In vitro effects on cell growth, mRNA expression levels of PD-1 and PD-L1 of Aza, LBH-589, MCT-3 or a combination of Aza and LBH589 in KG-1 cells. (A) In vitro effects on cell growth in KG-1 cells untreated (Con) or treated for 24 h with Aza, LBH-589 (LBH), MCT-3 or Aza+LBH as assessed by trypan blue staining. n=3. In vitro mRNA expression of (B) PD-1 and (C) PD-L1 mRNA in KG-1 cells untreated (Con) and treated for 24-h treatment with Aza, MCT-3, LBH or a combination of Aza+LBH. *P<0.05 vs. con, **P<0.01 vs. con, n=3-4. PD-1, programmed cell death protein 1; PD-L1, programmed death-ligand 1; Aza, azacytidine; Con, control.
