Project description:Patients with epilepsy often experience increased frequency of seizures at night. Given the crucial role glial cells play in modulating neuronal excitability, we hypothesize that circadian changes in glia may affect changes in seizure threshold. Fatty acid binding protein 7 (Fabp7) is expressed in brain astrocytes and is involved in the transport of fatty acids, signal transduction, and gene transcription. Its mRNA expression levels rise and fall in a circadian rhythm and is necessary for normal sleep regulation. We examined if Fabp7 influences electrically induced seizure threshold and differential gene expression in wild type (WT) vs. Fabp7 knockout (KO) mice with and without seizure.
Project description:To discover the molecules and signal pathways that are associated with the anti-aging effects of Fabp7 deficiency, transcriptome analyses were conducted using DNA microarray. The ABR thresholds of Fabp7 (+/+) and Fabp7 (-/-) mice were not significantly different at 7 months of age, but it was speculated that important gene expression changes might arise at approximately this stage. Therefore, 7-month-old Fabp7 (+/+) and Fabp7 (-/-) mice were used for transcriptome analyses.
Project description:We demonstrated that Wnt/β-catenin pathway was activated in in endotoxemic mice, and the modulation of this pathway by LGK974 had beneficial effects by suppressing the inflammation and lethality caused by endotoxemia.
Project description:Liver has a crucial role in the regulation of immune defense in systemic infections. During endotoxemia, the liver transits from an immune-tolerant towards an immune-active state and forms the first line of defense against invading microorganisms. the role of liver parenchymal cells in endotoxemia remains unintelligible. To characterize the liver parenchymal cells in endotoxemia liver, we performed single-cell RNA sequencing of liver parenchymal cells from healthy C57BL/6J mice and murine model of endotoxemia at early or late stage. The single-cell RNA-seq analyses revealed the heterogeneity of liver parenchymal cells in endotoxemia liver.
Project description:Liver has a crucial role in the regulation of immune defense in systemic infections. During endotoxemia, the liver transits from an immune-tolerant towards an immune-active state and forms the first line of defense against invading microorganisms. the role of liver nonparenchymal cells in endotoxemia remains unintelligible. To characterize the liver nonparenchymal cells in endotoxemia liver, we performed single-cell RNA sequencing of liver nonparenchymal cells from healthy C57BL/6J mice and murine model of endotoxemia at early or late stage. The single-cell RNA-seq analyses revealed the heterogeneity of liver nonparenchymal cells in endotoxemia liver.
Project description:To reveal the function of FABP7 in the inner ear, we evaluated gene expressions between Wild-type and Fabp7 KO mice one day after noise exposure at 10 weeks, using RNA sequencing analysis. The read number was approximately 27–32 million paired-end reads per sample. A total of 24 and 23 genes were identified as upregulated and downregulated differentially expressed genes (DEGs), respectively in Fabp7 KO mice. The upregulation of genes related to nicotinamide-adenine dinucleotide (NADH) dehydrogenase (mt-Nd1, 2, 3, 4, and 6) and a glial high-affinity glutamate transporter (solute carrier family 1, member 2: Slc1a2) and downregulation of genes related to C/D box small nucleolar RNAs were observed in Fabp7 KO mice.
