Context: Nicotinamide nucleotide transhydrogenase (NNT) is a NADPH-generating mitochondrial proton pump with a central role in mitochondrial antioxidant pathways. Recent studies revealed inactivating NNT mutations in patients with familial glucocorticoid deficiency, indicating a selective susceptibility of the adrenal cortex to NNT deficiency and oxidative stress. Here we explored the potential value of NNT as a therapeutic target in adrenocortical cancer.<p class="abstext...

Adrenocortical Carcinoma (ACC) is an aggressive malignancy with poor response to chemotherapy. Here we evaluated a potential new treatment target for ACC, focusing on the mitochondrial NADPH generator Nicotinamide Nucleotide Transhydrogenase (NNT). NNT has a central role within the mitochondrial antioxidant pathways, protecting cells from oxidative stress. Inactivating NNT mutations lead to isolated primary adrenal insufficiency, suggesting a selective vulnerability of adrenoc...
