ABSTRACT
<p><b>OBJECTIVE</b>To study the role of insulin-like growth factor II receptor in free silica-induced transdifferentiation of primary rat lung fibroblasts.</p><p><b>METHODS</b>Rat lung fibroblasts and rat alveolar macrophages were cultured. A transdifferentiation model of primary rat lung fibroblasts was induced by free silica. Levels of α-SMA protein, IGF-IIR protein and mRNA were measured by immunocytochemistry, Western blot and RT-PCR, respectively. Lung fibroblasts were treated with Wortmannin.</p><p><b>RESULTS</b>The expression levels of α-SMA and IGF-IIR increased with the increasing free silica concentration and decreased after Wortmannin was used.</p><p><b>CONCLUSION</b>The IGF-IIR plays an important role in free silica-induced transdifferentiation of primary rat lung fibroblasts.</p>
