Abstract

A method of treating a glycosylation-defective protein associated disease or disorder in a subject, the method includes administering to the subject a therapeutically effective amount of a Sarco/ER ATPase (SERCA) inhibitor.

Claims (20)

1. A method of treating a glycosylation-defective protein associated disease or disorder in a subject in need thereof, the method comprising:

administering to the subject a therapeutically effective amount of a Sarco/ER ATPase (SERCA) inhibitor, wherein the SERCA inhibitor induces unconventional secretory pathway transport of aggregated glycosylation-defective protein from endoplasmic reticulum of cells of the subject.

2. The method of claim 1 , wherein the SERCA inhibitor reduces endoplasmic reticulum luminal calcium levels.

3. The method of claim 1 , wherein the SERCA inhibitor induces activation of the GRASP55 cargo dependent unconventional secretory pathway (GCUSP).

4. The method of claim 1 , the SERCA inhibitor selected from the group consisting of Artemisinin, Artesunate (Arts), thapsigargin, mipsagargin, DBHQ (2,5-di-tert-butylhydroquinone), Saikosaponin-d (Ssd), SBF-1, ruthenium red, curcumin, F36, gingerol, paxilline, cyclopiazonic acid, sHA14-1, CXL017, and analogs thereof.

5. The method of claim 1 , the SERCA inhibitor comprising Artesunate (Arts).

6. The method of claim 1 , wherein the therapeutically effective amount is the amount required to increase cytosolic calcium levels and perturb ER in cells of the subject.

7. The method of claim 1 , wherein the therapeutically effective amount is an amount effective to potentiate ER stress and unfolded protein response (UPR) in cells of the subject.

8. The method of claim 1 , the glycosylation-defective protein associated disease or disorder is a human cystic fibrosis transmembrane conductance regulator (CFTR) protein defect related disease or disorder.

9. The method of claim 7 , the hCFTR defect related disease or disorder is a ΔF508CFTR mutation related disease or disorder.

10. The method of claim 1 , the SERCA inhibitor being administered to the subject by at least one of ophthalmic, topical, parenteral, subcutaneous, intravenous, intraarticular, intrathecal, intramuscular, intraperitoneal, intradermal, transdermal, buccal, oromucosal, oral, or inhalation administration.

11. A method of treating cystic fibrosis associated with a ΔF508CFTR mutation of human cystic fibrosis transmembrane conductance regulator (CFTR) protein in a subject in need thereof, the method comprising:

administering to the subject a therapeutically effective amount of a Sarco/ER ATPase (SERCA) inhibitor.

12. The method of claim 11 , wherein the SERCA inhibitor reduces endoplasmic reticulum luminal calcium levels.

13. The method of claim 11 , wherein the SERCA inhibitor induces activation of the GRASP55 cargo dependent unconventional secretory pathway (GCUSP).

14. The method of claim 11 , the SERCA inhibitor selected from the group consisting of Artemisinin, Artesunate (Arts), thapsigargin, mipsagargin, DBHQ (2,5-di-tert-butylhydroquinone), Saikosaponin-d (Ssd), SBF-1, ruthenium red, curcumin, F36, gingerol, paxilline, cyclopiazonic acid, sHA14-1, CXL017, and analogs thereof.

15. The method of claim 14 , the SERCA inhibitor comprising Artesunate (Arts).

16. The method of claim 11 , wherein the therapeutically effective amount is the amount required to increase cytosolic calcium levels and perturb ER in cells of the subject.

17. The method of claim 11 , wherein the therapeutically effective amount is an amount effective to potentiate ER stress and unfolded protein response (UPR) in cells of the subject.

18. The method of claim 11 , the SERCA inhibitor being administered to the subject by at least one of ophthalmic, topical, parenteral, subcutaneous, intravenous, intraarticular, intrathecal, intramuscular, intraperitoneal, intradermal, transdermal, buccal, oromucosal, oral, or inhalation administration.
