Abstract:

The aim was to screen key differentially expressed genes and signaling pathways and explore the molecular regulatory mechanisms of chicken skin follicle traits through transcriptomic analysis of the dorsal skin follicle tissues of Chongren partridge chicken.Total RNA of skin hair follicle tissue was extracted by TRIzol method,and transcriptome high-throughput sequencing(RNA-Seq)was performed by Illumina platform.Finally,the transcriptome sequencing was validated by Real-time fluorescence quantitative PCR.The results were as follows:A total of 3 856 differentially expressed genes were screened,and 971 differentially expressed genes were screened in the cockerel(BGB vs YGB)comparative combinations,of these,274 up-regulated and 697 down-regulated.There were 3 529 differentially expressed genes in comparative combinations of hen(BMB vs YMB),of these,1 477 up-regulated and 2 052 down-regulated.Three highly expressed genes,KRT75,KRT6A,and KRT14,associated with skin follicle traits,were screened among the common differentially expressed genes in roosters and hens.In the significant enrichment of GO functions,516 GO terms were enriched in the BGB vs YGB and 1 020 GO terms were enriched in the BMB vs YMB.Genes were mainly focused on activities involved in cell adhesion and cell activation.Significantly enriched multiple KEGG pathways,with 8 significant KEGG pathways enriched in the BGB vs YGB and 20 significant KEGG pathways enriched in the BMB vs YMB.Three key pathways,Wnt signaling pathway,neuroactive ligand-receptor regulatory pathway and TGF-β regulatory pathway,were screened.Fluorescence quantification showed that the expression of five randomly selected differential genes in skin hair follicles was consistent with the trend towards RNA-Seq.In summary,the screened KRT75,KRT6A,and KRT14 genes may affect chicken skin follicle traits;the neuroactive ligand-receptor regulatory pathway,the Wnt signaling pathway,and the TGF-β signaling pathway are important pathways that regulate follicular traits in chicken skin.
