OCIAD1 and infection: Huh-7.5 cells were transfected with OCIAD1-targeting siRNAs #1 or #2 or a non-targeting control, followed by transduction with recombinant retroviruses allowing the expression of siRNA-resistant versions of OCIAD1, the uncleavable mutant OCIAD1C38A, the N-terminally truncated construct OCIAD1N39 or the green fluorescent protein (GFP) as a control, and, finally, infection with HCVcc.
