Popis: Long non-coding RNAs (lncRNAs) are important in feather development and feathering patterns, but few studies on this subject have been conducted in chickens. To understand the follicle development and feathering phenotypes, lncRNA expression profiles in chicken wing skin were determined and combined with previously determined miRNA and mRNA expression profiles of chicken wing skin. We then predicted some regulatory networks among differentially expressed mRNAs, miRNAs and lncRNAs using bioinformatics. Compared to chickens with no feathers growing out (N1 group), 778 lncRNAs were differentially expressed in early-feathering chicks with primary feathers more than 2 mm longer than primary-covert feathers (F1 group), and 443 lncRNAs were differentially expressed in late-feathering chicks with primary feathers shorter than primary-covert feathers (L2 group). Only 45 lncRNAs were differentially expressed between F1 and L2 (fold-change > 2, q
