Article Interestingly, many osteomimetic factors are regulated by the same transcription factor, Runx2, considered to be the major regulator of osteoblast commitment and differentiation [39]. Radiol Clin North Am. 10.2741/S110. 1999, 59: 1987-1993. quiz S30, CAS 2005, 5 (Suppl): S46-53. Guise TA, Mundy GR: Cancer and bone. Teriparatide is a recombinant peptide of parathyroid hormone that stimulates osteoblast activity and bone formation. It binds to two class III tyrosine kinase receptors, PDGFR and PDGFR, leading to activation of several signaling molecules. AMM, the senior investigator and corresponding author, has worked in the area of breast cancer metastasis to bone for over 12 years. These functional molecules complete the cycle and osteolysis continues. Epub 2021 Jul 10. Lefley D, Howard F, Arshad F, Bradbury S, Brown H, Tulotta C, Eyre R, Alfrez D, Wilkinson JM, Holen I, Clarke RB, Ottewell P. Breast Cancer Res.

Clipboard, Search History, and several other advanced features are temporarily unavailable. These capacities are essential for any cancer cells to develop distant metastases in organs such as lungs and liver as well as bone. 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. 1988 Jun;7(2):143-88 Commonly, human cancer cells are studied as xenografts in immunodeficient mice, or rodent tumors are studied in syngeneic models. Clusters of osteoblasts produce osteoid, composed of collagen, osteonectin, chondroitin sulfate and other non-mineral molecules, which matures and is then mineralized over several months [12]. Bussard KM, Venzon DJ, Mastro AM: Osteoblasts are a major source of inflammatory cytokines in the tumor microenvironment of bone metastatic breast cancer. In the highly metastatic, COX-2-expressing breast cancer cell line Hs578T, treatment with the selective COX-2 inhibitor Ns-398 markedly decreased the production of MMP1, 2, 3, and 13 in a dose-dependent manner. In a series of in vitro, ex vivo and in vivo experiments, Ohshiba and colleagues [45] demonstrated that direct cell-cell contact between breast cancer cells and osteoblasts caused an increase in COX-2 expression in the osteoblasts due to activation of the NFB/mitogen-activated protein (MAP) kinase pathway. 3 Br J Cancer. Often, bone metastases have both lytic and blastic features. 2005, 310: 270-281. Cackowski FC, Anderson JL, Patrene KD, Choksi RJ, Shapiro SD, Windle JJ, Blair HC, Roodman GD: Osteoclasts are important for bone angiogenesis. Privacy Epub 2015 Dec 4. Lynch CC: Matrix metalloproteinases as master regulators of the vicious cycle of bone metastasis. Metastatic breast cancer (also called stage IV or advanced breast cancer) is not a specific type of breast cancer. (A) The bone microenvironment under conditions of normal bone remodeling; (B) and in the presence of osteolytic bone metastases. Once bony metastases occur, cancer cure becomes impossible and in these cases radiation therapy, associated or not with systemic chemotherapy, may be . The roles of cell adhesion molecules including cadherins and laminin and matrix metalloproteinases in the development of osteolytic bone metastases by breast cancer are also discussed. Some non-cancerous processes can appear similar to metastatic disease to the bone on imaging and MRI. 2008, 314: 173-183. However, teriparatide is associated with an increased risk of osteosarcoma and exacerbation of skeletal metastases because of its effect on bone turnover [75]. -, Proc Natl Acad Sci U S A. HDAC inhibitors induce LIFR expression and promote a dormancy phenotype in breast cancer. 2010. Rev Endocr Metab Disord. 10.1158/1078-0432.CCR-09-0426. Am J Pathol. PubMedGoogle Scholar.

Their multifunctionality demonstrates their importance. Anyone you share the following link with will be able to read this content: Sorry, a shareable link is not currently available for this article. In the final stages of metastatic osteolytic breast cancer disease, the cancer cells, fueled by growth factors released from the degraded matrix, expand unchecked. California Privacy Statement, 10.3816/CBC.2005.s.004. Breast cancer frequently metastasizes to the skeleton. 2023;2582:343-353. doi: 10.1007/978-1-0716-2744-0_24. RANKL and other pro-osteoclastogenic cytokines are increased with a concomitant reduction in OPG, resulting in more osteoclast formation and bone degradation. IL-8, a proinflammatory CXC chemokine, is secreted by monocytes, endothelial cells and osteoblasts. 10.1016/j.rcl.2010.02.014. -, Cancer Metastasis Rev. 1973, 28: 316-321. 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. Manage cookies/Do not sell my data we use in the preference centre. Bone metastases may cause pain, may make the bones more susceptible to fractures, and may cause increased levels of calcium in the blood. Nevertheless, they do not appear to function in the osteoclast resorption lacuna, probably due to the low pH in this compartment. (B) Metastatic breast cancer cells in the bone microenvironment secrete parathyroid hormone-related protein (PTHrP), cytokines and growth factors that negatively impact osteoblast function. 2006, 1092: 385-396. For example, OPN is produced by many breast cancer cells and has a strong clinical correlation with poor prognosis and decreased survival [37]. Mastro AM, Vogler EA: A three-dimensional osteogenic tissue model for the study of metastatic tumor cell interactions with bone. Thus, Runx2 plays a significant role in the vicious cycle via TGF--induced IHH-PTHrP pathways in breast cancer cells, resulting in increased osteoclastogenesis and osteolysis. Before SPARC cleavage also coincides with an increase in inflammatory cytokines such as IL-6 and IL-8 [51]. It can activate both Smad-dependent and Smad-independent signal pathways to induce preosteolytic factors such as PTHrP [23]. A thorough review of bone remodeling is beyond the scope of this article, and there are several excellent, recent reviews [8, 9]. FOIA 10.1158/0008-5472.CAN-08-1078. 2007, 24: 599-608. 2008, 68: 7795-7802. 2005, 24: 2543-2555. 2. 2009, 11: R56-10.1186/bcr2345. However, both bone degradation and deposition likely occur early in the metastatic process. 10.2353/ajpath.2009.080906. Metastatic breast cancer cells tend to spread to the bones more often than they do to other parts of the body. Eur J Cancer. Marie L, Braik D, Abdel-Razeq N, Abu-Fares H, Al-Thunaibat A, Abdel-Razeq H. Cancer Manag Res. This information is not easily obtained with in vitro studies. At higher doses they may in fact prevent osteoblast differentiation [30]. 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. What initiates remodeling in the non-tumor-containing bone? -, Cell. Several MMPs (MMP2, 3, 9) can release TGF- from the latent state, allowing it to become active. These molecules bind to hydroxyapatite of the bone matrix and are ingested by osteoclasts, which then undergo apoptosis. 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. 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. Estrogen has also been shown to promote osteoclast apoptosis and inhibit activation of mature osteoclasts.

Federal government websites often end in .gov or .mil. Part of this uncertainty is because we do not fully understand all of the cell, cytokine and growth factor interactions that occur in the bone microenvironment. Of the bisphosphonates, zoledronic acid is the most potent. Current therapeutic targets are indicated in green. 2012 Aug;39(8):1174-7. Osteoblasts derive from mesenchymal stem cells in the marrow under control of Runx2, a key osteoblastic transcription factor. Metastatic bone lesions are the predominant malignancy to effect bone, with 15 times the occurrence rate of the next most common bone malignancy. 2003, 300: 957-964. There are 5 tumors notorious for their capacity to spread to bone that include Breast, Lung, Thyroid, Renal Cell and Prostate (a popular memory aid is BLT Kosher Pickle.) Cathepsin K is believed to be the major protease in this capacity. It is now known that PGE2 signaling through its receptor EP4 plays a crucial role in osteolysis by inducing monocytes to form mature osteoclasts. 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. Clin Exp Metastasis. Bone metastasis can occur in any bone but more commonly occurs in the spine, pelvis and thigh. 2010, 9: 122-10.1186/1476-4598-9-122. This feature accounts for the variable sensitivity and specificity of different imaging modalities. The .gov means its official. Cancer Res. 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]. Thus, bone loss is due to both increased activation of osteoclasts and suppression of osteoblasts. Among these are the MMPs. The ratio of RANKL to OPG determines the extent of the osteoclast activity and bone degradation. This approach will allow testing of components and drugs in a model less complex than an animal but more relevant than standard tissue culture. 2010, 70: 1835-1844. 10.1210/en.142.12.5050. Matrix degradation appears to be only one of the roles of MMPs. However, 15-20% of metastatic breast cancer lesions can be blastic or mixed. PubMed Clin Cancer Res. Lipton A: Bone continuum of cancer. Google Scholar. Arch Biochem Biophys. Bone metastasis significantly affects both quality of life and survival of the breast cancer patient. Bone metastases result in lesions or injury to the bone tissue. Induction of aberrant osteoclastogenesis is only part of the equation. Clinical studies of newly diagnosed breast cancer patients have revealed that high bone turnover correlates with a higher risk of skeletal complications [62]. Assessment; Bone; Bone-targeted therapy; Detection; Mechanism of bone metastases; Metastasis; Therapy. When a patient has a metastasis and no site of origin can be found (a metastasis of unknown origin) the most likely site is the lung or kidney. 2010, 48: 483-495. 2010, 126: 1749-1760. Breast cancer had the highest . J Bone Miner Res. 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. PubMed 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 . 2021 Dec 1;31:100407. doi: 10.1016/j.jbo.2021.100407. 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. However, because TGF- plays a more global role in cell proliferation and differentiation, its utility as a therapeutic may be limited. Exp Cell Res. However, PTHrP does not directly stimulate osteoclast differentiation, but rather stimulates other cells to increase RANKL and decrease OPG production. Osteocytes may act as mechanosensing cells and initiate the process when microfractures and loading are involved. 2010, 33 (3 Suppl): S1-7. 2009, 3: 213-218. eCollection 2021 Dec. Nat Rev Cancer. The MMP family, composed of more than 20 members, can collectively degrade all components of the extracelluar 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]. 2007, 6: 2609-2617. Cancer Res. It is common to find increased PTHrP serum levels in breast cancer patients. Bone metastases from breast cancer are typically lytic, meaning that there is area of bone destruction at the site of metastasis. Aldridge SE, Lennard TW, Williams JR, Birch MA: Vascular endothelial growth factor acts as an osteolytic factor in breast cancer metastases to bone. 2010, 70: 6150-6160. The .gov means its official. In a recent comprehensive review article, Lynch [50] presents the case that they are 'master regulators' of the vicious cycle. In the young adult, bone mass reaches its peak, but with increasing age there is a slow loss of mass. VEGF also forms a complex with the extracellular matrix [31, 55]. Clezardin P, Teti A: Bone metastasis: pathogenesis and therapeutic implications. 10.1177/154405910608500703. These types of tumors are called osteolytic, or simply lytic. Proff P, Romer P: The molecular mechanism behind bone remodelling: a review. The mechanisms are thought to be inhibition of tumor cell adhesion as well as osteoclast differentiation. Cells of the monocyte-macrophage lineage are stimulated to form osteoclast progenitor cells. Sanchez-Fernandez MA, Gallois A, Riedl T, Jurdic P, Hoflack B: Osteoclasts control osteoblast chemotaxis via PDGF-BB/PDGF receptor beta signaling. This loss is more precipitous in women, due to the decrease in estrogen at menopause [3]. The cyclooxygenase enzymes COX-1 and COX-2 catalyze the conversion of arachidonic acid to prostaglandins and thromboxanes. Ann N Y Acad Sci. Bone. While EMMPRIN is produced normally during tissue remodeling, it increases during tumor progression and metastasis. 1997, 80 (8 Suppl): 1572-1580. Mol Cancer Ther. Cancer Cell. Other molecules made by multiple myeloma cells, such as IL-3, IL-7 and soluble frizzle-related protein-2, also inhibit osteoblast differentiation [27]. Cancer. Eventually, bone remodeling ceases as both osteoblasts and osteoclasts are lost. Bethesda, MD 20894, Web Policies They follow the osteoclasts, reforming the bone matrix. Because osteoblasts secrete both RANKL and OPG, they are major mediators of osteoclastogenesis [25]. PubMed Central This review summarizes the current understanding of the osteolytic mechanisms of bone metastases, including a discussion of current therapies. Breast cancer metastasis to the bone: mechanisms of bone loss, http://breast-cancer-research.com/series/metastasis_pathway. PGs produced from this arachidonic acid conversion are both autocrine and paracrine factors that help to govern physiologic homeostasis. Bisphosphonates binding to hydroxyapatite are ingested by osteoclasts and cause their apoptosis. Mercer RR, Mastro AM: Cytokines secreted by bone-metastatic breast cancer cells alter the expression pattern of f-actin and reduce focal adhesion plaques in osteoblasts through PI3K. Development of clinically relevant in vivo metastasis models using human bone discs and breast cancer patient-derived xenografts. 10.1097/00003086-200004000-00013. Metastatic cancer cells tend to colonize the heavily vascularized areas of the skeleton, such as the red marrow of the long bones, sternum, pelvis, ribs and vertebrae, where they disrupt not only bone physiology but also hematopoiesis and the immune system [3]. 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.
