Fig 1: Western blots of selected proteinsCell lysates obtained from cultures of primary mammary epithelial cells for women having normal breast reduction (control) or prophylactic breast reduction (high-risk women) surgeries were immunoblotted with FAK (PTK2), ITGA6, ICAM2, p53, PTEN, ITGA IV, ITGA V, VTN, F-actin, and ß-actin (loading control). Two lysates were loaded to each gel to compare between blots. Sample names shown in black are from high-risk women; sample names shown in blue are from normal breast reduction samples; sample names shown in red are from breast reduction normal controls placed on every gene to serve as internal loading/processing controls.
