Transcriptome analysis of mRNAs, lncRNAs, and circRNAs during the differentiation of porcine subcutaneous preadipocytes
Subcutaneous preadipocyte differentiation play a critical role in fat deposition of pigs. However, the action of different RNAs in subcutaneous preadipocyte differentiation, such as messenger RNAs (mRNAs), long noncoding RNAs (lncRNAs), and circular RNAs (circRNAs), are still largely unclear. In the present study, a transcriptome analysis including mRNAs, lncRNAs, and circRNAs was performed in different stages of D0, D2, D4, and D8 using RNA-seq technology. Our results identified 1,554, 470, 1,344, 1,777, and 676 differentially expressed (DE) mRNAs, 112, 58, 95, 136, and 93 DE lncRNAs, and 902, 787, 710, 932, and 850 DE circRNAs between D2 and D0, between D4 and D2, between D8 and D4, between D4 and D0, and between D8 and D0, respectively. Moreover, functional enrichment analysis showed that the common DE mRNAs during entire differentiation were mainly involved in lipid metabolic and cell differentiation processes. Additionally, co-expression network analysis identified the potential lncRNAs related to adipogenesis, e.g., MSTRG.42239 and MSTRG.146410. Taken together, this study provides a genome-wide landscape of RNA expression profiles during subcutaneous preadipocyte differentiation, thus improving our understanding of molecular mechanism in regulating subcutaneous adipogenesis of pigs. Overall design: mRNA, lncRNA, and circRNA profiles during the differentiation of porcine subcutaneous preadipocytes were generated by RNA-Seq using Illumina HiSeq X Ten.
