Stroke target identification guided by astrocyte transcriptome analysis [pool]

We aimed to investigate the influence of ischemic stroke in mice on their ribosomal mRNA in astrocytes. Therefore, we make use of the conditional Cre/LoxP System in the RiboTag mouse line in order to isolate the ribosomal mRNA of astrocytes. CreERT2 expression under the astrocyte-specific Cx43 promoter is induced by Tamoxifen injection and activates the expression of a haemagglutinin tag on ribosomal proteins. 3 weeks after Tamoxifen induction, mice were subjected to a 60 min middle cerebral artery occlusion (tMCAO), which is an established ischemic stroke model. Control mice were not further treated. Overall design: Pool from 3 animals in each group, 2 technical replicates each. From each sample RNA was extracted by IP two times and pooled back together.
