Figure 5. Decrease in growth of Vhl-/- tumors.
A: Teratocarcinomas were created by injecting VhV-/-, Vhl-/-.1, and Vhl-/-.2 ES cells subcutaneously into nude mice. Vhl-/- tumors ranged in size but were considerably smaller than Vhl+/- derived tumors. B: Rate of tumor growth was measured by tumor volume for 21 days. C: Graph represents the combined results of three separate experiments in which the masses of Vhl+/+, Vhl-/-, and Vhl-/-.1 + HA-VHL tumors after 21 days of growth were measured. N values are as indicated and bars represent standard error. Vhl-/- tumors were significantly smaller than Vhl+/- derived tumors. Genetically rescued Vhl-/-.1 + HA-VHL tumors grew similarly to Vhl+/- tumors. Student t-test revealed a statistically significant difference between tumor masses, p=0.003.
