Abstract
Knee osteoarthritis (KOA) stands as a degenerative ailment with a substantial and escalating prevalence. The practice of traditional Chinese non-pharmacological therapy has become a prevalent complementary and adjunctive approach. A mounting body of evidence suggests its efficacy in addressing KOA. Recent investigations have delved into its underlying mechanism, yielding some headway. Consequently, this comprehensive analysis seeks to encapsulate the clinical application and molecular mechanism of traditional Chinese non-pharmacological therapy in KOA treatment. The review reveals that various therapies, such as acupuncture, electroacupuncture, warm needle acupuncture, tuina, and acupotomy, primarily target localized knee components like cartilage, subchondral bone, and synovium. Moreover, their impact extends to the central nervous system and intestinal flora. More perfect experimental design and more comprehensive research remain a promising avenue in the future.

Int J Mol Med 2021; 47:34. [PMID: 33537813 PMCID: PMC7891823 DOI: 10.3892/ijmm.2021.4867] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2020] [Accepted: 12/29/2020] [Indexed: 12/23/2022] Open
Abstract
The activation of oxidative stress is a primary cause of chondrocyte apoptosis in osteoarthritis (OA). The 78‑kDa glucose‑regulated protein (GRP78)/mammalian target of rapamycin (mTOR) signaling pathway has been demonstrated to be linked with the endoplasmic reticulum (ER) and autophagy. Hydrogen sulfide (H2S) has been reported to exert antioxidant effects. The present study investigated oxidative stress levels via 2',7'‑dichlorofluorescin diacetate and MitoSOX staining, apoptosis rates via flow cytometry and the expression levels of ER stress‑related proteins in GYY4137 (donor of H2S)‑treated chondrocytes (CHs). CHs were isolated from the bilateral hip joints of male rats to examine mitochondrial permeability transition pore opening‑ and mTOR signaling pathway‑related proteins. The results demonstrated that tert‑Butyl hydroperoxide (TBHP) increased CH apoptosis, and treatment with GYY4137 ameliorated TBHP‑mediated the generation of ROS and CH apoptosis. Moreover, TBHP‑treated CHs displayed elevated ER stress sensor expression levels and apoptotic rates; however, the TBHP‑induced protein expression levels were decreased following GYY4137 treatment. In the present study, treatment with either GYY4137 or transfection with GRP78 siRNA both suppressed the activation of p‑P70S6k and p‑mTOR. H2S played an important role in regulating ER stress in TBHP‑stimulated CHs. GYY4137 promoted autophagy, which was accompanied by the inhibition of ER stress. On the whole, the present study demonstrates that TBHP‑induced oxidative stress stimulates ER interactions and CH apoptosis, which are suppressed by exogenous H2S via modulating the GRP78/mTOR signaling pathway.

AQUATIC TOXICOLOGY (AMSTERDAM, NETHERLANDS) 2020; 229:105657. [PMID: 33075616 DOI: 10.1016/j.aquatox.2020.105657] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/04/2020] [Revised: 10/05/2020] [Accepted: 10/06/2020] [Indexed: 06/11/2023]
Abstract
Hydrogen peroxide (H2O2) appears to be ubiquitous in natural water. Higher level of H2O2 can cause physiological stress, immunosuppression and even death in aquatic animals, but the physiological and molecular mechanisms of H2O2 toxicity are not well studied. Thus, the aim of the present study was to exposure potential toxic mechanisms of H2O2 via assessing the effects on redox state, apoptosis and endoplasmic reticulum (ER) stress in common carp. The fish were subjected to four concentrations of H2O2 (0, 0.25, 0.5 and 1 mM) for 14 days. And then, the tissues including blood, liver, muscle, gills, intestines, heart, kidney and spleen were collected to measure biochemical parameter and gene expression. The results showed that H2O2 exposure suppressed the majority antioxidative parameters in serum, liver, muscle and intestines, but enhanced T-SOD, CAT and T-AOC levels in gills. In all tested tissues, the MDA content was significantly promoted by H2O2 exposure. The oxidative stress-related genes including nrf2, gstα, sod, cat and/or gpx1 were upregulated in liver, gills, muscle, intestines, and/or kidney, but downregulated in heart after H2O2 exposure. Moreover, the ho-1 mRNA level was inhibited by H2O2 exposure in all tissues except intestines and spleen. After 14 days of exposure, H2O2 induced ER stress and initiated IRE1 and PERK pathways, which activated downstream genes, including chop, grp78 and/or xbp1s, to regulate UPR in liver, gills, muscle and/or heart. Meanwhile, H2O2 exposure activated MAPK pathway to regulate mitochondria-related genes including bcl-2, bax and cytc, which further triggered cas-8, cas-9 and cas-3, and accelerated apoptosis in liver, gills, muscle and heart. Importantly, in different tissues, the genes associated with oxidative stress, ER stress and apoptosis showed a different influence, and more significant influence was observed in the muscle, gills and liver. Overall results suggested that long-term H2O2 exposure induced oxidative stress, ER stress and apoptosis in the majority of tested tissues of common carp. The Nrf2, IRE1, PERK and MAPK pathways played important roles in H2O2-induced toxicity in fish. These data enriched the toxicity mechanism of H2O2 in fish, which might contribute to the risk assessment of H2O2 in aquatic environment.

Abstract
Osteoarthritis (OA) is the most common disabling joint disease and its pathological process is closely related to oxidative stress. Recent studies have shown that antioxidants allicin, sulforaphane, and lycopene derived from natural ingredients garlic, broccoli, and tomato can reduce the degree of oxidative stress and the expression of inflammatory markers, indicating that theses antioxidants might be helpful for OA treatment. In this study, we investigated the effects of allicin, sulforaphane, and lycopene on H2O2-stimulated human osteochondral samples and osteoarthritic chondrocytes. Our results revealed that allicin, sulforaphane, and lycopene effectively reduced the oxidative stress-induced cell apoptosis, and increased gene expression of antioxidant enzymes. Besides, these natural ingredients-derived antioxidants reduced the expression of inflammatory factors, enhanced the chondrogenic matrix synthesis, and reduced the hypertrophic differentiation of osteoarthritic chondrocytes. These regulations were mainly through the activation of Keap1/Nrf2 pathway. Our findings suggest that these antioxidants might be a potential therapeutic strategy for OA.

Abstract
Background Chondrocyte apoptosis activated by the mitochondrial dependent pathway serves a crucial role in cartilage degeneration of osteoarthritis (OA). In the present study, the protective effects of CMCS against sodium nitroprusside (SNP)-induced chondrocyte apoptosis were evaluated and the underlying molecular mechanisms were elucidated. Methods Chondrocytes were isolated from articular cartilage of SD rats and identified by type II collagen immunohistochemistry. The chondrocytes stimulated with or without SNP to induce apoptosis, were treated by CMCS for various concentrations. The cell viability were determined by MTT and LDH assays. Cell apoptotic ratio was determined by Annexin V-FITC/PI staining. Mitochondrial membrane potential (ΔΨm) was detected by using Rhodamine123 (Rho123) staining. To understand the mechanism, the mRNA expression levels of Bcl-2, Bax, cytochrome c (Cyt c) and cleaved caspase-3 were detected by real-time PCR and western blot analysis, respectively. Results It was shown using the MTT and LDH assays that CMCS protected the viability of chondrocyte against SNP damage. Annexin V-FITC/PI and Rho123 staining showed that CMCS not only inhibited the cell apoptosis but also restored the reduction of the ΔΨm in chondrocytes. In SNP-induced chondrocytes, CMCS down-regulated the expression of Bax, Cyt c and cleaved caspase-3 but upregulated the expression of Bcl-2, as shown by real-time PCR and western blot. Conclusions Taken together, these results indicated that CMCS has the protective effect on chondrocytes against SNP-induced apoptosis, at least partly, via inhibiting the mitochondrial dependent apoptotic pathway. Thus, CMCS may be potentially used as a biological agent for prevention and treatment of OA.

Role of the PERK-eIF2 α-CHOP Signaling Pathway in the Effect of Needle Knife Therapy on Knee Joint Chondrocyte Apoptosis. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2019; 2019:7164916.

Abstract
Needle knife therapy, a form of acupuncture and moxibustion, has been widely used in the clinical treatment of knee osteoarthritis (KOA). However, the mechanism is not clear. Therefore, we studied the mechanisms of action of needle knife intervention on KOA in rabbits, with the PERK-eIF2α-CHOP pathway as a starting point, in order to determine the mechanism underlying knee joint chondrocyte apoptosis. Apoptosis and ultrastructural changes in the articular cartilage were examined by pathological study and transmission electron microscopy, and PERK, eIF2α, and CHOP mRNA and protein levels were detected by qRT-PCR and western blot, respectively. PERK, eIF2α, and CHOP protein levels were significantly higher in the model group than in the normal group (P < 0.01) and were considerably downregulated in the needle knife and the medicine groups compared to the model group (P < 0.01). The eIF2α, p-eIF2α, and CHOP protein levels were not significantly different between the needle knife and medicine groups. The PERK, eIF2α, and CHOP mRNA levels in the drug group were higher than those in the needle knife group (P < 0.01). Needle knife therapy can regulate PERK-eIF2α-CHOP signaling pathway, which could be one of the mechanisms by which it affects chondrocyte apoptosis in KOA rabbits.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Tougu Xiaotong capsule (TXC) is a Chinese herbal compound that belongs to a range of Chinese herbs functioning as 'kidney invigorators and liver softeners' commonly used to treat osteoarthritis (OA) in China. AIMS OF THE STUDY The aims of the present study are to confirm the therapeutic effects of TXC in an OA cell model and to determine the mechanisms involved in such effects. MATERIALS AND METHODS A tunicamycin (Tm)-exposed OA cell model was employed, and the effects of TXC were confirmed by observing cell viability and apoptosis. The reduced cell viability and increased apoptosis caused by Tm were improved by TXC, confirming the cellular protection of TXC. We then investigated the expression of biomarkers related to the endoplasmic reticulum (ER) stress pathway, including microRNA-211 (miR-211), a regulator in the ER stress pathway. RESULTS Downregulation of X-box binding protein 1 (Xbp-1) and miR-211 expression following Tm administration was reversed by TXC. Moreover, the upregulation by Tm of the expression levels of binding immunoglobulin protein, Xbp-1, activating transcription factor 4, C/EBP-homologous protein, Caspase-9 and Caspase-3 was downregulated by TXC. These results indicated that the ER stress pathway-related mechanism may play a potential role in the therapeutic effects of TXC. CONCLUSIONS The present study provides evidence of the therapeutic effects of TXC at the cell level and describes a cellular model for establishing the mechanisms of the effects of TXC used in the treatment of OA.

Abstract
Accumulating evidence suggests that autophagy plays a protective role in chondrocytes and prevents cartilage degeneration in osteoarthritis (OA). The objective of this study was to investigate the effect of diazoxide on chondrocyte death and cartilage degeneration and to determine whether these effects are correlated to autophagy in experimental OA. In this study, a cellular OA model was established by stimulating SW1353 cells with interleukin 1β. A rat OA model was generated by transecting the anterior cruciate ligament combined with the resection of the medial menisci, followed by treatment with diazoxide or diazoxide combination with 3-methyladenine. The percentage of viable cells was evaluated using calcein-acetoxymethyl/propidium iodide double staining. The messenger RNA expression levels of collagen type II alpha 1 chain (COL2A1), matrix metalloproteinase 13 (MMP-13), TIMP metallopeptidase inhibitor 1 (TIMP-1), and a disintegrin and metalloproteinase with thrombospondin motifs 5 (ADAMTS5) were determined using quantitative real-time polymerase chain reaction. The cartilage thickness and joint space were evaluated using ultrasound. SW1353 cell degeneration and autophagosomes were observed using transmission electron microscopy. The expression levels of microtubule-associated protein 1 light chain 3 (LC3), beclin-1, P62, COL2A1, and MMP-13 were evaluated using immunofluorescence staining and Western blot analysis. Diazoxide significantly attenuated articular cartilage degeneration and SW1353 cell death in experimental OA. The restoration of autophagy was observed in the diazoxide-treated group. The beneficial effects of diazoxide were markedly blocked by 3-methyladenine. Diazoxide treatment also modulated the expression levels of OA-related biomarkers. These results demonstrated that diazoxide exerted a chondroprotective effect and attenuated cartilage degeneration by restoring autophagy via modulation of OA-related biomarkers in experimental OA. Diazoxide treatment might be a promising therapeutic approach to prevent the development of OA.
