Figure 4From: High-level inducible Smad4-reexpression in the cervical cancer cell line C4-II is associated with a gene expression profile that predicts a preferential role of Smad4 in extracellular matrix composition Northern blot analysis of endogenous TGF-β target genes. Clones 18-2, 28-8 and 28-14 were cultured in the absence or presence of doxycycline and treated with TGF-β for the indicated periods of time. Equal loading was controlled by hybridisation with a Gapdh probe.Back to article page
