Retraction for Zhang et al., LncRNA LINC01518 induced by GATA3 promotes cell proliferation, migration and invasion via miR-206/PRKACB in neuroblastoma.

Abstract

Neuroblastoma (NBL) exists as the most common solid malignancy which predominantly occurs in children. Long non-coding RNAs (lncRNAs) have been widely confirmed to exert functions in modulating the pathogenesis of diverse diseases. Nevertheless, whether the putative function of long intergenic non-protein coding RNA 1518 (LINC01518) in NBL has not been elucidated yet. In this study, RT-qPCR was used for determining LINC01518 expression and LINC01518 was found to be notably overexpressed in NBL tissues and cell lines compared with normal nerve tissues and cell lines. Functional experiments and mechanism assays were respectively done for the investigation into cell phenotype and for the exploration of correlation among genes. LINC01518 silencing was discovered to repress cell malignant phenotype. We observed that GATA binding protein 3 (GATA3) was an active transcription factor of LINC01518. Besides, LINC01518 functioned as a competing endogenous RNA (ceRNA), which sequestered microRNA-206 (miR-206) to up-regulate protein kinase cAMP-activated catalytic subunit beta (PRKACB). Afterwards, rescue assays validated the oncogenic role of GATA3/LINC01518/miR-206/PRKACB axis in NBL. To be summarized, our research determined that LINC01518 might be used as a putative molecular marker for NBL diagnosis and treatment.
