Finally, to examine whether PAQR4 is also highly expressed in NSCLC cancerous cells, we analyzed its relative mRNA expression in normal human bronchial epithelium cell line (BEAS-2B) and NSCLC cancerous cell lines (A549, H1299, H1650, H1975, H358, GLC-82 and SPC-A1). The gene discussed is PAQR4; the disease is non-small cell lung carcinoma.
