Project description:L-type voltage gated Ca channels play a critical role in E-C coupling in cardiac muscle. alpha1C is associated with beta auxiliary subunits (b1-b4), which regulate cardiac Ca channel gating properties. Here we report a preliminary exploratory study suggesting a novel role of beta4 subunit in heart. We observed that overexpression of beta4 subunit increases the expression of a wide variety of endogenous genes related to antiviral activity. This includes genes in the downstream signalling of RIG-1 pathway such as RIG-1, Irf7 and Ifitm3. The increase expression of these factors may have an antiviral protective role against infection.
Project description:Mitochondrial dysfunction and excessive lipid accumulation in non-adipose tissues have been proposed widely as the roots for comorbidities generated by the growing epidemia of type 2 diabetes mellitus. Mouse models of lipotoxic cardiomyopathy have underlined this detrimental situation, but so far the proteins involved in diabetic patients’s induced mitochondrial dysfunction remain unknown. Apolipoprotein O (ApoO), originally found overexpressed in human diabetics hearts (Lamant et al. JBC 2006), is a candidate that was investigated here at the transcriptome level using H9c2 cardiomyoblasts after stable integration of an expression vector (pTT-ApoO) constitutively expressing ApoO.
Project description:Acute myocardial infarction is a leading cause of death among adults globally. Hypoxia/reoxygenation (H/R) injury plays a causal role in myocardial damage and death, whose molecular mechanisms remain largely elusive. Our present work employed rat H9C2 cardiomyocytes to establish an H/R injury model and investigated differential expression profiles following H/R treatment using RNA-seq. Normal cultured H9C2 cardiomyocytes were used as the control group.
Project description:The human HEK293 / 293T and rat cardiomyoblast H9c2 cell lines are commonly employed for microRNA-mRNA interaction studies. Here, I provide microRNA sequencing data obtained from each of these lines to better document which microRNAs are endogenously expressed at high or low levels. Small RNA sequencing profiles were generated from cultured HEK293 and H9c2 cells on Illumina HiSeq 2000 instruments.
Project description:During culture, H9c2 cells acquire a myotubule phenotype where a critical component is the inclusion of retinoic acid (RA). The results from some authors on H9c2 suggested that thousands of genes respond to RA stimuli, while other authors report hundreds of genes responding to RA over different cell types. We investigated the response to RA in H9c2 cells controlling for culture time.
Project description:We use the illumina high-throughput sequencing technology to identify miRNAs between the exosomes of H9c2 cells with or without alcohol-induced.The H9c2 cells were cultured in serum-free medium and stimulated with ethanol (100 mmol/L) or PBS for 24 h, then collected the exosomes samples from serum-free medium. Exosomes were isolated and extracted by differential centrifugation and detected by electron microscopy, particle size and related marker proteins.In total, 123 differentially expressed miRNAs (12 upregulated and 111 downregulated) were screened by miRNA sequence.
Project description:Analysis of H9C2 cells following PAGln treatment or not. PAGln regulates various mRNA expression in H9C2 cells.Results provide insight into the role of PAGln-involved mechanisms underlying PAGln-mediated effects on coronary artery disease (CAD).

Project description:To investigate the function of exosomes from cardiopulmonary progenitors in the regulation of gene expression in endothelial cells.We performed gene expression profiling analysis using data obtained from RNA-seq of H9C2 treated with or without CPPs exosomes.
