Core Tip

Core Tip: Monopolar spindle-binding protein 3B (MOB3B) functions as a signal transducer and altered MOB3B expression is associated with the development of human cancers. In this study, we investigated the effects of MOB3B in colorectal cancer (CRC). We found that loss of MOB3B expression promoted CRC development and malignant behaviors, suggesting a potential tumor suppressive role of MOB3B in CRC by inhibition of mechanistic target of rapamycin kinase/autophagy signaling.
