简介内容:A20FMDV2, a peptide derived from the α-helical RGD cell-interacting domain of the VP1 capsid protein of foot-and-mouth disease virus (FMDV) serotype O, targets and binds αVβ6 integrin. It effectively disrupts αVβ6 integrin-mediated cell adhesion in H357 tongue squamous cell carcinoma cells that exhibit human αVβ6, with an inhibitory concentration (IC50) of ?M. Additionally, when labeled with 111indium-DTPA, A20FMDV2 (20 MBq) specifically attaches to αVβ6 integrin in a breast cancer mouse xen
