Project description:Histologically normal breast epithelium and stroma were laser capture microdissected from breast reduction specimens and from specimens of invasive ductal carcinoma. The objective of the study was to compare normal reduction tissues to tissues adjacent to I.D.C. to determine whether adjacent normal tissues contained expression profiles correlated with characteristics of the primary tumor and to identify markers of normal epithelium and stroma. Keywords: disease state analysis

Experiment Overall Design: common reference design. 66 samples replicated twice as dye swaps generating 132 arrays.
Project description:As part of the RATHER (RAtional THERapy for breast cancer: individualized treatment for difficult-to-treat breast cancer subtypes) consortium, expression profiling of 144 untreated primary invasive lobular carcinoma (ILC) breast cancer tissues and 15 ILC cell lines was performed using microarray.
