Interaction of Bmal1 and eIF2α/ATF4 pathway was involved in Shuxie compound alleviation of circadian rhythm disturbance-induced hepatic endoplasmic reticulum stress. JOURNAL OF ETHNOPHARMACOLOGY 2023; 312:116446. [PMID: 37019162 DOI: 10.1016/j.jep.2023.116446] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Revised: 03/28/2023] [Accepted: 03/29/2023] [Indexed: 05/08/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Shuxie Compound (SX) combines the composition and efficacy of Suanzaoren decoction and Huanglian Wendan decoction. It can soothe the liver, regulate the qi, nourish the blood and calm the mind. It is used in the clinical treatment of sleep disorder with liver stagnation. Modern studies have proved that circadian rhythm disorder (CRD) can cause sleep deprivation and liver damage, which can be effectively ameliorated by traditional Chinese medicine to soothe the liver stagnation. However, the mechanism of SX is unclear. AIM OF THE STUDY This study was designed to demonstrate the impact of SX on CRD in vivo, and confirm the molecular mechanisms of SX in vitro. MATERIALS AND METHODS The quality of SX and drug-containing serum was controlled by UPLC-Q-TOF/MS, which were used in vivo and in vitro experiments, respectively. In vivo, a light deprivation mouse model was used. In vitro, a stable knockdown Bmal1 cell line was used to explore SX mechanism. RESULTS Low-dose SX (SXL) could restore (1) circadian activity pattern, (2) 24-h basal metabolic pattern, (3) liver injury, and (4) Endoplasmic reticulum (ER) stress in CRD mice. CRD decreased the liver Bmal1 protein at ZT15, which was reversed by SXL treatment. Besides, SXL decreased the mRNA expression of Grp78/ATF4/Chop and the protein expression of ATF4/Chop at ZT11. In vitro experiments, SX reduced the protein expression of thapsigargin (tg)-induced p-eIF2α/ATF4 pathway and increase the viability of AML12 cells by increasing the expression of Bmal1 protein. CONCLUSIONS SXL relieved CRD-induced ER stress and improve cell viability by up-regulating the expression of Bmal1 protein in the liver and then inhibiting the protein expression of p-eIF2α/ATF4.

Endoplasmic reticulum stress: Multiple regulatory roles in hepatocellular carcinoma. Biomed Pharmacother 2021; 142:112005. [PMID: 34426262 DOI: 10.1016/j.biopha.2021.112005] [Citation(s) in RCA: 23] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2021] [Revised: 07/25/2021] [Accepted: 08/01/2021] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Endoplasmic reticulum (ER) stress is a basic cellular stress response that maintains cellular protein homeostasis under endogenous or exogenous stimuli, which depends on the stimulus, its intensity, and action time. The ER produces a corresponding cascade reaction for crosstalk of adaptive and/or pro-death regulation with other organelles. Hepatocellular carcinoma(HCC) is one of the most common malignant solid tumors with an extremely poor prognosis. Viral hepatitis infection, cirrhosis, and steatohepatitis are closely related to the occurrence and development of HCC, and ER stress has gradually been shown to be a major mechanism. Moreover, an increasing need for protein and lipid products and relative deficiencies of oxygen and nutrients for rapid proliferation and endoplasmic reticulum stress are undoubtedly involved. Therefore, to fully and comprehensively understand the regulatory role of endoplasmic reticulum stress in the occurrence and progression of HCC is of vital importance to explore its pathogenesis and develop novel anti-cancer strategies. METHODOLOGY We searched for relevant publications in the PubMed databases using the keywords "Endoplasmic reticulum stress", "hepatocellular carcinoma" in last five years,and present an overview of the current knowledge that links ER stress and HCC, which includes carcinogenesis, progression, and anti-cancer strategies, and propose directions of future research. RESULT ER stress were confirmed to be multiple regulators or effectors of cancer, which also be confirmed to drive tumorigenesis and progression of HCC. Targeting ER stress signaling pathway and related molecules could play a critical role for anti-HCC and has become a research hotspot for anti-cancer in recent years. CONCLUSION ER stress are critical for the processes of the tumorigenesis and progression of tumors. For HCC, ER stress was associated with tumorigenesis, development, metastasis, angiogenesis and drug resistance, targeting ER stress has emerged as a potential anti-tumor strategy.

Abstract
Unraveling the changing rule of endoplasmic reticulum (ER) polarity is of significance for liver injury. However, the rule of the ER polarity changes during the occurrence and progression of liver injury remains a mystery. Toward that, a unique fluorescent probe, ERNT, capable of imaging ER polarity in multiple liver injury models with high accuracy and fidelity was designed herein. In light of its excellent solvatochromism, the ER polarity was determined to be higher in the case of endoplasmic reticulum stress (ERS) induced by tunicamycin and dithiothreitol than that of the normal state at the cell level. Importantly, with the assistance of the PerkinElmer IVIS Spectrum imaging system and the powerful tool of ERNT, our work first revealed that the ER polarity increases with the evolution of liver injuries. Moreover, as a demonstration, ERNT achieved evaluating hepatoprotective drug efficacy by detecting ER polarity, confirming its high clinical application prospect. Thus, our work not only first unravels the rule of ER polarity in dynamic liver injury progression but may also inspire more diagnostic and therapeutic programs for liver diseases shortly.

Endoplasmic reticulum stress and protein degradation in chronic liver disease. Pharmacol Res 2020; 161:105218.

Abstract
Endoplasmic reticulum (ER) stress is easily observed in chronic liver disease, which often causes accumulation of unfolded or misfolded proteins in the ER, leading to unfolded protein response (UPR). Regulating protein degradation is an integral part of UPR to relieve ER stress. The major protein degradation system includes the ubiquitin-proteasome system (UPS) and autophagy. All three arms of UPR triggered in response to ER stress can regulate UPS and autophagy. Accumulated misfolded proteins could activate these arms, and then generate various transcription factors to regulate the expression of UPS-related and autophagy-related genes. The protein degradation process regulated by UPR has great significance in many chronic liver diseases, including non-alcoholic fatty liver disease (NAFLD), alcoholic liver disease (ALD), viral hepatitis, liver fibrosis, and hepatocellular carcinoma(HCC). In most instances, the degradation of excessive proteins protects cells with ER stress survival from apoptosis. According to the specific functions of protein degradation in chronic liver disease, choosing to promote or inhibit this process is promising as a potential method for treating chronic liver disease.

Abstract
As an irreversible and perennial process, aging is accompanied by functional and morphological declines in organs. Generally, aging liver exhibits a decline in volume and hepatic blood flow. Even with a preeminent regenerative capacity to restore its functions after liver cell loss, its biosynthesis and metabolism abilities decline, and these are difficult to restore to previous standards. Apoptosis is a programmed death process via intrinsic and extrinsic pathways, in which Bcl-2 family proteins and apoptosis-related genes, such as p21 and p53, are involved. Apoptosis inflicts both favorable and adverse influences on liver aging. Apoptosis eliminates transformed abnormal cells but promotes age-related liver diseases, such as nonalcoholic fatty liver disease, liver fibrosis, cirrhosis, and liver cancer. We summarize the roles of apoptosis in liver aging and age-related liver diseases.

Abstract
Epidemiological studies have revealed that exposure to PM2.5 is linked to liver cancer. However, the hepatic toxicity and relevant molecular mechanisms of PM2.5 have not yet been fully described. Herein, we report on our investigation of the fibrosis, inflammation, endoplasmic reticulum (ER) stress and apoptosis in the livers of rats, caused by exposure to PM2.5 during summer and winter in Taiyuan, China. Male SD rats were sub-chronically exposed to PM2.5 (in summer: 0.2, 0.6, 1.5 mg per kg of b.w.; in winter: 0.3, 1.5, 2.7 mg per kg of b.w.) via intratracheal instillation once every 3 days for 60 days. The results showed that exposure to high dosages of PM2.5 caused the following: (1) hepatic histopathological changes and liver function decline through elevating the activities of AST, ALT, CYP450 and GST; (2) triggered liver fibrosis, in which TGF-β1, Col I, Col III, and MMP13 mRNA and protein expression were significantly upregulated, and enhanced inflammation with the overexpression of TNF-α, IL-6 and HO-1 versus the control; (3) induced liver ER stress and cell apoptosis via activating the GRP78/ATF6/CHOP/TRB3/caspase 12 pathway. The data also indicated that the liver injury induced by winter PM2.5 in Taiyuan was more serious compared to that induced by summer PM2.5. This work provides new insight into the mechanisms of PM2.5-induced liver injury, and aids the understanding of the underlying mechanisms by which PM2.5 might affect liver diseases.

Abstract
Sanguinarine (SAN), an alkaloid isolated from plants of the Papaveraceae family, is a compound with multiple biological activities. In the present study, we explored the anticancer properties of SAN in lung cancer using the human lung adenocarcinoma cell line SPC-A1. Our results revealed that SAN inhibited SPC-A1 cell growth and induced apoptosis in a dose-dependent manner. We found that SAN triggered reactive oxygen species (ROS) production, while elimination of ROS by N-acetylcysteine (NAC) reversed the growth inhibition and apoptosis induced by SAN. SAN-induced endoplasmic reticulum (ER) stress resulted in the upregulation of many genes and proteins involved in the unfolded protein response (UPR) pathway, including glucose-regulated protein 78 (GRP78), p-protein kinase R (PKR)-like ER kinase (PERK), p-eukaryotic translation initiation factor 2α (eIF2α), activating transcription factor 4 (ATF4) and CCAAT/enhancer binding protein homologous protein (CHOP). Blocking ER stress with tauroursodeoxycholic acid (TUDCA) markedly reduced SAN-induced inhibition of growth and apoptosis. Furthermore, TUDCA decreased SAN-induced ROS production, and NAC attenuated SAN-induced GRP78 and CHOP expression. Overall, our data indicate that the anticancer effects of SAN in lung cancer cells depend on ROS production and ER stress and that SAN may be a potential agent against lung cancer.
