Postmenopausal osteoporosis is a global health problem characterized by decreased in bone mineral density (BMD) and progressive deterioration of microarchitecture and subsequent increase in bone fragility and susceptibility to fracture.  More than 200 million people suffer from osteoporosis worldwide  with about 8.9 million fractures and the prevalence rate of osteoporosis is expected to increase significantly in the future because of increased in life expectancy and aging population. Milk-derived bioactive peptides from cow, goat, sheep, buffalo, and camel exhibit several potential health promoting effect including antiosteoporosis, antihypertensive, antioxidative, antithrombotic, immunomodulatory and anti-inflammatory effects. Epidemiological and intervention studies have shown that milk and milk-derived peptides prevented bone loss in pre- and postmenopausal women. Moreover, quite a lot of studies have reported that milk-derived bioactive peptides can induce osteoblast cell proliferation, differentiation and also prevented bone loss in osteoporotic rats model. Thus, milk-derived peptides exhibits beneficial effect against bone-related diseases and can be of particular interest towards prevention and management of postmenopausal osteoporosis. Hence, the present review summarizes various studies using ISI, SCOPUS and PubMed indexed journals to elucidate the potential role of milk-derived bioactive peptides with in vitro and in vivo antiosteoporotic property

Abstract Objectives Postmenopausal osteoporosis, a condition of low bone density consequent to decreased estrogen levels after menopause in women, is generally treated with hormone replacement therapy. However, long-term hormone use may cause critical side effects including breast cancer. Alternatively, phytoestrogens, which have similar structures to steroid hormones, are reported to cure postmenopausal symptoms with fewer side effects. Here, we investigated the effects of EtOH extract of Circaea mollis Siebold & Zucc. (EECM), a traditional herbal medicine in Asia that exhibits anti-arthritic activities, on postmenopausal osteoporosis. Methods In vitro model: MCF7 breast cancer cells and MC3T3-E1 pre-osteoblast cells were utilized to estimate estrogenic and osteogenic activity. Osteoblastic markers were measured by western blot and real-time PCR. In vivo model: Female mature C57BL/6 mice were ovariectomized and oral administrated with 10 mg/kg and 40 mg/kg of EECM respectively. Results EECM increased alkaline phosphatase activity and osteoblastic markers including osteoprotegerin at day 6 during mouse preosteoblast differentiation. EECM inhibited osteoclast differentiation and bone resorption in an osteoblast-osteoclast primary co-culture system via osteoprotegerin-mediated RANK/RANKL signaling. In ovariectomized mice, EECM prevented bone mineral density decrease and recovered osteoblastic molecules. Conclusions EECM enhanced the differentiation of osteoblasts via osteogenic markers and modulated RANK/RANKL signaling via an elevation of OPG from osteoblasts in vitro and in vivo. Therefore, EECM may be effective in preventing bone loss and offers a promising alternative for the nutritional management of postmenopausal osteoporosis.

Osteoporosis is characterized by a decrease in bone microarchitecture with an increased risk of fracture. Long-term use of primary treatments, such as bisphosphonates and selective estrogen receptor modulators, results in various side effects. Therefore, it is necessary to develop alternative therapeutics derived from natural products. Crataegus pinnatifida Bunge (CPB) is a dried fruit used to treat diet-induced indigestion, loss of appetite, and diarrhea. However, research into the effects of CPB on osteoclast differentiation and osteoporosis is still limited. In vitro experiments were conducted to examine the effects of CPB on RANKL-induced osteoclast differentiation in RAW 264.7 cells. Moreover, we investigated the effects of CPB on bone loss in the femoral head in an ovariectomized rat model using microcomputed tomography. In vitro, tartrate-resistant acid phosphatase (TRAP) staining results showed the number of TRAP-positive cells, and TRAP activity significantly decreased following CPB treatment. CPB also significantly decreased pit formation. Furthermore, CPB inhibited osteoclast differentiation by suppressing NFATc1, and c-Fos expression. Moreover, CPB treatment inhibited osteoclast-related genes, such as Nfatc1, Ca2, Acp5, mmp9, CtsK, Oscar, and Atp6v0d2. In vivo, bone mineral density and structure model index were improved by administration of CPB. In conclusion, CPB prevented osteoclast differentiation in vitro and prevented bone loss in vivo. Therefore, CPB could be a potential alternative medicine for bone diseases, such as osteoporosis.

Abstract Background and aims: Erythropoietin (EPO) is a pleiotropic cytokine, which besides its classical role in driving erythropoiesis, displays tissue protective and immunomodulatory activities. EPO also induces bone loss. While hematopoiesis is mediated via the homodimeric EPO receptor (EPOR), tissue protection is conferred via a heteromer composed of EPOR and CD131. Cibinetide (CIB), a non-erythropoietic analogue of EPO, specifically binds to the heteromeric receptor and confers tissue protection. Our published findings that EPO stimulates osteoclast precursors and entrains a decrease in bone density, raise questions regarding the underlying molecular mechanisms. Here, we evaluated the role of the heteromeric complex in bone metabolism using CIB alone and in combination with EPO in vivo and in vitro. Results: CIB injections to 12-week-old female mice (120 µg/kg thrice weekly for 4 weeks) resulted in a significant increase in tissue mineral density in cortical bone by 5.8% (1416.4±39.27 vs 1338.74±16.56 mgHA/cm 3) and in trabecular bone by 5.2% (1056.52±30.94 vs 1004.13±16.91 mg HA/cm 3) (n=10 in each group, p< 0.05 versus saline-injected controls), as measured by microCT (Figure 1A). To evaluate the capacity of CIB to attenuate EPO mediated bone loss, we administered CIB (300 µg/kg) for 5 consecutive days, to 13-week-old female mice that also received 2 injections of 120U EPO on days 1 and 4. Flow cytometry analysis revealed a 1.8-fold reduction in the number of osteoclast progenitors, defined as Lin -CD11b −CD115 +Ly6C hi, in the EPO + CIB injected mice, compared to the mice injected with EPO alone (n=7 in each group, p< 0.05). Hemoglobin levels and TER119 + bone marrow (BM) erythroid progenitors were similar in both groups. In vitro, EPO administration to BM-derived macrophages (BMDM) enhanced osteoclastogenesis, whereas CIB had an opposite, dose-dependent effect. Combining CIB with EPO inhibited osteoclastogenesis in BMDM, suggesting that CIB overrides the pro-osteoclastogenic effect of EPO (Figure 1B). Conclusions: Our findings highlight the increasing complexity of EPOR signaling in bone and pave the way for clinical translation through potential combination therapy of EPO and CIB in anemic and in cancer patients. Adjunctive administration of CIB may prevent or attenuate bone loss while preserving the erythropoietic actions of EPO.

The two erythropoietin (EPO) receptor forms mediate different cellular responses to erythropoietin. While hematopoiesis is mediated via the homodimeric EPO receptor (EPOR), tissue protection is conferred via a heteromer composed of EPOR and CD131. In the skeletal system, EPO stimulates osteoclast precursors and induces bone loss. However, the underlying molecular mechanisms are still elusive. Here, we evaluated the role of the heteromeric complex in bone metabolism in vivo and in vitro by using Cibinetide (CIB), a non-erythropoietic EPO analogue that exclusively binds the heteromeric receptor. CIB is administered either alone or in combination with EPO. One month of CIB treatment significantly increased the cortical (~5.8%) and trabecular (~5.2%) bone mineral density in C57BL/6J WT female mice. Similarly, administration of CIB for five consecutive days to female mice that concurrently received EPO on days one and four, reduced the number of osteoclast progenitors, defined by flow cytometry as Lin−CD11b−Ly6Chi CD115+, by 42.8% compared to treatment with EPO alone. In addition, CIB alone or in combination with EPO inhibited osteoclastogenesis in vitro. Our findings introduce CIB either as a stand-alone treatment, or in combination with EPO, as an appealing candidate for the treatment of the bone loss that accompanies EPO treatment.

Abstract Context Although metabolic profiles appear to play an important role in menopausal bone loss, the functional mechanisms by which metabolites influence bone mineral density (BMD) during menopause are largely unknown. Objective We aimed to systematically identify metabolites associated with BMD variation and their potential functional mechanisms in peri-/post-menopausal women. Design and Methods We performed serum metabolomic profiling and whole-genome sequencing for 517 perimenopausal (16%) and early postmenopausal (84%) women aged 41 to 64 years in this cross-sectional study. Partial least squares (PLS) regression and general linear regression analysis were applied to identify BMD-associated metabolites, and weighted gene co-expression network analysis was performed to construct co-functional metabolite modules. Furthermore, we performed Mendelian randomization analysis to identify causal relationships between BMD-associated metabolites and BMD variation. Finally, we explored the effects of a novel prominent BMD-associated metabolite on bone metabolism through both in vivo/in vitro experiments. Results Twenty metabolites and a co-functional metabolite module (consisting of fatty acids) were significantly associated with BMD variation. We found dodecanoic acid (DA), within the identified module, causally decreased total hip BMD. Subsequently, the in vivo experiments might support that dietary supplementation with DA could promote bone loss, as well as increase the osteoblast and osteoclast numbers in normal/ovariectomized mice. DA treatment differentially promoted osteoblast and osteoclast differentiation, especially for osteoclast differentiation at higher concentrations in vitro (e.g.,10, 100μM). Conclusions This study sheds light on metabolomic profiles associated with postmenopausal osteoporosis risk, highlighting the potential importance of fatty acids, as exemplified by DA, in regulating BMD.

Antrodia camphoratahas previously demonstrated the efficacy in treating cancer and anti-inflammation. In this study, we are the first to evaluateAntrodia camphorataalcohol extract (ACAE) for osteoporosis recoveryin vitrowith preosteoblast cells (MC3T3-E1) andin vivowith an osteoporosis mouse model established in our previous studies, ovariectomized senescence accelerated mice (OVX-SAMP8). Our results demonstrated that ACAE treatment was slightly cytotoxic to preosteoblast at 25 μg/mL, by which the osteogenic gene expression (RUNX2, OPN, and OCN) was significantly upregulated with an increased ratio of OPG to RANKL, indicating maintenance of the bone matrix through inhibition of osteoclastic pathway. Additionally, evaluation by Alizarin Red S staining showed increased mineralization in ACAE-treated preosteoblasts. Forin vivostudy, our results indicated that ACAE inhibits bone loss and significantly increases percentage bone volume, trabecular bone number, and bone mineral density in OVX-SAMP8 mice treated with ACAE. Collectively,in vitroandin vivoresults showed that ACAE could promote osteogenesis and prevent bone loss and should be considered an evidence-based complementary and alternative medicine for osteoporosis therapy through the maintenance of bone health.

IL-20 is a proinflammatory cytokine of the IL-10 family that is involved in psoriasis, rheumatoid arthritis, atherosclerosis, and stroke. However, little is known about the role of IL-20 in bone destruction. We explored the function of IL-20 in osteoclastogenesis and the therapeutic potential of anti–IL-20 monoclonal antibody 7E for treating osteoporosis. Higher serum IL-20 levels were detected in patients with osteopenia and osteoporosis and in ovariectomized (OVX) mice. IL-20 mediates osteoclastogenesis by up-regulating the receptor activator of NF-κB (RANK) expression in osteoclast precursor cells and RANK ligand (RANKL) in osteoblasts. 7E treatment completely inhibited osteoclast differentiation induced by macrophage colony-stimulating factor (M-CSF) and RANKL in vitro and protected mice from OVX-induced bone loss in vivo. Furthermore, IL-20R1–deficient mice had significantly higher bone mineral density (BMD) than did wild-type controls. IL-20R1 deficiency also abolished IL-20–induced osteoclastogenesis and increased BMD in OVX mice. We have identified a pivotal role of IL-20 in osteoclast differentiation, and we conclude that anti–IL-20 monoclonal antibody is a potential therapeutic for protecting against osteoporotic bone loss.

Postmenopausal osteoporosis (PMOP) is a type of bone metabolism disease-related to estrogen deficiency with an increasing incidence. Traditional Chinese (TCM) has always been used and showed effectiveness in treating PMOP. In the current study, Bu-Yang herbs were considered to be the most frequently used and efficient TCM herbs in PMOP treatment. However, chemical and pharmacological profiles were not elucidated. Network pharmacology was conducted on representative Bu-Yang herbs (Yin-Yang-Huo. Du-Zhong, Bu-Gu-Zhi, Tu-Si-Zi) to investigate the mechanism of Bu-Yang herbs on PMOP. Chemical compounds, potential targets, and disease related genes were available from the corresponding database. Results showed that Bu-Yang herbs could interact with ESR1 and estrogen signaling pathways. For further validation, the Bu-Yang decoction (BYD), formula consisted of the above-mentioned 4 Bu-Yang herbs was presented for experimental validation. In vivo, BYD significantly reversed ovariectomy (OVX)-induced osteoporosis progress in a dose-dependent manner by up-regulation of bone mineral density and amelioration of bone microarchitecture. In vitro, BYD dramatically improved the proliferation and mineral nodules formation of osteoblasts. Both in vitro and in vivo results illustrated that the phenotype change induced by BYD is correlated with up-regulated of ESR1 and activation of the β-catenin pathway. Meanwhile, inhibition of ESR1 by ICI182, 780 blocked the osteogenic phenotype and β-catenin pathway activation induced by BYD. In conclusion, the current study suggested that Bu-Yang herbs are the most useful TCM herbs in treating PMOP. Furthermore, the integrated strategy of network pharmacology prediction with experimental validation suggested that BYD exerted its anti-PMOP via ESR1 and the downstream mechanism might be activation of the β-catenin signaling pathway.

The aim of this study was to evaluate the effects of root bark of Eleutherococcus sessiliflorus (ES) on osteoclast differentiation and function in vitro and in vivo. In vitro, we found that ES significantly inhibited the RANKL-induced formation of TRAP-positive multinucleated osteoclasts and osteoclastic bone resorption without cytotoxic effects. ES markedly downregulated the expression of nuclear factor of activated T cells cytoplasmic 1 (NFATc1); c-Fos; and osteoclast-related marker genes, such as TRAP, osteoclast-associated receptor (OSCAR), matrix metalloproteinase-9 (MMP-9), calcitonin receptor, cathepsin K, the 38 kDa d2 subunit of the vacuolar H+-transporting lysosomal ATPase (Atp6v0d2), dendritic cell-specific transmembrane protein (DC-STAMP), and osteoclast-stimulatory transmembrane protein (OC-STAMP). These effects were achieved by inhibiting the RANKL-mediated activation of MAPK signaling pathway proteins, including p38, ERK, and JNK. In vivo, ES attenuated OVX-induced decrease in bone volume to tissue volume ratio (BV/TV), trabecular thickness (Tb.Th), trabecular number (Tb.N), and bone mineral density, but increased trabecular separation (Tb.Sp) in the femur. Collectively, our findings showed that ES inhibited RANKL-activated osteoclast differentiation in bone marrow macrophages and prevented OVX-mediated bone loss in rats. These findings suggest that ES has the potential to be used as a therapeutic agent for bone-related diseases, such as osteoporosis.
