mortality/aging
premature death ( J:149662 )
• all mice die prior to 200 days

neoplasm
increased glioma incidence ( J:149662 )
• 70% of gliomas exhibit necrosis, a feature of human glioblastoma multiforme
• tumors are relatively homogeneous histological and in lineage marker expression
decreased tumor latency ( J:149662 )
• all mice develop astrocytic gliomas with shorter latency than observed in Trp53tm1Elee/Trp53tm1Tyj Tg(GFAP-cre)25Mes or Trp53tm1Elee/ Trp53tm1Elee Tg(GFAP-cre)25Mes mice

nervous system
increased glioma incidence ( J:149662 )
• 70% of gliomas exhibit necrosis, a feature of human glioblastoma multiforme
• tumors are relatively homogeneous histological and in lineage marker expression
