Transcriptomics of small RNAs upon HHV-6A reactivation

In order to understand the effect of HHV-6A reactivation on host cell, U2-OS bone osteosarcoma cells were generated carrying latent HHV-6A genome. These cells were either treated with DMSO (solvent control) or Trichostatin-A (TSA) for viral reactivation. As a control cells carrying no HHV-6A were used and treated similarly. Two biological replicates of each sample were processed for small RNA transcriptomics (small RNAseq). Furthermore, HeLa (cervical epithelial cells) were generated carrying lentiviral insertions of one of the small non-coding RNA from HHV-6A (sncRNA-U14). These cells could be transiently induced for sncRNA-U14 transcription using Doxycycline. HeLa cells having a mock lentiviral backbone was used as a control and was treated similarly. Two biological replicates of each sample were processed for small RNA transcriptomics (small RNAseq). Small RNAseq was performed in 48 hr treated cells. Biological replicates were generated on a completely separate day using a different batch of cells.
