Abstract
Providing Nuclear factor (erythroid-derived 2)-like 2 (NRF2)-activated genes products, e.g. SOD1 and CAT, in their use in the prognosis of an OPA1 gene- or OPA1 gene product-deficit-induced disease, or related complications, e.g. optic atrophy and optic neuropathy, in a biological sample selected from fibroblasts, epithelial cells, blood samples or a mixture thereof, of a patient affected or suspected to be affected by the disease.
Claims5
A method for the in vitro diagnosis and treatment of OPA1-deficit induced autosomal dominant optic atrophy (DOA, OMIM# 165500) and/or a complication associated with OPA1-deficit induced DOA selected from “DOA plus” syndrome disorders in a subject, comprising
- measuring in a biological sample selected from the group consisting of fibroblasts, epithelial cells, blood samples and mixtures thereof, of said subject, expression and/or activity of a Nuclear Factor (erythroid-derived 2)-like 2 (NRF2)-activated gene product selected from the group consisting of NRF2, SOD1, SOD2, catalase, GSTP1, NQO1, Glutathione Reductase, Peroxiredoxin 1, Hemeoxigenase 1, Thioredoxin reductase 1, and Glutamate Cystein Ligase,
- comparing said expression and/or activity measured in said biological sample of said subject to that of a measured expression and/or activity of a same NRF2-activated gene product in a biological sample selected from the group consisting of fibroblasts, epithelial cells, blood samples and a mixture thereof taken from a control subject,
- determining that said expression and/or activity measured in said biological sample from said subject is lower than said measured expression and/or activity in said biological sample from said control subject, and concluding said subject as suffering from said OPA1-deficit induced DOA and/or said complication associated with OPA1-deficit induced DOA,
- administering to said subject suffering from said OPA1-deficit induced DOA and/or said complication associated with OPA1-deficit induced DOA a treatment comprising administering at least one compound selected from the group consisting of Glutathione, Vitamin A, Vitamin C, Vitamin E, Coenzyme Q10 and Coenzyme Q10 analogs, Manganese, Iodide, Carotenoid terpenoids, Natural phenols, Phenolic acids and their esters, nonflavonoid phenolics, organic antioxidants selected from the group consisting of Capsaicin, Bilirubin, oxalic acid, phytic acid, N-Acetylcysteine, R-α-Lipoic acid, and fat and water soluble Uric acid, ARE inducers selected from the Sulforafane, Nordihydroguaiaretic acid, Diallyl Sulfid, Diallyl disulfid, Diallyl trisulfid, Pterostilbene, 1,2-dithiole-3-thione (D3T), 5,6-dihydro-cyclopento-(c)-1,2-dithiole-(4H)-thione (CPDT), Oltipraz, Salicylcurcuminoids, BG12, and Bardoxolonemethyl, and combinations thereof.
