Increasing expression level of apoptosis-related genes by treating a human subject with a nitroxide
View Patent ↗Disclosed herein are methods for counteracting age-related decrease in gene expression or treating age-related diseases, for example cancers and autoimmune diseases, caused by decreased expression levels of a gene associated with the apoptosis pathway, using a nitroxide. Further disclosed are methods for treating a human subject in need of an increased expression level of a gene associated with the apoptosis pathway using a nitroxide.
1. A method of increasing expression level of Bcl-2-associated athanogene 5 (Bag5) gene in an individual, comprising:
identifying an individual having a downregulated expression level of the Bag5 gene in neuronal tissue relative to the expression level of Bag5 gene in neuronal tissue of a population of individuals of the same sex and similar age; and
administering to the individual an effective amount of a nitroxide antioxidant, the nitroxide antioxidant selected from the group consisting of 2-ethyl-2,5,5-trimethyl-3-oxazolidine-1-oxyl (OXANO), 2,2,6,6-tetramethylpiperidine-1 oxyl (TEMPO), 4-hydroxy-2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPOL), 4-amino-2,2,6,6-tetramethyl-1-piperidinyloxy (Tempatmine), 3-Aminomethyl-PROXYL, 3-Cyano-PROXYL, 3-Carbamoyl-PROXYL, 3-Carboxy-PROXYL, and 4-Oxo-TEMPO, and
whereby the expression level Bag5 is increased to prevent neuronal cell death in the neuronal tissue.
2. The method of claim 1 , wherein the nitroxide antioxidant is TEMPOL.
3. The method of claim 2 , wherein the individual has been diagnosed with Alzheimer's disease.
4. The method of claim 2 , wherein the individual has been diagnosed with Parkinson's disease.
5. The method of claim 2 , wherein the individual has been diagnosed with Huntington's disease.
6. The method of claim 2 , wherein the individual has been diagnosed with amyotrophic lateral sclerosis.
7. The method of claim 2 , wherein the individual has been diagnosed with spinal ataxis.
8. The method of claim 2 , wherein the individual has been diagnosed with spinocerebellar degenerations.
9. The method of claim 2 , wherein the individual has been diagnosed with an age-related neurodegenerative disease.
