The RBP-Jκ Binding Sites within the RTA Promoter Regulate KSHV Latent Infection and Cell Proliferation

Quantitative analysis of KSHV BAC36 wt, RTA1st and BAC RTAall recombinant viruses infected PBMCs at 1dpi, 2dpi, 4dpi and 7dpi.
(A) Immunofluorescence assay for PBMCs infected by KSHV BAC36 wt, RTA1st and RTAall recombinant viruses at 2 dpi, 4 dpi and 7 dpi. Uninfected and infected PBMCs at 2 dpi, 4 dpi and 7 dpi were stained for LANA protein expression. PBMCs expressed GFP, indicating the presence of viral genome. (B, C). Quantitative analysis for determination of latent and lytic infection in PMBC cells infected by KSHV BAC36 wt, RTA1st and RTAall recombinant viruses. Total RNAs were extracted, treated with DNase I, and reverse transcribed to cDNA after 1 dpi, 2 dpi, 4 dpi and 7dpi. Quantitative Real-time PCR analysis with the primers for LANA and RTA was performed using StepOnePlus Real-Time PCR System. Error bars indicate standard deviations from three separate experiments.
