PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2024; 134:156010. [PMID: 39232284 DOI: 10.1016/j.phymed.2024.156010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/21/2024] [Revised: 08/14/2024] [Accepted: 08/29/2024] [Indexed: 09/06/2024]
Abstract
BACKGROUND The endoplasmic reticulum (ER) stress is a crucial toxic signaling event triggered by chronic exposure to Ultraviolet B radiation (UVB), which significantly exacerbate photodamage responses in the irradiated skin. Therefore, the identification of agents capable of inhibiting ER stress could serve as a promising therapeutic strategy for addressing the unmet clinical needs in the treatment of UVB-induced photodamage. METHODS A UVB-irradiated mouse model was used and topical administration of Panax ginseng extract was carried out for a duration of 9 weeks. Vitamin E was used as a positive control. After 9 weeks of administration, the skin appearance, epidermal hyperplasia, infiltration of inflammatory cells, apoptosis, and collagen content were measured. The keratinocytes were irradiated with 6 mJ/cm2 UVB to establish an in vitro model. The levels of ER stress and apoptosis were investigated both in vivo and in vitro using qRT-PCR, immunoblotting, and immunofluorescence. RESULTS Among the 14 extracts derived from 13 distinct plant species that were screened, Panax ginseng, Prunus mume, and Camellia japonica showed inhibitory effect on UVB-induced ER stress. Notably, Panax ginseng effectively inhibits collagen degradation and apoptosis in both irradiated keratinocytes and Balb/C mice skin. Furthermore, the silencing of VMP1 significantly impeded the cellular protective effect of Panax ginseng extract on UVB-irradiated keratinocytes, indicating that Panax ginseng exerts its protective effects through targeted promotion of VMP1. CONCLUSION Our data suggest that Panax ginseng extract possess a therapeutical effect on UVB radiation-induced photodamage by promoting VMP1-mediated inhibition of ER stress.

ENVIRONMENTAL TOXICOLOGY AND PHARMACOLOGY 2024; 111:104569. [PMID: 39326718 DOI: 10.1016/j.etap.2024.104569] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/23/2024] [Revised: 09/14/2024] [Accepted: 09/23/2024] [Indexed: 09/28/2024]
Abstract
Phthalate-based polymeric plasticizers are widely used for their durability, transparency, and odorless nature, resulting in human exposure through inhalation, ingestion, or contaminated water. Epidemiological studies have identified bis-phthalate as a potential cardiovascular disease risk factor, though its mechanisms remain unclear. This study investigates the effects of bis-phthalate on endothelial dysfunction (ED), an early event in cardiovascular complications, with a focus on Endoplasmic Reticulum (ER) stress pathways. We observed dose- and time-dependent cytotoxicity in endothelial cells exposed to bis-phthalate, accompanied by elevated expression of ER stress markers (GRP78, IRE-1α, CHOP) and oxidative stress markers (TXNIP, P22phox), as measured by qPCR. Reactive oxygen species (ROS) levels also increased dose-dependently, as determined by H2DCFDA using flow cytometry. These findings suggest that bis-phthalate exposure induces both oxidative and ER stress, leading to the development of ED, providing insights into its potential role in cardiovascular disease progression.

Toxicology 2024; 509:153954. [PMID: 39299507 DOI: 10.1016/j.tox.2024.153954] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2024] [Revised: 09/06/2024] [Accepted: 09/14/2024] [Indexed: 09/22/2024]
Abstract
Psoralen is a main active molecule of the traditional Chinese herb medicine Fructus Psoraleae. Our previous studies have shown that psoralen induced liver injury through the endoplasmic reticulum stress (ERS) signaling pathways. In this article, we studied whether the ERS inhibitor, 4-phenylbutyrate acid (4-PBA) could inhibit the liver toxicity caused by psoralen, and explored the underlying mechanisms. Mice were given the solvent, 20mg/kg, 40mg/kg, 80mg/kg of psoralen, or 80mg/kg of psoralen plus 4-PBA for 14 days. We found that 4-PBA significantly reduced the serum LDH and liver tissue MDA level, increased the activities of SOD and CAT, reduced liver weight and coefficient, repaired histopathological damage, and inhibited hepatocytes apoptosis induced by psoralen. RNA-seq transcriptomics found that except for the endoplasmic reticulum, the mitochondria was severely affected by psoralen. And genes involved in mitochondrial fusion, apoptosis, protein folding, and autophagy were found differently expressed in the psoralen group. Further studies found that 4-PBA inhibited the overexpression of GRP78 and CHOP, increased the Bcl-2/Bax ratio, and reduced the expression of Caspase-3. Moreover, 4-PBA reduced the overexpression of mitochondrial fission protein DRP1, increased the expression of fusion proteins Mfn-2 and OPA1, but has no inhibitory effects on autophagy proteins Atg5 or LC3A/B. In conclusion, 4-PBA inhibited ERS and reestablished mitochondrial fusion-fission balance, thereby blocking cell apoptosis, oxidative stress, and mitochondrial dysfunction, thus prevented against psoralen-induced hepatotoxicity.

Mokrzyński K, Szewczyk G. Photoreactivity of polycyclic aromatic hydrocarbons (PAHs) and their mechanisms of phototoxicity against human immortalized keratinocytes (HaCaT). THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 924:171449. [PMID: 38460699 DOI: 10.1016/j.scitotenv.2024.171449] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Revised: 03/01/2024] [Accepted: 03/01/2024] [Indexed: 03/11/2024]
Abstract
Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous organic compounds in the environment. They are produced by many anthropogenic sources of different origins and are known for their toxicity, carcinogenicity, and mutagenicity. Sixteen PAHs have been identified as Priority Pollutants by the US EPA, which are often associated with particulate matter, facilitating their dispersion through air and water. When human skin is exposed to PAHs, it might occur simultaneously with solar radiation, potentially leading to phototoxic effects. Phototoxic mechanisms involve the generation of singlet oxygen and reactive oxygen species, DNA damage under specific light wavelengths, and the formation of charge transfer complexes. Despite predictions of phototoxic properties for some PAHs, there remains a paucity of experimental data. This study examined the photoreactive and phototoxic properties of the 16 PAHs enlisted in the Priority Pollutants list. Examined PAHs efficiently photogenerated singlet oxygen and superoxide anion in simple solutions. Furthermore, singlet oxygen phosphorescence was detected in PAH-loaded HaCaT cells. Phototoxicity against human keratinocytes was evaluated using various assays. At 5 nM concentration, examined PAHs significantly reduced viability and mitochondrial membrane potential of HaCaT cells following the exposure to solar simulated light. Analyzed compounds induced a substantial peroxidation of cellular proteins after light treatment. The results revealed that a majority of the examined PAHs exhibited substantial reactive oxygen species photoproduction under UVA and violet-blue light, with their phototoxicity corresponding to their photoreactive properties. These findings improve our comprehension of the interactions between PAHs and human skin cells under environmental conditions, particularly when exposed to solar radiation.

Abstract
BACKGROUND The unfolded protein response (UPR) is one of the cytoprotective mechanisms against various stresses and essential for the normal function of skin. Skin injury caused by ionizing radiation (IR) is a common side effect of radiotherapy and it is unclear how UPR affects IR-induced skin injury. OBJECTIVES To verify the effect of UPR on IR-induced DNA damage in keratinocytes and the relation between an endoplasmic reticulum (ER) protein KTN1 and UPR. METHODS All experiments were performed on keratinocytes models: HaCaT and HEK-A. ER lumen and the expression levels of KTN1 and UPR pathway proteins (PERK, IRE1α and ATF6) were examined by transmission electron microscopy and immunoblotting, respectively. 4-PBA, an UPR inhibitor, was used to detected its effects on DNA damage and cell proliferation. Subsequently, the effects of KTN1 deletion on UPR, DNA damage and cell proliferation after IR were detected. Tunicamycin was used to reactivate UPR and then we examined its effects on DNA damage. RESULTS UPR was activated by IR in keratinocytes. Inhibition of UPR aggravated DNA damage and suppressed cell proliferation after IR. KTN1 expression was upregulated by IR and KTN1 depletion reduced ER expansion and the expression of UPR-related proteins. Moreover, KTN1 depletion aggravated DNA damage and suppressed cell proliferation after IR could reversed by reactivation of UPR. CONCLUSION KTN1 deletion aggravates IR-induced keratinocyte DNA damage via inhibiting UPR. Our findings provide new insights into the mechanisms of keratinocytes in response to IR-induced damage.

Abstract
Aging is a normal and complex biological process. Skin is located in the most superficial layer of the body, and its degree of aging directly reflects the aging level of the body. Endoplasmic reticulum stress refers to the aggregation of unfolded or misfolded proteins in the endoplasmic reticulum and the disruption of the calcium ion balance when cells are stimulated by external stimuli. Mild endoplasmic reticulum stress can cause a series of protective mechanisms, including the unfolded protein response, while sustained high intensity stimulation leads to endoplasmic reticulum stress and eventually apoptosis. Photoaging caused by ultraviolet radiation is an important stimulus in skin aging. Many studies have focused on oxidative stress, but increasing evidence shows that endoplasmic reticulum stress plays an important role in photoaging. This paper reviews the development and mechanism of endoplasmic reticulum stress (ERS) in skin photoaging, and provides research directions for targeting the ERS pathway to slow aging.

Abstract
Epithelial skin cancers are extremely common, but the mechanisms underlying their malignant progression are still poorly defined. Here, we identify the NRF3 transcription factor as a tumor suppressor in the skin. NRF3 protein expression is strongly downregulated or even absent in invasively growing cancer cells of patients with basal and squamous cell carcinomas (BCC and SCC). NRF3 deficiency promoted malignant conversion of chemically induced skin tumors in immunocompetent mice, clonogenic growth and migration of human SCC cells, their invasiveness in 3D cultures, and xenograft tumor formation. Mechanistically, the tumor-suppressive effect of NRF3 involves HSPA5, a key regulator of the unfolded protein response, which we identified as a potential NRF3 interactor. HSPA5 levels increased in the absence of NRF3, thereby promoting cancer cell survival and migration. Pharmacological inhibition or knock-down of HSPA5 rescued the malignant features of NRF3-deficient SCC cells in vitro and in preclinical mouse models. Together with the strong expression of HSPA5 in NRF3-deficient cancer cells of SCC patients, these results suggest HSPA5 inhibition as a treatment strategy for these malignancies in stratified cancer patients.

Abstract
The diabetes mellitus (DM) skin shows skin barrier dysfunction and skin lipid abnormality, similar to conditions induced by systemic or local glucocorticoid excess and aged skin. Inactive glucocorticoid (GC) is converted into active glucocorticoid by 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1). Hyperglycemia in DM and excessive GC are known to increase endoplasmic reticulum (ER) stress. We hypothesized that hyperglycemia affects systemic GC homeostasis and that the action of skin 11β-HSD1 and GC contributes to increased ER stress and barrier defects in DM. We compared 11β-HSD1, active GC, and ER stress between hyperglycemic and normoglycemic conditions in normal human keratinocytes and db/db mice. 11β-HSD1 and cortisol increased with time in keratinocyte culture under hyperglycemic conditions. 11β-HSD1 siRNA-transfected cells did not induce cortisol elevation in hyperglycemic condition. The production of 11β-HSD1 and cortisol was suppressed in cell culture treated with an ER stress-inhibitor. The 14-week-old db/db mice showed higher stratum corneum (SC) corticosterone, and skin 11β-HSD1 levels than 8-week-old db/db mice. Topical 11β-HSD1 inhibitor application in db/db mice decreased SC corticosterone levels and improved skin barrier function. Hyperglycemia in DM may affect systemic GC homeostasis, activate skin 11β-HSD1, and induce local GC excess, which increases ER stress and adversely affects skin barrier function.

Abstract
Inflammatory bowel disease (IBD) is a chronic inflammatory disease involving the digestive tract, characterized by abdominal pain, diarrhea, rectal bleeding, and so on, which can make patients physically weakened and live difficultly. Although IBD has been recognized for many years, the pathogenesis of IBD has not yet been established and damage to intestinal barrier is thought to be closely associated with IBD. Intestinal barrier is an innate barrier that maintains the homeostasis of the intestinal environment and impedes pathogenic bacteria and toxins, and the endoplasmic reticulum (ER) has recently been found to be involved in maintaining the integrity of intestinal barrier. Endoplasmic reticulum stress (ERS) is a status of endoplasmic reticulum damaged when unfolded or misfolded proteins accumulate in excess of the degradation systematic clearance limit of the misfolded proteins. The regulation of ERS on protein folding synthesis and maintenance of cellular homeostasis is an important factor in influencing the integrity of the intestinal barrier. This paper mainly discusses the relationship between ERS and the intestinal barrier, aiming to understand the regulatory role of ERS on the intestinal barrier and the mechanism and to improve new solutions and notions for the treatment or prevention of IBD.

Xinfuli Granule (XG) was constructed on the basis of classical formula "Baoyuan decoction" to enhance the function of nourishing Qi, activating blood and removing water retention. XG treatment has obtained clinical effect on HF patients. AIM OF THE STUDY The regulation of XG on energy metabolism of HF was investigated with special focus on endoplasmic reticulum stress (ERS) and mitochondrial function. MATERIALS AND METHODS Components of XG was acquired by UPLC/Q-TOF-MS Analysis, left anterior descending ligation(LAD)-induced HF rats model and hypoxia-ischemia(H-I)-induced H9c2 cells model were constructed to evaluate the effect of XG treatment. Cardiac function was evaluated by echocardiographic parameters, energy metabolism was evaluated by metabolites and ATP/ADP/AMP levels in blood samples, cardiomyocyte morphology and myocardial fibrosis were assessed by HE staining and Masson staining, mitochondrial ultrastructure was observed under Transmission Electron Microscope, viability and apoptosis rate of H9c2 cells was detected by cell counting kit-8 reaction and flow cytometry analysis, respectively. Mitochondrial membrane potential (MMP) of H9c2 cells was observed by JC-1 kit under fluorescent microscope, expression of peroxisome-proliferator-activated receptor (PPAR)-coactivator (PGC1α), ERS-related genes and RHOA/ROCK pathway were analysed by Quantitative Real-time PCR (RT-qPCR) and Western Blot. RESULTS Here, we showed that XG alleviated cardiac metabolic remodeling and stimulated ATP production through elevated expression of PGC1α in HF rats. XG also helped recover mitochondrial deformation and decrease apoptosis rate accompanied by an increase of the Bcl2/Bax ratio and the mitochondrial membrane potential in hypoxia-ischemia (H-I) H9c2 cells. In addition, we found that XG downregulated ERS-related proteins ATF4, CHOP, Phospho-eIF2α, and Phospho-PERK, and suppressed the RHOA/ROCK pathway, which served as a potential mediator of ERS. CONCLUSIONS we found that XG improved energy production by alleviating mitochondrial injury and inhibiting ERS in heart failures mediated by the RHOA/ROCK pathway.

Abstract
Applying natural mineral water to skin care is a popular tendency and many cosmetics products based on thermal spring water have been developed. The special location and environmental conditions provide Dead Sea water (DSW) with unique ion composition and concentrations, which bring comprehensive positive effects on skin health. This article reviews two potential action modes of DSW, and the biological function of DSW and its related complex in dermatology and skin care. Previous studies have proved the functions of skin moisturization, anti-inflammation, skin barrier repair, and anti-pollution. Especially, the anti-aging effect of DSW and related complexes can act in three different ways: keratinocyte rejuvenation, photo-protection, and cellular energy elevation. Additionally, the issues that need further investigation are also discussed. We hope that this review will help to improve the understanding of DSW and its related complex, and further contribute to product development in the skincare industry.

Abstract
The endoplasmic reticulum (ER) plays an important role in the regulation of protein synthesis. Alterations in the folding capacity of the ER induce stress, which activates three ER sensors that mediate the unfolded protein response (UPR). Components of the pathways regulated by these sensors have been shown to regulate autophagy. The last corresponds to a mechanism of self-eating and recycling important for proper cell maintenance. Ultraviolet radiation (UV) is an external damaging stimulus that is known for inducing oxidative stress, and DNA, lipid and protein damage. Many controversies exist regarding the role of UV-inducing ER stress or autophagy. However, a connection between the three of them has not been addressed. In this review, we will discuss the contradictory theories regarding the relationships between UV radiation with the induction of ER stress and autophagy, as well as hypothetic connections between UV, ER stress and autophagy.

J Food Biochem 2022; 46:e14221. [PMID: 35596593 DOI: 10.1111/jfbc.14221] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2022] [Revised: 03/07/2022] [Accepted: 04/04/2022] [Indexed: 12/29/2022]
Abstract
Human oral squamous cell carcinoma (OSCC) has been one of the most common oral cancers owing to high percentage of betel nuts chewers, smokers, and alcohol consumption. With current treatment strategies in OSCC, more than half patients relapse and develop distant metastases with poor prognosis. To overcome the incident, OSCC poses a challenge in current therapies and treatments. Naringenin, a natural flavonoid, has been noted for antitumor effects on various types of cancers; however, the effects of naringenin on OSCC remain bias. In this study, naringenin demonstrated the potential multifunction in human OSCC cells not only leading to cell apoptosis, but also alternating the general function of autophagy, serving as pro-survival mechanism by inducing the endoplasmic reticulum (ER) stress signaling through intracellular reactive oxygen species (ROS) production. In the process of programmed cell death, naringenin induced apoptotic signaling through caspase-cascade, mitochondrial dysfunction, and ER stress by aberrance of Ca2+ release. In contrast, under the presence of naringenin, the pro-survival has been altered into pro-death to activate the caspases-mediated apoptosis achieving cell death. The cross-function of apoptosis and autophagy has demonstrated the effect of naringenin-induced intracellular ROS activity in OSCC cells. Therefore, this study found that the effect of naringenin induces intracellular ROS to trigger programmed cell death and ER stress through the mechanisms of apoptosis and autophagy in human oral squamous carcinoma. PRACTICAL APPLICATIONS: This study revealed that naringenin debilitated the OSCC cell viability via the intracellular ROS production, ER stress, and autophagy, leading to cell apoptosis. Based on these studies and findings, naringenin provided an antitumor effect as a novel natural compound to improve the current therapies in OSCC.

Combined Toxicological Effects of Di (2-Ethylhexyl) Phthalate and UV-B Irradiation through Endoplasmic Reticulum Stress-Tight Junction Disruption in Human HaCaT Keratinocytes. Int J Mol Sci 2022; 23:ijms23147860. [PMID: 35887207 PMCID: PMC9318540 DOI: 10.3390/ijms23147860] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2022] [Revised: 07/13/2022] [Accepted: 07/16/2022] [Indexed: 11/16/2022] Open
Abstract
Di (2-ethylhexyl) phthalate (DEHP) is widely used as a plasticizer, and human exposure to DEHP is widespread and frequent. However, information about the combined effect of DEHP and ultraviolet (UV)-B on the skin are still limited. We investigated the cytotoxic effects of DEHP and UV-B on HaCaT keratinocytes and evaluated the related underlying mechanisms involving endoplasmic reticulum (ER) stress signals and the disruption of junction complexes as an effective target for skin inflammation. Our results revealed that co-treatment with DEHP and UV-B irradiation alleviated the cell cytotoxicity and markedly decreased X-box binding protein 1 (XBP1), endoplasmic reticulum oxidoreductase 1 alpha (Ero1α), and C/EBP homologous protein (CHOP) whereas a single dose of 40 mJ/cm2 UV-B generated mild ER stress to slightly less or similar levels as that seen with DEHP. DEHP was also shown to inhibit tight junctions (TJs) after UV-B irradiation, increased apoptosis by altering apoptotic gene Bax and stress kinases, JNK, and p38 MAPK. Furthermore, exposure of HaCaT cells to DEHP and UV-B irradiation resulted in the marked suppression of the nuclear factor kappa B (NF-κB)/p65 signaling pathway. Taken together, our data suggest that nontoxic DEHP and UV-B irradiation regulated ER stress and epidermal TJ disruption with the induction of apoptosis activation and the secretion of proinflammatory cytokines such as interleukin 1 beta (IL-1β) and IL-6 in human keratinocytes. Further investigation is needed to confirm the mechanisms implicated in its toxicity and determine the effects of exposure to DEHP and UV-B irradiation on markers involved in this study.

Abstract
Blood-testis barrier (BTB) damage promotes spermatogenesis dysfunction, which is a critical cause of male infertility. Dyslipidemia has been correlated with male infertility, but the major hazardous lipid and the underlying mechanism remains unclear. In this study, we firstly discovered an elevation of palmitic acid (PA) and a decrease of inhibin B in patients with severe dyszoospermia, which leaded us to explore the effects of PA on Sertoli cells. We observed a damage of BTB by PA. PA penetration to endoplasmic reticulum (ER) and its damage to ER structures were exhibited by microimaging and dynamic observation, and consequent ER stress was proved to mediate PA-induced Sertoli cell barrier disruption. Remarkably, we demonstrated a critical role of aberrant protein palmitoylation in PA-induced Sertoli cell barrier dysfunction. An ER protein, Calnexin, was screened out and was demonstrated to participate in this process, and suppression of its palmitoylation showed an ameliorating effect. We also found that ω-3 poly-unsaturated fatty acids down-regulated Calnexin palmitoylation, and alleviated BTB dysfunction. Our results indicate that dysregulated palmitoylation induced by PA plays a pivotal role in BTB disruption and subsequent spermatogenesis dysfunction, suggesting that protein palmitoylation might be therapeutically targetable in male infertility. An elevation of circulating PA was identified in patients with severe dyszoospermia. PA-induced over-palmitoylation in Sertoli cells leads to ER stress and BTB damage. The palmitoylation of the ER protein Calnexin regulates Sertoli cell barrier function. ω-3 PUFAs ameliorate PA-induced damage and over-palmitoylation in Sertoli cells.

Abstract
Darier’s disease (DD) is a rare autosomal dominant genodermatosis caused by mutations in the ATP2A2 gene, which encodes for the sarcoendoplasmic reticulum calcium ATPase type 2 isoform (SERCA2). In epidermal keratinocytes, the decrease in SERCA2 inhibits the transportation of desmosomal proteins to the plasma membrane, resulting in acantholysis and dyskeratosis. We present the first case of DD with a novel missense mutation in the ATP2A2 gene and successfully treated with calcipotriol/betamethasone dipropionate two-compound ointment. A 34-year-old Japanese woman presented with erythema and scales on the scalp and clusters of keratotic papules on the neck and groin. Similar symptoms were observed in her father, younger sister, and daughter. Histopathological examination revealed corps ronds in the granular layer and grains in the horny layer of the epidermis and acantholytic lacuna just above the basal layer. She was diagnosed with DD. A novel heterozygous missense mutation, c.616A>C (p.Asn206His), was detected in the ATP2A2 gene in both the patient and her daughter. The patient was treated with calcipotriol/betamethasone dipropionate two-compound ointment, which resulted in improvement of the skin eruption. This two-compound topical ointment may be a promising therapeutic strategy in the treatment for DD.

Abstract
The unfolded protein response is activated by UVB irradiation, but the role of a key mediator, IRE1α, is not clear. In this study, we show that mice with an epidermal IRE1α deletion are sensitized to UV with increased apoptosis, rapid loss of UV-induced cyclopyrimidine dimer‒positive keratinocytes, and sloughing of the epidermis. In vitro, Ire1α-deficient keratinocytes have increased UVB sensitivity, reduced cyclopyrimidine dimer repair, and reduced accumulation of γH2AX and phosphorylated ATR, suggesting defective activation of nucleotide excision repair. Knockdown of XBP1 or pharmacologic inhibition of the IRE1α ribonuclease did not phenocopy Ire1α deficiency. The altered UV response was linked to elevated intracellular calcium levels and ROS, and this was due to dysregulation of the endoplasmic reticulum calcium channel InsP3R. Pharmacologic, genetic, and biochemical studies linked the regulation of the Ins3PR, intracellular calcium, and normal UV DNA damage response to CIB1 and the IRE1α‒TRAF2‒ASK1 complex. These results suggest a model where IRE1α activation state drives CIB1 binding either to the InsP3R or ASK1 to regulate endoplasmic reticulum calcium efflux, ROS, and DNA repair responses after UV irradiation.

Abstract
The endoplasmic reticulum (ER) hosts linear polypeptides and fosters natural folding of proteins through ER-residing chaperones and enzymes. Failure of the ER to align and compose proper protein architecture leads to accumulation of misfolded/unfolded proteins in the ER lumen, which disturbs ER homeostasis to provoke ER stress. Presence of ER stress initiates the cytoprotective unfolded protein response (UPR) to restore ER homeostasis or instigates a rather maladaptive UPR to promote cell death. Although a wide array of cellular processes such as persistent autophagy, dysregulated mitophagy, and secretion of proinflammatory cytokines may contribute to the onset and progression of cardiometabolic diseases, it is well perceived that ER stress also evokes the onset and development of cardiometabolic diseases, particularly cardiovascular diseases (CVDs), diabetes mellitus, obesity, and chronic kidney disease (CKD). Meanwhile, these pathological conditions further aggravate ER stress, creating a rather vicious cycle. Here in this review, we aimed at summarizing and updating the available information on ER stress in CVDs, diabetes mellitus, obesity, and CKD, hoping to offer novel insights for the management of these cardiometabolic comorbidities through regulation of ER stress.

Abstract
Darier's disease (DD) and Hailey-Hailey disease (HHD), belonging to a hereditary acantholytic dermatosis caused by mutations in ATP2A2 and ATP2C1, respectively, are easily affected by eczema herpeticum (EH) induced by mostly herpes simplex virus (HSV) superinfection. However, the mechanisms by which those patients with DD or HHD are susceptible to HSV are not well elucidated. Here, we experienced two cases with DD, including three episodes of the exacerbation of DD after the development of severe EH. We serially measured serum cytokines before and after the development of EH and DD in these patients. Furthermore, we analyzed the effect of pro-inflammatory cytokines on the mRNA expression of ATP2A2 and ATP2C1, and HSV growth. The timing of EH onset in these patients was coincident with the increase in serum interleukin (IL)-6 and tumor necrosis factor (TNF)-α levels. Moreover, the exacerbation of DD occurred in the non-lesional skin of EH after EH remission (mean 24 days, ranging 15-30 days after EH onset). IL-6 and TNF-α enhanced HSV-1 growth, and ATP2A2 and ATP2C1 mRNA levels were downregulated by IL-6 stimulation in cultured differentiated keratinocytes. Increased pro-inflammatory cytokines IL-6 and TNF-α lead to development of severe EH lesions via accentuation of HSV growth. IL-6 acts as an exacerbating factor of DD and HHD by downregulating the expression of responsible genes.
