Fig. 6. STAT3 overexpression reverses the inhibition of miR-526b-3p in cancer metastasis.
a The representative images of lung metastasis by hematoxylin and eosin stains are shown. Scale bar, 20 µm. b The representative images of PD-L1 expression by immunohistochemical stain are shown. Scale bar, 50 µm. c The expression of the indicated genes is determined by western blot and qRT-PCR, respectively. *, P < 0.05 vs. control. #, P < 0.05 vs miR-526b-3p plus vector.
