breast cancer bone metastasis lytic or blastic
2009, 7 (Suppl 7): S1-29. 2023 BioMed Central Ltd unless otherwise stated. The majority of breast cancer metastases ultimately cause bone loss. Podgorski I, Linebaugh BE, Koblinski JE, Rudy DL, Herroon MK, Olive MB, Sloane BF: Bone marrow-derived cathepsin K cleaves SPARC in bone metastasis. In the process, growth factors stored in the matrix, such as transforming growth factor (TGF)-, vascular endothelial growth factor (VEGF), insulin-like growth factors (IGFs), bone morphogenic proteins and fibroblast-derived factors, as well as calcium, are released into the bone microenvironment. Gradient Boosting Machine Identified Predictive Variables for Breast Cancer Patients Pre- and Post-Radiotherapy: Preliminary Results of an 8-Year Follow-Up Study. It has been suggested that cancer cells preferentially metastasize to bone due to their ability to express genes that are normally considered bone or bone-related [36]. Powles TJ, Clark SA, Easty DM, Easty GC, Neville AM: The inhibition by aspirin and indomethacin of osteolytic tumor deposits and hypercalcaemia in rats with Walker tumour, and its possible application to human breast cancer. While some of the growth factors produced by breast and prostate cancers may be different, ultimately they engage the bone re-modeling process. In fact, a new drug, denosumab (Prolia), a fully human monoclonal antibody to RANKL, has been approved by the US Food and Drug Administration (FDA) for the treatment of postmenopausal women with high risk of osteoporotic fractures, and is under priority review for patients with bone metastases. The .gov means its official. statement and 1999, London: Martin Dunitz Ltd. Raisz LG, Mundy GR, Luben RA: Skeletal reactions to neoplasms. Clinical studies of newly diagnosed breast cancer patients have revealed that high bone turnover correlates with a higher risk of skeletal complications [62]. Teriparatide is a recombinant peptide of parathyroid hormone that stimulates osteoblast activity and bone formation. Epub 2021 Jul 10. The tumors that develop, sometimes called lesions, can: Make the bones weaker and less dense. The majority of breast cancer metastases ultimately cause bone loss. The role of lining cells. N Engl J Med. However, more accessible and defined [76] models are needed. 10.1158/0008-5472.CAN-10-2179. It was also noted that tumor cells caused other cells in the bone (for example, lymphocytes) to produce molecules such as prostaglandins (PGs) that can affect bone [4]. Larkins TL, Nowell M, Singh S, Sanford GL: Inhibition of cyclooxygenase-2 decreases breast cancer cell motility, invasion and matrix metalloproteinase expression. PubMedGoogle Scholar. Prostate. Thus, the capacity of breast cancer cells to collaborate with osteoclasts is likely to be specific and is likely critical for them to cause osteolytic bone metastases. There are two types of lesions: lytic lesions, which destroy bone material; and blastic lesions, which fill the bone with extra cells. The clinical outcomes of bone pain, pathologic fractures, nerve compression syndrome, and metabolic disturbances leading to hypercalcemia and acid/base imbalance severely reduce the quality of life [3]. 10.1177/154405910608500703. Eventually, bone remodeling ceases as both osteoblasts and osteoclasts are lost. In a study by Mercer and Mastro [59], osteoblasts treated with conditioned media from MDA-MB-231 breast cancer cells displayed disorganized F-actin fibrils and reduced focal adhesion plaques. Bone. These cells fuse to form multinucleated, but non-functional pre-osteoclasts. DMS is a senior research technician with many years experience in the bone field. Bone is the most common site of metastasis for breast cancer. Their function is not clear except that their retraction is necessary for bone resorption to begin [10]. Methods Mol Biol. Oncogene. Nat Cell Biol. Orr and colleagues [5] have determined MMPs sufficient to resorb bone in vitro and to contribute to the process in vivo. Breast cancer had the highest . Osteolytic lesions are the end result of osteoclast activity; however, osteoclast differentiation and activation are mediated by osteoblast production of RANKL (receptor activator for NFB ligand) and several osteoclastogenic cytokines.

IL-8, a proinflammatory CXC chemokine, is secreted by monocytes, endothelial cells and osteoblasts. Primer on the Metabolic Bone Diseases and Disorders of Mineral Metabolism. 10.1111/j.1749-6632.1974.tb14480.x. Current treatments can improve bone density, decrease skeletal related events and ease bone pain, yet existing bone lesions do not heal. MMP-9 is important in the cascade leading to activation of VEGFA. 1997, 80 (8 Suppl): 1546-1556. 10.1016/j.rcl.2010.02.014. Often, bone metastases have both lytic and blastic features. Article AMM, the senior investigator and corresponding author, has worked in the area of breast cancer metastasis to bone for over 12 years. PubMed Central Marie L, Braik D, Abdel-Razeq N, Abu-Fares H, Al-Thunaibat A, Abdel-Razeq H. Cancer Manag Res. 2001, 285: 335-339. Clipboard, Search History, and several other advanced features are temporarily unavailable. Clin Adv Hematol Oncol. 2010. It has also been suggested that Runx2 is ectopically expressed in bone-destined metastatic breast cancer cells. -, Cell. Osteoblasts produce macrophage colony stimulating factor (M-CSF) and receptor activator of NFB ligand (RANKL), which bind to their respective receptors, c-fms and RANK, on pre-osteoclasts to bring about osteoclast differentiation and activation. Because of its significant role, TGF- has been a tempting therapeutic target. 2. While COX-1 is constitutively expressed in most tissues, COX-2 expression appears to be limited to brain, kidney, bone, reproductive organs and some neoplasms. These drugs may also cause cancer cell death; however, they may also negatively affect osteoblasts. C-SRC tyrosine kinase activity is associated with tumor colonization in bone and lung in an animal model of human breast cancer metastasis. Cancers (Basel). These factors can stimulate the tumor cells to proliferate and produce more growth factors and more PTHrP, further perpetuating the vicious cycle of bone metastasis. HDAC inhibitors stimulate LIFR when it is repressed by hypoxia or PTHrP in breast cancer. In the late 1980 s, PTHrP was linked to hypercalcemia in several cancers, providing evidence that PTHrP was involved in bone resorption. Thus, bone loss is due to both increased activation of osteoclasts and suppression of osteoblasts. Part of The cancer cells affect osteoblast morphology and extracellular matrix. The .gov means its official. Cancer. FOIA The other 20% of primary disease sites in both sexes are: kidney, thyroid, gastrointestinal tract and other locations. Exp Cell Res. While not directly responsible for osteolysis in metastatic breast cancer disease, there are physiological parameters that can amplify the degree of bone loss. For example, a hydroxyapatite scaold pre-loaded with bone morphogenetic protein-2 enhanced the growth rate of mammary tumor cells in the scaold [77]. 10.1210/er.19.1.18. Clinically, complications secondary to bone metastasis include pain, pathologic fractures, spinal cord compression, and hypercalcemia of malignancy. Pratap and colleagues [40] found that Runx2 responds to TGF- stimulation by activating the expression of Indian hedgehog (IHH), which further increases the level of PTHrP.

Despite the use of various therapeutic modalities, bone metastases eventually become resistant to therapy, and disease progresses.In this chapter, we describe the clinical picture and biological mechanism of bone metastases in breast cancer. Y-CC is a senior graduate student completing work on the studies of selenium in breast cancer metastasis. sharing sensitive information, make sure youre on a federal Another growth factor sequestered in the matrix is IGF. Cancer Res. Accessibility They follow the osteoclasts, reforming the bone matrix. 2007, 6: 2609-2617. 10.1158/1535-7163.MCT-07-0234. Doctors use imaging tests, such as x-rays, to figure out the types of . . Further stimulation results in large multinuclear cells capable of bone resorption. The results of an in vivo study showed that OPN-deficient mice showed significantly reduced bone metastasis [38]. 2010, 29: 811-821. Due to this, the bones get harder and cause the condition called sclerosis. Metastastic human breast cancer cells (MDA-MB-231) added to this culture attach, penetrate the tissue and form single cell files characteristic of metastases seen in pathologic tissues.

Below are the links to the authors original submitted files for images. At least three major growth factors sequestered in the matrix are activated by MMPs. This information is not easily obtained with in vitro studies. Metastatic bone lesions are the predominant malignancy to effect bone, with 15 times the occurrence rate of the next most common bone malignancy. (B) Metastatic breast cancer cells in the bone microenvironment secrete parathyroid hormone-related protein (PTHrP), cytokines and growth factors that negatively impact osteoblast function. Bone remodeling is often described as a cycle beginning with bone degradation and ending with bone deposition (Figure 1A). 2022 Feb;22(2):85-101. doi: 10.1038/s41568-021-00406-5. 2000, 2: 737-744. Corisdeo S, Gyda M, Zaidi M, Moonga BS, Troen BR: New insights into the regulation of cathepsin K gene expression by osteoprotegerin ligand. 1991 Apr 1;47(6):922-8 To date, osteoclasts have been the primary target of drug therapies. 10.1038/sj.bjc.6602417. J Bone Oncol. 2003, 349: 2483-2494. Bone Rep. 2022 Jun 12;17:101597. doi: 10.1016/j.bonr.2022.101597. Denosumab is an antibody directed to RANKL that prevents osteoclast differentiation. At first glance it would seem ideal to pair bisphosphonates or denosumab with teriparatide since the former two block bone resorption and the latter stimulates bone deposition. PubMed Breast cancer frequently metastasizes to the skeleton. These results signify an important role for cancer cell-derived Runx2 in the osteolytic process. They activate latent molecules released from the matrix. However, this approach has not entirely solved the problem. The bone remodeling microenvironment is a complex system in which the cell functions are controlled by multifunctional transcription factors, cytokines and growth factors. Lerner UH: Bone remodeling in post-menopausal osteoporosis. Jemal A, Siegel R, Ward E, Murray T, Xu J, Thun MJ: Cancer Statistics, 2007. 2019 Nov 29;21(1):130. doi: 10.1186/s13058-019-1220-2. PTH/PTHrP, TNF-, prostaglandins (PGE2), IL-1, IL-11, FGF-2, and IGF-1 have been reported to increase RANKL production. Despite the role of the osteoclasts in this process, the outcome is due in large part to the impact of cancer cells directly and indirectly on osteoblasts. Blood. Please enable it to take advantage of the complete set of features! Keywords: These types of tumors are called osteolytic, or simply lytic. Correspondence to Endocrinology. Breast cancer metastasis to the bone: mechanisms of bone loss. Bone metastasis can occur in any bone but more commonly occurs in the spine, pelvis and thigh. 10.3322/canjclin.57.1.43. MMP1, 2, 3 process the binding factors and free IGF, allowing it to bind to its receptors found both on osteoblasts and osteoclasts. Osteocytes may act as mechanosensing cells and initiate the process when microfractures and loading are involved. Aldridge SE, Lennard TW, Williams JR, Birch MA: Vascular endothelial growth factor acts as an osteolytic factor in breast cancer metastases to bone. Cholesterol Synthesis Is Important for Breast Cancer Cell Tumor Sphere Formation and Invasion. 10.1097/00003086-200004000-00013. Proff P, Romer P: The molecular mechanism behind bone remodelling: a review. In addition, production of inflammatory cytokines (that is, IL-6, TNF-, M-CSF, IL-1) is suppressed by estrogen [64]. In normal bone remodeling, osteoclasts secrete PDGF, which acts as a chemoattractant to recruit pre-osteoblasts to the site of bone repair [58]. The changes in the bone microenvironment then create a vicious cycle that further promotes bone destruction and tumor progression.Various therapeutic options are available for bone metastases of breast cancer. Am J Clin Oncol. In males, prostate and lung cancers make up 80% of carcinomas metastasising to bone. Assessment; Bone; Bone-targeted therapy; Detection; Mechanism of bone metastases; Metastasis; Therapy. This increase in COX-2 results in increased secretion of PGE2, which binds to EP4 receptors on the surface of the osteoblasts. Trabecular bone is the major site of bone turnover under normal conditions and in diseases of bone loss or formation. PubMed Central Just as osteoblasts are a critical partner in normal bone remodeling, they are vital to the metastatic osteolytic process. 1999, 59: 1987-1993. Guise TA, Kozlow WM, Heras-Herzig A, Padalecki SS, Yin JJ, Chirgwin JM: Molecular mechanisms of breast cancer metastases to bone. EMBO J.

CAS Bone metastasis significantly affects both quality of life and survival of the breast cancer patient. Bone metastases may cause pain, may make the bones more susceptible to fractures, and may cause increased levels of calcium in the blood. Other drugs on the horizon target TGF-, and cathepsin K. Various approaches, including kinase inhibitors, ligand-neutralizing antibodies and anti-sense molecules, are being investigated [33]. To accomplish the process of metastasis to bone, breast cancer cells are required to intrinsically possess or acquire the capacities that are necessary for them to proliferate, invade, migrate, survive, and ultimately arrest in bone. spinal cord compression) palpable mass deformity pathological fracture hypercalcemia bone marrow aplasia Nemeth JA, Harb JF, Barroso U, He Z, Grignon DJ, Cher ML: Severe combined immunodeficient-hu model of human prostate cancer metastasis to human bone. Both RANKL and VEGF can induce osteoclast formation [48], and MMPs play a role in bone matrix degradation. In addition, pre-clinical trials with agents that target cathepsin K, certain matrix metalloproteinases (MMPs), and transforming growth factor (TGF)- are underway. Bisphosphonates such as zoledronic acid (Zoledronate) bind to hydroxyapatite of the bone matrix and are ingested by osteoclasts, which then undergo apoptosis. 10.1007/s10911-005-5399-8. Mastro AM, Vogler EA: A three-dimensional osteogenic tissue model for the study of metastatic tumor cell interactions with bone. 10.1016/S1535-6108(03)00132-6. Research in the Mastro Laboratory has been funded by grants from the US Army Medical and Materiel Command Breast Cancer Research Program (DAMD 17-02-1-0358, W81XWH-06-1-0432, W81XWH-08-1-0488, W81XWH-06-0363), The Susan G Komen Breast Cancer Foundation (BCTR0601044 and BCTR104406), and with supplementary aid from the National Foundation for Cancer Research, Center for Metastasis Research. 60% of breast CA is blastic 90% of prostate CA is blastic cortical metastasis are common in lung cancer lesions distal to elbow and knee are usually from lung or renal primary studies Workup for older patient with single bone lesion and unknown primary includes imaging plain radiographs CT of chest / abdomen / pelvis technetium bone scan labs Rucci N, Teti A: Osteomimicry: how tumor cells try to deceive the bone. 2010, 87: 401-406. 2005, 24: 2543-2555. Rev Endocr Metab Disord. Clinical evidence indicates that this drug can reduce the rate of bone loss, but is not curative. Lee J, Weber M, Mejia S, Bone E, Watson P, Orr W: A matrix metalloproteinase inhibitor, batimastat, retards the development of osteolytic bone metastases by MDA-MB-231 human breast cancer cells in Balb C nu/nu mice. However, the process is described in brief in order to further consider the mechanisms of osteolytic metastasis. Am J Pathol. Retrieval of the bone at specific times gives a snapshot of the status of metastases. Cancer Res. Lytic lesions should have radiologic evidence of calcication . Induction of aberrant osteoclastogenesis is only part of the equation. On x-rays, these metastases show up as spots that are whiter than the bone around them. The presence of metastatic lesions in bone disrupts the normal bone microenvironment and upsets the fine balance between the key components. In addition, its expression is enhanced in the presence of TGF- [20]. An official website of the United States government. The site is secure. Cathepsin K is the major mediator of bone resorption, controlling the osteoclast portion of the vicious cycle. When treated with neutralizing antibody to PDGF, the osteoblasts assumed normal morphology. Balkwill F, Mantovani A: Cancer and inflammation: implications for pharmacology and therapeutics. 10.1016/S0006-291X(02)02937-6. There are many excellent reviews describing this paradigm [1417] from its inception in the 1990 s. The minimal essential components are osteoblasts, osteoclasts, tumor cells and the mineralized bone matrix. Among these are the MMPs. 10.1158/1078-0432.CCR-09-0426. While the case for the importance of MMPs as metastasis regulators is strong, they themselves are regulated by tissue inhibitors of metalloproteinase (TIMPs). Cancer cells, osteoblasts, osteoclasts and endothelial cells produce MMPs. Inflammation associated with bone fractures and arthritic joints has been anecdotally associated with the appearance of bone metastasis, often many years after the primary tumor has been treated. 2010, [Epub ahead of print]. 10.1158/1535-7163.MCT-08-0153. Because bone metastasis is extremely common in patients with metastatic breast cancer, clinical management of bone metastases is an important and challenging aspect of treatment in the metastatic setting.The skeleton is a metabolically active organ system that undergoes continuous remodeling throughout life. Hillner BE, Ingle JN, Berenson JR, Janjan NA, Albain KS, Lipton A, Yee G, Biermann JS, Chlebowski RT, Pfister DG. prostate = blastic/sclerotic . Radiotracer is taken up only by activated osteoblasts and as such, bone scans are quite often negative even with extensive skeletal involvement by myeloma [ 5 ]. Another drug, teriparatide (Forteo), the amino-terminal 34 amino acids of parathyroid hormone, has been used for many years to treat osteoporosis. Annu Rev Pathol. Disclaimer, National Library of Medicine Cancer Res. Cancer cells also can elicit an increase in osteoblast production of several other osteoclastogenic cytokines, such as monocyte chemotactic protein-1 (MCP-1) and IL-6, IL-8 and TNF [22]. 1988 Jun;7(2):143-88 The entry of breast cancer cells into the bone micro-environment synergistically increases the complexity of cell-cell interactions. 2023;2582:343-353. doi: 10.1007/978-1-0716-2744-0_24. Other cells of the osteoblastic lineage include bone lining cells and osteocytes. The MMPs are considered to be important in the bone metastatic process. At the tissue level, PDGF is involved in bone formation, wound healing, erythropoiesis and angiogenesis as well as tumor growth and lesion development [57]. We present therapeutic options for bone metastasis using a multidisciplinary approach. Osteomimetic factors driven by abnormal Runx2 activation in breast cancer cells may increase their survival in the bone microenvironment. Metastatic breast cancer cells or their conditioned media increase osteoblast apoptosis, and suppress osteoblast differentiation and expression of proteins required for new bone matrix formation. Bussard KM, Venzon DJ, Mastro AM: Osteoblasts are a major source of inflammatory cytokines in the tumor microenvironment of bone metastatic breast cancer. COX-2 inhibition also partially attenuated the ability of two breast cancer cell lines to degrade and invade extracellular matrix components such as laminin and collagen [47]. 3 Osteoblastic or blastic metastases cause an area of the bone to look denser or sclerotic. Cancer. Clinically, complications secondary to bone metastasis include pain, pathologic fractures, spinal cord compression, and hypercalcemia of malignancy. However, teriparatide is associated with an increased risk of osteosarcoma and exacerbation of skeletal metastases because of its effect on bone turnover [75]. At least three essential molecules, TGF-, IGF, and VEGF, need to be activated by MMPs before they can function. 10.1158/0008-5472.CAN-09-2758. It can activate osteoclasts independent of RANKL [21]. Several of these RANKL inducers merit further discussion with respect to metastatic breast cancer-induced osteolysis. 10.1038/35036374. Once breast cancer cells arrest in bone, bone is a storehouse of a variety of cytokines and growth factors and thus provides an extremely fertile environment for the cells to grow. Bone metastasis significantly affects both quality of life and survival of the breast cancer patient. Cathepsin K is believed to be the major protease in this capacity. Osteo-blasts also produce osteoprotegerin (OPG), a decoy receptor to RANKL that curtails osteoclast activation. Current therapies consist of blocking osteoclast activity as a means of disrupting the vicious cycle. While the outcome is predominantly osteoblastic, it is known that prostate cancer lesions display both blastic and lytic characteristics early in the process. Bone. The lesions can often be blastic but may also appear purely lytic, with poor margination, no matrix and cortical destruction. 10.1359/jbmr.060610. Bergers G, Brekken R, McMahon G, Vu TH, Itoh T, Tamaki K, Tanzawa K, Thorpe P, Itohara S, Werb Z, Hanahan D: Matrix metalloproteinase-9 triggers the angiogenic switch during carcinogenesis. Metastases leading to overall bone loss are classified as osteolytic. Biochem Biophys Res Commun. 2005, 310: 270-281. Breast cancer metastasis to the bone: mechanisms of bone loss, http://breast-cancer-research.com/series/metastasis_pathway. Would you like email updates of new search results? Identification of a stimulator or protector of osteoblasts would be a major improvement in treatment for osteolytic breast cancer as well as other diseases of bone loss. 10.1097/SPC.0b013e32832f4149. Osteoclasts derive from hematopoietic stem cells. The dynamics of this system are interrupted when metastatic breast cancer cells are introduced, adding another layer of active molecules to the bone environment. Department of Biochemistry and Molecular Cell Biology, The Pennsylvania State University, University Park, PA, 16802, USA, Yu-Chi Chen,Donna M Sosnoski&Andrea M Mastro, You can also search for this author in The PGE2-mediated production of RANKL induces osteoclastogenesis via RANK. For females, breast and lung are the most common primary sites ; nearly 80% of cancers that spread to the skeleton are from these locations. The role of PTHrP in bone metabolism is not fully understood, but it is known to cause upregulation of RANKL and downregulation of OPG [19], thus enhancing osteoclast function leading to bone degradation. 10.1038/sj.bjc.6601437. We also discuss known risk factors as well as detection and assessment of bone metastases. 10.1007/s10585-007-9112-8. In the presence of cancer cells, osteoblasts increase expression of pro-inflammatory cytokines such as IL-6, monocyte chemotactic protein-1 (MCP-1), macrophage inflammatory protein-2 (MIP-2; GRO alpha human), keratinocyte chemoattractant (KC; IL-8 human) and VEGF. J Bone Miner Res. eCollection 2022. The cells that have spread to the bone are breast cancer cells. These molecules bind to hydroxyapatite of the bone matrix and are ingested by osteoclasts, which then undergo apoptosis. 2010, 70: 6537-6547. Br J Cancer. Even in adults it is estimated that about 10% of the bone is renewed each year [7]. The use of blocking antibodies to placental growth factor in two xenograft mouse/human models greatly decreased the numbers and size of osteolytic lesions [61]. Google Scholar. Mol Cancer Ther. Br J Cancer. It was recently reported that mice deficient in vitamin D or calcium showed increased metastatic tumor growth and accelerated rates of bone resorption [66, 67]. 2016 Apr 1;99(Pt B):206-211. doi: 10.1016/j.addr.2015.11.017. Lynch CC: Matrix metalloproteinases as master regulators of the vicious cycle of bone metastasis. However, both bone degradation and deposition likely occur early in the metastatic process. HHS Vulnerability Disclosure, Help Exp Cell Res. 1997 Oct 15;80(8 Suppl):1572-80. doi: 10.1002/(sici)1097-0142(19971015)80:8+<1572::aid-cncr7>3.3.co;2-d.

Where do the MMPs come from? Wang Y, Nishida S, Elalieh HZ, Long RK, Halloran BP, Bikle DD: Role of IGF-I signaling in regulating osteoclastogenesis. Continuing research into the mechanisms of cancer cell dormancy could result in a treatment that would prevent cancer cell proliferation in the bone and the chain of events that leads to osteolysis. IGF, insulin-like growth factor; MCP-1, monocyte chemotactic protein-1; PDGF, platelet-derived growth factor; VEGF, vascular endothelial growth factor. This approach will allow testing of components and drugs in a model less complex than an animal but more relevant than standard tissue culture. IL-11, normally produced by bone marrow stromal cells and osteoblasts, is an important regulator of hematopoiesis and a potent promoter of osteoclast formation. 2009, 69: 4097-4100. Bethesda, MD 20894, Web Policies These functional molecules complete the cycle and osteolysis continues. Several groups have developed in vivo models in which bone or bone substitutes are implanted in animals. In people with breast and prostate cancer, the bone is often the first distant site of cancer spread. -, Cancer Metastasis Rev. Once bony metastases occur, cancer cure becomes impossible and in these cases radiation therapy, associated or not with systemic chemotherapy, may be . Feng X, McDonald JM: Disorders of bone remodeling. Ooi LL, Zhou H, Kalak R, Zheng Y, Conigrave AD, Seibel MJ, Dunstan CR: Vitamin D deficiency promotes human breast cancer growth in a murine model of bone metastasis. RANKL and other pro-osteoclastogenic cytokines are increased with a concomitant reduction in OPG, resulting in more osteoclast formation and bone degradation. We are in the process of adding osteoclasts to the system to create a rudimentary in vitro bone remodeling unit. 8600 Rockville Pike 2000, 373: 104-114. PTHrP, one of many proteins controlled by Runx2, is a major effector in breast cancer bone metastasis progression and bone loss. 10.1182/blood-2009-08-237628. 10.1016/S0531-5565(03)00069-X. The presence of tumor cells in the bone microenvironment perturbs the balance between osteoblasts and osteoclasts, leading to excess bone loss or formation. In the young adult, bone mass reaches its peak, but with increasing age there is a slow loss of mass. Furthermore, Pozzi and colleagues [30] have recently reported that high doses of zoledronic acid, the current standard therapeutic for most osteolytic diseases, may also negatively affect osteoblast differentiation.
