Transcriptome analysis of heart regeneration in adult zebrafish

After heart injury, adult zebrafish can perfectly regenerate its heart without any scar tissue left. We performed 100bp*2, paired-end, strand-specific, polyA-positive RNA-seq on hearts from 2 group of adult zebrafish, in which one was sham group and the other 7 days after heart tip amputation (7dpa). We found pathways involving hydrogen peroxidate related functions significantly up-regulated in 7dpa group, indicating its role in heart regeneration. Overall design: RNA-seq: hearts from sham or 7dpa adult zebrafish
