Immunohistochemistric analysis revealed that the percentages of EGFR+ or KI67+ cells and the levels of HIF-1α expression and microvessel density (MVD) in the XWLC-05-miR-370 tumor sections were significantly lower than that in the XWLC-05-miR-NC tumor sections (Figure 5H). Here, MKI67 is linked to neoplasm.
