Whole-cell extracts were obtained for SDS-PAGE electrophoresis as previously described (25 (link)). Primary antibodies used were rabbit anti-SMARCA4 (Abcam, ab110641), H3K27Me3 (Millipore, 07–449), Myc (Abcam, ab32072), mouse anti-EZH2 (BD Bioscience, 612667), vinculin (Sigma, v9264), Actin (Sigma, A5441), Histone H3 (Abcam, ab1791), MAP2 (Millipore, MAB3418), TUBB3 (Santa Cruz, sc-51670), BAD (Santa Cruz, sc-8044), p16 (Ventana, 725–4713) and CDKN1A/p21 (BD Pharmacogen, 556430) and horseradish peroxidase-conjugated anti-mouse and anti-rabbit IgG (Amersham). Chemiluminescence was used for detection (Perkin–Elmer Life Sciences). Actin or vinculin were used as protein loading controls.
