In addition, to determine the role of N1DARP in the LINC00261-mediated tumor-suppressive signaling pathway, we generated two LINC00261 overexpression cell models with or without the start codon mutant of N1DARP (LINC00261-N1DARPwt and LINC00261-N1DARPmut). This evidence concerns the gene LINC00261 and neoplasm.
