To validate the effect of rs9606 on APA, we performed qualitative 3′Rapid Amplification of cDNA Ends (3′RACE) and quantitative polymerase chain reaction (qPCR) analyses of changes of LYRM4 3′UTR length in NSCLC cell lines (Figure 3E). The gene discussed is LYRM4; the disease is non-small cell lung carcinoma.
