Levels of Activin mRNA and protein in the mouse lung. A. Inhba and Inhbb expression levels in asbestos (Asb)- and silica-exposed mice at 30 days after oropharyngeal aspiration. The expression levels are shown relative to the expression levels of Inhba in control-1. Control (Ctrl) animals are non-treated and non-exposed mice. B. Immunoblotting analyses of lung tissue lysates using anti-inhibin ßB specific antibodies. The mobility of recombinant 25 kDa human activin-B (C, control) is shown on the right. Ponceau staining indicates equal loading. C. Quantification of inhibin ßB band intensities.
