Long non coding RNA expression in post myocardial infarction 3 days and 14 days

ABSTRACT: To explore the key lncRNAs involved in regulating essential pathophysiological processes of the adult heart, we performed microarray-based transcriptome profiling on mouse hearts 3 days and 14 days after myocardial infarction (MI) or sham surgery. Microarray analysis revealed a total of 7,339 differentially expressed transcripts in MI 3 days hearts compared to sham controls (FC≥2, p<0.05). Kyoto Encyclopedia of Genes and Genomes (KEGG) or Gene Ontology (GO) pathway analyses revealed that oxidative phosphorylation, ECM-receptor interaction, cell proliferation, and inflammatory responses were among the top dysregulated genes in MI hearts. Interestingly, 209 lncRNAs are upregulated and 543 lncRNAs are downregulated in MI 3 days hearts (FC≥2, p<0.05). Among these lncRNA transcripts, we found that 8 lncRNAs are mostly upregulated and 6 lncRNAs mostly downregulated (FC≥2, p<0.05), whereas the expression level of the AK048087 transcript was increased by 25 fold and lncRNA AK034241 appears to be the most downregulated lncRNA.

Polyadenylated RNA Sequencing of C57BL/6J Embryonic, Adult and Pressure-Overloaded Hearts

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.

mRNA Expression data from murine hearts subjected to ligation of the left anterior descending coronary artery (myocardial infarction, MI model) or sham surgery (SH)

Project description:The left anterior descending coronary artery permanent ligation model of myocardial infarction was used to study the time of day differences in genetic responses post-MI between sleep-time MI, wake-time MI, wake-sham and sleep-sham mouse hearts. The micorarray approach allows the investigation of gene expression changes of all genes in sleep-time MI vs. wake-time MI vs. sham hearts.

mRNA Expression Data from Murine Hearts of Shiftwork MI, Normal MI and Sham Wildtype Mice at 24-hours Post-MI

Project description:Male C57Bl/6 mice were randomized to undergo 5 days of i) a shiftwork protocol (10-hour light: 10-hour dark cycle) before myocardial infarction (MI) surgery, ii) a normal 12-hour light: 12-hour dark environment before MI surgery, iii) a normal 12-hour light: 12-hour dark environment and used as sham controls, or iv) a shiftwork protocol (10-hour light: 10-hour dark cycle) and used as sham controls. MI surgery was performed on the 5th day, after which all mice were returned to a normal 12-hour light: 12-hour dark cycle. Hearts were collected 24-hours post-MI at ZT06. The microarray approach allows the investigation of transcriptome-wide gene expression changes in hearts from mice on a shiftwork cycle or on a regular light:dark cycle before MI.

Differentially expressed lncRNAs in hDPSCs between the OCT4A-overexpressing and vector groups.

Project description:To determine whether lncRNAs were involved in the OCT4A-related network that regulates the self-renewal of hDPSCs, human lncRNA microarrays were used to identify the lncRNA expression profiles in OCT4A-overexpressing and vector hDPSCs. 978 lncRNAs (250 of which were upregulated and 728 downregulated) and 404 mRNAs (222 of which were upregulated and 182 downregulated) were potential differentially expressed genes (fold change≥2, P<0.05).
