Decreasing expression level of apoptosis-related genes by treating a human subject with a nitroxide

1. A method for decreasing the expression level of a gene in a human subject in need thereof, comprising:

identifying a human subject having an increased expression level of a gene associated with a disease, wherein the gene associated with the disease is selected from the group consisting of Bak1, Pdcd5, Casp2, Tradd, Tp53inp1 and Casp12; and

administering to the human subject an effective amount of a nitroxide antioxidant to reduce the level of expression of the gene associated with the disease, wherein the nitroxide antioxidant is 4-hydroxy-2,2,6,6-tetramethylpiperidine-1-oxyl.

2. The method of claim 1 , whereby the expression level of the gene associated with the disease is reduced in the human subject.

3. The method of claim 1 , whereby the expression level of the gene associated with the disease is reduced in a tissue of the human subject selected from the group consisting of a skin tissue, an immune tissue, a pancreatic tissue, and a neuronal tissue.

4. The method of claim 1 , wherein the human subject is over the age of 35 or over the age of 55.

5. The method of claim 1 , wherein the gene associated with the disease is Pdcd5 or Casp2.

6. The method of claim 1 , wherein the gene associated with the disease is Casp2 or Tradd.

7. The method of claim 1 , wherein the gene associated with the disease is Tradd or Pdcd5.

8. A method for decreasing the expression level of a gene in a human subject in need thereof, comprising:

administering to a human subject, at risk of a disease associated with an increased expression of a gene, an effective amount of a nitroxide antioxidant to reduce the level of expression of the gene associated with the disease, wherein the gene is selected from Pdcd5, Casp2, and Tradd, wherein the nitroxide antioxidant is 4-hydroxy- 2,2,6,6-tetramethylpiperidine-1-oxyl.

9. The method of claim 8 , whereby the expression level of the gene associated with the disease is reduced in the human subject.

10. The method of claim 8 , whereby the expression level of the gene associated with the disease is reduced in a tissue of the human subject selected from the group consisting of a skin tissue, an immune tissue, a pancreatic tissue, and a neuronal tissue.

11. The method of claim 8 , wherein the human subject is over the age of 35.

12. The method of claim 8 , wherein the human subject is over the age of 55.

13. The method of claim 8 , wherein the gene associated with the disease is Pdcd5.

14. The method of claim 8 , wherein the gene associated with the disease is Casp2.

15. The method of claim 8 , wherein the gene associated with the disease is Tradd.

16. A method for decreasing the expression level of a gene in a human subject in need thereof, comprising:

administering to a human subject, known to have an increased expression of a gene associated with a disease, an effective amount of a nitroxide antioxidant to reduce the level of expression of the gene associated with the disease, wherein the gene associated with the disease is selected from Bak1, Tp53inp1, and Casp12, wherein the nitroxide antioxidant is 4-hydroxy-2,2,6,6-tetramethylpiperidine-1-oxyl.

17. The method of claim 16 , whereby the expression level of the gene associated with the disease is reduced in the human subject.

18. The method of claim 16 , whereby the expression level of the gene associated with the disease is reduced in a tissue of the human subject selected from the group consisting of a skin tissue, an immune tissue, a pancreatic tissue, and a neuronal tissue.

19. The method of claim 16 , wherein the human subject is over the age of 35 or over the age of 55.

20. The method of claim 16 , wherein the gene associated with the disease is Bak1 or Tp53inp1.

21. The method of claim 16 , wherein the gene associated with the disease is Tp53inp1 or Casp12.

22. The method of claim 16 , wherein the gene associated with the disease is Bak1 or Casp12.

23. A method for decreasing the expression level of a gene in a human subject in need thereof, comprising:

administering to a human subject, at risk of a disease associated with an increased expression of a gene, an effective amount of a nitroxide antioxidant to reduce the level of expression of the gene associated with the disease, wherein the gene is selected from Bak1, Tp53inp1, and Casp12, wherein the nitroxide antioxidant is 4-hydroxy-2,2,6,6-tetramethylpiperidine-1-oxyl.

24. The method of claim 23 , whereby the expression level of the gene associated with the disease is reduced in the human subject.

25. The method of claim 23 , whereby the expression level of the gene associated with the disease is reduced in a tissue of the human subject selected from the group consisting of a skin tissue, an immune tissue, a pancreatic tissue, and a neuronal tissue.

26. The method of claim 23 , wherein the human subject is over the age of 35.

27. The method of claim 23 , wherein the human subject is over the age of 55.

28. The method of claim 23 , wherein the gene associated with the disease is Bak1.

29. The method of claim 23 , wherein the gene associated with the disease is Tp53inp1.

30. The method of claim 23 , wherein the gene associated with the disease is Casp12.
