KMT5A and neuroblastoma: Of note, differently from neuroblastoma but in accordance to what was observed in myeloma [10, 11], we have here demonstrated that DNA damage, induced by SETD8 inhibition, arrests glioblastoma cell cycle progression regardless of p53 proficiency: p53-proficient cells arrest at G1/S; p53-deficient cells arrest at G2/M checkpoint.
