To determine whether the differential expression of URGCP has clinical significance for NSCLC patients, URGCP expression was examined by IHC in 212 archival paraffin-embedded, human NSCLC specimens, including 83 cases, 46 cases, 66 cases and 17 cases of stage I, II, III and IV, respectively (Supplementary Table 1). This evidence concerns the gene URGCP and non-small cell lung carcinoma.
