Abstract
Taurine is a sulfur-containing amino acid found in many cell organelles that plays a wide range of biological roles, including bile salt production, osmoregulation, oxidative stress reduction, and neuromodulation. Taurine treatments have also been shown to ameliorate the onset and development of many diseases, including hypertension, fatty liver, neurodegenerative diseases and ischemia-reperfusion injury, by exerting antioxidant, anti-inflammatory, and antiapoptotic effects. The endoplasmic reticulum (ER) is a dynamic organelle involved in a wide range of cellular functions, including lipid metabolism, calcium storage and protein stabilization. Under stress, the disruption of the ER environment leads to the accumulation of misfolded proteins and a characteristic stress response called the unfolded protein response (UPR). The UPR protects cells from stress and helps to restore cellular homeostasis, but its activation promotes cell death under prolonged ER stress. Recent studies have shown that ER stress is closely related to the onset and development of many diseases. This article reviews the beneficial effects and related mechanisms of taurine by regulating the ER in different physiological and pathological states, with the aim of providing a reference for further research and clinical applications.

Lai KC, Chueh FS, Ma YS, Chou YC, Chen JC, Liao CL, Huang YP, Peng SF. Phenethyl isothiocyanate and irinotecan synergistically induce cell apoptosis in colon cancer HCT 116 cells in vitro. ENVIRONMENTAL TOXICOLOGY 2024; 39:457-469. [PMID: 37792803 DOI: 10.1002/tox.23993] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/18/2023] [Revised: 08/29/2023] [Accepted: 09/21/2023] [Indexed: 10/06/2023]
Abstract
Irinotecan (IRI), an anticancer drug to treat colon cancer patients, causes cytotoxic effects on normal cells. Phenethyl isothiocyanate (PEITC), rich in common cruciferous plants, has anticancer activities (induction of cell apoptosis) in many human cancer cells, including colon cancer cells. However, the anticancer effects of IRI combined with PEITC on human colon cancer cells in vitro were unavailable. Herein, the aim of this study is to focus on the apoptotic effects of the combination of IRI and PEITC on human colon cancer HCT 116 cells in vitro. Propidium iodide (PI) exclusion and Annexin V/PI staining assays showed that IRI combined with PEITC decreased viable cell number and induced higher cell apoptosis than that of IRI or PEITC only in HCT 116 cells. Moreover, combined treatment induced higher levels of reactive oxygen species (ROS) and Ca2+ than that of IRI or PEITC only. Cells pre-treated with N-acetyl-l-cysteine (scavenger of ROS) and then treated with IRI, PEITC, or IRI combined with PEITC showed increased viable cell numbers than that of IRI or PEITC only. IRI combined with PEITC increased higher caspase-3, -8, and -9 activities than that of IRI or PEITC only by flow cytometer assay. IRI combined with PEITC induced higher levels of ER stress-, mitochondria-, and caspase-associated proteins than that of IRI or PEITC treatment only in HCT 116 cells. Based on these observations, PEITC potentiates IRI anticancer activity by promoting cell apoptosis in the human colon HCT 116 cells. Thus, PEITC may be a potential enhancer for IRI in humans as an anticolon cancer drug in the future.

PLXNC1 interference alleviates the inflammatory injury, apoptosis and extracellular matrix degradation of IL-1β-exposed chondrocytes via suppressing GRP78 expression. J Orthop Surg Res 2023; 18:784. [PMID: 37853395 PMCID: PMC10585743 DOI: 10.1186/s13018-023-04207-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/07/2023] [Accepted: 09/13/2023] [Indexed: 10/20/2023] Open
Abstract
BACKGROUND Osteoarthritis (OA) is a frequently encountered debilitating joint disorder. Whether plexin C1 (PLXNC1) is implicated in OA is far from being investigated despite its well-documented pro-inflammatory property in human diseases. The goal of this study is to expound the specific role of PLXNC1 in OA and elaborate the probable action mechanism. METHODS Firstly, PLXNC1 expression in the cartilage tissues of patients with OA was examined with GEO database. In interleukin-1beta (IL-1β)-induced OA cell model, RT-qPCR and western blotting tested the expression of PLXNC1, glucose-regulating protein 78 (GRP78) and extracellular matrix (ECM) degradation-related factors. Cell viability and inflammation were respectively judged by CCK-8 assay and RT-qPCR. TUNEL and western blotting estimated cell apoptosis. The potential binding between PLXNC1 and GRP78 was corroborated by Co-IP assay. Western blotting also tested the expression of endoplasmic reticulum stress (ERS)-associated proteins. RESULTS As it turned out, PLXNC1 expression was elevated in the cartilage tissues of patients with OA and IL-1β-treated chondrocytes. When PLXNC1 was depleted, the viability injury, inflammation, apoptosis and ECM degradation of chondrocytes exposed to IL-1β were obstructed. Besides, GRP78 bond to PLXNC1 in IL-1β-treated chondrocytes. The ascending GRP78 expression in the chondrocytes exposed to IL-1β was depleted after PLXNC1 was silenced. Meanwhile, the impacts of PLXNC1 deficiency on the viability, inflammatory response, apoptosis, ECM degradation as well as ERS in IL-1β-exposed chondrocytes were abolished by GRP78 up-regulation. CONCLUSION In summary, PLXNC1 silencing might interact with and down-regulate GRP78 to mitigate the apoptosis, inflammation, and ECM degradation of IL-1β-insulted chondrocytes in OA.

Effects of dietary oat supplementation on carcass traits, muscle metabolites, amino acid profiles, and its association with meat quality of Small-tail Han sheep. Food Chem 2023; 411:135456. [PMID: 36669340 DOI: 10.1016/j.foodchem.2023.135456] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2022] [Revised: 11/04/2022] [Accepted: 01/08/2023] [Indexed: 01/12/2023]
Abstract
Oat supplementation of the ruminant diet can improve growth performance and meat quality traits, but the role of muscle metabolites has not been evaluated. This study aimed to establish whether oat grass supplementation (OS) of Small-tail Han sheep improved growth performance and muscle tissue metabolites that are associated with better meat quality and flavor. After 90-day, OS fed sheep had higher live-weight and carcass-weight, and lower carcass fat. Muscle metabolomics analysis showed that OS fed sheep had higher levels of taurine, l-carnitine, inosine-5'-monophospgate, cholic acid, and taurocholic acid, which are primarily involved in taurine and hypotaurine metabolism, purine metabolism, and bile acid biosynthesis and secretion, decreased fat accumulation and they promote functional or flavor metabolites. OS also increased muscle levels of amino acids that are attributed to better quality and flavorsome mutton. These findings provided further evidence for supplementing sheep with oat grass to improve growth performance and meat quality.

Abstract
Background Osteoarthritis (OA), mainly caused by severe joint degeneration, is often accompanied by joint pain and dysfunction syndrome. Inflammatory mediators and apoptosis play key roles in the evolution of OA. It is reported that daphnoretin has significant antiviral and anti-tumor values. The present study aims at investigating the role of daphnoretin in OA. Methods The OA mouse model was constructed by performing the destabilization of the medial meniscus through surgery, and the OA cell model was induced in ATDC5 chondrocytes with IL-1β (10 ng/mL) in vitro. Chondrocyte viability and apoptosis were measured by 3-(4,5)-dimethylthiahiazo (-z-y1)-3,5-di-phenytetrazoliumromide (MTT), Caspase-3 activity, and flow cytometry. The levels of COX-2, iNOS, TNF-α, IL-6, Bax, Bcl2, cleaved-Caspase3, endoplasmic reticulum stress (ERS) proteins (GRP78, CHOP, ATF6, and Caspase-12), and NLRP3-ASC-Caspase1 inflammasome were determined by quantitative real-time PCR or western blot. The concentrations of TNF-α, IL-6, and PGE2 were tested by enzyme-linked immunosorbent assay. The content of nitrates was detected by the Griess method. In vivo, morphologic differences in knee joint sections and the thickness of the subchondral bone density plate in mice were observed by hematoxylin–eosin (H&E) staining and safranin O-fast green staining. Results Daphnoretin effectively choked IL-1β-induced chondrocyte apoptosis and facilitated cell viability. Daphnoretin dose-dependently abated ERS, inflammatory mediators, and the activation of NLRP3 inflammasomes in IL-1β-induced chondrocytes. What’s more, in vivo experiments confirmed that daphnoretin alleviated OA progression in a murine OA model by mitigating inflammation and ERS. Conclusion Daphnoretin alleviated IL-1β-induced chondrocyte apoptosis by hindering ERS and NLRP3 inflammasome. Graphical abstract ![]()

Abstract
Osteoarthritis, as a common joint disease among middle-aged and elderly people, has many problems, such as diverse pathogenesis, poor prognosis and high recurrence rate, which seriously affects patients’ physical and mental health and reduces their quality of life. At present, the pathogenesis of osteoarthritis is not completely clear, and the treatment plan is mainly to relieve symptoms and ensure basic quality of life. Therefore, it is particularly urgent to explore the pathogenesis of osteoarthritis. Protein, as organic macromolecule which plays a major role in life activities, plays an important role in the development of disease. Through protein omics, this study found that with the increase of age, excessive sulfur oxidation occurred in endoplasmic reticulum of chondrocytes, which then drove the occurrence of inflammatory reaction, and provided a direction for the follow-up molecular targeted.

Abstract
Taurine, a cysteine-derived zwitterionic sulfonic acid, is a common ingredient in energy drinks and is naturally found in fish and other seafood. In humans, taurine is produced mainly in the liver, and it can also be obtained from food. In target tissues, such as the retina, heart, and skeletal muscle, it functions as an essential antioxidant, osmolyte, and antiapoptotic agent. Taurine is also involved in energy metabolism and calcium homeostasis. Taurine plays a considerable role in bone growth and development, and high-profile reports have demonstrated the importance of its metabolism for bone health. However, these reports have not been collated for more than 10 years. Therefore, this review focuses on taurine-bone interactions and covers recently discovered aspects of taurine's effects on osteoblastogenesis, osteoclastogenesis, bone structure, and bone pathologies (e.g., osteoporosis and fracture healing), with due attention to the taurine-cartilage relationship.

Abstract
Osteoarthritis (OA) is one of the most prevalent conditions in the world, particularly in the developed world with a significant increase in cases and their predicted impact as we move through the twenty-first century and this will be exacerbated by the covid pandemic. The degeneration of cartilage and bone as part of this condition is becoming better understood but there are still significant challenges in painting a complete picture to recognise all aspects of the condition and what treatment(s) are most appropriate in individual causes. OA encompasses many different types and this causes some of the challenges in fully understanding the condition. There have been examples through history where much has been learnt about common disease(s) from the study of rare or extreme phenotypes, particularly where Mendelian disorders are involved. The often early onset of symptoms combined with the rapid and aggressive pathogenesis of these diseases and their predictable outcomes give an often-under-explored resource. It is these "rarer forms of disease" that William Harvey referred to that offer novel insights into more common conditions through their more extreme presentations. In the case of OA, GWAS analyses demonstrate the multiple genes that are implicated in OA in the general population. In some of these rarer forms, single defective genes are responsible. The extreme phenotypes seen in conditions such as Camptodactyly Arthropathy-Coxa Vara-pericarditis Syndrome, Chondrodysplasias and Alkaptonuria all present potential opportunities for greater understanding of disease pathogenesis, novel therapeutic interventions and diagnostic imaging. This review examines some of the rarer presenting forms of OA and linked conditions, some of the novel discoveries made whilst studying them, and findings on imaging and treatment strategies.

Abstract
Discovery of new pharmacological agents is needed to control the progression of osteoarthritis (OA) characterized by progressive joint cartilage damage. Human OA chondrocyte cultures (OAC) were either applied to S-Allyl cysteine (SAC), a sulfur-containing amino acid derivative, or colchicine, an ancient anti-inflammatory therapeutic, for 24 hours. SAC or colchicine did not change viability at 1 nM-10 µM but inhibited p-JNK/pan-JNK. While SAC seems to be more effective, both agents inhibited reactive oxygen species (ROS), 3-nitrotyrosine (3-NT), lipid-hydroperoxides (LPO), advanced lipoxidation end-products (ALEs as 4-hydroxy-2-nonenal, HNE) and advanced glycation end-products (AGEs), and increased glutathione-peroxidase (GPx) and type-II-collagen (COL2). IL-1β, IL-6 and osteopontin (OPN) were more strongly inhibited by SAC than in colchicine. In contrast, TNF-α was inhibited only by SAC, and COX2 only by colchicine. Casp-1/ICE, GM-CSF, receptor for advanced glycation end-products (RAGE) and toll-like receptors (TLR4) were inhibited by both agents, but bone morphogenetic protein 7 (BMP7) was partially inhibited by SAC while induced by colchicine. The nuclear factor erythroid 2-related factor 2 (Nrf2) was induced by SAC; in contrast it was inhibited by colchicine. Although exerting opposite effects on TNF-α, COX2, BMP7 and Nrf2, SAC and colchicine exhibit anti-osteoarthritic properties in OAC by modulating redox sensitive inflammatory signaling.

Molecular and Cellular Effects of Chemical Chaperone-TUDCA on ER-Stressed NHAC-kn Human Articular Chondrocytes Cultured in Normoxic and Hypoxic Conditions. Molecules 2021; 26:molecules26040878.

Abstract
Osteoarthritis (OA) is considered one of the most common arthritic diseases characterized by progressive degradation and abnormal remodeling of articular cartilage. Potential therapeutics for OA aim at restoring proper chondrocyte functioning and inhibiting apoptosis. Previous studies have demonstrated that tauroursodeoxycholic acid (TUDCA) showed anti-inflammatory and anti-apoptotic activity in many models of various diseases, acting mainly via alleviation of endoplasmic reticulum (ER) stress. However, little is known about cytoprotective effects of TUDCA on chondrocyte cells. The present study was designed to evaluate potential effects of TUDCA on interleukin-1β (IL-1β) and tunicamycin (TNC)-stimulated NHAC-kn chondrocytes cultured in normoxic and hypoxic conditions. Our results showed that TUDCA alleviated ER stress in TNC-treated chondrocytes, as demonstrated by reduced CHOP expression; however, it was not effective enough to prevent apoptosis of NHAC-kn cells in either normoxia nor hypoxia. However, co-treatment with TUDCA alleviated inflammatory response induced by IL-1β, as shown by down regulation of Il-1β, Il-6, Il-8 and Cox2, and increased the expression of antioxidant enzyme Sod2. Additionally, TUDCA enhanced Col IIα expression in IL-1β- and TNC-stimulated cells, but only in normoxic conditions. Altogether, these results suggest that although TUDCA may display chondoprotective potential in ER-stressed cells, further analyses are still necessary to fully confirm its possible recommendation as potential candidate in OA therapy.

Abstract
Taurine has been shown to have positive effects on bone mass, which are thought to be due in part to its cytoprotective effects on osteoblasts and here we show that taurine also protects osteocytes against cell death due to reactive oxygen species. Using the IDG-SW3 cell line, the expression of the taurine uptake transporter Taut/Slc6a6 is increased during osteoblast to osteocyte differentiation. Taurine had no effect on genes associated with osteoblast to osteocyte differentiation such as Dmp1, Phex or osteocalcin, even at high doses, but a slight yet significant inhibition of alkaline phosphatase was observed at the highest dose (50 mM). No effect was seen on the osteoclast regulatory genes Rankl and Opg, however the wnt antagonist Sost/sclerostin was potently and dose-dependently downregulated in response to taurine supplementation. Taurine also significantly inhibited Dkk1 mRNA expression, but only at 50 mM. Interestingly, osteocytes were found to also be able to synthesize taurine intracellularly, potentially as a self-protective mechanism, but do not secrete the metabolite. A highly significant increase in the expression of cysteine dioxygenase (Cdo), a key enzyme necessary for the production of taurine, was observed with osteoblast to osteocyte differentiation along with a decrease in methionine, the precursor of taurine. For the first time, we describe the synthesis of taurine by osteocytes, potentially to preserve viability and to regulate bone formation through inhibition of sclerostin.

Abstract
Cartilage comprises a single cell type, the chondrocyte, embedded in a highly complex extracellular matrix. Disruption to the cartilage growth plate leads to reduced bone growth and results in a clinically diverse group of conditions known as genetic skeletal diseases (GSDs). Similarly, long-term degradation of articular cartilage can lead to osteoarthritis (OA), a disease characterised by joint pain and stiffness. As professionally secreting cells, chondrocytes are particularly susceptible to endoplasmic reticulum (ER) stress and this has been identified as a core disease mechanism in a group of clinically and pathologically related GSDs. If unresolved, ER stress can lead to chondrocyte cell death. Recent interest has focused on ER stress as a druggable target for GSDs and this has led to the first clinical trial for a GSD by repurposing an antiepileptic drug. Interestingly, ER stress markers have also been associated with OA in multiple cell and animal models and there is increasing interest in it as a possible therapeutic target for treatment. In summary, chondrocyte ER stress has been identified as a core disease mechanism in GSDs and as a contributory factor in OA. Thus, chondrocyte ER stress is a unifying factor for both common and rare cartilage-related diseases and holds promise as a novel therapeutic target.

Abstract
Endoplasmic reticulum (ER) stress and the related apoptosis and inflammation damage play key roles in osteoarthritis development. The aim of the present work was to investigate the exact role and potential underlying mechanism of pyruvate kinase M2 (PKM2) in rat chondrocytes exposed to interleukin-Iβ (IL-1β). We observed that IL-1β stimulation resulted in an apparent enhancement in PKM2 expression. Additionally, loss of PKM2 evidently ascended cell viability in response to IL-1β exposure. Simultaneously, elimination of PKM2 manifestly repressed IL-1β-stimulated chondrocyte apoptosis, concomitant with attenuated in the proapoptotic protein markers Bax and cleaved caspase-3, and elevated the antiapoptotic protein Bcl-2. In the meanwhile, knockdown of PKM2 ameliorated ER stress in IL-1β-treated chondrocytes, as evidenced by reduced expression of the ER stress-associated proteins GRP78, CHOP, and cleaved caspase-12. Furthermore, PKM2 silencing protected chondrocytes against IL-1β-triggered inflammatory response, as reflected by the downregulated release of proinflammatory mediators, including tumor necrosis factor-α, IL-6, inducible nitric oxide synthase, cyclooxygenase-2, and prostaglandin E2, as well as decreased nitric oxide generation. More important, abrogating PKM2 expression caused a marked decline in Rspo2 expression, and subsequently blocked Wnt/β-catenin signaling. Mechanistically, the Wnt/β-catenin signaling activator Licl effectively impeded the beneficial effects of PKM2 ablation on IL-1β-stimulated apoptosis and inflammatory response. These findings collectively implicated that PKM2 inhibition protected against ER stress-mediated cell apoptosis and inflammatory injury in rat chondrocytes stimulated with IL-1β by inactivating Rspo2-mediated Wnt/β-catenin pathway, and may represented a novel therapeutic target for osteoarthritis.

Abstract
Traditional Chinese medicine for invigorating the kidney and promoting blood circulation is commonly prescribed for the treatment of osteoarthritis associated with kidney deficiency and blood stasis. However, the specific mechanisms of these medicines are still unclear. The present study aimed to evaluate the protective effects of Bugu granules against sodium nitroprusside-induced chondrocyte apoptosis and elucidate the underlying molecular mechanisms. Drug-containing serum was prepared by administering rats with Bugu granules and harvesting the serum. Chondrocytes were exposed to different dilutions of serum, and apoptosis assessed by flow cytometry after staining with annexin V‑FITC/PI. Flow cytometry showed that chondrocyte apoptosis increased significantly after incubation with 2 mol/L sodium nitroprusside for 24 h (t = -48.221, P = 0.000), and the apoptotic rate of chondrocytes decreased with increasing concentrations of drug-containing serum (F = 33.965, P = 0.000). Cellular levels of Trx2, ASK1, caspase‑3, and reactive oxygen species (ROS) were detected by enzyme-linked immunosorbent assay. The cellular content of Trx2 increased gradually with increasing concentrations of drug-containing serum (F = 2610.593, P = 0.000), while that of ASK1 (F = 2473.545, P = 0.000), caspase‑3 (F = 209.921, P = 0.000), and ROS (F = 1666.435, P = 0.000) all decreased significantly. The mRNA expression levels were analyzed by RT-qPCR, which revealed that expression levels of Trx2 and caspase‑3 mRNA increased and decreased significantly, respectively, following exposure to Bugu granules in the drug-containing serum (F = 6.974, P = 0.003 and F = 3.691, P = 0.191; respectively), but the expression of ASK1 mRNA was not significantly different between treatment groups (F = 1.784, P = 0.191). Taken together, these results support the hypothesis that the Trx2 signaling pathway is activated by Bugu granules, which in turn inhibits chondrocyte apoptosis. This may play a role in preventing the development of osteoarthritis.

Abstract
Osteochondritis dissecans (OCD) in equids, especially in sport horses, has become a growing issue as it contributes to the occurrence of lameness. Thus the aim of this study was to investigate the cytophysiological properties of OCD chondrocytes including expression of chondrogenic genes, apoptosis, mitochondria dynamics and autophagy. Horse chondrocytes were isolated from healthy (HE) and OCD cartilages. Properties of cells were evaluated using multiple assays e.g., polymerase chain reaction (PCR), immunofluorescence, Western blot. OCD chondrocytes were characterized by increased apoptosis and senescence. Expression of chondrogenic genes (vimentin, aggrecan) was decreased while mRNA levels of matrix metalloproteinase 13 significantly upregulated in comparison to HE cells. Moreover, OCD cells displayed increased mitochondrial fusion while fission events were diminished. Interestingly, chaperone mediated autophagy was triggered in those cells and it predominated over macroautophagy. Furthermore, co-culture of LPS-treated chondrocytes with adipose-derived stem cells (ASC) decreased p62/sequestosome 1 (SQSTM) and increases MMP-13 expression in OCD cells. Our results suggest that OCD affected horse chondrocytes are characterized by senescent phenotype due to endoplasmic reticulum stress and mitochondria dynamics deterioration. Expression of chondrogenic markers is decreased in those cells while expression of chaperone mediated autophagy (CMA)-related genes increased. Increased malfunctioning of cells leads to loss of their functionality and capacity to maintain tissue homeostasis.

Abstract
Osteoarthritis (OA) affects elderly population worldwide and endoplasmic
reticulum (ER) stress is known to be positively correlated with OA development.
Previous reports prove the cytoprotective effects of baicalin on chondrocytes,
whereas the mechanisms are hardly reported. Hence, we aimed to investigate the
links between OA, ER stress, and baicalin. Chondrocytes from patients with OA
were subjected to H2O2 treatment with or without baicalin
pretreatment, and cell viability was assessed via Cell Counting Kit-8. Messenger
RNA (mRNA) amounts of apoptosis-related genes (Bax, Bcl-2, and Caspase-3),
extracellular matrix (ECM)-related genes (Collange I, Collange II, Aggrecan, and
Sox9) and ER stress hallmarks (binding immunoglobulin protein [BiP] C/EBP
homologous protein [CHOP]) were evaluated via quantitative real-time PCR. Bax,
Bcl-2, BiP, and CHOP protein levels were analyzed via Western blot. Baicalin
suppressed the changes in cell viability and apoptosis-related gene expressions
caused by H2O2. Reactive oxygen species and
glutathione/oxidized glutathione assay showed that H2O2
enhanced oxidative stress. Baicalin suppressed
H2O2-induced downregulation of mRNA expression of
ECM-related genes. Moreover, baicalin reduced
H2O2-stimulated increase in oxidative stress and the
expression of ER stress hallmarks. Endoplasmic reticulum stress inducer
abolished the protective activities, whereas ER stress inhibitor did not exhibit
extra protective effects. Baicalin pretreatment protected patient-derived
chondrocytes from H2O2 through ER stress inhibition.
