Yang Y, Ren Y, Ramani VC, Nan L, Suva LJ, Sanderson RD: Heparanase enhances local and systemic osteolysis in multiple myeloma by upregulating the expression and secretion of RANKL. An official website of the United States government. There is also evidence that molecules in conditioned medium from PC-3 cells alone [34], or from both PC-3 cells and MC3T3-E1 osteoblasts [35], promote osteoclastogenesis. It should be noted that in addition to obvious members of the vicious cycle, other factors are produced during the process, including inflammatory cytokines, which significantly affect tumor cell survival, cell differentiation, and angiogenesis. In reality the system is much more complex (Table 1). In light of these findings, correction of calcium and vitamin D deficiencies should be considered as adjuvant therapies in slowing or preventing osteolysis in breast cancer patients.

The main symptoms of breast cancer that has spread to bone are: 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]. Using this device, we have been able to grow osteoblasts into a mineralized tissue. Am J Clin Oncol. Induction of aberrant osteoclastogenesis is only part of the equation. Assessment; Bone; Bone-targeted therapy; Detection; Mechanism of bone metastases; Metastasis; Therapy. Endocrinology. This area has been likened to an extracellular lysosome [11]. It improves the quality of life by preventing fractures but does not prolong life [73]. Recent research has revealed how cancer cell Runx2 affects other cells in the bone microenvironment and promotes osteolysis. Denosumab is an antibody directed to RANKL that prevents osteoclast differentiation. 2010, 70: 1835-1844. Osteoblasts themselves are negatively affected by cancer cells as evidenced by an increase in apoptosis and a decrease in proteins required for new bone formation. In males, prostate and lung cancers make up 80% of carcinomas metastasising to bone. Runx2 downregulates proliferation and induces p21, RANKL, MMP2, MMP9, MMP13, VEGF, OPN, bone sialoprotein and PTHrP protein expression to promote osteoblast differentiation, bone development and turnover [39]. Clin Pharmacol Ther. It inhibits the differentiation of osteoclasts by competitive binding with RANKL. Disclaimer, National Library of Medicine Halpern J, Lynch CC, Fleming J, Hamming D, Martin MD, Schwartz HS, Matrisian LM, Holt GE: The application of a murine bone bioreactor as a model of tumor: bone interaction. MeSH However, both drugs are associated with low incidence of osteonecrosis of the jaw [75]. Bone. Other molecules made by multiple myeloma cells, such as IL-3, IL-7 and soluble frizzle-related protein-2, also inhibit osteoblast differentiation [27]. Osteoclasts derive from mononuclear myeloid precursors that fuse to form pre-osteoclasts. Nevertheless, the inaccessibility, opacity and size of the skeleton make it difficult to study even in laboratory animals. The mechanisms are thought to be inhibition of tumor cell adhesion as well as osteoclast differentiation. 10.1002/(SICI)1097-0142(19971015)80:8+<1546::AID-CNCR4>3.0.CO;2-I. Mol Cancer. and transmitted securely. Chen, YC., Sosnoski, D.M. There are conflicting reports regarding their effect on osteoblasts. The tumors that develop, sometimes called lesions, can: Make the bones weaker and less dense. 1997, 80 (8 Suppl): 1572-1580. sharing sensitive information, make sure youre on a federal PubMed The majority of bone metastases are asymptomatic. Home; Study Search; Study Details From Other Databases Runx2 also promotes PTHrP expression in breast cancer cells, which in turn stimulates other cells, such as osteoblasts, to produce more RANKL, leading to further osteoclast activation.

Kubota K, Sakikawa C, Katsumata M, Nakamura T, Wakabayashi K: PDGF BB purified from osteoclasts acts as osteoblastogenesis inhibitory factor (OBIF). The https:// ensures that you are connecting to the While drugs that inhibit osteoclast differentiation or activity are vital to treating osteolysis, therapies designed to restore osteoblast number and function will be required to fully resolve osteolytic lesions. 10.1158/0008-5472.CAN-09-3194. 10.1177/154405910608500703. Ann N Y Acad Sci. Further, we describe future directions for bone metastasis management, focusing on novel bone-specific targeted therapies. Bone metastases from breast cancer are typically lytic, meaning that there is area of bone destruction at the site of metastasis. Guise TA, Mundy GR: Cancer and bone. . 1973, 28: 316-321. J Clin Oncol. Proff P, Romer P: The molecular mechanism behind bone remodelling: a review. The hypoactivity of osteoblasts has been known for some time in multiple myeloma. PubMed Central Osteoclasts derive from hematopoietic stem cells. Studies with MMP9-null mice indicate its importance in tumor progression in ovarian cancer, prostate cancer and bone metastasis [56]. Lytic lesions are caused by cancer cells causing old bone to break down without new bone being . Matrix degradation appears to be only one of the roles of MMPs. The normal processes of bone resorption and formation are remarkably well balanced. Gan To Kagaku Ryoho. Bethesda, MD 20894, Web Policies As might be expected from the nature of the osteolytic process, that is, the degradation of bone, the microenvironment contains many proteases. Ann N Y Acad Sci. 2022 Aug 23;14:2519-2531. doi: 10.2147/CMAR.S369910. prostate = blastic/sclerotic . 10.1007/s10585-006-9044-8. PTH/PTHrP, TNF-, prostaglandins (PGE2), IL-1, IL-11, FGF-2, and IGF-1 have been reported to increase RANKL production. While they are categorized into functional groups, it should be noted that many of these factors are multifunctional and must be considered within the context of the bone remodeling system as a whole. In addition, production of inflammatory cytokines (that is, IL-6, TNF-, M-CSF, IL-1) is suppressed by estrogen [64]. 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. 2006, 85: 584-595. Bone metastasis may be the first sign that you have cancer, or bone metastasis may occur years after cancer treatment. Prostate. In the late 1980 s, PTHrP was linked to hypercalcemia in several cancers, providing evidence that PTHrP was involved in bone resorption. Guise TA, Kozlow WM, Heras-Herzig A, Padalecki SS, Yin JJ, Chirgwin JM: Molecular mechanisms of breast cancer metastases to bone. CA Cancer J Clin. 2010, 2: 907-915. Y-CC is a senior graduate student completing work on the studies of selenium in breast cancer metastasis. Osteocytes are terminally differentiated osteoblasts that become embedded in the bone matrix at the end of the deposition phase of remodeling. Both RANKL and VEGF can induce osteoclast formation [48], and MMPs play a role in bone matrix degradation. Manage cookies/Do not sell my data we use in the preference centre. 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]. However, the MMPs may be involved in matrix remodeling once the osteoclasts are finished. However, PTHrP does not directly stimulate osteoclast differentiation, but rather stimulates other cells to increase RANKL and decrease OPG production. Bendre M, Montague DC, Peery T, Akel NS, Gaddy D, Suva LJ: Interleukin-8 stimulation of osteoclastogenesis and bone resorption is a mechanism for the increased osteolysis of metastatic bone disease. 2006, 21: 1350-1358. 2022 Feb;22(2):85-101. doi: 10.1038/s41568-021-00406-5. These molecules cause osteoblasts not only to form new bone but also to release RANKL and other osteoclastic mediators. 2018 Mar;96:63-78. doi: 10.1016/j.biocel.2018.01.003. 2009, 15: 5829-5839. 2010, 8: 159-160. The MMP family, composed of more than 20 members, can collectively degrade all components of the extracelluar matrix. (A) The bone remodeling unit consists of osteoblasts, which produce osteoid, bone matrix, and osteoclasts, which degrade mineralized bone. Juarez P, Guise TA: TGF-beta in cancer and bone: Implications for treatment of bone metastases. In the context of the current discussion, cancer cells may initiate the process. eCollection 2022 Dec.

Bone metastases result in lesions or injury to the bone tissue. 10.1016/S1535-6108(03)00132-6. 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]. Heterogeneity of tumor cells in the bone microenvironment: Mechanisms and therapeutic targets for bone metastasis of prostate or breast cancer. At higher doses they may in fact prevent osteoblast differentiation [30]. 2005, 10: 169-180. The average survival after the diagnosis of a breast cancer metastasis to bone has dramatically . In addition, factors such as TGF- and IGFs that are released from the bone matrix during degradation serve to increase PTHrP expression in breast cancer cells. & Mastro, A.M. 10.1158/1078-0432.CCR-05-1806. MeSH Drugs of the bisphosphonate family have been used for many years as the standard of care. Eur J Cancer. These drugs may also cause cancer cell death; however, they may also negatively affect osteoblasts. PubMed Article Cells of the immune system, T cells and dendritic cells can also express RANKL. 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]. Understanding the mechanisms of osteolysis should be the key to designing the cure. Osteo-blasts also produce osteoprotegerin (OPG), a decoy receptor to RANKL that curtails osteoclast activation. 2008, 314: 173-183. Retrieval of the bone at specific times gives a snapshot of the status of metastases. 10.1038/sj.bjc.6601437. Cathepsin K is the major mediator of bone resorption, controlling the osteoclast portion of the vicious cycle. 10.1158/0008-5472.CAN-07-1046. It is common to find increased PTHrP serum levels in breast cancer patients. Hadjidakis DJ, Androulakis II: Bone remodeling. Chemotherapy may bring about ovarian failure and premature menopause [1]. Roy DL, Pathangey LB, Tinder TL, Schettini JL, Gruber HE, Mukherjee P: Breast-cancer-associated metastasis is significantly increased in a model of autoimmune arthritis. Once bony metastases occur, cancer cure becomes impossible and in these cases radiation therapy, associated or not with systemic chemotherapy, may be . Clinical evidence indicates that this drug can reduce the rate of bone loss, but is not curative. The site is secure. EMBO J. By knowing the typical behavior of the metastatic lesion - lytic or blastic - you can help sort between the types to make the mnemonic even more useful. 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. As seen in the images here, multiple, confluent sclerotic, blastic bony lesions are typical of metastatic breast cancer. Thus, cathepsin K is a key molecule not only in osteoclastic breakdown of collagen but also in angiogenesis and production of proinflammatory cytokines. Cholesterol Synthesis Is Important for Breast Cancer Cell Tumor Sphere Formation and Invasion. Mouse Models of Tumor Bone Metastasis and Invasion for Studying CCN Proteins. It can activate both Smad-dependent and Smad-independent signal pathways to induce preosteolytic factors such as PTHrP [23]. Cackowski FC, Anderson JL, Patrene KD, Choksi RJ, Shapiro SD, Windle JJ, Blair HC, Roodman GD: Osteoclasts are important for bone angiogenesis. Guise [18] demonstrated that increasing the expression of PTHrP in cancer cells enhanced osteolytic lesions in vivo, while decreasing the expression reduced the number and size of lesions. 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. 2009, 3: 213-218. Cells of the osteoblast lineage are derived from mesenchymal stem cells, and are represented in this unit by osteoblasts, bone lining cells and osteocytes. The authors declare that they have no competing interests. 10.1016/S8756-3282(03)00086-3. 2022 Dec 2;11(12):2394. doi: 10.3390/antiox11122394. eCollection 2022. 1998, 19: 18-54. 2000, 2: 737-744.

Osteoblast differentiation is suppressed; new osteoid production is no longer able to keep pace with bone resorption. 10.1007/s10585-007-9112-8. Fragments of human fetal bone implanted in SCID mice allow one to examine human cancer with human bone [76]. 2003, 33: 28-37. As pointed out by Lynch, the spatial and temporal expression of these molecules is of utmost importance. Their function is not clear except that their retraction is necessary for bone resorption to begin [10]. Of the many prostaglandins, PGE2 is known to play a critical role in cancer progression. Osteomimetic factors driven by abnormal Runx2 activation in breast cancer cells may increase their survival in the bone microenvironment. PubMed A delicate balance of the bone-forming osteoblasts and bone-resorbing osteoclasts in the dynamic microenvironment of the skeleton maintains normal bone remodeling and integrity. Once osteoblasts finish bone deposition, they undergo apoptosis, remain in the matrix as osteocytes or revert to thin bone-lining cells. Morrissey C, Lai JS, Brown LG, Wang YC, Roudiffer MP, Coleman IM, Gulati R, Vakar-Lopez F, True LD, Corey E, Nelson PS, Vessella RL: The expression of osteoclastogenesis-associated factors and osteoblast response to osteolytic prostate cancer cells. These types of tumors are called osteolytic, or simply lytic. Google Scholar, Mundy GR: Bone Remodeling and its Disorders. The bone remodeling microenvironment is a complex system in which the cell functions are controlled by multifunctional transcription factors, cytokines and growth factors. However, this approach has not entirely solved the problem. Here we discuss some of the proposed mechanisms that contribute to metastatic breast cancer-induced bone loss. Epub 2021 Oct 5. Annu Rev Pathol. Actions of bisphosphonate on bone metastasis in animal models of breast carcinoma. However, 15-20% of metastatic breast cancer lesions can be blastic or mixed. Disclaimer, National Library of Medicine 1991 Apr 1;47(6):922-8 Clin Cancer Res. California Privacy Statement, Distinct tumor microenvironments of lytic and blastic bone metastases in prostate cancer patients The most common metastatic lesions of prostate cancer are in bone and can be classified into three distinct pathology subtypes: lytic, blastic, and an indeterminate mixture of both. 2021 Aug;40(34):5314-5326. doi: 10.1038/s41388-021-01931-1. 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. While the outcome is predominantly osteoblastic, it is known that prostate cancer lesions display both blastic and lytic characteristics early in the process. For post-menopausal women, high bone turnover may be caused by estrogen deficiency. This molecule is also produced by metastatic breast cancer cells [49]. Article IL-8, a proinflammatory CXC chemokine, is secreted by monocytes, endothelial cells and osteoblasts. Symptoms can arise in a number of scenarios 1,3,6: local bone pain soft tissue mass resulting in: direct compression of adjacent structures by extraosseous soft tissue mass (e.g. In patients with lytic or mixed lytic/blastic from solid tumor metastases, there was a 100% concordance between FDG-PET and needle biopsy when using an SUV cutoff of 2 33 33 . Those leading to excess bone deposition are considered osteoblastic. The bone microenvironment. While there is evidence that the breast cancer cell matrix metalloproteinases (MMPs) can resorb bone in vitro and contribute to bone degradation in vivo [5], it is now well accepted that osteoclasts are largely responsible for osteolytic metastatic lesions [6]. Mol Cancer Ther. Purpose: This is a study in adult patients with different types of cancer. MMPs are involved in the bone remodeling process after osteoclasts are finished. Thus, bone loss is due to both increased activation of osteoclasts and suppression of osteoblasts. The receptor binding activity in turn causes an increase in production of RANKL. It is estimated that 85% of individuals with advanced disease harbor bone metastases [1]. 2010, 9: 122-10.1186/1476-4598-9-122. 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. Clin Cancer Res. Please enable it to take advantage of the complete set of features! (B) Metastatic breast cancer cells in the bone microenvironment secrete parathyroid hormone-related protein (PTHrP), cytokines and growth factors that negatively impact osteoblast function.

Akech and colleagues [34] recently reported that Runx2 (Runt-related transcription factor 2) is produced by the highly metastatic prostate cancer cell PC-3, and positively correlates to the severity of osteolytic disease. In the bone, OPN is involved in the differentiation and activity of osteoclasts, and inhibition of mineral deposition in the osteoid [37]. Kang Y, Siegel PM, Shu W, Drobnjak M, Kakonen SM, Cordon-Cardo C, Guise TA, Massague J: A multigenic program mediating breast cancer metastasis to bone. Breast cancer bone metastases: pathogenesis and therapeutic targets. Cancer. However, both bone degradation and deposition likely occur early in the metastatic process. It's not the same as having cancer that starts in the bone. The site is secure. They follow the osteoclasts, reforming the bone matrix. In the early 1970 s it was reported that prostaglandins could resorb fetal bone in culture [43], and that aspirin, a COX-1 inhibitor, and indomethacin, a COX-2 inhibitor, could prevent osteolysis in tissue culture [44]. HDAC inhibitors induce LIFR expression and promote a dormancy phenotype in breast cancer. The mean standardized uptake value (SUV) for tumor was 7.1 versus 2.1 for benign lesions. 2010, 33 (3 Suppl): S1-7. A smoking history is almost always present. 10.1006/bbrc.2001.5127. However, more accessible and defined [76] models are needed. They activate latent molecules released from the matrix. Edited by: Rosen CL. Breast Cancer Res 12, 215 (2010).

Clinical Characteristics, Prognostic Factors and Treatment Outcomes of Patients with Bone-Only Metastatic Breast Cancer. Clinical studies of newly diagnosed breast cancer patients have revealed that high bone turnover correlates with a higher risk of skeletal complications [62]. In males, prostate and lung cancers make up 80% of carcinomas metastasizing to bone. Federal government websites often end in .gov or .mil. Metastatic breast cancer cells tend to spread to the bones more often than they do to other parts of the body. J Dent Res. 7, Chapter Cortical bone provides strength and protection while trabecular bone is the most metabolically active. Curr Opin Support Palliat Care. IL-11, normally produced by bone marrow stromal cells and osteoblasts, is an important regulator of hematopoiesis and a potent promoter of osteoclast formation. 10.1111/j.0105-2896.2005.00326.x. Cookies policy. J Natl Compr Canc Netw. A working model to describe the bone remodeling compartment in the presence of metastatic cancer cells has been referred to as the 'vicious cycle of bone metastasis' [13] (Figure 1B). In a recent comprehensive review article, Lynch [50] presents the case that they are 'master regulators' of the vicious cycle. It is impossible to understand the growth and progression of cancer cells in the bone marrow without consideration of the interaction between osteoblasts and osteoclasts. Metastatic breast cancer (also called stage IV or advanced breast cancer) is not a specific type of breast cancer. 10.3816/CBC.2005.s.004. Radiol Clin North Am. 10.1097/SPC.0b013e32832f4149. Estrogen also increases osteoblast pro-collagen synthesis and decreases osteoblast apoptosis [63]. Myeloma cells may also produce RANKL and directly affect osteoclasts [28].
