Description
Porcine satellite cells play a vital role in the construction, development, and self-renewal of skeletal muscle. In this study, porcine satellite cells were exposed to mimic viral infection poly (I:C) during proliferation and differentiation phases at 0h, 12h, 24h and 48h time points. The untreated and treated porcine satellite cells during proliferation and differentiation phases were further analyzed by RNA sequencing technology. In the proliferation and differentiation phases of porcine satellite cells grown under poly (I:C), 88, 119, 104 and 95 genes were differentially expressed in 0h – 12h treated, 12h – 24h treated, 0h – 24h treated and 24h – 48h untreated comparison libraries, respectively. The GO terms analysis results showed that in the proliferation phase of treated porcine satellite cells, the up-regulated genes related to the immune system were highly expressed. In addition, the gene expression associated with muscle structure development, response to growth factor emerged in the differentiation phase of untreated porcine satellite cells. The biological pathways associated with Influenza A, Toll-like signaling as well as chemokine signaling were revealed through poly (I:C) stimulation of porcine satellite cells. The differentially expressed genes were confirmed by quantitative real-time PCR. Our findings expanded the understanding of gene expression and signaling pathways about the infiltrated mechanism of the virus into porcine skeletal muscle satellite cells. Overall design: total RNA profiles of untreated and treated poly (I:C) conditions were generated by sequencing, in triplicate, using Illumina Hiseq 4000 platform.
