生物活性

製品説明 ATN-161 is a novel small peptide antagonist of integrin α5β1. It binds to several integrins, including α5β1 and αvβ3, that play a role in angiogenesis and tumor progression.
in vitro ATN-161 interacts with the N-terminus of the β1-domain of integrin α5β1, which may lock this integrin in an inactive conformation[2]. ATN-161 treatment up to 100 μmol/L shows no significant effect on tumor cell proliferation compared with the vehicle-treated control group of cells. However, ATN-161 significantly inhibits MAPK phosphorylation with maximal effects observed at 20 μmol/L of ATN-161 after 30 minutes of treatment[1].
in vivo ATN-161 (Ac-PHSCN-NH2), a 5-mer capped peptide derived from the synergy region of fibronectin that binds to α5β1 and αvβ3 in vitro, blocks breast cancer growth and metastasis. Treatment with ATN-161 causes a significant dose-dependent decrease in tumor volume and either completely blocked or caused a marked decrease in the incidence and number of skeletal as well as soft tissue metastases. Treatment with ATN-161 results in a significant decrease in the expression of phosphorylated mitogen-activated protein kinase, microvessel density, and cell proliferation in tumors grown in vivo[1]. ATN-161 is a peptide with a fairly short plasma half-life. compared with the plasma pharmacokinetics of ATN-161, It is cleared from the tumor with much slower kinetics supporting the hypothesis that this peptide exerts its effects through a durable interaction with its target(s)in the tumor[3].

実験の流れ

MDA-MB-231 (1 × 106) cells are plated in 100 mm Petri dishes for 24 hours, then serum-starved overnight before treatment with vehicle or ATN-161 (1-100 μmol/L) for different time periods (15-60 minutes). Western blot analyses are carried out using antibodies against focal adhesion kinase, phosphorylated FAK, mitogen-activated protein kinase (MAPK), phosphorylated MAPK, and β-tubulin as previously described. Western blots are detected using enhanced chemiluminescence detection reagents.
