MicroRNAs benefit NDV replication. (A) Nucleocapsid protein (NP) mRNA was detected with RT-qPCR in HeLa cells transfected with miRNA mimics and then infected with NDV. β-Actin was an internal control. (B) NP protein was detected by Western blot in HeLa cells transfected with miRNA mimics and then infected with NDV. β-actin was an internal control. (C) The integrated density of NP expression was analyzed in (B) with Image J software 1.8.0. β-actin was an internal control. Error bars are the SEM from three independent experiments. Statistical significance is indicated: ** p < 0.01 and * p < 0.05.
