MiR-93-5p regulates tumor immunology by targeting PD-L1. In tissues with low expression of miR-93-5p (BCIP/NBT staining), PD-L1 and CD8 were highly expressed (DAB staining), and in tissues with high expression of miR-93-5p, PD-L1 and CD8 was low. These expression trends were consistent in breast cancer (magnification was 200 µm and 400 µm). PD-L1, programmed cell death-ligand 1.
