Figure 3From: Activation of AKT by hypoxia: a potential target for hypoxic tumors of the head and neck Expression of EGFR, pAKT and hypoxia in vivo . Expression of EGFR and pAKT in relation to hypoxia was analyzed by immunohistochemical analysis in UT-SCC xenograft tumors of 4 different lines. Left column: EGFR (red), pAKT (green), vessels (blue). Right column: EGFR (red), hypoxia (green), vessels (blue). Non-specific staining present in necrotic regions. Scale bars represent 500 ÎĽm. Magnification: 100X.Back to article page
