Long noncoding RNAs ( LncRNAs) have emerged as new candidates in the field of cancer research and may have potential roles in both oncogenic and tumor suppressive pathways.Therefore,the characterization of the functions and clinical applicability of IncRNAs has great biological and clinical importance.A novel large intergenic noncoding RNA ( lincRNA ) named ncRAN, which was originally indentified in advanced neuroblastomas,is known to have 2 isoforms (long-form and short-form).
