AC142119.1 facilitates the proliferation of NB cells in vitro. A, B The expression of AC142119.1 in NB cell lines after overexpression (A) or knockdown (B) of AC142119.1 was assessed by qRT-PCR. C, D Growth curves generated from CCK-8 assays to determine the proliferation of NB cell lines transfected with indicated vectors (C) or GapmeRs (D). E, F Cell cycle progression of NB cell lines were analyzed by flow cytometry after enforced expression (E) or silencing (F) of AC142119.1. *P < 0.05, **P < 0.01, ***P < 0.001, ns, no significance
