In order to test that cyclin A1 is also over-expressed in muscle tissue, we performed another Western blot analysis and found it also up-regulated (>4-fold) in FSHD patient (n = 3) vs. age-matched healthy controls (n = 3) (Fig. 6A, 6B). Here, CCNA1 is linked to facioscapulohumeral muscular dystrophy.
