Inhibition of MDA-MD-435 breast carcinoma growth by anastellin, sFN,
and sFBG. Nude mice bearing s.c. tumors from MDA-MB-435 breast
carcinoma cells were used in a treatment experiment similar to the one
shown in Fig. 3. The doses per injection were as follows: anastellin,
600 μg; sFN, 100 μg of fibronectin mixed with 300 μg of
anastellin; sFBG, 500 μg of fibrinogen mixed with 300 μg of
anastellin; III-11C, 600 μg. Six mice were used per group. The tumors
were significantly smaller at the end of the experiment in the mice
treated with anastellin (P < 0.01), sFN
(P < 0.001), or sFBG (P <
0.001) than in the mice treated with vehicle alone or with III-11C.
