A perspective on DNA damage-induced potentiation of the pentose phosphate shunt and reductive stress in chemoresistance

Mol Cell Oncol. 2020 Mar 22;7(3):1733383. doi: 10.1080/23723556.2020.1733383. eCollection 2020.


Metabolic rearrangements and genome instability are two hallmarks of cancer. Recent evidence from our laboratory demonstrates that persistent DNA lesions hampering transcription may cause glucose rerouting through the pentose phosphate shunt and reductive stress. Here, we highlight the relevance of these findings for cancer and chemoresistance development.
