Western blot and quantitative RT-PCR analyses revealed that both the protein and mRNA levels of URGCP were markedly higher in all 7 NSCLC cell lines, namely, NCI-H292, NCI-H596, NCI-H1650, SK-MES-1, A549, NCI-H1975 and 95D, compared to those in primary normal lung epithelial cells (NLEC) (Fig. 1A and 1B). Here, URGCP is linked to non-small cell lung carcinoma.
