Carcinogenesis. 2009 Jun;30(6):1041-8. Epub 2009 Mar 27.

Several candidate TSGs, among which methyl-CpG-binding domain protein 1 (MBD1), CpG-binding protein CXXC1, Sma- and Mad-related protein 4 (SMAD4), deleted in colon cancer (DCC) and methyl-CpG-binding domain protein 2 (MBD2) are closely linked on a 4-Mb DNA region on chromosome18q21.

TGFbeta1 prevents abnormal T-cell activation through the modulation of Ca2+-calcineurin signaling in a Caenorhabditis elegans Sma and Drosophila Mad proteins (SMAD) 3 and SMAD4-independent manner; however, in Treg cells, its effects are mediated, at least in part, through SMAD signaling.

19444386 Cao X, Li X, Hu J, Bao Y: Hydrogen peroxide-induced cellular apoptosis is mediated by TGF-beta2 signaling pathway in cultured human lens epithelial cells. Int Ophthalmol. 2009 May 12.

The objective of this study was to investigate the signaling characteristics of transforming growth factor-beta2 (TGF-beta2) and the Smads (Caenorhabditis elegans, Sma; Drosophila mothers against dpp, Mad) signal pathway of cellular apoptosis induced by hydrogen peroxide with human lens epithelial cells (HLECs).
Smad-4 localization was observed by immunocytochemistry.

Western blot and RT-PCR were used to detect the expression of TGF beta1, Smad 4, collagen type I, III and alpha-smooth muscle actin (alpha-SMA) at the 24 h point.
