POU2F3 and small cell lung carcinoma: We obtained publicly available chromatin immunoprecipitation sequencing (ChIPseq) data for POU2AF2, POU2AF3 and POU2F3, along with activating transcription markers across SCLC-P cell lines (NCIH211, NCIH526 and NCIH1048), as CRC cell lines lack strong expression of 11q23.1 genes.9
