Memory of Prior IFNγ Induction Is Reversible but Persists for up to 14 Days in Continuously Cycling Cells
(A) Scheme outlining the experiment to determine the duration of IFNγ-mediated transcriptional memory.
(B) Cells subjected to the IFNγ treatment regimen outlined in (A) were processed for western blotting and probed for GBP5 protein expression. α-TUB, loading control.
(C) Cells as in (B) but processed for RT-qPCR of GBP5 and HLA-DRA mRNA. Expression levels were normalized to ACTB and internally to cells after priming. Error bars, SD; n = 3 biological replicates; numbers represent the p values.
