Abstract

Methods of preparing a proteoliposome comprise the step of contacting a liposome with an effective portion of RalBP1 to create a proteoliposome. RalBP1 is effective for the protection and treatment of mammals and the environment against the accumulation of toxic compounds, and prevents accumulation of one or more toxic compounds, reduces the concentration of toxic compounds, and protects against further contamination with one or more toxic compounds. In addition, RalBP1 is effective for the protection and treatment of mammals against the effects of ionizing radiation.

Claims (30)

1. A method of treating the effects of exposure to ionizing radiation in a mammal in need of such treatment, comprising administering an effective amount of RLIP76 protein to the mammal within 24 hours of exposure to the ionizing radiation.

2. The method of claim 1 , wherein the mammal is human.

3. The method of claim 1 , wherein the ionizing radiation is x radiation, gamma radiation, ultraviolet radiation, thermal radiation, nuclear radiation, or a combination thereof.

4. The method of claim 1 , wherein the RLIP76 protein is administered within 24 hours before the exposure to the ionizing radiation.

5. The method of claim 1 , wherein the RLIP76 protein is administered within 24 hours after the exposure to the ionizing radiation.

6. The method of claim 1 wherein the RLIP76 protein is administered at about the time of the exposure to the ionizing radiation.

7. The method of claim 1 , wherein RLIP76 protein is comprised within a liposome.

8. The method of claim 1 , wherein the RLIP76 protein is administered in one or more doses to the mammal.

9. The method of claim 8 , wherein at least a first dose of the RLIP76 protein is administered within 24 hours before the exposure to the ionizing radiation.

10. The method of claim 8 , wherein at least a first dose of the RLIP76 protein is administered within 24 hours after the exposure to the ionizing radiation.

11. The method of claim 8 , wherein at least a first dose of the RLIP76 protein is administered at about the time of the exposure to the ionizing radiation.

12. The method of claim 9 , further comprising administering to the mammal at least a second dose of the RLIP76 protein within 24 hours after the exposure to the ionizing radiation.

13. The method of claim 12 , wherein the first dose and the second dose comprise about the same amount of the RLIP76 protein.

14. The method of claim 12 , wherein the first dose and the second dose comprise different amounts of the RLIP76 protein.

15. The method of claim 1 , wherein the RLIP76 protein is administered in one or more doses to the mammal within 24 hours before the exposure to the ionizing radiation.

16. The method of claim 15 , further comprising administering to the mammal one or more doses of the RLIP76 protein within 24 hours after the exposure to the ionizing radiation.

17. A method of treating the effects of exposure to ionizing radiation in a mammal in need of such treatment, comprising administering one or more doses of a proteoliposomal composition comprising an effective amount of RLIP76 protein or an effective portion thereof to the mammal within 24 hours of exposure to the ionizing radiation.

18. The method of claim 17 , wherein said proteoliposomal composition comprises between about 0.5 mg/kg body weight and about 14 mg/kg body weight of the RLIP76 protein.

19. The method of claim 17 , wherein the proteoliposomal composition further comprises a lectin, a glycolipid, a phospholipid, or a combination thereof.

20. The method of claim 17 , wherein the RLIP76 protein is a recombinant protein.

21. The method of claim 17 , wherein the one or more doses of proteoliposomal composition is administered subcutaneously, intravenously, topically, orally, non-orally, or a combination thereof.

22. The method of claim 21 , wherein the one or more doses of proteoliposomal composition is administered orally.

23. A method of treating the effects of exposure to ionizing radiation in a mammal in need of such treatment, comprising administering (a) at least a first dose of proteoliposomal composition comprising an effective amount of RLIP76 protein to the mammal before exposure to the ionizing radiation, and (b) at least a second dose of proteoliposomal composition comprising an effective amount of RLIP76 protein to the mammal after exposure to the ionizing radiation.

24. The method of claim 23 , wherein the mammal is human.

25. The method of claim 23 , wherein the ionizing radiation is x radiation, gamma radiation, ultraviolet radiation, thermal radiation, or nuclear radiation, or a combination thereof.

26. The method of claim 23 , wherein the first dose is administered within 24 hours before the exposure to the ionizing radiation.

27. The method of claim 23 , wherein the second dose is administered within 24 hours after the exposure to the ionizing radiation.

28. The method of claim 27 , further comprising administering to the mammal at least a third dose of proteoliposomal composition comprising an effective amount of RLIP76 protein to the mammal more than 24 hours after the exposure to the ionizing radiation.

29. The method of claim 23 , wherein the first dose and the second dose comprise about the same amount of the RLIP76 protein.

30. The method of claim 23 , wherein the first dose and the second dose comprise different amounts of the RLIP76 protein.
