Project description:TK2 deficiency causes severe mtDNA depeltion in several tissues, including skeletal muscle and heart. TK2 knockout mice grow slower and their skeletal muscles appeared significantly underdeveloped, whereas heart was close to normal size. We used microarrays in order to compare the transcriptomes in skeletal muscle and heart tissue of 11 days-old TK2 knockout pups with the sames tissues of wild-type pups at the same age. We collected skeletal muscle from the hind limb and hearts of three 11 days-old TK2 knockout and three wild-type pups and extracted total RNA. These RNA samples were used for hybridization in Affymetrix arrays.

Project description:Taurine is the most abundant free amino acid in heart muscle and protects against heart failure. In the present study, the consequences of hereditary taurine deficiency on cardiac gene expression were examined in 2 and 15-16 months old taurine transporter knockout (taut-/-) mice by using a mouse-specific DNA oligonucleotide microarray which was developed with probes for 251 genes with relevance for heart. Keywords: Comparison, knock out, wildtype

Project description:Fibrosis is defined as an abnormal matrix remodeling and loss of tissue homeostasis due to excessive synthesis and accumulation of extracellular matrix proteins in tissues. At present, there is no effective therapy for organ fibrosis. Previous studies demonstrated that aged plasminogen activator inhibitor-1(PAI-1) knockout mice develop spontaneously cardiac-selective fibrosis without affecting any other organs including kidney. Therefore, the PAI-1 knockout model of cardiac fibrosis provides an excellent opportunity to find the igniter(s) of cardiac fibrosis and its status in unaffected organs. We hypothesized that differential expressions of profibrotic and antifibrotic genes in PAI-1 knockout hearts and unaffected organs lead to cardiac selective fibrosis. In order to address this prediction, we have used a genome-wide gene expression profiling of transcripts derived from aged PAI-1 knockout hearts and kidneys. The variations of global gene expression profiling were compared within four groups: wildtype heart vs. knockout heart; wildtype kidney vs. knockout kidney; knockout heart vs. knockout kidney and wildtype heart vs. wildtype kidney. Analysis of illumina-based microarray data revealed that several genes involved in different biological processes such as immune system processing, response to stress, cytokine signaling, cell proliferation, adhesion, migration, matrix organization and transcriptional regulation were affected in hearts and kidneys by the absence of PAI-1, a potent inhibitor of urokinase- and tissue-type plasminogen activator. Importantly, the expressions of a number of genes, involved in profibrotic pathways were upregulated or downregulated in PAI-1 knockout hearts compared to wildtype hearts and PAI-1 knockout kidneys. To our knowledge, this is the first comprehensive report on the influence of PAI-1 on global gene expression profiling in the heart and kidney and its implication in several biological processes including fibrogenesis. Total RNA was extracted from hearts and kidneys derived from three PAI-1 knockout (12- month old) and three wild-type mice (12-month old) using RNeasy Fibrous Tissue Mini Kit (Qiagen, Valencia, CA) following the manufacturer’s instructions. The quality of RNA (RNA Integrity, RIN) in all 12 samples (3 wildtype hearts; 3 PAI-1 KO hearts; 3 wildtype kidneys; and 3 PAI-1 KO kidneys) was checked using the bioanalyzer. We have used a genome-wide gene expression profiling of transcripts derived from aged PAI-1 knockout hearts and kidneys. The variations of global gene expression profiling were compared within four groups: wildtype heart vs. knockout heart; wildtype kidney vs. knockout kidney; knockout heart vs. knockout kidney and wildtype heart vs. wildtype kidney.

Project description:Mice without cardiac Bmal1 function develop severe progressive heart failure with age. To examine the mechanism underlying the failing heart phenotype observed in heart-specific Bmal1 knockout mice, microarray analyses were performed. The analyses revealed that broad classes of genes regulating cellular energy metabolism were upregulated or downregulated in the heart tissues of heart-specific Bmal1 knockout mice compared with those of control animals. Heart total RNA extracted from six animals per genotype (control and heart-specific Bmal1 knockout) was pooled and then used for a microarray analysis.
