Mitochondrial bioenergetic profile and responses to metabolic inhibition in human hepatocarcinoma cell lines with distinct differentiation characteristics.

The classical view of tumour cell bioenergetics has been recently revised. Then, the definition of the mitochondrial profile is considered of fundamental importance for the development of anti-cancer therapies, but it still needs to be clarified. We investigated two human hepatocellular carcinoma cell lines: the partially differentiated HepG2 and the undifferentiated JHH-6.
