Abstract:

Long noncording RNA (lncRNA) played an important regulating role in many biological processes.The lncRNA expression profile of liver of pre-laying hens (20 weeks old) and peak-laying hens (30 weeks old) in Lushi Green-shelled-egg chicken were obtained by lncRNA-seq. A lncRNA, which was named lncLER and expressed highly in the peak-laying hens was singled out. To investigate the expression characteristics of lncLER in liver of chicken,reverse-transcript PCR and Real-time fluorescence quantitative PCR were used to analyze the temporal expression profile of lncLER. Both individual chicken and primary hepatocytes were used to look into the effects of estradiol on expression of the lncLER in vivo and in vitro. The results showed that lncLER was expressed differently in various tissues and it's expression level was higher in the liver of peak-laying hens. The expression of lncLER, both in individual chicken and in primary hepatocytes,was up-regulated by estradiol.This research paved the way for further studying on the biological functions of lncLER in chicken egg production.

Key words: lncRNA; Lushi Green-shelled-egg chicken; estrogen; liver; expression and regulation
