The effect of African Swine Fever Virus infection on porcine host microRNAs
Large DNA viruses are known to manipulate and modify host miRNAs during infection. Therefore the aim of this study was to investigate the impact of infection with the large DNA virus; African swine fever virus (ASFV) on host miRNAs. Small RNA sequencing libraries were prepared from RNA extracted from ASFV (Benin 97/1) infected primary porcine macrophages at 0, 6 and 16 hours post infection. Libraries were pooled and sequenced on 1 lane of an Illumina HiSeq, yielding sequences aligning to a total of 247 different mature Sus scrofa miRNAs. On average, 3779095 (± 1911525) miRNA reads were obtained per sample. The results revealed no widespread modification to host miRNAs, though a number of specific miRNAs were differentially expressed during ASFV infection. Notably, a small number of miRNAs (Ssc-miR-10b, Ssc-miR-144 and Ssc-miR-486) were rapidly upregulated 2-6 fold within the first hour of infection.
