Clofibrate enhances the interaction of HIF-1α and pVHL (densitometric analysis of the Western blot data presented in Fig. 4D)

Intensities were normalized to input levels of the same proteins and are expressed as levels relative to controls under normoxia (n = 3).

	Normoxia		Hypoxia
	Control	Clofibrate	Control	Clofibrate
pVHL	1.0	1.3 ± 0.3	0.9 ± 0.3	1.6 ± 0.4a
HIF-1α	1.0	0.8 ± 0.2	1.2 ± 0.3	0.9 ± 0.2

^a p < 0.05 compared with the control using one-way ANOVA.
