The porcine piRNA transcriptome response to Senecavirus A infection

Project description:Senecavirus A (SVA) belongs to the family of small RNA viruses, the genus Senecavirus, and has become a research hotspot because of the oncolytic viral characteristics. PIWI-interacting RNAs (piRNAs) are a class of small RNAs found in mammalian cells in recent years; however, the host piRNA expression profile during SVA infection and their role in viral infection is not well understood. In this study, we obtained small RNA transcriptome expression profiles from SVA-infected pig kidney cell lines (PK-15) by high-throughput sequencing. Differential expression (DE) analysis, GO annotation, and KEGG analysis of piRNAs in SVA-infected and non-infected PK-15 cells were performed. qRT-PCR was used to validate the DE of piRNAs. The results showed that 981 and 1,370 novel piRNAs were identified in SVA-infected and non-infected PK-15 cells; expression of 129 piRNAs was upregulated while that of 44 piRNAs was downregulated after SVA infection. The DE of 10 piRNAs was further verified by qRT-PCR. GO annotation analysis results showed the metabolism, proliferation, and differentiation were significantly activated after SVA infection. KEGG results showed that after SVA infection, piRNA was mainly enriched in AMPK signaling pathway, Rap1 signaling pathway, circadian rhythm, and VEGF signaling pathway, which suggested that piRNAs may play a role in regulating antiviral immunity, intracellular homeostasis, and tumor processes during SVA infection. This is the first report of the piRNA transcriptome in pig kidney cells and will contribute to the research of piRNA regulatory mechanism during SVA infections and provide an important reference for the prevention and treatment of SVA.

Identification of lncRNAs involved in the PCV2 infection of PK-15 cells

Project description:Porcine circovirus type 2 (PCV2) can cause severe disease in the affected pigs, resulting in massive economic loss for the swine industry. Transcriptomics and proteomics approaches have been widely employed to identify the underlying molecular mechanisms of PCV2 infection. Numerous differentially expressed mRNAs, miRNAs, and proteins, together with their associated signaling pathways, have been identified, paving the way to further validation of their biological functions. Long non-coding RNA (lncRNA) is an important regulator of multiple biological processes. However, rare information regarding its role in the PCV2 infection has been obtained. Hence, in our study, RNA-seq was performed by infecting PK-15 cells with PCV2. Analysis of the differentially expressed genes (DEGs) suggested that cytoskeleton, apoptosis, cell division, and protein phosphorylation were significantly disturbed. Then, using stringent parameters, six lncRNAs were identified. Additionally, the potential targets of the lncRNAs were predicted using both cis- and trans-prediction methods. Interestingly, we found that the HOXB (Homeobox B) gene cluster was probably the target of the lncRNA LOC106505099. Enrichment analysis of the target genes showed that numerous developmental processes were altered during PCV2 infection. Therefore, our study revealed that lncRNAs could affect porcine embryo development through the regulation of the HOXB genes.
