In traditional oriental medicines, Commiphora myrrha and its resinous exudate (i.e., myrrh) are used as herbal remedies to treat various inflammatory and metabolic disorders. Until now, C. myrrha-derived herbal products are considered useful source for bioactive compounds to manage numerous human diseases. This study investigated the effects of water extract of C. myrrha resin (WCM) and its polysaccharide (WCM-PE) on modulatory effects of osteoclast differentiation and/or ovariectomized-induced bone loss. Oral administration of WCM (200 and 500 mg/kg/day for four weeks) notably decreased trabecular bone loss and lipid accumulation in the bone marrow cavity. WCM and WCM-PE dose-dependently inhibited receptor activator of nuclear factor-κB ligand (RANKL)-induced osteoclastogenesis and suppressed RANKL-mediated overexpression of c-Fos and nuclear factor of activated T cells, cytoplasmic 1, thereby downregulating osteoclast-specific gene (Atp6v0d2, DC-STAMP and cathepsin K) expression. Thus, our results suggest that WCM and WCM-PE are promising nutraceutical candidates for the management of osteoporosis in postmenopausal women.

Estrogen deficiency in postmenopausal women causes homeostatic imbalance of bone, resulting in bone loss and osteoporosis. Agastache rugosa, a plant belonging to the Lamiaceae family, is an aromatic herb, and the leaves of this herb are widely used as food ingredients. Extracts of A. rugosa have various bioactivities including anti-HIV integration, anti-inflammatory, and anti-atherogenic properties. However, the beneficial effect of A. rugosa on bone has not been studied. Therefore, we investigated the effects of water extract of A. rugosa (WEAR) on osteoclast differentiation and estrogen deficiency-induced bone loss in ovariectomized (OVX) mice as an animal model for postmenopausal osteoporosis. The oral administration of WEAR remarkably improved OVX-induced trabecular bone loss and fat accumulation in the bone marrow. WEAR suppressed receptor activator of nuclear factor-κB ligand (RANKL)-induced osteoclast differentiation in osteoclast precursor cells, subsequently inhibiting resorption activity on a bone mimetic surface. WEAR inhibited the expression of cellular oncogene fos (c-Fos) and nuclear factor of activated T-cells cytoplasmic 1 (NFATc1), key osteoclastogenic transcription factors, by decreasing RANKL-induced activation of mitogen-activated protein kinases (MAPKs), and nuclear factor-κB (NF-κB) pathways. We also identified seventeen phytochemicals present in WEAR, including five phenols and twelve flavonoids, and found eleven bioactive constituents that have anti-osteoclastogenic effects. Collectively, these results suggest that WEAR could be used to treat and prevent postmenopausal osteoporosis by suppressing osteoclastogenesis.

Mentha arvensis L., is an aromatic herb that belongs to the Lamiaceae family and is widely used in medicinal applications, essential oil applications, and food flavoring. The extract of M. arvensis has been reported to exert sedative-hypnotic, anti-inflammatory, anti-fungal, and anti-bacterial effects. However, its effects on bone metabolism have not yet been studied. Here, we investigated the effects of the water extract of M. arvensis (WEMA) on osteoclast formation in vitro and bone loss in an ovariectomized mouse model. We found that WEMA inhibited osteoclast differentiation by directly acting on osteoclast precursor cells. WEMA inhibited receptor activator of nuclear factor-κB ligand (RANKL)-induced the expression of cellular oncogene fos (c-Fos) and nuclear factor of activated T cells c1 (NFATc1), crucial transcription factors for osteoclast differentiation, by suppressing RANKL-induced activation of early signaling pathways such as those of mitogen-activated protein kinases (MAPKs) and nuclear factor-κB (NF-κB). In addition, oral administration of WEMA suppressed ovariectomy-induced trabecular bone loss in mice. We additionally identified phytochemicals in WEMA that are known to have anti-osteoclastogenic or anti-osteoporotic properties. Collectively, these results suggest that WEMA is a promising herbal candidate that can be used to prevent or treat postmenopausal osteoporosis.

Forsythia Suspensa

In traditional oriental medicine, the fruit of Forsythia suspensa has been used as a nutritional supplement to alleviate inflammation and treat gastrointestinal diseases. However, there is no information available on its beneficial effects on bone. We investigated the beneficial effects of F. suspensa water extract (WFS) on osteoclast differentiation and bone loss. The microarchitecture of trabecular bone was analyzed by micro-computed tomography. Osteoclast differentiation was evaluated based on tartrate-resistant alkaline phosphatase activity, and bone resorption activity was examined on a bone-like mineral surface. The mechanism of action of WFS was assessed by evaluating the expression and activation of signaling molecules. Phytochemical constituents were identified and quantitated by ultrahigh-performance liquid chromatography–tandem mass spectrometry. WFS reduced ovariectomy-induced trabecular bone loss and inhibited receptor activator of nuclear factor-κB ligand (RANKL)-induced osteoclast formation and resorption activity. WFS suppressed RANKL-induced expression of nuclear factor of activated T cells cytoplasmic 1, a crucial transcription factor for osteoclast differentiation by decreasing c-Fos protein levels and suppressing the activation of p38 and c-Jun-N-terminal kinase. We also identified 12 phytochemicals in WFS including lignans, phenylethanoids, and flavonoids. Collectively, these results suggest that WFS inhibits osteoclast differentiation and can potentially be used to treat postmenopausal osteoporosis.

Bone homeostasis is maintained by the synergistic actions of bone-resorbing osteoclasts and bone-forming osteoblasts. Here, we show that the transcriptional coactivator/repressor interferon-related developmental regulator 1 (Ifrd1) is expressed in osteoclast lineages and represents a component of the machinery that regulates bone homeostasis. Ifrd1 expression was transcriptionally regulated in preosteoclasts by receptor activator of nuclear factor κB (NF-κB) ligand (RANKL) through activator protein 1. Global deletion of murineIfrd1increased bone formation and decreased bone resorption, leading to a higher bone mass. Deletion ofIfrd1in osteoclast precursors prevented RANKL-induced bone loss, although no bone loss was observed under normal physiological conditions. RANKL-dependent osteoclastogenesis was impairedin vitroinIfrd1-deleted bone marrow macrophages (BMMs).Ifrd1deficiency increased the acetylation of p65 at residues K122 and K123 via the inhibition of histone deacetylase-dependent deacetylation in BMMs. This repressed the NF-κB-dependent transcription of nuclear factor of activated T cells, cytoplasmic 1 (NFATc1), an essential regulator of osteoclastogenesis. These findings suggest that an Ifrd1/NF-κB/NFATc1 axis plays a pivotal role in bone remodelingin vivoand represents a therapeutic target for bone diseases.

Osteoporosis results from imbalance between new bone formation and bone resorption leading to bone loss and is especially troublesome for postmenopausal women who suffer from estrogen deficiency. The ability of new therapeutic agents to treat this bone disease with minimal side effects has been extensively reported on and is continuously being sought out by researchers in this field. Thus, the purpose of this study was to investigate a natural herb that was already being used as a new treatment for osteoporosis. Here we found that water extract of Glycyrrhizae radix (GR) inhibits receptor activator of nuclear factor-[Formula: see text]B ligand (RANKL)-induced osteoclast differentiation in a dose-dependent manner without causing cytotoxicity. The mRNA expression of c-Fos, nuclear factor of activated T cells cytoplasmic 1 (NFATc1), tartrate-resistant acid phosphatase (TRAP), and osteoclast-associated receptor (OSCAR) was considerably inhibited by GR treatment. GR inhibited RANKL-mediated c-Fos and NFATc1 expression in a dose-dependent manner. GR inhibited the degradation of I-[Formula: see text]B in RANKL-stimulated BMMs. However, GR-mediated inhibition of osteoclast differentiation and osteoclast-specific gene expression, including NFATc1, was reversed by ectopic expression of c-Fos. Also, GR significantly inhibited osteoclast formation in mouse calvariae in the presence of IL-1 and prostaglandin E2 (PGE2). Taken together, these results suggest that GR inhibited osteoclast differentiation, raising the possibility that GR may serve as a useful drug for osteoporosis.

The rhizome ofDryopteris crassirhizomahas been used as a traditional herbal medicine for treating various inflammatory and infectious diseases such as tapeworm infestation and mumps. In the present study, we investigated the bone protective effect of water extract of the rhizome ofDryopteris crassirhizoma(WEDC). We found that WEDC inhibits osteoclast differentiation via directly acting on osteoclast precursors. In osteoclast precursors, WEDC inhibited receptor activator of nuclear factor-κB ligand- (RANKL-) induced expression of c-Fos and nuclear factor of activated T cells cytoplasmic 1, a key downstream target of c-Fos during osteoclast differentiation. We found that WEDC inhibits RNAKL-induced activation of extracellular-regulated kinase and NF-κB that mediates c-Fos expression and osteoclast differentiation. In addition to the inhibitory effect of osteoclast differentiation, WEDC markedly suppressed bon-resorbing activity of mature osteoclasts, which was accompanied by disruption of actin ring structure. Furthermore, administration of WEDC suppressed RANKL-induced trabecular bone loss in mice. Collectively, our results demonstrate that WEDC inhibits not only osteoclast differentiation by inhibiting RANK signaling pathways in osteoclast precursors but also bone resorption by disrupting actin ring in mature osteoclasts, thereby contributing to its protective effect on bone loss.

Persimmon (Diospyros kaki L.f.) leaves have traditionally been used as a phytomedicine, in health beverages to treat cardiovascular and respiratory disease and to promote maternal health in East Asia. In particular, polysaccharides from persimmon are known to have anti-coagulant, anti-oxidant, and immune-stimulatory activities. However, their beneficial effects against osteoporosis have not been reported. In the present study, we investigated the anti-osteoporotic effects of polysaccharides from persimmon leaves (PLE0) using an in vivo model of ovariectomy (OVX)-induced bone loss and an in vitro system of receptor activator of nuclear factor-κB ligand (RANKL)-induced osteoclast differentiation. In the OVX mouse model, PLE0 remarkably improved OVX-induced trabecular bone loss by suppressing osteoclast activity. In primary bone marrow-derived macrophages (BMMs), PLE0 dose-dependently inhibited osteoclast differentiation. In addition, PLE0 down-regulated RANKL-induced activation of mitogen-activated protein kinases (MAPKs) such as p38, ERK, and JNK resulting in suppression of nuclear factor of activated T cells cytoplasmic 1 (NFATc1) expression. Our results indicate that PLE0 has anti-osteoporotic effects in OVX-induced bone loss via inhibition of osteoclast differentiation. Taken together, PLE0 from persimmon may prevent postmenopausal bone loss and osteoporotic bone fragility.

The supplementation of royal jelly (RJ) is known to provide a variety of health benefits, including anti-inflammatory and anti-obesity effects. RJ treatment also reportedly protects against bone loss, but no single factor in RJ has yet been identified as an anti-osteoporosis agent. Here we fractionated RJ and identified 10-hydroxy-2-decenoic acid (10H2DA) as a key component involved in inhibiting osteoclastogenesis based on mass spectrometric analysis. We further demonstrated free fatty acid receptor 4 (FFAR4) as directly interacting with 10H2DA; binding of 10H2DA to FFAR4 on osteoclasts inhibited receptor activator of nuclear factor-κB (NF-κB) ligand (RANKL)-induced activation of NF-κB signaling, thereby attenuating the induction of nuclear factor of activated T cells (NFAT) c1, a key transcription factor for osteoclastogenesis. Oral administration of 10H2DA attenuated bone resorption in ovariectomized mice. These results suggest a potential therapeutic approach of targeting osteoclast differentiation by the supplementation of RJ, and specifically 10H2DA, in cases of pathological bone loss such as occur in postmenopausal osteoporosis.

The herb Orostachys japonicus has been traditionally used to treat chronic diseases, such as hepatitis, hemorrhoids, and cancer, in Asia. In this study, we investigated the effect of Orostachys japonicus water extract (OJWE) on the receptor activator of nuclear factor-κB ligand (RANKL)-induced osteoclast differentiation and bone loss. We found that OJWE inhibited RANKL-induced osteoclast differentiation in a dose-dependent manner without affecting bone resorption in bone marrow-derived macrophage cells. Interestingly, OJWE significantly reduced serum levels of C-terminal telopeptide of type 1 collagen and tartrate-resistant acid phosphatase (TRAP) 5b, markers of bone resorption and osteoclast number, respectively, in an animal model of bone loss. Furthermore, OJWE suppressed the RANKL-induced up-regulation of nuclear factor of activated T cells cytoplasmic 1 (NFATc1) expression, and activation of the p38 signaling pathway, but prevented the RANKL-mediated down-regulation of interferon regulatory factor-8 (IRF-8), which is known to be an anti-osteoclastogenic factor that represses NFATc1 expression. We also identified gallic acid and quercetin-3-O-β-D-glucoside as the OJWE components that inhibit RANKL-induced osteoclast differentiation. These results suggest that OJWE inhibits osteoclast differentiation by inhibiting RANKL-induced NFATc1 expression, which prevents osteoclast differentiation and bone loss. The present study elucidated a mechanism of action underlying the inhibitory effect of OJWE on osteoclast differentiation. Our findings suggest that O. japonicus has therapeutic potential for use in the treatment of bone diseases.
