Described herein is a LIN28-independent role of TUTases in oncogenesis. Provided herein are compositions and methods for treating cancer via inhibition of TUTases. TUTase depletion also sensitizes the cells to disruptions in RNA metabolism and/or protein metabolism. Thus, further provided herein are strategies of combination therapy, combining TUTase inhibitors, agents that disrupt RNA metabolism, and agents that disrupt protein metabolism, to treat cancer.
