A method of treatment for treating, preventing, inhibiting or reducing tissue deterioration, injury or damage due to congestive heart failure disease, or for restoring tissue adversely affected by said disease, in a subject, includes administering to a subject an effective amount of a composition including a peptide agent including amino acid sequence LKKTET SEQ ID NO: 1 or LKKTNT SEQ ID NO: 2, a conservative variant thereof, or a peptide agent that stimulates production of an LKKTET SEQ ID NO: 1 or LKKTNT SEQ ID NO: 2 peptide, or a conservative variant thereof, in the tissue.

1. A method of treatment for treating, preventing, inhibiting or reducing tissue deterioration, injury or damage due to congestive heart failure disease, or for restoring tissue adversely affected by said disease, in a subject, comprising administering to a subject having congestive heart failure disease an effective amount of a composition comprising a peptide agent comprising amino acid sequence LKKTET (SEQ ID NO: 1) or a conservative variant thereof, LKKTNT (SEQ ID NO: 2) or a conservative variant thereof, Thymosin β4 (Tβ4), a Tβ4isoform, KLKKTET (SEQ ID NO: 3), LKKTETQ (SEQ ID NO: 4), oxidized Tβ4, an N-terminal variant of Tβ4, a C-terminal variant of Tβ4, Tβ4ala, Tβ9, Tβ10, Tβ11, Tβ12, Tβ13, Tβ14, Tβ15, gelsolin, vitamin D binding protein (DBP), profilin, cofilin, depactin, DNasel, vilin, fragmin, severin, capping protein, β-actinin or acumentin, in said tissue, so as to inhibit said tissue deterioration, injury or damage due to said disease, or restore tissue adversely affected by said disease, wherein administration of said peptide agent results in at least one of a reduction of left ventricular systolic pressure (LVSP) of a heart, reduction in left ventricular end diastolic pressure (LVEDP) of a heart, attenuation of left ventricular end systolic volume of a heart, attenuation of left ventricular end diastolic volume of a heart, an increase in rate of change (velocity) in left ventricular pressure-rise with time (dP/dt) of a heart, an increase in rate of change (velocity) in left ventricular pressure decrease with time (pdP/dt) of a heart, attenuation of pulmonary edema following heart muscle damage/injury, or attenuation of muscle thickness of a heart left ventricle. 2. The method of claim 1, wherein said tissue deterioration, injury or damage comprises at least one of an increase in heart size or mass, increase in size or mass of heart tissue, thickening of heart muscle, or pulmonary edema. 3. The method of claim 2 wherein said peptide agent is Tβ4. 4. The method of claim 2 wherein said peptide agent is other than Tβ4. 5. The method of claim 2 wherein said peptide agent is other than oxidized Tβ4. 6. The method of claim 4 wherein said peptide agent comprises amino acid sequence KLKKTET (SEQ ID NO: 3), amino acid sequence LKKTETQ (SEQ ID NO:4), and N-terminal variant of Tβ4, a C-terminal variant of Tβ4, or an isoform of Tβ4. 7. The method of claim 2 wherein said peptide agent is administered to said subject at a dosage within a range of about 1-30 micrograms. 8. The method of claim 2 wherein said agent is administered by direct administration to said tissue, or by intravenous, intraperitoneal, intramuscular, subcutaneous, inhalation, transdermal or oral administration, to said subject. 9. The method of claim 2 wherein said composition is administered systemically. 10. The method of claim 2 wherein said composition is administered directly. 11. The method of claim 2 wherein said composition is in a form of a solution, gel, cream, paste, lotion, spray, suspension, dispersion, salve, hydrogel, ointment, foam or oil. 12. The method of claim 2 wherein said peptide agent is a recombinant or synthetic peptide. 13. A method for screening for a stimulating agent that stimulates production of a peptide agent comprising amino acid sequence LKKTET (SEQ ID NO: 1) or a conservative variant thereof, LKKTNT (SEQ ID NO: 2) or a conservative variant thereof, Thymosin β4 (Tβ4), a Tβ4isoform, KLKKTET (SEQ ID NO: 3), LKKTETQ (SEQ ID NO: 4), oxidized Tβ4, an N-terminal variant of Tβ4a C-terminal variant of Tβ4, Tβ4ala, Tβ9, Tβ10, Tβ11, Tβ12, Tβ13, Tβ14, Tβ15, gelsolin, vitamin D binding protein (DBP), profilin, cofilin, depactin, DNasel, vilin, fragmin, severin, capping protein, β-actinin or acumentin, comprising contacting a tissue exhibiting congestive heart failure disease, with a candidate compound; and measuring activity in said tissue of said peptide agent, wherein an increase of activity of said peptide agent in said tissue, compared to a level of activity of said peptide agent in a corresponding tissue lacking said candidate compound, indicates that said compound is capable of stimulating production of said peptide agent. 14. The method of claim 13 wherein said peptide agent is thymosin beta 4. 15. The method of claim 1, wherein said peptide agent is administered acutely, chronically, or a combination thereof.
