In CRC RNA-seq datasets from the SYSCOL cohort (Fig. 1b), the CRC TCGA collection and 54 CRC cell lines from EGAD0000100072518 (Supplementary Fig. 1e), high levels of LTR66- and POU5F1B-derived RNAs systematically correlated, indicating that they likely corresponded in their majority to LTR66-POU5F1B TcGTs. The gene discussed is POU5F1B; the disease is colorectal carcinoma.
