Abstract
Maintenance of mitochondrial homeostasis is crucial for ensuring healthy mitochondria and normal cellular function. This process is primarily responsible for regulating processes that include mitochondrial OXPHOS, which generates ATP, as well as mitochondrial oxidative stress, apoptosis, calcium homeostasis, and mitophagy. Bone mesenchymal stem cells express factors that aid in bone formation and vascular growth. Positive regulation of hematopoietic stem cells in the bone marrow affects the differentiation of osteoclasts. Furthermore, the metabolic regulation of cells that play fundamental roles in various regions of the bone, as well as interactions within the bone microenvironment, actively participates in regulating bone integrity and aging. The maintenance of cellular homeostasis is dependent on the regulation of intracellular organelles, thus understanding the impact of mitochondrial functional changes on overall bone metabolism is crucially important. Recent studies have revealed that mitochondrial homeostasis can lead to morphological and functional abnormalities in senescent cells, particularly in the context of bone diseases. Mitochondrial dysfunction in skeletal diseases results in abnormal metabolism of bone-associated cells and a secondary dysregulated microenvironment within bone tissue. This imbalance in the oxidative system and immune disruption in the bone microenvironment ultimately leads to bone dysplasia. In this review, we examine the latest developments in mitochondrial respiratory chain regulation and its impacts on maintenance of bone health. Specifically, we explored whether enhancing mitochondrial function can reduce the occurrence of bone cell deterioration and improve bone metabolism. These findings offer prospects for developing bone remodeling biology strategies to treat age-related degenerative diseases.

Abstract
Osteoporosis is becoming a major concern in the field of public health. The process of bone loss is insidious and does not directly induce obvious symptoms. Complications indicate an irreversible decrease in bone mass. The high-risk populations of osteoporosis, including postmenopausal women, elderly men, diabetic patients and obese individuals need regular bone mineral density testing and appropriate preventive treatment. However, the primary changes in these populations are different, increasing the difficulty of effective treatment of osteoporosis. Determining the core pathogenesis of osteoporosis helps improve the efficiency and efficacy of treatment among these populations. Oxidative stress is a common pathological state secondary to estrogen deficiency, aging, hyperglycemia and hyperlipemia. In this review, we divided oxidative stress into the direct effect of reactive oxygen species (ROS) and the reduction of antioxidant enzyme activity to discuss their roles in the development of osteoporosis. ROS initiated mitochondrial apoptotic signaling and suppressed osteogenic marker expression to weaken osteogenesis. MAPK and NF-κB signaling pathways mediated the positive effect of ROS on osteoclast differentiation. Antioxidant enzymes not only eliminate the negative effects of ROS, but also directly participate in the regulation of bone metabolism. Additionally, we also described the roles of proinflammatory factors and HIF-1α under the pathophysiological changes of inflammation and hypoxia, which provided a supplement of oxidative stress-induced osteoporosis. In conclusion, our review showed that oxidative stress was a common pathological state in a high-risk population for osteoporosis. Targeted oxidative stress treatment would greatly optimize the therapeutic schedule of various osteoporosis treatments.

Abstract
Apigenin, a plant-derived flavonoid, was investigated to determine whether it could influence hydrogen peroxide (H2O2)-induced oxidative damage and cellular dysfunction in the MC3T3-E1 mouse osteoblastic cell line. In the present study, osteoblastic cells were treated with H2O2 in the presence or absence of apigenin. Cell viability, apoptosis, reactive oxygen species (ROS) production and mitochondrial membrane potential (ΔΨm) were subsequently examined. It was observed that H2O2 reduced cell survival and ΔΨm, while it markedly increased the intracellular levels of ROS and apoptosis. However, pretreatment of cells with apigenin attenuated all the H2O2-induced effects. The antioxidants, catalase and N-acetyl-L-cysteine (NAC) also prevented H2O2-induced oxidative cell damage. In addition, treatment with apigenin resulted in a significant elevation of osteoblast differentiation genes including alkaline phosphatase (ALP), collagen, osteopontin (OPN), osteoprotegerin (OPG), bone sialoprotein (BSP), osterix (OSX) and osteocalcin (OC) and bone morphogenetic proteins (BMPs) genes (BMP2, BMP4 and BMP7). In the mechanistic studies of cell signaling by the antioxidative potential of apigenin, it was found that apigenin activated the H2O2-induced decreased expression of phosphatidylinositol 3'-kinase (PI3K), protein kinase B2 (AKT2) genes and extracellular signal-related kinase (EPK) 2, which are key regulators of survival-related signaling pathways. By contrast, there were no changes in the expression of nuclear facor-κB (NF-κB) and c-Jun N-terminal kinase (JNK) gene exposed to H2O2 in the present study. Apigenin also upregulated the gene expression of antioxidant enzymes, superoxide dismutase (SOD) 1, SOD2 and glutathione peroxidase (GPx) 1. Taken together, these results suggested that apigenin attenuated oxidative-induced cell damage in osteoblastic cells and may be useful for the treatment of oxidative-related bone disease.

Abstract
In this study, Chrysanthemum zawadskii extract (CZE) was investigated to determine its effects on 2-deoxy-D-ribose (dRib)-induced oxidative damage and cellular dysfunction in the MC3T3-E1 mouse osteoblastic cell line. Osteoblastic cells were treated with the highly reducing sugar, dRib, in the presence or absence of CZE. Cell viability, apoptosis and reactive oxygen species (ROS) production were subsequently examined. It was observed that dRib reduced cell survival, while it markedly increased the intracellular levels of ROS and apoptosis. However, pre-treatment of the cells with CZE attenuated all the dRib-induced effects. The antioxidant, N-acetyl-L-cysteine (NAC), also prevented dRib-induced oxidative cell damage. In addition, treatment with CZE resulted in a significant increase in alkaline phosphatase (ALP) activity and collagen content, as well as in the expression of genes associated with osteoblast differentiation [ALP, collagen, osteopontin (OPN), osteoprotegerin (OPG), bone sialoprotein (BSP), osteocalcin (OC) and bone morphogenetic protein (BMP)2, BMP4 and BMP7]. In mechanistic studies of the antioxidative potential of CZE, we found that CZE reversed the dRib-induced decrease in the expression of phosphatidylinositol 3-kinase (PI3K) and protein kinase B (AKT)1 and AKT2 genes, which are master regulators of survival-related signaling pathways. CZE also upregulated the gene expression of the antioxidant enzymes, superoxide dismutase (SOD)2, SOD3 and glutathione peroxidase 4 (GPx4), which was inhibited by dRib. Taken together, these results suggest that CZE attenuates dRib-induced cell damage in osteoblastic cells and may be useful for the treatment of diabetes-associated bone disease.

Mitochondria and chloroplasts as the original sites of melatonin synthesis: a hypothesis related to melatonin's primary function and evolution in eukaryotes. J Pineal Res 2013; 54:127-38.

Abstract
Mitochondria and chloroplasts are major sources of free radical generation in living organisms. Because of this, these organelles require strong protection from free radicals and associated oxidative stress. Melatonin is a potent free radical scavenger and antioxidant. It meets the criteria as a mitochondrial and chloroplast antioxidant. Evidence has emerged to show that both mitochondria and chloroplasts may have the capacity to synthesize and metabolize melatonin. The activity of arylalkylamine N-acetyltransferase (AANAT), the reported rate-limiting enzyme in melatonin synthesis, has been identified in mitochondria, and high levels of melatonin have also been found in this organelle. From an evolutionary point of view, the precursor of mitochondria probably is the purple nonsulfur bacterium, particularly, Rhodospirillum rubrum, and chloroplasts are probably the descendents of cyanobacteria. These bacterial species were endosymbionts of host proto-eukaryotes and gradually transformed into cellular organelles, that is, mitochondria and chloroplasts, respectively, thereby giving rise to eukaryotic cells. Of special importance, both purple nonsulfur bacteria (R. rubrum) and cyanobacteria synthesize melatonin. The enzyme activities required for melatonin synthesis have also been detected in these primitive species. It is our hypothesis that mitochondria and chloroplasts are the original sites of melatonin synthesis in the early stage of endosymbiotic organisms; this synthetic capacity was carried into host eukaryotes by the above-mentioned bacteria. Moreover, their melatonin biosynthetic capacities have been preserved during evolution. In most, if not in all cells, mitochondria and chloroplasts may continue to be the primary sites of melatonin generation. Melatonin production in other cellular compartments may have derived from mitochondria and chloroplasts. On the basis of this hypothesis, it is also possible to explain why plants typically have higher melatonin levels than do animals. In plants, both chloroplasts and mitochondria likely synthesize melatonin, while animal cells contain only mitochondria. The high levels of melatonin produced by mitochondria and chloroplasts are used to protect these important cellular organelles against oxidative stress and preserve their physiological functions. The superior beneficial effects of melatonin in both mitochondria and chloroplasts have been frequently reported.

Abstract
Osteoporosis is a major health hazard and is a disease of old age; it is a silent epidemic affecting more than 200 million people worldwide in recent years. Based on a large number of chemical and pharmacological research many plants and their compounds have been shown to possess antiosteoporosis activity. This paper reviews the medicinal plants displaying antiosteoporosis properties including their origin, active constituents, and pharmacological data. The plants reported here are the ones which are commonly used in traditional medical systems and have demonstrated clinical effectiveness against osteoporosis. Although many plants have the potential to prevent and treat osteoporosis, so far, only a fraction of these plants have been thoroughly investigated for their physiological and pharmacological properties including their mechanism of action. An attempt should be made to highlight plant species with possible antiosteoporosis properties and they should be investigated further to help with future drug development for treating this disease.
