Biochem/physiol Actions
Acetyl Ser-Asp-Lys-Pro is formed in bone marrow cells by enzymatic processing of thymosin β4. It inhibits the entry of pluripotent hemopoietic stem cells into S-phase of the cell cycle and protects against Ara-C lethality in mice. It is a specific substrate for the N-terminal active site of angiotensin converting enzyme, which is responsible for its degradation in vivo.

The natural tetrapeptide acetyl-ser-asp-lys-pro (AcSDKP) is formed in vivo by enzymatic cleavage of the N terminus of thymosin beta4 by prolyl oligopeptidase (POP). Recently, AcSDKP was shown to promote angiogenesis. Because of the critical role of neovascularization in cancer development

It has been reported that N-acetyl-seryl-aspartyl-lysyl-proline (Ac-SDKP) attenuates renal and cardiac inflammation as well as fibrosis in hypertensive rats. In this study, we investigated these effects using a unilateral ureteral obstruction (UUO) model. Eighteen male Wistar rats were randomly divided

Cardiovascular disease (CVD) is responsible for ∼27% of deaths worldwide, with 80% of these occuring in developing countries. Hypertension is one of the most important treatable factors in the prevention of CVD. Angiotensin-I converting enzyme (ACE) is a two-domain dipeptidylcarboxypeptidase

N-acetyl-seryl-aspartyl-lysyl-proline (Ac-SDKP) inhibits collagen production and cell proliferation in cultured rat cardiac fibroblasts, but its effect on differentiation of fibroblasts into myofibroblasts is not known. High amounts of transforming growth factor-beta1 (TGF-beta1) have been found in fibrotic cardiac tissue. TGF-beta1

Angiotensin-converting enzyme (ACE), an important part of the renin-angiotensin system, is implicated in stimulating the fibrotic processes in the heart, lung, liver and kidney, while an ACE inhibitor (ACEI) promotes physiological tissue repair in these organs. The mechanism is closely
