Steps solidifying a role for SEPT9 in breast cancer suggest that greater strides are needed

Abstract

Septins comprise a conserved family of GTPase proteins. Of these, human SEPT9 has been widely implicated in cancers of epithelial origin, including breast cancer, as well as leukemia. In a previous issue of Breast Cancer Research, Connolly and colleagues present compelling data further supporting a role for SEPT9 isoforms in early breast cancer development as well as evidence suggesting that cellular localization patterns of SEPT9 isoforms may contribute to oncogenesis. © 2012 BioMed Central Ltd.
