Fig 4. EBV infection of ARID1A-knockout gastric cancer cells.

Fig 4

(A) The ARID1A gene was knocked out in the gastric cancer cell line MKN74 using CRISPR Cas9. Two ARID1A-knockout clones show a fibroblastic morphology of various degrees. (B) RT-PCR of BZLF1 gene of EBV, showing absence of expression in both EBV-infected parental MKN74 cells and ARID1A-knockout clones. (C) Parental MKN74 cells and ARID1A-knockout MKN74 clones #1 and #2 were infected with GFP-integrated cell-free EBV. Several ARID1A-knockout cells showed green fluorescence on Day 2. (D) Flow cytometry analyses of fluorescent-positive cells on Day 2. SSC, side scatter; FITC, fluorescein isothiocyanate.
