Next, the control and DCAF7-expressing A549 cells were infected with the H1N1 (MOI = 0.1) and H3N2 viruses (MOI = 0.2), expression of DCAF7 significantly reduced NP protein levels of both viruses and viral growth at the indicated infection time points (Fig. 2E; Fig. S1B). The gene discussed is DCAF7; the disease is infection.
