Alterations of the epidermal growth factor receptor (EGFR) occur frequently in malignant gliomas through gene amplification or rearrangement, especially in a large fraction of de novo type glioblastomas. The most common of these mutant EGFRs (variously named de2-7 EGFR, ΔEGFR or EGFRvIII) lacks a portion of the extracellular ligand-binding domain. Here, we review the evidence that shows that expression...
The PCAF gene encodes the p300/CBP-Associated Factor (PCAF), a histone acetyltransferase, which regulates p53 by acetylation of Lys320 in the C-terminal portion of p53. While the p53 gene is one of the most frequently mutated tumor suppressor genes in human tumors, such mutations occur in only 30% of astrocytic tumors. Since PCAF can regulate p53 activity, abrogation of PCAF function by PCAF gene...
