acidic peptide/infarction

Thirty percent of global mortalities are caused by cardiovascular disease, and 54% of the aforementioned amount is instigated by ischemic heart disease that triggered myocardial infarction. Myocardial infarction is due to blood flow cessation in certain coronary arteries that causes lack of oxygen

Monoclonal antibodies are widely used analytical tools in biochemical research. The knowledge of their corresponding epitopes is of major interest. One possible approach for epitope characterization is the application of protein antigen proteolysis in combination with mass spectrometric peptide

Thymosin beta4 (Tbeta4) is a developmentally expressed 43-amino acid peptide that inhibits organization of the actin-cytoskeleton by sequestration of G-actin monomers. Tbeta4 improves cardiac function after myocardial infarction in adult mice and promotes healing properties in both dermal and

Thymosin beta 4 (Tbeta4) is a highly conserved, 43-amino acid acidic peptide (pI 4.6) that was first isolated from bovine thymus tissue over 25 years ago. It is present in most tissues and cell lines and is found in high concentrations in blood platelets, neutrophils, macrophages, and other lymphoid

Cardiovascular function is modulated by neuronal transmitters, circulating hormones, and factors that are released locally from tissues. Urotensin II (UII) is an 11 amino acid peptide that stimulates its' obligatory G protein coupled urotensin II receptors (UT) to modulate cardiovascular function in

The active incretin hormone glucagon-like peptide-1(7-36)amide (GLP-1) is a 30-amino acid peptide that exerts glucoregulatory and insulinotropic actions by functioning as an agonist for the GLP-1 receptor (GLP-1R). In addition to its anti-diabetic effects, GLP-1 has demonstrated cardioprotective

NGF (nerve growth factor) and BDNF (brain-derived neurotrophic factor) are protein molecules (MW 26 and 13.6 kDa, respectively) that are neuroprotective in the middle cerebral artery occlusion (MCAO) rat stroke model. Their mechanism of action involves the activation of transcription factor AP-1

Oligodendrocytes are the predominant cell type in white matter and are highly vulnerable to ischemic injury. The role of oligodendrocyte dysfunction in ischemic brain injury is unknown. In this study, we used a 24-amino acid peptide S14G-Humanin (HNG) to examine oligodendrogenesis and neurological

Entrapment of lipoprotein particles in the extracellular matrix of the arterial intima is a characteristic feature of the development of atherosclerosis, the disease behind myocardial infarction and stroke. In this study, sugars were exploited in the separation of lipoproteins by CE.

Activation of the formyl-peptide receptor-like (FPRL) 1 pathway has recently gained high recognition for its significance in therapy of inflammatory diseases. Agonism at FPRL1 affords a beneficial effect in animal models of acute inflammatory conditions, as well as in chronic inflammatory diseases.

Endothelin-1 (ET-1) is the most potent vasoconstrictor yet described. The active 21-amino-acid peptide is derived from the conversion of the inactive precursor "Big ET-1" by an enzyme called endothelin-converting enzyme. In addition to its potent action as a vasoconstrictor, endothelin promotes

BACKGROUND The RGD-toxin protein Lj-RGD3 is a naturally occurring 118 amino acid peptide that can be obtained from the salivary gland of the Lampetra japonica fish. This unique peptide contains 3 RGD (Arg-Gly-Asp) motifs in its primary structure. Lj-RGD3 is available in recombinant form (rLj-RGD3)

Endothelial cells are a rich source of a variety of vasoactive substances, which either cause vasodilation or vasoconstriction. Important endothelium-derived vasodilators are prostacyclin, bradykinin, nitric oxide and endothelium-derived hyperpolarizing factor. In particular, nitric oxide inhibits

Endothelin, a 21-amino-acid peptide, binds to a specific receptor on vascular smooth muscle cells, thereby inducing vasoconstriction. Although plasma levels are not consistently elevated in hypertension, there is evidence that endothelin has an important role in its pathogenesis. Administration of

Thymosin beta 4 (Tβ4) is a 43-amino-acid peptide with protective properties in myocardium injury. Previously, we produced a recombinant human dimeric Tβ4 (DTβ4). Here, the cardioprotective effects of DTβ4 and the molecular mechanisms underlying its enhanced activity were
