JMJD6 expression is positively correlated with PD-L1 in GC tissues. Immunohistochemical staining of JMJD6 and PD-L1 was performed on GC tissues from 174 patients. Twenty high JMJD6-expressing cases and twenty low JMJD6-expressing cases were selected for PD-L1 staining and CPS evaluation. Representative images from four cases are shown. High JMJD6 expression was significantly associated with CPS ≥ 1 (P = 0.0281, Fisher’s exact test).
