Abstract: Disclosed herein are compositions of GHRH agonists and peptides, and methods to treat disorders, such as ischemia and reperfusion injury. In one embodiment, a method of treating a reperfusion injury in a subject in need may involve administering a therapeutically effective amount of at least one GHRH agonist peptide to the subject. In additional embodiment, a method of promoting vasculogenesis in a mammal may involve administering a therapeutically effective amount of at least one GHRH agonist peptide to the subject. In a further embodiment, a method of promoting differentiation of mesenchymal stem cells into endothelial cells may involve contacting mesenchymal stem cells with at least one GHRH agonist peptide.

Abstract: There is provided a novel series of synthetic analogs of hGH-RH(1-29)NH2 (SEQ ID NO: 1) and hGH-RH(1-30)NH2. Of particular interest are those carrying PhAc, N-Me-Aib, Dca, Ac-Ada, Fer, Ac-Amc, Me-NH-Sub, PhAc-Ada, Ac-Ada-D-Phe, Ac-Ada-Phe, Dca-Ada, Dca-Amc, Nac-Ada, Ada-Ada, or CH3—(CH2)10—CO-Ada, at the N-Terminus and ?-Ala, Amc, Apa, Ada, AE2A, AE4P, ?-Lys(?-NH2), Agm, Lys(Oct) or Ahx, at the C-terminus. These analogs inhibit the release of growth hormone from the pituitary in mammals as well as inhibit the proliferation of human cancers, and inhibit the hyperplastic and benign proliferative disorders of various organs, through a direct effect on the cancerous and non-malignant cells. The stronger inhibitory potencies of the new analogs, as compared to previously described ones, result from replacement of various amino acids.

Abstract: Disclosed herein are compositions of GHRH agonists and peptides, and methods to treat diabetes. In one embodiment, a method of promoting survival of grafted cells and/or tissues may involve exposing the cells and/or tissues to an effective amount of at least one agonist of GHRH. In some embodiments, the grafted cells and/or tissues may be pancreatic cells. In some embodiments, the grafted cells may be islet cells co-cultured with non-pancreatic cells. In a further embodiment, a method of treating a patient diagnosed with diabetes involves transplanting and/or grafting the islet cells and/or tissues comprising islet cells into a patient, and administering a therapeutically effective amount of at least one agonist of GHRH to the patient. In some embodiments, the islet cells and/or tissues comprising islet cells may be optionally exposed to GHRH and/or at least one agonist of GHRH prior to transplantation into a patient.
