[Endoplasmic reticulum quality control system: a potential target for the treatment of intervertebral disc degeneration].
As the largest organelle in eukaryotic cells, the endoplasmic reticulum (ER) plays a crucial role in regulating intracellular protein folding, translation and assembly. Multiple quality control mechanisms in the ER ensure accurate modification of proteins in the ER lumen are accurately modified, thus maintaining calcium homeostasis, oxidative stress, cellular senescence and apoptosis. These mechanisms include ER stress (ERS), ER autophagy (ER-phagy, ERPA) and ER-associated degradation (ERAD). Intervertebral disc degeneration (IDD) is an age-related degenerative disease of the spine. Although the pathogenesis of IDD has not been fully elucidated, emerging evidence suggests that the ER quality control system may be involved in its progression. Previous studies have focused on mitochondrial quality control and its related mechanisms in diseases, with limited systematic summaries on the ER quality control system. In this paper, we comprehensively reviewed the molecular mechanisms of the ER quality control system and investigated its association with IDD. In addition, we summarized the potential therapeutic strategies targeting the ER quality control system to attenuate IDD progression, offering new insights into the pathogenesis and regenerative repair strategies of IDD.
