title: Estrogen and MYB in breast cancer: potential for new therapies.
abstract: MYB is highly expressed in almost all estrogen receptor (ER)-positive breast tumours and is a direct target of estrogen/ER signalling. Our recent studies have shown that MYB is also required for the proliferation of ER-positive breast tumour cell lines, and have shed further light on the mechanism of ER regulation of MYB expression. Here we discuss the rationale for therapeutic targeting of MYB in breast cancer and consider a number of approaches to developing an anti-MYB therapeutic.
