Meanwhile, there was significant G2/M cell cycle arrest, but no changes of apoptosis, in BE(2)‐C (mutant p53) cells with steady transfection of sh‐CNBP (Figure S2F,G), which was consistent with previous findings that inhibition of ribosome biogenesis induces apoptosis or G2/M arrest in wild‐type or mutant p53 NB cells, respectively.11 Here, TP53 is linked to neuroblastoma.
