Wnt signalling in normal breast cell lines (N), ER-ve (T−) and ER+ve (T+) breast cancer cell lines.

<p>A) mRNA expression was normalised to house keeper genes. Cluster analysis was performed and data displayed in a heatmap: decreased (green) or increased (red) expression compared to the mean mRNA expression. (Red) ↑↑ Indicates significant increased expression (<0.05) (red) ↑ indicates a trend towards increased expression. (Green) Indicates significant increased expression (<0.05) (green) indicated a trend towards increased expression. B) Protein expression of Lef 1 and B-actin (housekeeper) in normal breast cell lines (N), ER-ve (T−) and ER+ve (T+) breast cancer cell lines.
