To further illustrate the expression changes of these genes in human NSCLC tumor tissues compared with non-tumor control tissues, we tested hnRNP A1/A2, SF2/ASF, and IRF-3 expression by immunohistochemical staining of tissue sections from 63 NSCLC tumor tissues and 39 adjacent non-tumor control tissues as well as 26 bronchiectasis tissues. The gene discussed is IRF3; the disease is non-small cell lung carcinoma.
