Abstract
This paper represents the first integrative assessment and documentation of taurine-induced hormetic effects in the biological and biomedical areas, their dose response features, mechanistic frameworks, and possible public health, therapeutic and commercial applications. Taurine-induced hormetic effects are documented in a wide range of experimental models, cell types and for numerous biological endpoints, with most of these experimental findings being reported within the past five years. It is suggested that the concept of hormesis may have a transformative effect on taurine research and its public health and therapeutic applications.

Ashruf OS, Ansari MY. Natural Compounds: Potential Therapeutics for the Inhibition of Cartilage Matrix Degradation in Osteoarthritis. LIFE (BASEL, SWITZERLAND) 2022; 13:life13010102. [PMID: 36676051 PMCID: PMC9866583 DOI: 10.3390/life13010102] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/24/2022] [Revised: 12/24/2022] [Accepted: 12/26/2022] [Indexed: 12/31/2022]
Abstract
Osteoarthritis (OA) is the most common degenerative joint disease characterized by enzymatic degradation of the cartilage extracellular matrix (ECM) causing joint pain and disability. There is no disease-modifying drug available for the treatment of OA. An ideal drug is expected to stop cartilage ECM degradation and restore the degenerated ECM. The ECM primarily contains type II collagen and aggrecan but also has minor quantities of other collagen fibers and proteoglycans. In OA joints, the components of the cartilage ECM are degraded by matrix-degrading proteases and hydrolases which are produced by chondrocytes and synoviocytes. Matrix metalloproteinase-13 (MMP-13) and a disintegrin and metalloproteinase with thrombospondin motifs 4 and 5 (ADAMTS5) are the major collagenase and aggrecanase, respectively, which are highly expressed in OA cartilage and promote cartilage ECM degradation. Current studies using various in vitro and in vivo approaches show that natural compounds inhibit the expression and activity of MMP-13, ADAMTS4, and ADAMTS5 and increase the expression of ECM components. In this review, we have summarized recent advancements in OA research with a focus on natural compounds as potential therapeutics for the treatment of OA with emphasis on the prevention of cartilage ECM degradation and improvement of joint health.

Abstract
Xian-Xiong-Gu-Kang is composed of Epimedium brevicornu, Ligusticum chuanxiong, Radix clematidis, Cinnamomum cassia, and Fructus xanthii. It is used to treat numbness and pain of limbs. In this study, we developed a method to simultaneously quantify 11 components of Xian-Xiong-Gu-Kang (icarrin, epimedin A, epimedin B, epimedin C, icariside II, chlorogenic acid, ligustilide, senkyunolide A, senkyunolide I, ferulic acid, and cinnamic acid) in rat plasma using ultra-performance liquid chromatography coupled with quadrupole linear ion trap mass spectrometry. Chromatographic separation was performed on an ACQUITY UPLC BEH C18 column using gradient elution with a mobile phase comprising acetonitrile and 0.05% (v/v) formic acid aqueous solution. Mass spectrometry detection was performed using positive and negative electrospray ionization in the multiple reaction monitoring mode. The calibration curves of the 11 constituents were linear, with correlation coefficients > 0.99. The intra- and interday accuracy and precision values were within ±15.0%. The extraction recoveries of the 11 constituents and two internal standards were between 66.05 and 105.40%, and the matrix effects were between 86.74 and 112.86%. Using this method, the pharmacokinetic features of the 11 constituents were elucidated in the plasma of osteoarthritic rats after oral administration of the Xian-Xiong-Gu-Kang extract.

Med Hypotheses 2018; 118:114-120.

Abstract
Higher dietary intakes of anthocyanins have been linked epidemiologically to decreased risk for metabolic syndrome, type 2 diabetes and cardiovascular events; clinical trials and rodent studies evaluating ingestion of anthocyanin-rich extracts confirm favorable effects of these agents on endothelial function and metabolic syndrome. However, these benefits of anthocyanins are lost in rats whose gut microbiome has been eliminated with antibiotic treatment - pointing to bacterial metabolites of anthocyanins as the likely protective agents. A human pharmacokinetic assessment of orally administered cyanidin-3-O-glucoside, a prominent anthocyanin, has revealed that, whereas this compound is minimally absorbed, ferulic acid (FA) is one of its primary metabolites that appears in plasma. FA is a strong antioxidant and phase 2 inducer that has exerted marked anti-inflammatory effects in a number of rodent and cell culture studies; in particular, FA is highly protective in rodent models of diet-induced weight gain and metabolic syndrome. FA, a precursor for lignan synthesis, is widely distributed in plant-based whole foods, mostly in conjugated form; whole grains are a notable source. Coffee ingestion boosts plasma FA owing to gastrointestinal metabolism of chlorogenic acid. Hence, it is reasonable to suspect that FA mediates some of the broad health benefits that have been associated epidemiologically with frequent consumption of whole grains, anthocyanins, coffee, and unrefined plant-based foods. The molecular basis of the anti-inflammatory effects of FA may have been clarified by a recent study demonstrating that FA can target the adaptor protein MyD88; this plays an essential role in pro-inflammatory signaling by most toll-like receptors and interleukin-1β. If feasible oral intakes of FA can indeed down-regulate MyD88-dependent signaling, favorable effects of FA on neurodegeneration, hypothalamic inflammation, weight gain, adipocyte and beta cell function, adiponectin secretion, vascular health, and cartilage and bone integrity can be predicted. Since FA is well tolerated, safe, and natural, it may have great potential as a protective nutraceutical, and clinical trials evaluating its effects are needed.

Abstract
Oxidative stress and the overproduction of reactive oxygen species (ROS) play an important role in the pathogenesis of osteoarthritis (OA). Accumulating evidence has demonstrated the involvement of microRNAs (miRNAs) dysregulation in disease development and progression. In this study, we evaluated the effect of oxidative stress on miR-146a and miR-34a expression levels in human OA chondrocytes cultures stimulated by H2O2. Mitochondrial ROS production and cell apoptosis were detected by flow cytometry. The antioxidant enzymes SOD-2, CAT, GPx, the transcriptional factor NRF2 and the selected miRNAs were analyzed by qRT-PCR. The H2O2-induced oxidative stress was confirmed by a significant increase in superoxide anion production and of the apoptotic ratio. Furthermore, H2O2 significantly up-regulated the expression levels of SOD-2, CAT, GPx and NRF2, and modulated miR-146a and miR-34a gene expression. The same analyses were carried out after pre-treatment with taurine, a known antioxidant substance, which, in our experience, counteracted the H2O2-induced effect. In conclusion, the induction of oxidative stress affected cell apoptosis and the expression of the enzymes involved in the oxidant/antioxidant balance. Moreover, we demonstrated for the first time the modification of miR-146a and miR-34a in OA chondrocytes subjected to H2O2 stimulus and we confirmed the antioxidant effect of taurine.

Abstract
Matrix metalloproteinase-1 (MMP-1), a member of the matrix metalloproteinases family, plays an integral role in extracellular matrix degradation and has been reportedly involved in the regulation of the brain or spinal cord traumatic neurovascular remodeling. Although the critical involvement of MMP-1 in the metastasis of tumors has been extensively documented, the role of MMP-1 in the pathology of neurological diseases remains largely elusive. In the present study, we established an adult rat spinal cord injury (SCI) model and investigated a potential role of MMP-1 in the pathological process of SCI. Using Western blot analysis, we identified notable expression change of MMP-1 after SCI. Immunohistochemistry showed that MMP-1 was distributed widely in rat spinal cord. Double immunofluorescence staining revealed that MMP-1 immunoreactivity was predominantly increased in neurons and astrocytes following SCI. Moreover, after injury, colocalization of MMP-1/active caspase-3 in neurons (NeuN-positive), and colocalization of MMP-1/PCNA in astrocytes (GFAP-positive) were clearly observed. We also examined the protein expression of PCNA, active caspase-3, Bcl-2, and Bax and found that the expression of the proteins was closely correlated with that of MMP-1. Taken together, our findings indicate that MMP-1 might play an important role in the regulation of neuronal apoptosis and astrocyte proliferation after SCI.

Abstract
Tissue engineering encapsulated cells such as chondrocytes in the carrier matrix have
been widely used to repair cartilage defects. However, chondrocyte phenotype is
easily lost when chondrocytes are expanded in vitro by a process
defined as “dedifferentiation”. To ensure successful therapy, an effective
pro-chondrogenic agent is necessary to overcome the obstacle of limited cell numbers
in the restoration process, and dedifferentiation is a prerequisite. Gallic acid (GA)
has been used in the treatment of arthritis, but its biocompatibility is inferior to
that of other compounds. In this study, we modified GA by incorporating
sulfamonomethoxine sodium and synthesized a sulfonamido-based gallate, JJYMD-C, and
evaluated its effect on chondrocyte metabolism. Our results showed that JJYMD-C could
effectively increase the levels of the collagen II, Sox9, and aggrecan genes, promote
chondrocyte growth, and enhance secretion and synthesis of cartilage extracellular
matrix. On the other hand, expression of the collagen I gene was effectively
down-regulated, demonstrating inhibition of chondrocyte dedifferentiation by JJYMD-C.
Hypertrophy, as a characteristic of chondrocyte ossification, was undetectable in the
JJYMD-C groups. We used JJYMD-C at doses of 0.125, 0.25, and 0.5 µg/mL, and the
strongest response was observed with 0.25 µg/mL. This study provides a basis for
further studies on a novel agent in the treatment of articular cartilage defects.

Abstract
As we previously reported, transcription factor XBP1S enhances BMP2-induced chondrocyte differentiation and acts as a positive mediator of chondrocyte hypertrophy. The purpose of this study was to determine (1) whether XBP1S influences ER stress-mediated apoptosis in osteoarthritis (OA); (2) whether ATF6 regulates IRE1/XBP1 signal pathway in OA cartilage; (3) what are the associated molecules affecting apoptosis in osteoarthritis and the molecular events underlying this process. Herein, we examined and found that ER stress-associated molecules were activated in OA patients, specifically XBP1S splice and expression were increased markedly by TNF-α and IL-1β treatments. Transcription factor ATF6 can specifically bind to the promoter of XBP1 gene and enhance the expression of XBP1S spliced by IRE1α in osteoarthritis cartilage. Furthermore, siXBP1S can enhance ER stress-mediated apoptosis and main matrix degradation in osteoarthritis. Whereas AdXBP1S can inhibit ER stress-mediated apoptosis and TNFα induced nitrite production in OA cartilage. In a word, our observations demonstrate the importance of XBP1S in osteoarthritis. ATF6 and IRE1α can regulate endogenous XBP1S gene expression synergistically in OA cartilage. More significantly, XBP1S was a negative regulator of apoptosis in osteoarthritis by affecting caspase 3, caspase 9, caspase 12, p-JNK1, and CHOP.

Abstract
This study investigated the effect of Angelica sinensis polysaccharides (APS-3c) on rat osteoarthritis (OA) model in vivo and rat interleukin-1-beta- (IL-1β-) stimulated chondrocytes in vitro. APS-3c was administrated into rat OA knee joints and had protective effects on rat OA cartilage in vivo. Primary rat articular chondrocytes were cotreated with APS-3c and IL-1β
in vitro. 2~50 μg/mL APS-3c had no effect on chondrocytes viability, whereas it increased the proteoglycans (PGs) synthesis inhibited by IL-1β. Microarray analysis showed that the significant changes were concentrated in the genes which were involved in PGs synthesis. RT-PCR confirmed that treatment with APS-3c increased the mRNA expression of aggrecan and glycosyltransferases (GTs) inhibited by IL-1β but did not affect the mRNA expression of matrix-degrading enzymes. These results indicate that APS-3c can improve PGs synthesis of chondrocytes on rat OA model in vivo and IL-1β-stimulated chondrocytes in vitro, which is due to the promotion of the expression of aggrecan and GTs involved in PGs synthesis but not the inhibition of the expression of matrix-degrading enzymes. Our findings suggest the clinical relevance of APS-3c in the prospective of future alternative medical treatment for OA.

Abstract
Introduction Sodium ferulate (SF) is a natural component of traditional Chinese herbs. Our previous study shows that SF has a protective effect on osteoarthritis (OA). The objective of this study was to investigate the effect of SF on the TNF/TNF receptor (TNFR) signal transduction pathway of rat OA chondrocytes. Methods Primary rat articular chondrocytes were co-treated with IL-1β and SF. Chondrocyte apoptosis was assessed by fluorescein isothiocyanate-annexin V/propidium iodide assay. The PCR array was used to screen the expression of 84 key genes involved in apoptosis. The release of TNFα and prostaglandin E2 were analyzed by ELISA. Expressions of proteins were assessed by western blotting. The activity of NF-κB was determined by electrophoretic mobility shift assay (EMSA). Gene expression of inducible nitric oxide synthase (iNOS) was evaluated by real-time quantitative PCR. The nitric oxide content was measured with the Griess method. Results After treatment with SF, the apoptosis rate of chondrocytes significantly attenuated (P < 0.01). Results of the apoptosis PCR array suggested that mRNA expression of some core proteins in the TNF/TNFR pathway showed valuable regulation. The protein expressions of TNFα, TNFR-1, TNF receptor-associated death domain, caspase-8 and caspase-3 were prevented by SF in a concentration-dependent manner. SF also inhibited activities of caspase-8 and caspase-3 compared with the OA model control (P < 0.01). TNF receptor-associated factor-2 expression, phosphorylations of inhibitor of NF-κB kinase (IKK) subunits alpha and beta, and NF-κB inhibitor, alpha (IκBα) were all concentration-dependently suppressed by SF treatment. The results of EMSA showed that SF inhibited the activity of NF-κB. In addition, the expressions of cycloxygenase-2 and iNOS and the contents of prostaglandin E2 and NO were attenuated with the treatment of SF (P < 0.01). Conclusion SF has anti-apoptosis and anti-inflammatory effects on an OA model induced by IL-1β in vitro, which were due to inhibitory actions on the caspase-dependent apoptosis pathway and the IKK/NF-κB signal transduction pathway of the TNF/TNFR pathway.
