Project description:profiling gene transcription in a mouse model of permanent focal cerebral ischemia that was induced by middle cerebral artery occlusion (MCAO)
Project description:Focal ischemia is triggered by the sudden significant reduction of blood supply to the brain, as a result of either the rupture or occlusion by thrombus/embolism of a blood vessel in the brain. Permanent focal ischemia occurred when blood supply to a specific part of the brain is impeded without reperfusion. Despite major steps achieved in the elucidation of the patho-physiology of cerebral ischemia, the available therapeutic avenues for acute ischemic stroke remain scarce. Cell cycle re-activation has been revealed as a novel signaling pathway during permanent focal ischemia. As such, non-specific aurora kinase inhibitor ZM447439, has been injected intracranial-ventricularly30min post-ischemia induction to determine its efficacy in reduction of neuronal damage in terms of infarct volume. Microarray analysis was performed on Illumina Rat Ref12V1 beadchips. Right cortex RNA samples were collected at two time-points (8h and 24h ) respectively for all three experimental conditions: Sham (n=4), vehicle (i.e. ischemic injury with i.c.v. injection 80% DMSO; n=4) and treatment (injury plusi.c.v.injection of 30mM ZM447439 in 80% DMSO; n=4).
Project description:In order to establish a rat embryonic stem cell transcriptome, mRNA from rESC cell line DAc8, the first male germline competent rat ESC line to be described and the first to be used to generate a knockout rat model was characterized using RNA sequencing (RNA-seq) analysis.
