The smallest source of variation is the between-breast component, implying that normal material from a contralateral breast is a good surrogate for normal material from the affected breast.
We observed a significantly higher relative expression of ERD5 messenger RNA in breast tumor components compared with matched adjacent normal breast tissue.
A higher relative expression of ERD3 messenger RNA in the normal breast tissue components compared with adjacent neoplastic tissue was found in the ER-positive subgroup.
The investigative approach was designed to detect and quantify the three molecules in specific breast tissue components, data that were not previously available.
This novel observation might link good response to tamoxifen to reformation of normal breast tissue components, such as cell-cell junctions (Lanigan et al., 2009).
These and other advantages have been linked to breast milk components, including fatty acids [ 1], growth factors [ 2], immunological factors [ 3, 4], live maternal cells [ 5, 6] and some genetic materials [ 7, 8].
There is clearly a need for an improved understanding of the specific factors that are involved in these processes and of the role played by the several breast tissue components that contribute to density.

These findings strongly suggest that DMBT1 is one of the various breast milk components with functions in innate immunity, where it may function as a pattern-recognition molecule for pathogens and would co-localize with various of its known binding partners such as sIgA or lactoferrin.
A trend toward a higher relative expression of ERD3 messenger RNA in the normal breast tissue components compared with adjacent neoplastic tissue was found (10 out of 13 cases), which reached statistical significance when the ER-positive subgroup only was considered.
