mRNAs. And we used the online databases to verify the selected DEMs, DELs, and DEGs. Our study identified 2509 DEGs, 34 DEMs, and 432 DELs in LC patients. miRNA-mRNA pairs, including 1 miRNA (hsa-miR-21-5p) and 5 targeted genes (RECK, TIMP3, EHD1, RASGRP1 and ERG), were figured out. We finally found the hub subnetwork (LINC00632/has-miR-21-5p/TIMP3) by combining lncRNA-miRNA pairs, miRNA-mRNA pairs and lncRNA-mRNA pairs.
