Examples of differential expression of cytoskeletal proteins. Representative sections of 2DGE images (left panel) and representative Western blots (right panel) for vinculin (VCL) (A) and four and a half LIM domains 3 (FHL3) (B). In each panel, histograms represent normalized volume of protein spot (n = 6), and Western blot quantification (n = 7) for adult and old post-menopausal women. Results are indicated as means ± SE. *: P <0.05 indicates significant difference between adult and old women.
