Anti-invasive and anti-adhesive activities of a recombinant disintegrin, r-viridistatin 2, derived from the Prairie rattlesnake (Crotalus viridis viridis).


ABSTRACT: Snake venom disintegrins inhibit platelet aggregation and have anti-cancer activities. In this study, we report the cloning, expression, and functional activities of a recombinant disintegrin, r-viridistatin 2 (GenBank ID: JQ071899), from the Prairie rattlesnake. r-Viridistatin 2 was tested for anti-invasive and anti-adhesive activities against six different cancer cell lines (human urinary bladder carcinoma (T24), human fibrosarcoma (HT-1080), human skin melanoma (SK-Mel-28), human colorectal adenocarcinoma (CaCo-2), human breast adenocarcinoma (MDA-MB-231) and murine skin melanoma (B16F10)). r-Viridistatin 2 shares 96% and 64% amino acid identity with two other Prairie rattlesnake medium-sized disintegrins, viridin and viridistatin, respectively. r-Viridistatin 2 was able to inhibit adhesion of T24, SK-MEL-28, HT-1080, CaCo-2 and MDA-MB-231 to various extracellular matrix proteins with different affinities. r-Viridistatin 2 decreased the ability of T24 and SK-MEL-28 cells to migrate by 62 and 96% respectively, after 24 h of incubation and the invasion of T24, SK-MEL-28, HT-1080 and MDA-MB-231 cells were inhibited by 80, 85, 65 and 64% respectively, through a reconstituted basement membrane using a modified Boyden chamber. Finally, r-viridistatin 2 effectively inhibited lung colonization of murine melanoma cells in BALB/c mice by 71%, suggesting that r-viridistatin 2 could be a potent anti-cancer agent in vivo.
