Figure 4. PTEN Reconstitution alters cell responses to anti-HGF therapeutics in orthotopic glioma xenografts.
Animals bearing U87-tetPTEN intracranial xenografts were treated ± doxycycline (2 mg/mL in drinking water) for 6 days with either anti-HGF or control mAb 5G8 (1.25mg/kg i.p.) for 6 days. Intracranial tumor xenograft sections were analyzed for tumor volume (A), cell proliferation (B), angiogenesis (C), and apoptosis (D) as described in Materials and Methods. *** = P < 0.001 compared to controls, * = P < 0.05 compared to controls, L2G7 alone or Doxy alone ** = P < 0.01 compared to control, L2G7 alone or Doxy alone
