JPYZXZ diminished the expression of PD-L1 in GC cells. (A) The drug dosage curve of JPYZXZ on gastric cells after 24 h of exposure. (B,C) Representative images of PD-L1 immunofluorescence in MKN-74 cells. Scale bar = 20 μm. (D–I) Western blot analysis of PD-L1 and proteins in the IL-6/JAK2/STAT3 signaling pathway after JPYZXZ treatment. Data are expressed as mean ± SEM, n = 3 independent experiments. *p < 0.05, **p < 0.01.
