[PMID: 36675029 PMCID: PMC9861131 DOI: 10.3390/ijms24021518] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Revised: 01/04/2023] [Accepted: 01/09/2023] [Indexed: 01/15/2023] Open
Abstract
Osteoprotegerin (OPG) is a new member of the tumor necrosis factor (TNF) receptor superfamily, which can inhibit the differentiation and activity of osteoclasts by binding to nuclear factor kappa B receptor activator (RANK) competitively with nuclear factor kappa B receptor activator ligand (RANKL). The previous experiments found that OPG can induce apoptosis of mature osteoclasts in vitro, which can inhibit the activity of mature osteoclasts, thereby exerting its role in protecting bone tissue. In addition, pyroptosis is a new type of cell death that is different from apoptosis. It is unclear whether OPG can induce mature osteoclast pyroptosis and thereby play its role in protecting bone tissue. In this study, the results showed that compared with the control group, the survival rate of osteoclasts in the OPG group was significantly reduced, and the contents of IL-1β, IL-18, and LDH in the supernatant both increased. Many osteoclast plasma membranes were observed to rupture in bright fields, and OPG induced loss of their morphology. Flow cytometry was used to analyze the pyroptosis rate; OPG significantly increased the osteoclast pyroptosis rate. To further reveal the mechanism of OPG-induced osteoclast pyroptosis, we examined the expression level of pyroptosis-related genes and proteins, and the results found that OPG increased the expression of NLRP3, ASC, caspase-1, and GSDMD-N compared with the control group. In summary, OPG can induce osteoclast pyroptosis, and its mechanism is related to the expression levels of ASC, NLRP3, caspase 1 and GSDMD, which were included in the classical pathway of pyroptosis.

Abstract
Various factors cause animal bone malnutrition disease during intensive culture. Osteoclasts play an important role in regulating bone metabolism disease. Osteoprotegerin (OPG) modulates osteoclast function; however, the mechanism underlying this effect is unknown. Therefore, the present study aimed to explore whether OPG affects duck embryo osteoclast function via purinergic receptor P2X7. OPG significantly inhibited duck embryo osteoclast differentiation and bone resorption, and suppressed F-actin formation. In addition, OPG remarkably impaired duck embryo osteoclasts' adhesive structure. After OPG treatment, the expression of P2X7R significantly reduced, the ATP level and Ca2+-ATPase activity decreased rapidly, and concomitantly suppressed calcium and MAPK signaling. A438079 (a selective P2X7R inhibitor) significantly inhibited duck embryo osteoclast differentiation and bone resorption, and the phosphorylation of Ca2+ regulated proteins (CAM, CAMKII, CAMKIV) and MAPKs (ERK, JNK, and P38) were markedly suppressed. Pretreatment of duck embryo osteoclasts with BzATP, a P2X7R agonist, activated Ca2+ and MAPK signaling. BzATP alleviated OPG-induced duck embryo osteoclast differentiation and adhesive structure damage, and recovered the distribution of adhesion-related proteins in mature duck embryo osteoclasts. Thus, P2RX7-mediated Ca2+ and MAPK signaling has a key function in OPG-induced duck embryo osteoclast differentiation and adhesive structure damage. P2X7R might be an ideal target to treat bone diseases through regulating bone cell activation.

Abstract
Normal development and growth of bones are critical for poultry. With the rapid growth experienced by broiler chickens, higher incidences of leg weakness and lameness are common problems in adolescent meat-type poultry that present huge economic and welfare issues. Leg disorders such as angular bone deformities and tibial dyschondroplasia have become common in broilers and are associated with poor growth, high mortality rates, increased carcass condemnation, and downgrading at slaughter. Probiotics have shown promise for a variety of health purposes, including preventing diarrhea, elevating carcass quality, and promoting growth of the poultry. In addition, recent studies have indicated that probiotics can maintain the homeostasis of the gut microbiota and improve the health of the gastrointestinal tract, which confers a potentially beneficial effect on bone health. This review mainly describes the occurrence of broiler leg disease and the role of probiotics in bone health through regulating the gut microbiota and improving intestinal function, thus providing a relevant theoretical basis for probiotics to hinder the development of skeletal disorders in broiler chickens.

Abstract
Osteoclastogenesis is induced by receptor activator of nuclear factor-κB ligand (RANKL) and macrophage colony-stimulating factor (M-CSF), and can be suppressed by osteoprotegerin (OPG). Beclin1 has a dual role in osteoclastogenesis. However, the role of Beclin1-mediated autophagy during OPG-induced inhibition of osteoclastogenesis remains unclear. Here, we found that Beclin1 and matrix metalloproteinase 9 (MMP-9) expression were increased during osteoclastogenesis. OPG (20, 40, and 80 ng/mL) decreased Src and MMP-9 expression, but augmented Beclin1 expression and fluorescence intensity. Similarly, treatment with the autophagy activator rapamycin increased Beclin1 expression during OPG-induced inhibition of osteoclastogenesis. Further, Beclin1 knockdown restored osteoclast numbers by reducing autophagy during OPG-induced inhibition of osteoclastogenesis. These results indicate that Beclin1 has a positive role during OPG-induced inhibition of osteoclastogenesis by regulating autophagy, which might provide a potential basis for osteoclastogenesis.

Abstract
Co-culture models have become mandatory for obtaining better insights into bone homeostasis, which relies on the balance between osteoblasts and osteoclasts. Cigarette smoking (CS) has been proven to increase the risk of osteoporosis; however, there is currently no proven treatment for osteoporosis in smokers excluding cessation. Bisphosphonates (BPs) are classical anti-osteoclastic drugs that are commonly used in examining the suitability of bone co-culture systems in vitro as well as to verify the response to osteoporotic stimuli. In the present study, we tested the effects of BPs on cigarette smoke extract (CSE)-affected cells in the co-culture of osteoblasts and osteoclasts. Our results showed that BPs were able to reduce CSE-induced osteoporotic alterations in the co-culture of osteoblasts and osteoclasts such as decreased matrix remodeling, enhanced osteoclast activation, and an up-regulated receptor activator of nuclear factor (NF)-kB-ligand (RANKL)/osteoprotegerin (OPG) ratio. In summary, BPs may be an effective alternative therapy for reversing osteoporotic alterations in smokers, and the potential mechanism is through modulation of the RANKL/OPG ratio.

Abstract
Objectives Osteoclasts (OC) are unique terminally differentiated cells whose primary function is bone resorption. We previously showed that osteoprotegerin (OPG) inhibits OC differentiation in vitro by enhancing autophagy via the adenosine monophosphate‐activated protein kinase (AMPK)/mTOR/p70S6K signalling pathway in vitro. Here, we aimed to elucidate the mechanism of AMPK mediated autophagy to regulate OPG‐mediated inhibition of OC differentiation and identify potential therapeutic targets associated with bone loss. Materials and Methods We used the AMPK activator AICAR to determine the relationship between AMPK activation and OC differentiation, and studied the role of AMPK‐mediated autophagy in OPG‐mediated inhibition of OC differentiation by using autophagy inhibitors or AMPK knockdown. Results AMP‐activated protein kinase activation caused LC3II accumulation and weakened OC differentiation activity. In contrast, inactivation of autophagy by 3‐methyladenine or Bafilomycin A1 could attenuate OPG‐mediated inhibition of OC differentiation via the AMPK/mTOR/p70S6K signalling pathway. Furthermore, the AMPK inhibitor compound C and knockdown of AMPK impaired OPG‐mediated inhibition of OC differentiation by inducing autophagy. Conclusions These results demonstrated that the AMPK signalling pathway functions as a critical regulator in the OPG‐mediated inhibition of OC differentiation, by inducing autophagy. Our results provide a basis for future bone‐related studies on the AMPK signalling pathway.

Abstract
Avian bone metabolism diseases affect the development and production of chickens, and many of these diseases can be prevented and controlled by balanced nutrition and hormone medicine. The steroid hormone 1α,25-dihydroxyvitamin D3 plays a key role in maintaining the balance of avian bone metabolism. Clinically, 1α,25-(OH)2D3 has been used to treat several bone diseases. Although several previous studies have investigated the effects of 1α,25-(OH)2D3 on osteoclastogenesis, the mechanisms underpinning osteoclast (OC) activity remain largely unknown. Herein, we used molecular and cell biology approaches to demonstrate that 1α,25-(OH)2D3 increases avian OC formation and activity, and upregulates bone resorption-related genes. Moreover, 1α,25-(OH)2D3 regulates the OC cytoskeleton by increasing the formation of zipper-like structure in OC precursor cells to potentiate OC activity via the Src/Rac1 signaling pathway. These findings provide new insight into the role of 1α,25-(OH)2D3 in OC activity.

Abstract
Macrophages, a type of immune cell, are the precursors of osteoclasts, and have important roles in bone remodeling and the immune system. In the present study, the RAW264.7 cell line was used as a macrophage model in order to study the macrophage changes during osteoclastogenesis. Receptor activator of nuclear factor κB ligand (RANKL) and macrophage colony‑stimulating factor (M‑CSF) induce the formation of osteoclasts from several precursor cells. Observation of RAW264.7 macrophage osteoclastogenesis under the induction of RANKL and M‑CSF revealed that except the few RAW264.7 macrophages that were differentiated into osteoclasts, almost all undifferentiated RAW264.7 macrophages underwent apoptosis. BRL‑3A cells have no differentiation ability, and RANKL and M‑CSF treatments did not induce BRL‑3A cell apoptosis. When osteoprotegerin (OPG) was used to completely inhibit the differentiation of RAW264.7 macrophages to osteoclasts, apoptosis did not occur amongst the RAW264.7 macrophages despite the action of RANKL and M‑CSF. Rac1, RhoA and RhoV are apoptosis‑associated genes in the Rho guanosine triphosphate (GTP)ase family. Their expression levels were detected using quantitative polymerase chain reaction (qPCR). During the process of osteoclast differentiation, the mRNA expression of RhoV was significantly upregulated, while apoptosis occurred in a large proportion of macrophages. However, when macrophage apoptosis was inhibited by OPG, RhoV expression was significantly downregulated. Conversely, Rac1 and RhoA expression did not vary in correspondence with the apoptotic rate of the RAW264.7 macrophages. In conclusion, differentiation of RAW264.7 macrophages into osteoclasts resulted in their apoptosis. OPG inhibited RAW264.7 macrophage differentiation into osteoclasts, and thereby inhibited the apoptosis of RAW264.7 macrophages. RhoV mediated the apoptosis of RAW264.7 macrophages during osteoclast differentiation.
