HERPUD1 mediates palmitic acid-induced UPR sustaining TNBC aggressiveness and is destabilized by CK2 pharmacological inhibition
HERPUD1 is identified as a critical mediator of palmitic acid-induced unfolded protein response (UPR) in triple-negative breast cancer (TNBC), promoting tumor aggressiveness. The study demonstrates that HERPUD1 silencing enhances sensitivity to doxorubicin, suggesting its potential as a therapeutic target. Additionally, CK2-mediated phosphorylation is highlighted as a key regulatory mechanism for HERPUD1 stability, linking it to obesity-related tumor progression and indicating the need for novel therapeutic strategies in TNBC.
