Project description:In this study, we determined the effect of chronic consistent hypoxia (CCH) and chronic intermittent hypoxia (CIH) on global gene expression in cortical and hippocampal region of developing mouse brain using long-oligo beadschip arrays. Keywords: Gene expression profile Control-Cortex: Cortical samples from 16 days old mice were analysed on whole-genome expression chips to reveal expression profile at this developmental stage. Used as control for Chronic Hypoxia Treated cortical samples. CCH-Cortex: Cortical samples from 2-week CCH treated mice were analysed on whole-genome expression chips to reveal the changes in gene expression profile following 2-week CCH treatment. CIH-Cortex: Cortical samples from 2-week CCH treated mice were analysed on whole-genome expression chips to reveal the changes in gene expression profile following 2-week CIH treatment. Control-Hippocampus: Hippocampal samples from 16 days old mice were analysed on whole-genome expression chips to reveal expression profile at this developmental stage. Used as control for Chronic Hypoxia Treated hippocampal samples. CCH-Hippocampus: Hippocampal samples from 2-week CCH treated mice were analysed on whole-genome expression chips to reveal the changes in gene expression following 2-week CCH treatment. CIH-Hippocampus: Hippocampal samples from 2-week CCH treated mice were analysed on whole-genome expression chips to reveal the changes in gene expression following 2-week CIH treatment.

Project description:Since normal brain function depends upon continuous oxygen delivery and short periods of hypoxia can precondition against subsequent ischemia, this study examined the effects of brief hypoxia on the whole genome transcriptional response in adult mouse brain. Genomic expression profiling was perfromed for individual brain regions of the adult mice following the entire time course of hypoxia preconditioning.
Project description:Since normal brain function depends upon continuous oxygen delivery and short periods of hypoxia can precondition against subsequent ischemia, this study examined the effects of brief hypoxia on the whole genome transcriptional response in adult mouse brain. Genomic expression profiling was perfromed for individual brain regions of the adult mice following the entire time course of hypoxia preconditioning. Adult C57BL/6 male mice were exposed to systemic preconditioning hypoxia (8% O2 ) for 3 hr and allowed to recover in normoxia for 24 hr. The mouse brains were removed and dissected into individual brain regions at multiple time points during the 3hr hypoxia and subsequent 24hr reoxygenation periods. Total RNA was purified from the human whole blood or individual mouse brain regions. Genomic scale gene expression was then measured with Affymetrix Mouse Expression 430 2.0 arrays.
