摘要： Egg-ceasing is a phenomenon that occurs in most avian species and significantly reduces productivity. Although several factors are reported to regulate the reproduction progress, the underlying molecular mechanism of egg-ceasing remains obscure. Herein, we identified and explored the differentially expressed miRNAs and mRNAs involved in ovarian atrophy via high throughput sequencing. We identified a total of 901 mRNAs and 50 miRNAs that were differentially expressed in egg-laying and atrophic ovaries. Among them, numerous differentially expressed gene (DEG) transcripts and target genes for miRNAs were significantly enriched in Gene Ontology terms such as reproductive processes, cell proliferation, and apoptosis pathways. In addition, an interaction network was constructed by considering target relationships and correlation of the expression levels between ovary development-related genes, miRNAs and pathways. We discovered mRNA and miRNAs transcripts that are candidate regulators of ovary development in egg-ceased geese. Our findings expanded our understanding of the functional of miRNAs in ovarian atrophy and demonstrated that RNA-Seq is a powerful tool for examining the molecular mechanism in regulating egg-ceasing.(c) 2022 Elsevier Inc.
