Myocardin-related transcription factor (MRTF) overexpression affects cell cycle regulators. a, b p21, p27, phospho-retinoblastoma protein (P-Rb) and retinoblastoma protein (Rb) expression at day 14 of acinar morphogenesis of the indicated MRTF-overexpressing cell lines. Shown are normalized protein content and a representative immunoblot below. Error bars SEM (n = 3): *p < 0.05, **p < 0.01 (Student’s t test). GAPDH glyceraldehyde-3-phosphate dehydrogenase
