The role of the ZRANB3/RNR signaling axis in cancer comes into focus

Our new paper detailing how ZRANB3 is a poignant example of non-oncogene addiction in H-RasG12V-induced transformation and how nuclear RNR-alpha can inhibit this function is set to appear in Cell Chemical Biology. Critically, some approved anti-cancer drugs targeting RNR-alpha such as clofarabine also taps into this pathway:

Clofarabine commandeers the RNR-α—ZRANB3 nuclear signaling axis
