A consortium of researchers have identified the gene expression patterns of breast cancer stem cells that remain post treatment with either chemotherapy or antihormone treatments. They report that this gene signature differs from those linked to the bulk of epithelial cells in the tumor.Based on: Gene signature for cancer stem cells may provide drug targets, Glenna Picton, News Release, Baylor College of Medicine, August 4, 2009.

A subset of tumour cells that remain after a woman with breast cancer undergoes treatment with either anti-cancer or anti-hormone therapy shows a 'gene signature' that could be used to define targets for developing new drugs against the disease, said a consortium of researchers led by Baylor College of Medicine. The report appears in the current issue of the Proceedings of the National Academy of Sciences.The report referred to in the above excerpt is an Open Access publication: Residual breast cancers after conventional therapy display mesenchymal as well as tumor-initiating features by Chad J Creighton and 22 co-authors, including Michael T Lewis, Jeffrey M Rosen and Jenny C Chang, Proc Natl Acad Sci USA 2009(Aug 3).
