GSK1838705A suppresses glioma tumor growth and induces apoptosis in vivo. (A) Following inoculation of U87MG cells, formulated vehicle control or GSK1838705A (4 and 8 mg/kg) was injected into the corresponding group of nude mice (n=6/group) once daily.

Starting on day 7, the differences between the treatment groups (4 and 8 mg/kg) and the vehicle control group were significant (P<0.05). (B) Body weights of the mice during the course of treatment were measured as an indication of significant cytotoxic effects. The data are expressed as the mean ± standard deviation. No significant differences are observed between any two of the groups during the course of treatment. (C) At the end of treatment, the tumors were harvested.
