miRNA profile of duck duodenum mucosa damage caused by oxidative stress
We deep sequenced and analyzed  miRNAs using deep RNA sequencing (RNA-seq) in cage rearing and traditional breeding duck's duodenum sample of Nonghu NO.2 duck.  21 differentially expressed miRNA were identified in the duodenum. 6 miRNAs were upregulated and 15 were downregulated in the cage rearing duck's duodenum of the Nonghu NO.2 duck compared to their expression in the control group. These findings provided insights into the expression profiles of miRNAs in duck duodenum, and deepened our understanding of miRNAs in oxidative injury of duck. Overall design: Examination of miRNA expression profile in cage rearing duck's duodenum and traditional breeding duck's duodenum samples
