Figure Lengend Snippet: A. & B. Analysis of the impact of PALA co-treatment on ISG transcripts induced by IFNβ by qRT-PCR. Mx1, Isg15, and Ifit1 ( A. ) or Ifit2 and Oas1 ( B. ) transcript levels in Raw264.7 cells treated with IFNβ (200u/mL), PALA (100uM), or co-stimulation with IFNβ and PALA for 24h (n=4 experiments). Data presented as mean±SEM; significance determined by one-way ANOVA and Tukey’s multiple comparisons test; ns=not significant, *** p≤0.001 vs. NT, ++ p≤0.01 vs. IFN. C. PALA suppresses HCMV replication. ARPE-19 cells were infected with HCMV (MOI=3 TCID 50 /cell) and then cultured in media ±PALA (100μM). De novo cell-associated virus production was titered by TCID 50 assay on naïve NuFF-1 cells (n=3 experiments performed in triplicate; representative experiment shown). Data presented as mean±SEM; significance determined by one-way ANOVA and Sidak’s multiple comparisons test; ns=not significant, *p≤0.05, **p≤0.01 media vs. PALA; #p≤0.05, ##p≤0.01 vs. 24h sample. D. ARPE-19 cells were infected (MOI=3 TCID 50 /cell) and lysates collected at the indicated times post-infection. Expression of viral proteins were assessed by immunoblot probed with anti-IE1, anti-pUL44, and anti-tubulin (n=3 experiments; representative experiment shown).
Article Snippet: NuFF-1 cells (GlobalStem) were maintained in DMEM with 10% FBS, 2 mM L-glutamine, 0.1 mM non-essential amino acids, 10 mM HEPES, and 100 U/ml penicillin/streptomycin.
