Background: Gq-coupled G protein-coupled receptors (GPCR) mediate the actions of a variety of messengers that are key regulators of cardiovascular function. Enhanced Gaq-mediated signaling plays an important role in cardiac hypertrophy and in the transition to heart failure. We have recently described that Gaq acts as an adaptor protein that facilitates PKCz-mediated activation of ERK5 in epithelial cells. Since the ERK5 cascade is known to be involved in cardiac hypertrophy, we have investigated the potential relevance of this pathway in Gq-dependent signaling in cardiac cells.

View SamplesWe used Affymetrix microarrays to investigate gene expression changes in PBMCs isolated from male patients ongoing secondary prevention of CVD to determine significant modulatory effects that may have been induced by the intake of an initial dose of 8 mg of resveratrol-enriched grape extract for 6 months and then, 16 mg for a further 6 months.
One-year supplementation with a grape extract containing resveratrol modulates inflammatory-related microRNAs and cytokines expression in peripheral blood mononuclear cells of type 2 diabetes and hypertensive patients with coronary artery disease.

View SamplesRecent studies suggest the potential involvement of common antigenic stimuli on the ontogeny of monoclonal TCRalphabeta+/CD4+/NKa+/CD8-/+dim T-large granular lymphocyte (LGL) lymphocytosis. Since healthy individuals show (oligo)clonal expansions of hCMV-specific TCRVbeta+/CD4+/cytotoxic/memory T-cells, we investigate the potential involvement of hCMV in the origin and/or expansion of monoclonal CD4+ T-LGL. A detailed characterization of those genes that underwent changes in T-LGL cells responding to hCMV was performed by microarray gene expression profile (GEP) analysis.

View SamplesRNA-sequencing was conducted to profile the transcriptome of the post-ischemic mouse cortex at multiple reperfusion time-points. RNA was isolated from sham and middle cerebral artery occlusion (MCAO)-operated mice at different reperfusion time points (6 h, 12 h or 24 h; three independent biological replicates per group), converted into cDNA libraries, and used for Illumina deep sequencing on a NexSeq500 instrument. The sequencing reads that passed quality filters were analyzed at the transcript isoform level based on the Tuxedo software package. On average 40.6 million reads were obtained from each sample and genome mapping was on average 82.9% for all samples. We detected 20,748 genes and 56,586 isoforms in the sham group; 22,192 genes and 60,023 isoforms in the 6 h group; 21,771 genes and 59,539 isoforms in the 12 h group; and 21,576 genes and 59,020 isoforms in the 24 h group. Our study represents the first detailed analysis of post-stroke mouse cortex transcriptomes generated using RNA-sequencing technology. Overall design: Genome-wide transcriptomic profiles of healthy and post-ischemic mouse cortices at various reperfusion time-points (6 h, 12 h, or 24 h) were generated using Illumina sequencing.
