Moreover, since the BC cell lines studied here showed a different mitochondrial function, we analyzed the expression of adenine monophosphate-activated protein kinase (AMPK) and hypoxia-inducible factor 1α (HIF1α) (Figure 5A) [35], to evaluate the relative contribution of oxidative and glycolytic metabolism, respectively, in both BC cell lines. Here, HIF1A is linked to breast cancer.
