Project description:This SuperSeries is composed of the following subset Series:; GSE9375: Striatal gene expression data from 12 months-old Hdh4/Q80 mice and control mice. GSE9857: Striatal gene expression data from 12 weeks-old R6/2 mice and control mice; GSE10202: Striatal gene expression data from 22-month-old CHL2 mice and control mice. Experiment Overall Design: Refer to individual Series
Project description:We identified the gene Far2, encoding the fatty acyl-coA reductase 2, to be associated with mesangial matrix expansion (MME) in the mouse (PMID: 24009241). In order to verify this association we obtained the C57BL/6N-Far2tm2a(KOMP)Wtsi/2J (JR#018805) strain from The Jackson Laboratory's KOMP2 program and compared this strain to it's control strain (C57BL/6N) for several renal characteristics. At 6 months of age the knockout mice have a significantly better kidney function (measured as glomerular filtration rate) but the MME is at a comparable level. However, as MME increases in the control strain at 12 months of age, MME does not increase in the knockout until 18 months of age. In order to explore changes at the gene expression level, we compared RNA sequence reads from 6-month old kidneys. Our analysis showed a decrease of RNA expression for several tubular damage markers (NGAL, KIM-1) and an increase in several genes in the fatty acid metabolism pathway.
Project description:The impact of Thbs1 gene deletion on BMEC activity during physiological aging is unknown. In this experiment, RNA Seq analysis was performed on BMECs derived from aged (18 month-old) Thbs1 knockout mice. BMECs derived from young (3 month-old) and aged (18 month-old) control mice were used as controls for comparison.
Project description:The impact of Thbs1 gene deletion on BM MSC activity during physiological aging is unknown. In this experiment, RNA Seq analysis was performed on BM MSCs derived from aged (18 month-old) Thbs1 knockout mice. MSCs derived from young (3 month-old) and aged (18 month-old) control mice were used as controls for comparison.
Project description:The impact of Thbs1 gene deletion on HSC activity during physiological aging is unknown. In this experiment, RNA Seq analysis was performed on BM HSCs derived from aged (18 month-old) Thbs1 knockout mice. HSCs derived from young (3 month-old) and aged (18 month-old) control mice were used as controls for comparison.
