Regional brain expression maps for microRNAs in rats


ABSTRACT: MicroRNA transcriptional profiling of male Sprague-Dawley rats rat brains comparing microRNA abundance in five different brain regions. Two-condition experiment, regional brain samples vs. universal brain reference. Biological replicates: 4 samples from each region. One sample per array. Each array is divided into 3 replicate subarrays.

<h4>Background</h4>The brain is a major site of microRNA (miRNA) gene expression, but the spatial expression patterns of miRNAs within the brain have not yet been fully covered.<h4>Methodology/principal findings</h4>We have characterized the regional expression profiles of miRNAs in five distinct regions of the adult rat brain: amygdala, cerebellum, hippocampus, hypothalamus and substantia nigra. Microarray profiling uncovered 48 miRNAs displaying more than three-fold enrichment between two or m  ...[more]
