Project description:Rev-erbα/β are druggable components of the molecular circadian clock. Rev-erb agonists can mitigate pressure overload-induced cardiac hypertrophy and myocardial infarction in mice, while Rev-erb antagonist increases myocardial ischemia-reperfusion tolerance ex vivo at the sleep-to-wake transitionHow cardiac Rev-erb regulates heart function has not been studied in vivo. ChIP-seq of Rev-erbα in the heart confirmed the robust diurnal rhythmicity of Rev-erbα genome binding with about 5 times more binding at ZT9 than at ZT21.
Project description:In this study, we have investigated the effect of LMP2A on gene expression in normal human GC B cells using a non-viral vector based system Keywords: transfection of viral oncogene in normal human B cells Gene expression was compared between LMP2A-transfected and control vector-transfected GC B cells from three patients. RNA from the FACS-sorted transfected GC B cells was amplified. 10ug of fragmented cRNA was hybridized to HG-U133 Plus 2.0 microarrays. Differentially expressed probe sets were identified using limma with a fold change >1.3 and p < 0.01
Project description:We report for the first time movement of Correia Repeat Enclosed Elements, through inversion of the element at its chromosomal location. Analysis of Ion Torrent generated genome sequence data from Neisseria gonorrhoeae strain NCCP11945 passaged for 8 weeks in the laboratory under standard conditions and stress conditions revealed a total of 37 inversions: 24 were exclusively seen in the stressed sample; 7 in the control sample; and the remaining 3 were seen in both samples. These inversions have the capability to alter gene expression in N. gonorrhoeae through the previously determined activities of the sequence features of these elements. In addition, the locations of predicted non-coding RNAs were investigated to identify potential associations with CREE. Associations varied between strains, as did the number of each element identified. The analysis indicates a role for CREE in disrupting ancestral regulatory networks, including non-coding RNAs. RNA-Seq was used to examine expression changes related to Correia repeats in the strain
Project description:In order to determine whether dis-regulation of a genetic pathway could explain the increased apoptosis of parp-2-/- double positive thymocytes, the gene expression profiles in double positive thymocytes derived from wild-type and parp-2-/- mice were analysed using Affymetrix oligonucleotide chips (mouse genome 430 2.0).
Project description:Ossification of the posterior longitudinal ligament (OPLL) is formed by heterogeneous ossification of posterior longitudinal ligament. The patho-mechanism of OPLL is still largely unknown. MicroRNAs are small nucleatides that function as regulators of gene expression in almost any biological process. However, few microRNAs are reported to have a role in the pathological process of OPLL. Therefore, we performed high-throughput microRNA sequencing and transcriptome sequencing of primary OPLL and PLL cells in order to decipher the interacting network of microRNAs in OPLL. MRNA and microRNA profiles were done using primary culture cells of human ossification of the posterior longitudinal ligament (OPLL) tissue and normal posterior longitudinal ligament (PLL) tissue.
Project description:Human umbilical cord matrix-mesenchymal stromal cells (hUCM-MSC) have demonstrated beneficial effects in experimental acute myocardial infarction (AMI). In this study, we investigated the outcome of the delivery of hUCM-MSC after reperfusion in a translational model of AMI in swine. We have found that intracoronary injection of the cell product was associated with improved systolic function and that improvement in mechanical performance. This did not depend on the reduction of morphological infarct size alone, despite treated animals showing signs of less adverse remodeling.
