Abstract:

The hair follicles of Dorper sheep are characterised by cyclic growth and development,which is generally divided into three periods:anagen,catagen,and telogen.This study aims to explore the regulatory mechanism of key lncRNAs as ceRNA associated with hair follicles anagen and telogen as screened by previous studies.Ten Dorper ewes (shedding group,S group) with extreme shedding phenotypes and 10 non-shedding ewes (non-shedding group,N group) were selected under the same feeding conditions,with similar body weights and sizes,and about 2 years old,and the best 5 shedding ewes and 3 non-shedding ewes were selected for transcriptome sequencing after phenotypic observation.The ceRNA regulatory network of key lncRNAs was constructed by bioinformatics analysis methods such as target prediction,expression pattern analysis,and GO and KEGG enrichment analysis,to further investigate the regulatory mechanisms of key lncRNAs.The results showed a total of 262 mRNAs were screened by lncRNA-miRNA and miRNA-mRNA target prediction analysis,of which 135 mRNAs were consistent with the expression patterns of the corresponding lncRNAs (19 A pattern (Anagen,highly expressed in anagen) and 116 T pattern (Telogen,highly expressed in telogen)).GO and KEGG enrichment analysis of these 135 mRNAs revealed that some genes associated with development of hair follicles,such as CTNNB1,FGF22,FGF5,FZD3,JAK3,Lpar6,NGFR,PAK1,EIF4E,and Wnt10b,were enriched in Rap1,MAPK,Wnt,PI3K-Akt,Ras,mTOR,Jak-STAT,Hippo and other signaling pathways,which were associated with development of hair follicles.A ceRNA regulatory network consisting of 10 lncRNAs,11 miRNAs and 10 mRNAs was finally constructed.The qRT-PCR of several randomly selected differentially expressed lncRNAs and differentially expressed genes showed that the expression trend was basically consistent with that of the transcriptome sequencing results,indicating that the sequencing result was reliable.These 10 lncRNAs obtained from the study together with their target-regulated miRNAs and mRNAs can be the focus of research on the development of hair follicles in sheep.
