The disclosure provides methods of reducing MMP-9 expression and/or MMP-9 activity in a mammalian subject. The disclosure also provides methods of increasing TIMP-1 expression and/or TIMP-1 activity in a mammalian subject. The methods comprise administering a therapeutically effective amount of an aromatic-cationic peptide to a subject in need thereof.

Methods for the regulation of matrix metalloproteinase expression

The invention provides methods of preventing or treating cardiac ischemia-reperfusion injury in a mammalian subject. The methods provide administering aromatic-cationic peptides in effective amounts to prevent or treat an anatomic zone of no re-flow in mammalian subjects. The methods comprise administering to the subject an effective amount of an aromatic-cationic peptide to subjects in need thereof.

Methods for the prevention or treatment of no-reflow following ischemia/reperfusion injury

The disclosure provides methods and compositions for increasing SERCA2a expression levels in a mammalian subject in need thereof. The methods comprise administering to the subject a therapeutic amount of an aromatic-cationic peptide to subjects in need thereof. In some embodiments, the aromatic-cationic peptide is D-Arg-2'6&#x2032;-Dmt-Lys-Phe-NH2, or a pharmaceutically acceptable salt thereof such as acetate or trifluoroacetate salt. In some embodiments, the subject has suffered a myocardial infarction.

Methods and compositions for regulating SRCA2A expression levels in myocardial infarction

A method for treating the heart and associated vessels and tissues, by controlling the temperature of the pericardial space and/or introducing therapeutic agents, drugs or the like thereto, includes providing a fluid, liquid(s), gas(es) or mixtures thereof, with or without therapeutic agents, drugs or the like, and heating and/or cooling, this fluid. At a time proximate to the heating and/or cooling of the fluid, the pericardial space is accessed by pericardiocentesis, such that the pericardium is punctured and the pericardial space is instrumentized at a location, and in particular, a location where treatment is desired. The heated and/or cooled fluid is then delivered to the pericardial space. At a time after delivery, the fluid is withdrawn from the pericardium, through either the same catheter, or through another catheter at different point along the pericardium, that was also instrumentized (catheterized) by standard pericardiocentesis procedures. This delivery and withdrawal of the fluid may be coordinated, so as to form a circuit.
