Effect of DAC treatment on PD-L1 expression in the 1872 Col. DAC increased PD-L1 expression in the 1872 Col as shown by Western blot (tenfold increase; *p = 0.0128) (A) and Flow cytometry (11.3% in untreated cells vs. 69.1% after DAC treatment) (B). The data are from duplicate experiments and presented as mean ± SD (Paired t-test)
