NDRG2 overexpression reduces the expression of PD-L1, p-STAT3, and p-p65. (A) PD-L1 expression in 4T1-wild-type, -mock (M), and -NDRG2 (N2) cells was measured by flow cytometry. (B) The expression levels of NDRG2, p-STAT3, and p-p65 (p-NF-κB) in 4T1-mock and 4T1-NDRG2 cells were examined by Western blot analysis. All experiments were independently repeated at least 3 times. * p < 0.05, *** p < 0.001, and **** p < 0.0001. The uncropped blots and molecular weight markers are shown in Supplementary Materials.
