| Description: | LINC00839 was found as a potential driver of NB progression. LINC00839 expression was higher in NB tumor tissues and cells. Also, LINC00839 expression was positively correlated with MYCN amplification, advanced INSS stages, and worse prognosis. Silencing of LINC00839 suppressed cell proliferation, migration, invasion, and epithelial-mesenchymal transition (EMT) in vitro. Mechanistically, LINC00839 could act as a sponge of miR-454-3p to facilitate the expression of its target NEUROD1. Moreover, miR-454-3p was demonstrated to exert an anti-cancer activity in NB. More importantly, the tumor-suppressive properties mediated by LINC00839 knockdown were significantly counteracted by the inhibition of miR-454-3p or overexpression of NEUROD1. Our study demonstrates that LINC00839 exerts an oncogenic role in NB through sponging miR-454-3p to up-regulate NEUROD1 expression, deepening our comprehension of lncRNA involved in NB and providing access to the possibility of LINC00839 as a therapeutic target for NB. |

| Disease Name: | Neuroblastoma |
| Sample: | neuroblastoma tissues and cell lines |
| Dysfunction Pattern: | Interaction(miR-338-3p/GLUT1 axis) |
| Validated Method: | In Vivo Experiment//Western Blot//Transfection//Wound Healing Assay//CCK8//qRT-PCR//Flow Cytometry//RIP//Luciferase Report Assay//Colony Formation Assay//Transwell Assay |
| Description: | LINC00839 and GLUT1 abundances were increased in neuroblastoma tissues and cell lines. The high expression of LINC00839 and GLUT1 indicated the lower overall survival. LINC00839 interference constrained neuroblastoma cell proliferation, migration, invasion and glycolysis, and facilitated apoptosis. GLUT1 overexpression or miR-338-3p knockdown could mitigate the influence of LINC00839 silence on neuroblastoma cell processes. LINC00839 could regulate GLUT1 expression via miR-338-3p. LINC00839 knockdown reduced neuroblastoma cell growth in xenograft model. |
