NQO1 and adrenoleukodystrophy: In this study we analyzed the expression of GPX4, GR, NQO1, and GSH, the focal node of the endogenous lipid-targeted antioxidant response, in fibroblasts of patients with AMN, the late onset and slowly progressive form of X-ALD, and in cALD, the cerebral inflammatory demyelinating form of early childhood, with the main objective to understand if they were differently modulated in the two clinical forms of the disease.
