Fig. 5From: Risk of radiation-induced pneumonitis after helical and static-port tomotherapy in lung cancer patients and experimental ratsTissue expression of TGF-β. a Right lung samples demonstrated higher tissue TGF-β expression compared to the untreated control samples. b Left lung samples revealed upregulated tissue TGF-β expression. Immunohistochemical staining with anti-TGF-β antibody of c normal control and d right lung sample treated with helical tomotherapy with CCRT. * p <0.05; ** p <0.01; NS, not significant; TGF, transforming growth factor; CCRT, concurrent chemoradiotherapy; bars = 200 μmBack to article page
