A collection of breast cancer cell lines for the study of functionally distinct cancer subtypes
by:In: Cancer Cell, Vol. 10, Nr. 6
(2006)
, p. 515--527.
Abstract
Recent studies suggest that thousands of genes may contribute to
breast cancer pathophysiologies when deregulated by genomic or
epigenomic events. Here, we describe a model ``system'' to appraise
the functional contributions of these genes to breast cancer
subsets. In general, the recurrent genomic and transcriptional
characteristics of 51 breast cancer cell lines mirror those of 145
primary breast tumors, although some significant differences are
documented. The cell lines that comprise the system also exhibit
the substantial genomic, transcriptional, and biological
heterogeneity found in primary tumors. We show, using Trastuzumab
Herceptin monotherapy as an example, that the system can be used
to identify molecular features that predict or indicate response to
targeted therapies or other physiological perturbations.
