Estrogen receptor positive (ER+) breast cancers often have MDM2 overexpression indicating a critical role for MDM2 in breast cancer tumorigenesis. The cancer genome atlas (TCGA) found that increased MDM2 expression is one of the four pathways that correlate with all breast cancer subtypes. MDM2 is mainly known as the negative regulator of wild type p53. However, aggressive breast cancers often have MDM2 overexpression and mutant p53 (mtp53). We previously reported that MDM2 provides an estrogen-mediated proliferative advantage to MCF-7 breast cancer cells (ER+, MDM2 overexpression, wild type p53), independent of wild type p53 in both 2D and 3D culture conditions. …
