产品介绍
N-Acetyl-Ser-Asp-Lys-Pro 通过酶促处理胸腺素 β4 在骨髓细胞中形成。 它抑制多能造血干细胞进入细胞周期的 S 期,并防止小鼠中的 Ara-C 致死性。

产品描述

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.

体外活性

N-Acetyl-Ser-Asp-Lys-Pro (AcSDKP) is a specific substrate for the N-terminal site of ACE and increases 5-fold during ACE inhibitor therapy.??AcSDKP inhibited the proliferation of isolated cardiac fibroblasts (P<0.05) but significantly stimulated the proliferation of vascular smooth muscle cells.?Flow cytometry of rat cardiac fibroblasts treated with AcSDKP showed significant inhibition of the progression of cells from G0/G1 phase to S phase of the cell cycle.?In cardiac fibroblasts transfected with a Smad-sensitive luciferase reporter construct, AcSDKP decreased luciferase activity by 55+/-9.7% (P=0.01).?Moreover, phosphorylation and nuclear translocation of Smad2 was decreased in cardiac fibroblasts treated with AcSDKP.?To conclude, AcSDKP inhibits the growth of cardiac fibroblasts and also inhibits TGFbeta1-stimulated phosphorylation of Smad2.?Because AcSDKP increases substantially during ACE inhibitor therapy, this suggests a novel pathway independent of angiotensin II, by which ACE inhibitors can inhibit cardiac fibrosis.
