Garcinol suppresses RANKL-induced osteoclastogenesis and its underlying mechanism.

Osteoclasts (OCs) are multinuclear giant cells responsible for bone resorption, and an excessive bone resorption by OCs plays an important role in osteoporosis. Commonly used drugs for the treatment of osteoporosis have severe side effects. As such, identification of alternative treatments is essential. Garcinol, a polyisoprenylated benzophenone extracted from the fruit of Garcinia indica, has shown a strong antitumor effect through the nuclear factor-κB (NF-κB) and mitogen-associated protein kinases (MA...


Deguelin inhibits RANKL-induced osteoclastogenesis in vitro and prevents inflammation-mediated bone loss in vivo.

Excessive bone resorption by osteoclasts (OCs) plays an important role in lytic bone diseases, such as osteoporosis. Although the pharmacological treatment of osteoporosis has been extensively developed, alternative treatments are still needed. Deguelin, a rotenoid isolated from several plant species, is a strong antitumor agent; however, its effect on OCs remains unclear. To the best of our knowledge, this is the first study to report that deguelin inhibits the receptor activator of nuclear factor-κB (NF-...

DPP-4 inhibitor impedes lipopolysaccharide-induced osteoclast formation and bone resorption in vivo.

Dipeptidyl peptidase 4 (DPP-4) inhibition is a new therapeutic strategy for type 2 diabetic patients. DPP-4 has been reported to enhance inflammation. However, the effect of DPP-4 inhibition on inflammation remains unknown. Lipopolysaccharide (LPS) is a strong inducer of inflammation and osteoclast formation. In this study, we investigated in vivo effects of DPP-4 inhibition on LPS-induced osteoclast formation and bone resorption, as well as in vitro effects of DPP-4 inhibition on RANKL-induced osteoclastog...


Arctigenin inhibits RANKL-induced osteoclastogenesis and hydroxyapatite resorption in vitro and prevents titanium particle-induced bone loss in vivo.

Wear particle-induced bone resorption leads to prosthesis loosening, which is a major complication associated with total joint arthroplasty. Although the exact mechanism remains unclear, wear particle-induced extensive osteoclastogenesis plays a critical role in this process. Thus, a potential treatment of prosthetic loosening is focused on suppressing extensive osteoclast formation and bone resorption, which prevents wear particle-induced osteolysis. Arctigenin isolated from Arctium lappa has numerous bene...

Neotuberostemonine inhibits osteoclastogenesis via blockade of NF-κB pathway.

Osteoporosis has been attributed to low bone mass arising from cellular communications between bone formation and bone resorption. Osteoclastogenesis is induced by M-CSF and RANKL in hematopoietic lineage cells. Once RANK/RANKL complex is formed, TRAF6 is recruited and triggers the activation of NF-κB pathway and the expression of osteoclast-related genes including NFATc1. Neotuberostemonine (NTS) is an active compound isolated from Stemona tuberosa Lour. Pharmacologically, NTS has been known to possess an...

Platycarya strobilacea leaf extract inhibits tumor necrosis factor-α production and bone loss induced by Porphyromonas gingivalis-derived lipopolysaccharide.

Remodeling of alveolar bone is controlled by osteoclast-mediated bone resorption and osteoblast-induced bone formation. LPS of Porphyromonas gingivalis, a major causative agent of periodontitis, produces proinflammatory cytokines in host immune cells, which thereby triggers osteoclastogenesis and leads to alveolar bone resorption. We investigated the anti-periodontitis potential of Platycarya strobilacea leaf extract (PLE), which is used as a traditional medicine in Asian countries.

Modulating calcium-mediated NFATc1 and mitogen-activated protein kinase deactivation underlies the inhibitory effects of kavain on osteoclastogenesis and bone resorption.

Osteoclasts are responsible for bone resorption during the process of bone remodeling. Increased osteoclast numbers and bone resorption activity are the main factors contributing to bone loss-related diseases such as osteoporosis. Therefore, modulating the formation and function of osteoclasts is critical for the effective treatment of osteolysis and osteoporosis. Kavain is the active ingredient extracted from the root of the kava plant, which possesses known anti-inflammatory properties. However, the effec...

A novel rhein derivative modulates bone formation and resorption and ameliorates oestrogen-dependent bone loss.

Osteoporosis, an osteolytic disease that affects millions of people worldwide, features a bone remodelling imbalance between bone resorption by osteoclasts and bone formation by osteoblasts. Identifying dual target-directed agents that inhibit excessive bone resorption and increase bone formation is considered an efficient strategy for developing new osteoporosis treatments. Rhein, a natural anthraquinone, can be isolated from various Asian herbal medicines. Rhein and its derivatives have been reported to h...

Skullcapflavone II inhibits osteoclastogenesis by regulating reactive oxygen species and attenuates the survival and resorption function of osteoclasts by modulating integrin signaling.

Many bone diseases, such as osteoporosis and rheumatoid arthritis, are attributed to an increase in osteoclast number or activity; therefore, control of osteoclasts has significant clinical implications. This study shows how skullcapflavone II (SFII), a flavonoid with anti-inflammatory activity, regulates osteoclast differentiation, survival, and function. SFII inhibited osteoclastogenesis with decreased activation of MAPKs, Src, and cAMP response element-binding protein (CREB), which have been known to be ...

Bone protection by inhibition of microRNA-182.

Targeting microRNAs recently shows significant therapeutic promise; however, such progress is underdeveloped in treatment of skeletal diseases with osteolysis, such as osteoporosis and rheumatoid arthritis (RA). Here, we identified miR-182 as a key osteoclastogenic regulator in bone homeostasis and diseases. Myeloid-specific deletion of miR-182 protects mice against excessive osteoclastogenesis and bone resorption in disease models of ovariectomy-induced osteoporosis and inflammatory arthritis. Pharmacolog...

Interleukin-37 inhibits osteoclastogenesis and alleviates inflammatory bone destruction.

Excessive osteoclast formation is one of the important pathological features of inflammatory bone destruction. Interleukin-37 (IL-37) is an anti-inflammatory agent that is present throughout the body, but it displays low physiological retention. In our study, high levels of the IL-37 protein were detected in clinical specimens from patients with bone infections. However, the impact of IL-37 on osteoclast formation remains unclear. Next, IL-37 alleviated the inflammatory bone destruction in the mouse in vivo...

The expression profile of genes involved in osteoclastogenesis detected in whole blood of Arabian horses during 3 years of competing at race track.

One of the most significant reason of economic loss on race track performance is lame in performed horses. Primarily, due to the failure within proper bone maintenance during conditioning in young horses. The training overload causes bone turnover disturbances in homeostasis between bone resorption and bone formation which promote the bone loss. Within our study we investigated training induced changes in transcript abundance of genes (NFATc1, CTSK, DAP12, CLEC5A, IL6ST, VAV3) involved in osteoclastogenesis...

Bone Resorption Activity in Mature Osteoclasts.

Bone homeostasis depends on balanced bone deposition and bone resorption, which are mediated by osteoblasts and osteoclasts, respectively. As one therapeutic strategy, the blockage of osteoclast activity reduces subsequent bone erosion. Morphological analysis of bone resorption pits formed by osteoclasts by using scanning electron microscope is an effective method for understanding rheumatoid arthritis. Here we describe methods for observing surface microstructure of pits formed by osteoclasts on hard tissu...

Influence of chronic alcoholism and estrogen deficiency on the immunohistochemical expression of regulatory proteins of the bone resorption process in the periodontium of Wistar rats.

The aim of this study was to investigate possible changes in immunohistochemical expression of proteins regulating the bone resorption process in the periodontium of rats subjected to alcoholism and/or estrogen deficiency. The investigated proteins were receptor activator of nuclear factor-kappa β ligand (RANKL), a protein that stimulates bone resorption, and osteoprotegerin (OPG), a protein that inhibits bone resorption. At the molecular level, decreased OPG expression and/or increased RANKL expression ar...

Transcriptomic Data Identified Key Transcription Factors for Osteoporosis in Caucasian Women.

Osteoporosis is a prevalent bone metabolic disease, mainly caused by excessive bone resorption (by osteoclasts) over bone formation (by osteoblasts). Identifying the key transcription factors and understanding the regulatory network influencing osteoclastogenesis will be helpful to explore the potential biological mechanism for osteoporosis. In our study, peripheral blood monocyte (PBM) was used as a cell model for bone mineral density (BMD) research. PBMs serve as progenitors of osteoclasts and produce imp...

Serum calcium concentration is maintained when bone resorption is suppressed by osteoprotegerin in young growing male rats.

Serum calcium is maintained in a narrow range through regulation of Ca metabolism in the intestine, kidney, and bone. Calcium is incorporated and resorbed from bone during bone remodeling via cellular processes as well as by exchange. Both routes contribute to calcium homeostasis. To assess the magnitude of bone turnover contribution to calcium homeostasis we labeled bone with a Ca tracer and measured Ca release following stimulation or suppression of bone resorption. Young growing male rats (n = 162) w...

Inhibitory effect of vanillin on RANKL-induced osteoclast formation and function through activating mitochondrial-dependent apoptosis signaling pathway.

Bone matrix homeostasis associated diseases such as osteoporosis and erosive arthritis were caused by the imbalance of osteoclast-mediated bone-resorption and osteoblast-mediated bone-formation. Suppressing the fusion and differentiation of osteoclast from osteoclast precursors are an essential way to maintain the dynamic balance of resorption and formation. Recently, some natural products were discovered to inhibit osteoclast formation and function for potential treatment of osteoporosis. Vanillin was prev...

Modification of cysteine 179 in IKKβ by ursolic acid inhibits titanium wear particles-induced inflammation, osteoclastogenesis and hydroxylapatite resorption.

Aseptic loosening of artificial joint mainly accounts for the failure of arthroplasty. We previously reported that ursolic acid inhibited titanium particle-induced osteolysis via suppression of NF-kB signaling. In this study, we demonstrated that the inhibitory effect of UA on Ti particle-induced inflammation and osteoclastogenesis targets on IKKβ cys-179. A retrovirus packaged IKKβC179A plasmid with mutation of Cys-179 replaced by Ala was constructed. RT-PCR, western blot, and Immunofluorescence were per...

High-fat diet disrupts bone remodeling by inducing local and systemic alterations.

A high-fat (HF) diet leads to detrimental effects on alveolar bone (AB); however, the mechanisms linking adiposity to bone loss are poorly understood. This study investigated if AB resorption induced by an HF diet is associated with the regulation of inflammatory gene expression and if adipocytes can directly interfere with osteoclastogenesis. We also evaluated the effects of diet restriction (DR) on bone phenotype. C57BL6/J mice were fed normal chow or an HF diet for 12 weeks. Samples of maxillae, femur, b...

Bergapten suppresses RANKL-induced osteoclastogenesis and ovariectomy-induced osteoporosis via suppression of NF-κB and JNK signaling pathways.

Bergapten (BP), derived from Cnidium monnieri (L.) Cusson, is an ingredient widely used in traditional Chinese medicine and has important biological and pharmacological activities. However, the effect of BP on ovariectomy-induced osteoporosis and the underlying mechanism are not entirely clear. In this study, we investigated the effects of BP on ovariectomy-induced osteoporosis and receptor activator of nuclear factor-κB ligand (RANKL)-induced osteoclastogenesis in vivo and in vitro, and explored the und...

Conditioned fear stress increases bone resorption in apical periodontitislesions in Wistar male rats.

Because the impact of conditioned fear stress on apical bone resorption is unknown, the aim of the current studywas to use a rat model to evaluate the impact of conditioned fear stress on the bone resorption of inflammatory apical periodontitis lesions.

Small molecule inhibitor RepSox prevented ovariectomy-induced osteoporosis by suppressing osteoclast differentiation and bone resorption.

Osteoporosis (OP) is a serious metabolic disease that, due to the increased number or function of osteoclasts, results in increased bone brittleness and, therefore, fragile fracture. Some recent studies report the importance of the transforming growth factor β (TGFβ) pathway in bone homeostasis. RepSox is a small molecule inhibitor of TGFβRI that has a wide range of potential application in clinical medicine, except OP. The aim of our study is to evaluate the effects of RepSox on the differentiation and ...

The naturally derived small compound Osthole inhibits osteoclastogenesis to prevent ovariectomy-induced bone loss in mice.

This study was to determine the bone protective effects and underlying mechanisms of Osthole (OT) in ovariectomized (OVX) mice. We found that the inhibitory effects of OT on receptor activator of nuclear factor kappa-B ligand (RANKL)-activated osteoclastogenesis are responsible for its bone protective effects in OVX mice.

BCL3 regulates RANKL-induced osteoclastogenesis by interacting with TRAF6 in bone marrow-derived macrophages.

Tumor necrosis factor receptor-associated factor 6 (TRAF6) is an essential component of the signaling complex that mediates osteoclastogenesis. As an adaptor protein of E3 ligase function, TRAF6 regulates NF-κB signaling via TAK1 and I-κB kinase (IKK) activation. Here, we investigated novel mechanisms by which TRAF6 signaling is regulated under receptor activator of nuclear factor-κB ligand (RANKL)-induced osteoclastogenesis.

The Novel p38 Inhibitor, Pamapimod, Inhibits Osteoclastogenesis and Counteracts Estrogen-Dependent Bone Loss in Mice.

Pamapimod (PAM) is a novel selective p38 mitogen-activated protein (MAP) kinase inhibitor proved to be effective in rheumatoid arthritis in phase 2 clinical trial. However, its effect on osteoclast-associated osteoporosis and the underlying mechanisms remain unclear. In this study, we showed that PAM suppressed receptor activator of nuclear factor-κB ligand (RANKL)-induced osteoclast formation via inhibition of p38 phosphorylation and subsequent c-Fos and nuclear factor of activated T cells c1 (NFATc1) exp...
