Chemical cross-linking with 125I-labeled TGF-beta 1 showed an essentially normal TGF-beta receptor profile in EBV-positive and EBV-negative Burkitt's lymphoma cell lines , and these receptors were shown to be functional in transducing signals , as evidenced by the TGF-beta 1 -mediated modulation of junB gene expression .
