The accumulation of unfolded proteins in the lumen of endoplasmic reticulum (ER) causes ER stress and induces the unfolded protein response (UPR). The UPR alleviates stress by inhibiting protein synthesis, and by promoting the expression of molecular chaperones and other factors involved in ER-associated protein degradation (ERAD). Under cellular stress, the ER activates three branches of the UPR: (i) the protein kinase RNA-activated-like ER kinase–eukaryotic translation initiation factor 2 alpha (PERK-eIF2α) pathway, (ii) the inositol-requiring enzyme 1–X-box binding protein 1 (IRE1-XBP1) pathway, and (iii) the activating transcription factor 6 (ATF6) pathway. However, if ER stress is prolonged and severe, the UPR can result in cell death through the activation of apoptotic pathways. Accumulating evidence indicates that the ER stress is involved in the pathogenesis of not only the protein misfolding disorders such as neurodegenerative disease, but also in the cytotoxicity of drugs, environmental pollutants, and industrial chemicals. Thus, the determination of the modulators that activate or inhibit ER stress signaling pathways is an important field of research. The articles in this special issue will address research aspects related to the inducers or modulators of ER stress in the biological, toxicological, and medical fields.

Title: Neuroprotection Strategy in Retinal Degeneration: Suppressing ER Stress-Induced Cell Death via Inhibition of mTOR Signal

Abstract: Retina is specialized sensory organ essential for light detection and visual formation in the human eye. Retinal neurons dysfunction and death cause vision loss in many eye diseases such as retinitis pigmentosa and achromatopsia. Endoplasmic reticulum (ER) stress plays an important role in the development and pathology of retinal degeneration diseases. However, mammalian target of rapamycin (mTOR) kinase, as a signaling node, controls many cellular processes including protein synthesis, translation, energy metabolism, apoptosis, autophagy and ER stress as well. mTOR complex 1 (mTORC1) operates both upstream and downstream of ER stress signals, which can either enhance or suppress ER stress-induced cell death. This review surveys our knowledge about the influence of mTOR signal on ER stress arising from misfolded proteins and genetic mutations in retinal degeneration diseases and highlights potential neuroprotection strategy and therapeutic implications.

Abstract: Unfolded proteins, accumulated in the endoplasmic reticulum (ER), cause ER stress, which contributes to the development of endocrine disorders such as Ins2Akita diabetes, familial neurohypophysial diabetes insipidus, and Wolfram syndrome. Here, we summarize recent findings on monogenic endocrine disorders in which ER stress is involved. In particular, growth hormone deficiency, caused by heterozygous intron 3 splice-site mutations in the GH1 gene, was clarified to be one of the ER stress-related diseases, suggesting that the anterior pituitary gland is one of the organs which are vulnerable to ER stress.
