Project description:To explore whether tau-related epigenomic changes that we found human brain H3K9ac data (Synapse ID: syn4896408) are recapitulated in mouse models known to accumulate tau, we generated hippocampal H3K9ac ChIP-seq profiles from two different mouse models each at an early and a late stage of neurodegeneration. Specifically, we studied 6 and 11 months old mutant tau mice (MAPT P301S), which start to accumulate phosphorylated tau in neurons by 6 months. Wild-type mice of the same age were used as controls. The second mouse model was the CK-p25 model, which is characterized by increased amyloid-β levels early after p25 induction followed by increased tau phosphorylation and neuronal loss at later stages. Three months old CK-p25 mice were studied 2 weeks and 6 weeks after p25 induction and compared with CK littermate controls.
Project description:au08-05_p25ind - comparison between constitutive and inducible p25 plants - Are there some genes deregulated by the p25 viral protein. - Comparison between constitutive and inducible p25 plants. Keywords: gene knock in (transgenic)
Project description:Alzheimer's disease (AD) is a neurodegenerative disease and is the most common form of dementia, cognitive dysfunction is a pre-AD manifestation, followed by progressive deterioration in behavior and mood, CK has good pharmacological activity, inhibit neuronal damage associated with Aβ and improve learning memory in mice through its antioxidative properties. We used microarrays to detail the regulation of brain tissue genes in cognitively impaired mice by ginsenoside CK.
Project description:Hemagglutinin of the influenza virus is the main external glycoprotein. This very immunogenic protein is the target of the most anti-influenza vaccines. DNA vaccines are new alternative to conventional inactivated ones. Four DNA vaccines were tested. Each tested variant was based on the pCI vector with nucleotide sequence encoding hemagglutinin from A/swan/Poland/305-135V08/2006 (H5N1, clade 2.2). In K3/pCI, GK/pCI and HAneo/pCI the different optimization algorithms of hemagglutinin encoding sequence without amino acids change were tested. In 3NF/pCI the NFkappaB binding sites flanking the expression cassette were included in order to improve the nuclear transfer. Comparative transcriptome analysis of mice vaccinated the following vaccine HAneo/pCI,K3/pCI, GK/pCI or 3NF/pCI versus empty vector demonstrated minor changes in genes expression pattern. Most genes were expressed on the similar level in the vaccinated individuals and in the control mice. Small number of genes in particular variants showed the expression different than in the control mice. In general, the identified genes with the changed expression included some genes involved in metabolic processes and none of them seem to induce any undesirable pathways nor disease.
Project description:We collected whole genome testis expression data from hybrid zone mice. We integrated GWAS mapping of testis expression traits and low testis weight to gain insight into the genetic basis of hybrid male sterility.
