Gene-targeted deletion of individual Src kinases protects against tumor cell extravasation. (A–C) Tumor burden, computed as the increase in lung/heart weight ratio over that for normal mice, was measured 12 d after i.v. inoculation with metastatic tumor cells. Mice lacking Src (A) or Yes (B and C) are protected from experimental pulmonary metastasis of CT26 (A and B) or D121 (C) cells. (D) This phenomenon is not specific to the lung, because Yes-deficient mice are also protected from experimental hepatic metastasis of CT26 or D121 cells. (E) Growth of primary tumors on the flank is not different between genotypes for CT26 or D121 cells. (F) Mice lacking Fyn, which show a normal vascular permeability response to VEGF, are not protected from metastasis. * indicates P < 0.05; n = 8 each bar. Bar, 1 mm.
