Transforming growth factor (TGF) beta(2) gene expression was examined
in murine, rat and human lung by in situ hybridization with riboprobes
. Hybridization signal was observed in a variety of cells with the sen
se probe, and Northern-blot analysis with this probe demonstrated the
presence of a novel 3.5 kb transcript. This first report suggesting th
e existance of a natural TGF beta(2) antisense transcript raises the p
ossibility that such a transcript may play a role in regulating TGF be
ta(2) production.
