miR-18a increases the EBV viral load. a Transfection of miR-18a mimics in P3HR-1 and Raji resulted in a higher EBV viral load. Quantitative real-time EBV PCR was performed in samples collected from the culture media of cells. Viral DNA was extracted, and PCR was carried out according to the instructions. The EBV copy number was calculated according to a standard curve. b Expression of EBNA1 after transfection of miR-18a mimics and inhibitor in Raji cells as measured by western blotting. c Relative expression of EBV gene expression after transfection of miR-18a. d Visualization of episomal and integrated EBV DNA by fluorescence in situ hybridization
