Meanwhile, knockdown or ectopic expression of PARP1 or E2F1 prevented NB cells from alteration in expression of MZF1, c‐Kit, PRKCG, and RET induced by overexpression or silencing of MZF1‐AS1 (Figure 5E–H; Figure S5D–I, Supporting Information). The gene discussed is KIT; the disease is neuroblastoma.
