ABSTRACT:
Human mammary epithelial cell line MDA-MB-468 that is lacking endogenous Smad4 was infected with either an adenovirus carrying GFP cDNA (control) or Smad4 cDNA (to restore the Smad4 activity in the cells). Cells were treated with TGF-b1 (0.5 ng/ml) or BMP-7 (300 ng/ml) for 2 or 12h. Smad4-independent vs Smad4-dependent response was measured. Also response to both growth factors was compared.

Transforming growth factors beta (TGF-betas) inhibit growth of epithelial cells and induce differentiation changes, such as epithelial-mesenchymal transition (EMT). On the other hand, bone morphogenetic proteins (BMPs) weakly affect epithelial cell growth and do not induce EMT. Smad4 transmits signals from both TGF-beta and BMP pathways. Stimulation of Smad4-deficient epithelial cells with TGF-beta 1 or BMP-7 in the absence or presence of exogenous Smad4, followed by cDNA microarray analysis, re ...[more]
