Abstract
Background Complementary/alternative medicine" (CAM) is defined as a diverse range of medical treatments, largely non-allopathic, mostly traditional, and not integrated into the authoritarian healthcare system. Interestingly for some schools, allopathy is alternative/complementary therapy. Osteoporosis is an ever-known disease treated before the era of allopathic medicine. Even though the customary medical system of India is among the most well-known in the world, every continent has its own alternative therapies for various chronic diseases. Purpose This review of the scientific information is to help the readers understand how crucial the conceptual underpinnings of alternative medical therapy systems are to the advancement of conventional allopathic practices. Method Many older and recent articles about alternative medical therapy in the management of osteoporosis published in scientific journals are reviewed. Relevant information from cross-references on methods of evaluating the efficacy of different modalities and their scientific pathways is included. An effort has been made to summarise the treatment of osteoporosis by these systems. Opinions, impressions, and inferences are added while describing various aspects of these modalities. Result The National Library of Medicine has played an active role in publishing studies of the management of osteoporosis by alternative therapies. Many issues of management of osteoporosis still lack reliable treatment. However, good information is now available about choosing alternate medical therapy that has been studied scientifically and has shown promising results. Conclusion Medicinal plants and certain natural treatments can treat osteoporosis and its problems. The use of alternate medical therapy has been proven recently by clinical practice and conventional wisdom. This sharing may help the medical practitioner to understand and judiciously allow complementary therapy while treating osteoporosis.

[PMID: 36687056 PMCID: PMC9851025 DOI: 10.1021/acsomega.2c07094] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/04/2022] [Accepted: 12/23/2022] [Indexed: 06/17/2023]
Abstract
PURPOSE As a traditional herb product, the root of Caragana sinica (Buc'hoz) Rehder (Chinese name: Jin Quegen [JQG]) has been widely used in folk medicines for rheumatoid arthritis (RA) treatment. However, which herbal constituents exert a core pharmacological role in RA treatment remains a great challenge due to the multiple phytochemical constituents, targets, and pathways. In this work, we aimed to use a new strategy to explore the core herbal constituents and potential mechanisms of JQG against RA for the first time. METHODS A successively partitioned extract of JQG, bioactive partition screening in vitro and in vivo, qualitative analysis, bioinformatic analysis, molecular docking, and mechanism validation were used in this study. The partitioned extract was used to obtain the bioactive partition, while in vitro anti-inflammatory effects and in vivo anti-arthritis effects in adjuvant-induced arthritis (AIA) rats were applied to screen the bioactive partition with the best efficacy. Qualitative analysis was used to identify bioactive constituents. Bioinformatic analysis was used to explore the potential mechanism for RA treatment. Molecular docking and immunofluorescence were used to validate the underlying mechanism. RESULTS After successively partitioning extract and bioactive partition screening, ethyl acetate extract (EAE) yielded the best anti-inflammatory effects in vitro and in vivo among JQG extracts. By ultra-performance liquid chromatography (UPLC) coupled with Orbitrap mass spectrometry, a total of 58 constituents were identified in EAE, and 17 constituents were regarded as the core constituents based on their oral bioavailability and drug-like properties. The nuclear factor kappa B (NF-κB) signal pathway was screened as the core pathway of core constituents for RA treatment based on bioinformatic analysis, and the core constituents showed good ligand-receptor binding activity to NF-κB P65. In vitro study demonstrated that EAE could significantly reduce NF-κB P65 transfer from the cytoplasm to the nucleus. CONCLUSION Our study suggested that the therapeutic efficacy of JQG for RA treatment could be derived from negative regulation of the NF-κB pathway, and EAE of JQG could represent a promising herb product for RA treatment that deserves further development.

Peng Z, Xu R, You Q. Role of Traditional Chinese Medicine in Bone Regeneration and Osteoporosis. Front Bioeng Biotechnol 2022; 10:911326. [PMID: 35711635 PMCID: PMC9194098 DOI: 10.3389/fbioe.2022.911326] [Citation(s) in RCA: 37] [Impact Index Per Article: 18.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2022] [Accepted: 05/12/2022] [Indexed: 12/21/2022] Open
Abstract
According to World Health Organization (WHO), osteoporosis is a systematic bone disability marked by reduced bone mass and microarchitectural degeneration of osseous cells, which leads to increased bones feebleness and fractures vulnerability. It is a polygenetic, physiological bone deformity that frequently leads to osteoporotic fractures and raises the risk of fractures in minimal trauma. Additionally, the molecular changes that cause osteoporosis are linked to decreased fracture repair and delayed bone regeneration. Bones have the ability to regenerate as part of the healing mechanism after an accident or trauma, including musculoskeletal growth and ongoing remodeling throughout adulthood. The principal treatment approaches for bone loss illnesses, such as osteoporosis, are hormone replacement therapy (HRT) and bisphosphonates. In this review, we searched literature regarding the Traditional Chinese medicines (TCM) in osteoporosis and bone regeneration. The literature results are summarized in this review for osteoporosis and bone regeneration. Traditional Chinese medicines (TCM) have grown in popularity as a result of its success in curing ailments while causing minimal adverse effects. Natural Chinese medicine has already been utilized to cure various types of orthopedic illnesses, notably osteoporosis, bone fractures and rheumatism with great success. TCM is a discipline of conventional remedy that encompasses herbal medication, massage (tui na), acupuncture, food, and exercise (qigong) therapy. It is based on more than 2,500 years of Chinese healthcare profession. This article serves as a comprehensive review summarizing the osteoporosis, bone regeneration and the traditional Chinese medicines used since ancient times for the management of osteoporosis and bone regeneration.

Abstract
Tumor necrosis factor (TNF) is a regulator of several chronic inflammatory diseases, such as rheumatoid arthritis. Although anti-TNF biologics have been used in clinic, they render several drawbacks, such as patients' progressive immunodeficiency and loss of response, high cost, and intravenous administration. In order to find new potential anti-TNF small molecule inhibitors, we employed an in silico approach, aiming to find natural products, analogs of Ampelopsin H, a compound that blocks the formation of TNF active trimer. Two out of nine commercially available compounds tested, Nepalensinol B and Miyabenol A, efficiently reduced TNF-induced cytotoxicity in L929 cells and production of chemokines in mice joints' synovial fibroblasts, while Nepalensinol B also abolished TNF-TNFR1 binding in non-toxic concentrations. The binding mode of the compounds was further investigated by molecular dynamics and free energy calculation studies, using and advancing the Enalos Asclepios pipeline. Conclusively, we propose that Nepalensinol B, characterized by the lowest free energy of binding and by a higher number of hydrogen bonds with TNF, qualifies as a potential lead compound for TNF inhibitors' drug development. Finally, the upgraded Enalos Asclepios pipeline can be used for improved identification of new therapeutics against TNF-mediated chronic inflammatory diseases, providing state-of-the-art insight on their binding mode.

Abstract
Osteoarthritis (OA) is a common joint disease characterized by degradation and inflammation of cartilage extracellular matrix. We aimed to evaluate the protective effect of Caragana sinica root (CSR) on interleukin (IL)-1β-stimulated rat chondrocytes and a monosodium iodoacetate (MIA)-induced model of OA. In vitro, cell viability of CSR-treated chondrocytes was measured by MTT assay. The mRNA expression of Matrix metallopeptidases (MMPs), a disintegrin and metalloproteinase with thrombospondin motifs (ADAMTSs) and extracellular matrix (ECM) were analyzed by quantitative real-time PCR (qRT-PCR). Moreover, the protein expression of MAPK (phosphorylation of EKR, JNK, p38), inhibitory kappa B (IκBα) and nuclear factor-kappa B (NF-κB p65) was detected by western blot analysis. In vivo, the production of nitric oxide (NO) was detected by Griess reagent, while those of inflammatory mediators, MMPs and ECM were detected by ELISA. The degree of OA was evaluated by histopathological analyses, Osteoarthritis Research Society International (OARSI) score and micro-CT analysis. CSR significantly inhibited the expression of MMPs, ADAMTSs and the degradation of ECM in IL-1β-stimulated chondrocytes. Furthermore, CSR significantly suppressed IL-1β-stimulated of MAPKs, NF-κB signaling pathway. In vivo, CSR and Indomethacin inhibited the production of inflammatory mediators, MMPs and degradation of ECM in MIA-induced model of OA. In addition, CSR improved the severity of OA. Taken together, these results suggest CSR is a potential therapeutic active agent in the treatment of OA.

Aluminum trichloride caused hippocampal neural cells death and subsequent depression-like behavior in rats via the activation of IL-1β/JNK signaling pathway. THE SCIENCE OF THE TOTAL ENVIRONMENT 2020; 715:136942.

Abstract
Aluminum (Al) is an inorganic pollutant that induces nerve cells apoptosis and necroptosis, thereby causing depression and neurodegenerative diseases. IL-1β/JNK signaling pathway can regulate apoptosis and necroptosis. However, it remains unclear whether IL-1β/JNK signaling pathway is involving in the regulation of Al-induced hippocampal neural cells apoptosis and necroptosis. To investigate the mechanism of Al on neural cells apoptosis and necroptosis, rats were orally exposed to different doses of AlCl3 for 90 days. The open-field test results showed that AlCl3 caused depressive behavior in rats. Histopathological evidence showed that AlCl3 induced hippocampal neural cells apoptosis and necrosis. Moreover, Bax/Bcl-2 mRNA expression ratio, caspase-3 activity and mRNA expression and TUNEL positive rates were upregulated, meanwhile, TNF-α mRNA and protein expression levels, TNFR1, RIP1, RIP3 and MLKL proteins levels were increased, while caspase-8 protein level was decreased in the hippocampus of Al-exposed groups. These results proved that AlCl3 induced hippocampal neural cells apoptosis and necroptosis. Combined with histopathology and correlation analysis, we deduced that hippocampal neural cells were more likely to undergo necroptosis at high doses (450 mg/kg) of AlCl3, while <150 mg/kg AlCl3 tended to induce apoptosis. Finally, AlCl3 increased the proteins level of IL-1β, IL-1RI, IL-1RAcP, JNK and p-JNK, indicating that AlCl3 activated IL-1β/JNK signaling pathway. However, the application of IL-1 receptor antagonist (IL-1Ra) inhibited the phosphorylation of JNK and the related genes expression of apoptosis and necroptosis caused by AlCl3. Thus, we concluded that AlCl3 induced hippocampal neural cells death and depression-like behavior in rats by activating IL-1β/JNK signaling pathway.

Abstract
The ubiquitous proteoglycan, biglycan (BGN) acts as an important modulator, regulating key molecular pathways of metabolism and brain function. Autophagy is documented as a defining feature of neurodegeneration in Alzheimer's disease (AD), Parkinson's disease (PD), and Huntington's disease (HD). In the present study, we found that BGN protected neuronal cells from nitric oxide (NO)-induced cell apoptosis. However, it is still unclear that whether the neuroprotective effect of BGN relates to autophagy. Here, we discovered that an NO donor, sodium nitroprusside (SNP) induced autophagy in human SH-SY5Y neuroblastoma cells, including activating LC3B and inhibiting p62. Inhibiting autophagy by 3MA aggravated NO-induced cell death, otherwise promoting autophagy by Rapamycin rescued NO-triggered cell death. Notably, BGN downregulated by NO, significantly protected SH-SY5Y cells against NO-induced neurotoxicity by inhibiting the activation of autophagy-dependent AMPK signaling pathway. Moreover, BGN overexpression also diminished NO-induced the elevation of intracellular reactive oxygen species (ROS) level, but not NO content. These findings suggest that BGN protects neuroblastoma cells from NO-induced death by suppressing autophagy-dependent AMPK-mTOR signaling and intracellular ROS level.

Abstract
Kobophenol A (KPA) is a biologically active natural compound isolated from the roots of Caragana sinica (Buc'hoz) Rehder (C. sinica). However, the anti-inflammatory effects of KPA have not been reported. This study aims to find out whether KPA isolated from roots of C. sinica can act as a potential substance on inflammation and analyze the molecular mechanism using the lipopolysaccharide (LPS)-stimulated J774 A.1 macrophage cell line. We showed that KPA treatment significantly suppressed the production of nitric oxide (NO) by inhibiting inducible nitric oxide synthase (iNOS) expression in a dose-dependent manner without cytotoxicity. In the KPA also inhibited pro-inflammatory cytokine gene expression and production, such as interleukin-1β (IL-1β) and interleukin-6 (IL-6) in LPS-stimulated J774 A.1 cells. As continuing study on the mechanisms involved, we confirmed that these effects of KPA were related to the inhibition of nuclear factor-κB (NF-κB) pathway including the suppression of IκB kinase α/β (IKKα/β) phosphorylation and translocation of NF-κB into the nucleus. Taken together, the present study is the first to demonstrate that KPA isolated from C. sinica suppresses the expression of inflammatory mediators and cytokines by inhibiting NF-κB nuclear translocation in LPS-stimulated J774 A.1 macrophages. KPA may be a potential candidate for the treatment of inflammatory diseases in the future.

RNA-binding protein RBM3 prevents NO-induced apoptosis in human neuroblastoma cells by modulating p38 signaling and miR-143. Sci Rep 2017; 7:41738.

Abstract
Nitric oxide (NO)-induced apoptosis in neurons is an important cause of neurodegenerative disease in humans. The cold-inducible protein RBM3 mediates the protective effects of cooling on apoptosis induced by various insults. However, whether RBM3 protects neural cells from NO-induced apoptosis is unclear. This study aimed to investigate the neuroprotective effect of RBM3 on NO-induced apoptosis in human SH-SY5Y neuroblastoma cells. Firstly, we demonstrated that mild hypothermia (32 °C) induces RBM3 expression and confers a potent neuroprotective effect on NO-induced apoptosis, which was substantially diminished when RBM3 was silenced by siRNA. Moreover, overexpression of RBM3 exhibited a strong protective effect against NO-induced apoptosis. Signaling pathway screening demonstrated that only p38 inhibition by RBM3 provided neuroprotective effect, although RBM3 overexpression could affect the activation of p38, JNK, ERK, and AKT signaling in response to NO stimuli. Notably, RBM3 overexpression also blocked the activation of p38 signaling induced by transforming growth factor-β1. Furthermore, both RBM3 overexpression and mild hypothermia abolished the induction of miR-143 by NO, which was shown to mediate the cytotoxicity of NO in a p38-dependent way. These findings suggest that RBM3 protects neuroblastoma cells from NO-induced apoptosis by suppressing p38 signaling, which mediates apoptosis through miR-143 induction.

Abstract
Macrophage-associated nitric oxide (NO) production plays a crucial role in the pathogenesis of tissue damage. However, negative factors that regulate NO production remains poorly understood despite its significance of NO homeostasis. Here, we show that activating transcription factor 3 (ATF3), a transcriptional regulator of cellular stress responses, was strongly induced in activated macrophages and its depletion resulted in pronounced enhancement of inducible nitric oxide synthase (iNOS) gene expression and subsequently the induction of high levels of NO production. In response to lipopolysaccharide (LPS) and IFN-γ, ATF3 inhibited transcriptional activity of NF-κB by interacting with the N-terminal (1-200 amino acids) of p65 and was bound to the NF-κB promoter, leading to suppression of iNOS gene expression. In addition, inhibitory effects of ATF3 on iNOS and NO secretion were suppressed by inhibitor of casein kinase II (CK2) activity or its knockdown. Moreover, the levels of ATF3 were highly elevated in established cecal ligation and puncture or LPS-injected mice, a model of endotoxemia. ATF3 is also elevated in peritoneal macrophages. Collectively, our findings suggest that ATF3 regulates NO homeostasis by associating with NF-κB component, leading to the repression of its transcriptional activity upon inflammatory signals and points to its potential relevance for the control of cell injuries mediated by NO during macrophage activation.

Abstract
Echinochrome A (EchA) is a dark-red pigment of the polyhydroxynaphthoquinone class isolated from sea urchin Scaphechinus mirabilis. Acetylcholinesterase (AChE) inhibitors are used in the treatment of various neuromuscular disorders, and are considered as strong therapeutic agents for the treatment of Alzheimer's disease (AD). Although EchA is clinically used to treat ophthalmic diseases and limit infarct formation during ischemia/ reperfusion injury, anti-AChE effect of EchA is still unknown. In this study, we investigated the anti-AChE effect of EchA in vitro. EchA and its exhausted form which lost anti-oxidant capacity did not show any significant cytotoxicy on the H9c2 and A7r5 cells. EchA inhibited AChE with an irreversible and uncompetitive mode. In addition, EchA showed reactive oxygen species scavenging activity, particularly with nitric oxide. These findings indicate new therapeutic potential for EchA in treating reduced acetylcholine-related diseases including AD and provide an insight into developing new AChE inhibitors.

Abstract
Aluminum (Al) is considered to be a potentially toxic metal. Al exposure inhibits bone formation. Few studies have investigated the mechanism of inhibitory effects of Al on bone formation. Thus, in this study, osteoblasts were cultured and exposed to different concentrations of Al to investigate the mechanism behind the inhibitory effects of Al on bone formation. Al-treated osteoblasts showed signs of oxidative stress and a high apoptosis rate. The levels of osteoblasts activity markers (bone gamma-carboxyglutamic acid protein and bone alkaline phosphatase) were significantly lower in the Al-treated groups than in the control group. The c-Jun N-terminal kinase (JNK), a major signaling pathway in regulating cell apoptosis, was activated. The phosphorylation state of JNK was significantly increased. The mRNA and protein expression of c-Jun were both significantly upregulated. The pro-apoptotic genes (caspase 3, caspase 9, bax, and factor-related apoptosis ligand) were significantly increased. However, Bcl-2, an anti-apoptotic gene, was significantly decreased. In conclusion, the results of this study indicate that Al induces osteoblast apoptosis by activating the oxidative stress-mediated JNK pathway, which causes cell injuries and reduces the number and function of osteoblasts, thereby inhibiting bone formation.
