PG - 101-110 LID - S0378-1119(18)31027-8 [pii] LID - 10.1016/j.gene.2018.10.001 [doi] AB - An increasing number of evidences indicated that long noncoding RNAs (LncRNAs) regulate a variety of biological progresses via different mechanisms. Our previous study had identified a chicken growth hormone receptor (GHR) antisense transcript (GHR-AS) which regulated GHR sense transcript (GHR-S) in LMH cells. In the present study, roles of GHR-AS and its regulatory mechanism were analyzed in chicken hepatocytes. The expression patterns of liver GHR-S, GHR-AS and Let-7b ascended with the development of chicken. The hepatocytes proliferation was promoted and more cells entered into DNA synthesis (S) phase when GHR-AS was overexpressed while the cell proliferation was slowed and fewer cells were in S phase when GHR-AS was interfered. Meanwhile, the GHR-S increased when we overexpressed GHR-AS while it reduced when GHR-AS was inhibited. The S1 Nuclease protection assay indicated that GHR-S and GHR-AS formed RNA duplex via GHR-S 3' untranslation regon (3'UTR). In hepatocytes or LMH cells, the half-time of GHR-S showed a delayed trend when GHR-AS or GHR-AS 5' untranslation regon (5'UTR) was overexpressed. Furthermore, the level of GHR-S can be decreased by Let-7b mimics whereas it was partially rescued when co-transfected pGHR-AS or pGHR-AS 5'UTR with Let-7b mimics. Based on our findings, GHR-AS affected hepatocytes proliferation and improved GHR-S stability possibly by forming RNA duplex between GHR-S and GHR-AS, competing with Let-7b.
