Hypoxia-inducible factor-1α at the invasive tumor front in oral squamous cell carcinoma

Figure 2 Correlation of hypoxia-inducible factor 1-alpha expression with vimentin expression. A: Immunohistochemical expression of hypoxia-inducible factor 1-alpha (HIF-1α); B: Vimentin expression, which was significantly correlated with HIF-1α (P = 0.017). (Immunohistochemistry, 20 × magnification); C: HIF-1α expression (green); D: Vimentin expression (magenta); E: Colocalization of HIF-1α and vimentin (white) in images obtained via confocal microscopy (Immunofluorescence, 63 × magnification); F: Vimentin expression was significantly correlated with HIF-1α (P = 0.017).
