The unfolded protein response (UPR) is an important pro-survival pathway that is often activated in tumour cells owing to endoplasmic reticulum stress that is caused by both intrinsic and extrinsic factors. Wang and Kaufman discuss the mechanisms of UPR activation in tumour cells, the importance of this pathway to cancer development and targeting strategies for therapeutic intervention.
