PCBP2 and lung cancer: In lung A549 adenocarcinoma cell lines and LUAD, PCBP2 was shown to bind to 5′ poly-C motif of MYMLR, a long non-coding RNA, regulating the transcription of MYC proto-oncogene [31]; however, whether PCBP2 also regulates NT5E expression in lung cancer awaits further investigation.
