Angstrom6 (A6 Peptide) is an 8 amino-acid peptide derived from single-chain urokinase plasminogen activator (scuPA) and interferes with the uPA/uPAR cascade and abrogates downstream effects. Angstrom6 binds to CD44 resulting in the inhibition of migration, invasion, and metastasis of tumor cells, and the modulation of CD44-mediated cell signaling.
体外研究
Angstrom6 is effective at blocking the migration of the OVCAR8, OVCAR3, ES2, IGROV-1, MDA-MB-468, and MDA-MB361 cells with IC50s in the range of 10 to 100 nM.
Angstrom6 potentiates the CD44-dependent adhesion of cancer cells to hyaluronic acid and activated CD44-mediated signaling, as evidenced by focal adhesion kinase and MAP/ERK kinase phosphorylation.
