KDM4B and cancer: By using microarray analysis, we have identified 26 KDM4B‐dependent genes (16 genes were positively regulated by KDM4B, and 10 genes were negatively regulated by KDM4B) commonly shared by SKOV3ip.1, HCT116, and RCC4 cells, indicating a general regulation of KDM4B in different cancer types (Figure 1).
