NPM1 and neoplasm: For example, Lnc_bc060912 interacts with PARP1 and nucleophosmin 1 in lung carcinoma cells,38 while spliced‐transcript endothelial‐enriched lncRNA (STEEL) facilitates the expression of Kruppel like factor 2 via recruiting PARP1 to its promoter.39 In this study, we found that PARP1 bound to MZF1‐AS1, and tumor promoting functions of MZF1‐AS1 were mediated, at least in part, through interacting with PARP1 in NB cells.
