MCM2 and neuroblastoma: Although, most likely due to the small number of animal treated, the Log Rank test performed on Kaplan Meier data yielded statistically significant differences only between the co-administration of cisplatin and ciprofloxacin if compared to ciprofloxacin alone control group (Log rank test, p < 0.05), the average lifespan of 24.4 days of cisplatin/ciprofloxacin-treated mice compared to that of 13 days shown by the only cisplatin-treated group is encouraging and again keeps in line with a key role of MCM2 played in NB aggressiveness (Figure 6E,F).
