miR-4759 is inversely correlated with PD-L1 expression in human breast tumors. (A) Representative ISH images of miR-4759 and IHC images of PD-L1 in 181 breast cancer specimens. (B) IHC staining of PD-L1 was scored and the data were plotted. PD-L1 expressions were compared between low miR-4759 level and high miR-4759 level (separated by average value), Bars, mean (the middle bar), and the standard deviation (the upper and lower bars). Statistical significance was tested by an unpaired t-test. ***, p < 0.001.
