Ex vivo experiments in nasopharyngeal carcinoma showed that the ILF2/ILF3 complex interacts with differentiation antagonizing non-protein coding RNA (DANCR) to stabilize the hypoxia-inducible factor 1 subunit alpha (HIF1A) mRNA, enhancing cell migration and invasion (34). This evidence concerns the gene HIF1A and nasopharyngeal carcinoma.
