Abstract

Background: Muscle and adipose tissue are the most critical indicators of beef quality, and their development and function are regulated by noncoding RNAs (ncRNAs). However, the differential regulatory mechanisms of ncRNAs in muscle and adipose tissue remain unclear.

Results: In this study, 2,343 differentially expressed mRNAs (DEMs), 235 differentially expressed lncRNAs (DELs), 95 differentially expressed circRNAs (DECs) and 54 differentially expressed miRNAs (DEmiRs) were identified in longissimus dorsi muscle (LD), subcutaneous fat (SF) and perirenal fat (VF) in Qinchuan beef cattle. The results of functional enrichment analysis showed that DEMs, DELs, DECs and DEmiRs were enriched in biological processes related to development and function of muscle and fat deposition, including skeletal muscle contraction, muscle organ development, PPAR signaling pathway, fatty acid metabolism and MAPK signaling pathway. Based on the competing endogenous RNA (ceRNA) regulatory mechanism, we constructed a lncRNA/circRNA-miRNA-mRNA network consisting of 6 circRNAs, 5 lncRNAs, 6 miRNAs and 27 mRNAs. Among them, 55 ceRNA axes were involved, including circRNA12990 - bta-miR-133a_L-1R + 1 - MYO6/ZEB2, circRNA2893/MSTRG.28538.1/MSTRG.11613.4 - pma-miR-145-5p_R + 2 - EYA4 and MSTRG.26982.1 - bta-let-7e_R + 1 - RBM40.

Conclusions: This study identified a group of differentially expressed mRNAs, lncRNAs, circRNAs and miRNAs between muscle and adipose tissue and constructed a potential ceRNA regulatory network, which may serve as a foundation for studying the differential regulatory roles of ncRNAs in the development and function of muscle and adipose tissue.

期刊介绍： BMC Genomics is an open access, peer-reviewed journal that considers articles on all aspects of genome-scale analysis, functional genomics, and proteomics. BMC Genomics is part of the BMC series which publishes subject-specific journals focused on the needs of individual research communities across all areas of biology and medicine. We offer an efficient, fair and friendly peer review service, and are committed to publishing all sound science, provided that there is some advance in knowledge presented by the work.
