B: HIF-2α levels in HT29 primary tumors. Left: Example of immunostaining in vehicle-treated controls. Inset, high-magnification image of the region marked with a green asterisk (*). Right: Quantification of the effect of monotherapies or doublet LDM/MTD regimens on HIF-2α+ area. F(5,18) = 1.215 and P = 0.3424 (not significant) for overall treatment by Brown-Forsythe ANOVA.
