In mice, Ptcl haploinsufficiency and disruption of DNA repair (DNA ligase IV inactivation) or cell cycle regulation (Kipl, Ink4d, or Inkd.c inactivation), in conjunction with p53 dysfunction, predispose to medulloblastoma. To identify genes important for this tumor, we evaluated gene expression profiles in medulloblastomas from these mice. Unexpectedly, medulloblastoma展开更多

Experimental Design: After central pathology review, the incidence of ERBB1 amplification and overexpression was determined in 28 samples (18 surgical biopsy and 10 postmortem specimens) of BSG using quantitative PCR and immunohistochemistry,展开更多
