HHV-6 alters host miRNA expression and mitochondrial dynamics. a Transcription dynamics of several human miRNAs were studied by Northern hybridization. U2OS cells having latent HHV-6A were used as described in figure 1f. Decade marker (M) was used to verify sizes of identified RNA. Both matured miRNA and their precursor (pre-miRNA) are indicated. Human U6 RNA was used as loading control. All gels derive from the same experiment and they were processed in parallel. b HHV-6A transactivation induces mitochondrial fragmentation. U2OS cells having soluble GFP (mito GFP) within mitochondria and carrying mCherry encoding latent HHV-6A was reactivated with TSA. DMSO treated cells served as solvent control. 2 days after treatment, cells were fixed and processed for confocal microscopy. The scale bars represent 10 μm. c Mitochondrial size and numbers were quantified using ImageJ. Data represent the mean ± SEM of three independent experiments.
