doi: 10.1016/j.psj.2026.106566

Figure Lengend Snippet: Knockdown of eIF3m suppressed FAdV-4 replication in vitro. (A and B) LMH cells transfected with siRNA targeting at eIF3m or siNC as a negative control were collected at 24 h for qRT-PCR (A) and at 48 h for western blot (B) to evaluate the knockdown effect. (C and D) LMH cells transfected with 100nM/well siRNA or siNC were infected with CH/HNJZ/2015 at an MOI of 0.01. Western blot (C) and virus titration (D) were analyzed to investigate virus growth kinetics. The data shown represent the means±SD, and the experiments were repeated three times. The statistics analysis was performed by 2-way ANOVA. *, P < 0.05, **, P < 0.01.
