Deep sequencing analysis of the GeCKO cell populations showed more than 94% coverage for both libraries (≥ 10 reads for 61,598 and 54,609 sgRNA-coding sequences out of GeCKO populations were subjected to type 1 IFN treatment in order to induce the antiviral state and, 24h later, incubated with VSV-G-pseudotyped, HIV-1 based LVs coding for an antibiotic resistance cassette. In order to validate the effect of DDX42 KO on HIV-1 infection in another model cell line, two additional sgRNAs were designed (sgRNA-2 and -3) and used in parallel to the one identified in the GeCKO screen (sgDDX42-1) (Figure 2A ). ./cache/cord-271970-i35pic5o.txt ./txt/cord-271970-i35pic5o.txt
