title: [Advances in study of murine double minute 2/p53 passway with breast cancer].
abstract: Mutant or aberrant regulation of expressing products of p53 gene results in losing its tumor suppressive function, which is often seen in many malignancies, including breast cancer. Oncoprotein MDM2 plays a primary role in regulating P53, and these two form an automregulatory feedback loop. mdm2/p53 passway performs important function in development, progression,therapy and prognosis of breast cancer. Besides, more and more studies show that some other molecular markers in breast cancer, such as PI3K/Akt/mTOR, p14ARF, and Her2/neu can regulate this passway unneglectedly. The purpose of this review is to summarize not only the relations between mdm2/p53 passway and pathological characters, therapy and prognosis of breast cancer, but also the relations of this passway with some other molecular proteins in breast cancer.
