The role of a single nucleotide polymorphism of MDM2 in glioblastoma multiforme.

Abstract excerpt

OBJECT: Glioblastoma multiforme (GBM) is the most common primary brain tumor in adults, with a 5-year survival rate of < 5%. Aberrant function of TP53 is common in GBM. Although mutational inactivation of p53 is found in many cases, there remain tumors in which genetic alterations of p53 are absent. Negative regulators of the TP53 pathway such as MDM2, which directly inhibits TP53 expression and activity, may...
