Cellular hsa-miR-200 inhibits wild-type infection but not infection with an UL122 (IE2) 3′ UTR mutant virus. (A) Primary human embryonic lung <t>fibroblasts</t> (MRC5 cells) were stably transduced with either a control retrovirus or one that overexpressed the C1 cluster of the hsa-miR-200 family. In each cell type, levels of hsa-miR-200b (light gray bars) or hsa-miR-200c (dark gray bars) were assessed by qPCR. Samples were normalized to those of cellular RNU44 and analyzed in triplicate. (B, C) MRC5 cells stably transduced with a C1-expressing lentivirus (white bars) or an empty control (gray bars) were then infected with either wild-type FixBACgfp virus (B) or FixBACgfpIE2cisΔ virus (C) at a multiplicity of 0.5 PFU/cell for 4 days. The titer of cell-free virus was then determined by a modified immunofluorescence assay for IE1. Samples were analyzed in triplicate. (D) MRC5 cells transduced with either the C1-expressing or control lentivirus were infected with either wild-type FixBACgfp virus or FixBACgfpIE2cisΔ virus at a multiplicity of 1 PFU/cell. Cell lysates were harvested at the indicated time points (hpi, hours postinfection), and IE2 levels were assessed using a monoclonal antibody (clone 3A9). α-Tubulin was used as a control.

Cellular hsa-miR-200 inhibits wild-type infection but not infection with an UL122 (IE2) 3′ UTR mutant virus. (A) Primary human embryonic lung fibroblasts (MRC5 cells) were stably transduced with either a control retrovirus or one that overexpressed the C1 cluster of the hsa-miR-200 family.
