MYCNOS and neuroblastoma: Interestingly, the lncRNA RP1-40E16.9 at chromosome 6: 3182817–3195767, also known as LOC100507194 and LINC02525 but will herein be referred to as lncNB1 (lncRNA highly expressed in neuroblastoma 1), was polyadenylated and displayed an expression pattern very similar to N-Myc and MYCNOS (Fig. 1a, b), suggesting that this lncRNA could be involved in MYCN-amplified neuroblastoma tumorigenesis.
