As ER stress ensues, the unfolded protein response (UPR), comprising three signaling pathways—inositol-requiring enzyme 1, protein kinase R-like endoplasmic reticulum kinase, and activating transcription factor 6 promptly activates to enhance the ER’s protein-folding capacity and restore ER homeostasis. However, prolonged ER stress levels propels the UPR towards cellular demise and the subsequent inflammatory cascade, contributing to the development of human diseases, including cancer, neurodegenerative disorders, and diabetes. Notably, increased expression of all three UPR signaling pathways has been observed in these pathologies, and reduction in signaling molecule expression correlates with decreased proliferation of disease-associated target cells. Consequently, therapeutic strategies targeting ER stress-related interventions have attracted significant research interest. In this review, we elucidate the critical role of ER stress in cancer, metabolic, and neurodegenerative diseases, offering novel therapeutic approaches for these conditions.  \nKeywords Endoplasmic reticulum stress, Signaling pathway, Cancer, Neurodegenerative diseases, Metabolic, Therapeutic strategies  \nIntroduction  \nProteins are essential cellular components critical for maintaining and regulating biological functions. Deviations in protein expression, folding, function, or localization can significantly affect the biological functions of organisms(Jayaraj et al. 2020). The ER is the primary site for protein and lipid synthesis and calcium ion storage  \n†Siqi Yuan, Dan She and Shangming Jiang contributed equally to this work.  \n*Correspondence: Ling Ma[malingxh@163.com](malingxh@163.com)  \n1Department of Clinical Laboratory, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, 430022 Wuhan, China  \nin eukaryotic cells, playing a vital role in regulating protein secretion and synthesis. Under normal conditions, only correctly folded proteins are secreted, while genetic mutations or stress conditions, such as hypoxia and oxidative stress, lead to the formation of misfolded proteins. The accumulation of misfolded proteins induces ER stress and triggers the UPR, which relieves ER stress by enhancing the ER’s protein folding capacity and degrading misfolded proteins. Persistent ER stress ultimately leads to cell death(Walter and Ron 2011).  \nMaintaining protein homeostasis is essential for the normal physiological activities of organisms. Chronic ER stress is increasingly recognized as a key factor in a growing number of human diseases(Dikic 2017). Research confirms that ER stress is activated in many human  \n© The Author(s) 2024.
