p53 directly regulates the transcription of the human frataxin gene and its lack of regulation in tumor cells decreases the utilization of mitochondrial iron

Mitochondrial frataxin functions in iron homeostasis, biogenesis of iron-sulfur clusters, protection from oxidative stress and apoptosis, and as a tumor suppressor protein. We examined regulation of the expression of the human frataxin by p53. Pifithrin-α, an inhibitor of p53 function, and knockdown of p53 decreased the level of frataxin mRNA in human kidney HEK 293T cells.
