Fig. 5From: Intermittent hypoxia promotes melanoma lung metastasis via oxidative stress and inflammation responses in a mouse model of obstructive sleep apneaEffect of OSA-like IH on HIF-1α expression in a melanoma lung metastasis mouse model. a Western blotting analysis of HIF-1α expression in tumor tissue from mouse lungs after OSA-like IH exposure and/or tempol treatment (n = 3 per group). b The expression level of HIF-1α was evaluated by densitometric analysis of western blot bands. All data are expressed as the mean ± SEM. *P < 0.05Back to article page
