Elevated cAMP levels inhibit DUX4 target gene expression. a–d Expression of the DUX4 target gene MBD3L2 in MB200 FSHD2 myoblasts (a, c) or myotubes (b, d) treated with the adenylyl cyclase activators NKH 477 or forskolin (a–b) or the cAMP analog dbcAMP (c–d) at the indicated concentrations. Data are normalized to untreated controls
