MKI67 and neuroblastoma: We found that the proportion of ki67-positive cells (ki67% = 13.84 ± 2.412; n = 59) in the low-expression FUBP1 group (H-Score < 5) was significantly lower than that in the high-expression FUBP1 group (H-Score ≥ 5; ki67% = 23.84 ± 3.86; n = 31; Fig. 1i) in all NB tissues, suggesting that FUBP1 may play an important role in the development of NB independent of N-Myc.
