Next Generation Sequencing Analysis of gene expression profile in Dgcr8 conditional KO embryonic hearts. Mus musculus

Purpose: To compare the transcriptome of wild type and Mesp1Cre+/Dgcr8-/- embryonic heart at embryonic stage E8.5 and E9.5 Methods: For mRNA analysis of embryonic heart during development, total RNA of E8.5 and E9.5 heart were extracted with TRIZOL, and 100ng total RNA was reverse transcribed and amplified by Smart-seq 2 protocol as described (Picelli et al., 2014). Duplicated biological samples were analyzed using Illumina HiSeq2500, Clean reads were mapped to mouse genome (mm9) using BWA software. Results: Genes significantly differentially expressed in the CKO cardiac tube at E9.5 compared with wild type were identified. Conclusions: Dgcr8 CKO caused important gene expression changes in E9.5 embryonic heart tube Overall design: Perform RNA-seq of wild type and Mesp1Cre+/Dgcr8-/- embryonic heart at embryonic stage E8.5 and E9.5
