The lncRNAs DLEU1 and DLEU2 at 13q14.3 are often deleted in multiple types of cancers, and DLEU1 and DLEU2 modulate nuclear factor B function by down-regulating the transcription of their neighboring protein-coding KPNA3 and the microRNAs miR-15 and miR-16 [23]. This evidence concerns the gene DLEU1 and cancer.
