rLj-RGD3 is a new recombinant RGD-toxin protein with 3 RGD motifs and is secreted from the buccal glands of Lampetra japonica. rLj-RGD3 suppresses human pancreatic carcinoma Panc-1 cell-derived tumors in nude mice. rLj-RGD3 exhibits pro-apoptotic effects that are regulated by the intrinsic apoptotic pathway. The effect of rLj-RGD3 on anti-angiogenesis is mediated via the FAK/PI3K/Akt signaling pathway.
