Methods and compositions for the prevention or treatment of barth syndrome
The disclosure provides methods of preventing or treating Barth Syndrome in a mammalian subject, reducing risk factors associated with Barth Syndrome, and/or reducing the likelihood or severity of Barth Syndrome. The methods comprise administering to the subject an effective amount of an aromatic-cationic peptide to increase expression of TAZ1 in subjects in need thereof.
1. A method for stabilizing cardiolipin remodeling in a mammalian subject having or suspected of having Barth Syndrome comprising administering to the subject a therapeutically effective amount of the peptide D-Arg-2′6′-Dmt-Lys-Phe-NH 2 or a pharmaceutically acceptable salt thereof, wherein the mammalian subject has decreased expression of TAZ1 compared to a normal control subject.
2. The method of claim 1 , wherein the cardiolipin is 18:2 species of cardiolipin.
3. The method of claim 1 , wherein the subject is human.
4. The method of claim 1 , wherein the peptide is administered orally, topically, systemically, intravenously, subcutaneously, intraperitoneally, or intramuscularly.
5. The method of claim 1 , further comprising separately, sequentially or simultaneously administering a cardiovascular agent to the subject.
6. The method of claim 1 , wherein the pharmaceutically acceptable salt comprises acetate or trifluoroacetate salt.
