Effect of TGF-β type II soluble receptor on GFAP mRNA expression stimulated by TGF-β. A, The conditioned medium form AdTβ-ExR suppresses GFAP mRNA expression in the same manner shown in the protein level, whereas the medium from AdLacZ does not (Fig. 2). B, Three independent examinations were made and the results are expressed as a “fold” increase over the control GFAP mRNA expression (mean ± sd; * p < 0.05).
