Cover Story: The unfolded protein response (UPR) is an adaptive response triggered by the endoplasmic reticulum stress due to altered cell protein homeostasis. The UPR can be activated by three main mediators: PERK, ATF6α, and IRE1α. Proteostasis is frequently deregulated in cancer, and the UPR is emerging as a crucial signaling network in controlling the survival of several neoplasias, including acute leukemias. The activation of the ATF6 pathway in AML cells upregulates the calreticulin that suppresses the translation of C/EBPα, contributing to the block in myeloid differentiation. XBP1, IRE1α, and GRP78 are upregulated in B-ALL patients, leading to UPR-induced apoptosis resistance, while c-Myc regulates the UPR response in T-ALL cells via increased PERK activation (prosurvival signaling). Therefore, targeting UPR-driven prosurvival pathways could represent a novel therapeutic strategy in acute leukemias. View this paper
