The changes in cellular microRNA (miRNA) expression during the course of an adenovirus type 2 infection in human lung fibroblast were studied by deep RNA sequencing. Expressions of 175 miRNAs with over 100 transcripts per million nucleotides were changed more than 1.5-fold. The expression patterns of these miRNAs changed dramatically during the course of the infection, from upregulation of the miRNAs known as tumor suppressors (such as miR-22, miR-320, let-7, miR-181b, and miR-155) and down-regulation of oncogenic miRNAs (such as miR-21 and miR-31) early to downregulation of tumor suppressor miRNAs (such as let-7 family, mir-30 family, 23/27 cluster) and upregulation of oncogenic miRNAs (include miR-125, miR-27, miR-191) late after infection. The switch in miRNA expression pattern occurred when adenovirus DNA replication started. Furthermore, deregulation of cellular miRNA expression was a step-wise and special sets of miRNAs were deregulated in different phases of infection.
