GSE45152: Interrogating translating RNAs and cell-type specific gene expression using Cre-activated translating ribosome affinity purification

• Organsim mouse
• Type RNASEQ
• Target gene
• Project ARCHS4

We characterize a Cre-activated TRAP allele (Rosa26fsTRAP) to show that endothelium-specific activation of Rosa26fsTRAP identifies endothelial cell enriched transcripts, and that cardiomyocyte-restricted TRAP is a useful means to identify genes that are differentially expressed in cardiomyocytes in a disease model. We also show that TRAP is an effective means to study translational regulation, and we several nuclear-encoded mitochondrial genes are under strong translational control. These RNA-seq data show that the TRAP strategy and the Rosa26fsTRAP allele will be useful tools to probe cell type specific transcriptomes, and to study translational regulation.
