POLR1G and lung cancer: CD3EAP may probably be related to cell proliferation involving in the RNA polymerase I transcription complex.18, 44 In another previous study, we confirmed that co‐expression patterns were consisted in overlapping genes as ERCC1, CD3EAP, and PPP1R13L. Particularly, there was a significant association between CD3EAP exon 3 and ERCC1 exon 11, while CD3EAP exon 1 and PPP1R13L exon 1.45 The potential influence of CD3EAP expression was in response to the regulation of genetic networks known to be associated with DRC and lung cancer risk.
