Their multifunctionality demonstrates their importance. COX-2 activity in breast cancer cells has also been found to modulate the expression and activity of MMPs. 10.1038/sj.bjc.6601437. Assessment; Bone; Bone-targeted therapy; Detection; Mechanism of bone metastases; Metastasis; Therapy. (A) The bone remodeling unit consists of osteoblasts, which produce osteoid, bone matrix, and osteoclasts, which degrade mineralized bone. Exp Oncol. Careers. official website and that any information you provide is encrypted Bone metastasis can occur in any bone but more commonly occurs in the spine, pelvis and thigh. 2003, 38: 605-614. 2023 BioMed Central Ltd unless otherwise stated. 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. 2005, 92: 1531-1537. While EMMPRIN is produced normally during tissue remodeling, it increases during tumor progression and metastasis. Myeloma cells may also produce RANKL and directly affect osteoclasts [28]. The https:// ensures that you are connecting to the In males, prostate and lung cancers make up 80% of carcinomas metastasising to bone.

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. 2022 Aug 23;14:2519-2531. doi: 10.2147/CMAR.S369910. Thus, bone loss is due to both increased activation of osteoclasts and suppression of osteoblasts. 10.1111/j.0105-2896.2005.00326.x. MMP-9 is important in the cascade leading to activation of VEGFA. It's not the same as having cancer that starts in the bone. 2007, 67: 9542-9548. In males, prostate and lung cancers make up 80% of carcinomas metastasizing to bone. Increased production of EMMPRIN in turn leads to increases in VEGF and MMPs. In doing so, cancer cells are equipped to home, adhere, survive and proliferate in the bone microenvironment. 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. 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. At the tissue level, PDGF is involved in bone formation, wound healing, erythropoiesis and angiogenesis as well as tumor growth and lesion development [57]. However, once bone metastasis has occurred, the aim has been to break the osteolytic cycle by targeting osteoclasts. While the case for the importance of MMPs as metastasis regulators is strong, they themselves are regulated by tissue inhibitors of metalloproteinase (TIMPs). In the young adult, bone mass reaches its peak, but with increasing age there is a slow loss of mass. Br J Cancer. 2010, 3: 572-599. In summary, all of these factors contribute to propagating the vicious cycle and increasing osteolysis (Figure 1B). Ganapathy and colleagues [24] found that TGF- antagonists are able to reduce bone metastasis and the number and activity of differentiated osteoclasts [24]. 2010, 115: 140-149. Bone metastasis can cause pain and broken bones. 1970, 86: 1436-1440. Article The mechanisms for suppressed osteoblast activity are not clear but Dickkopf-1 (DKK1), an inhibitor of Wnt signaling, is believed to inhibit osteoblast differentiation [29]. 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]. 10.1158/0008-5472.CAN-10-2179. Cancer Res. Clarke BL, Khosla S: Physiology of bone loss. It can activate both Smad-dependent and Smad-independent signal pathways to induce preosteolytic factors such as PTHrP [23]. 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. In the context of the current discussion, cancer cells may initiate the process. Metastatic breast cancer (also called stage IV or advanced breast cancer) is not a specific type of breast cancer. 2010, 363: 2458-2459. 2008, 3: e3537-10.1371/journal.pone.0003537. 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 . Epub 2021 Oct 5. Orr and colleagues [5] have determined MMPs sufficient to resorb bone in vitro and to contribute to the process in vivo. Bone. Breast cancer is often compared with prostate cancer, which metastasizes to the skeleton with a similar frequency. Google Scholar.

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. Osteoblasts and bone stromal cells can respond to a variety of substances that upregulate RANKL. Google Scholar, Mundy GR: Bone Remodeling and its Disorders. Bone metastasis significantly affects both quality of life and survival of the breast cancer patient. 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. 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. Would you like email updates of new search results? 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. TGF- is well-known for its role in osteolytic bone metastasis. 2006, 85: 584-595. 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. Angiogenesis inhibitor TNP-470 inhibits human breast cancer osteolytic bone metastasis in nude mice through the reduction of bone resorption. 2010, 29: 811-821. It is a reservoir of numerous growth factors as well as calcium and phosphorous, which are released from the matrix during bone remodeling. Breast cancer had the highest . It can activate osteoclasts independent of RANKL [21]. 10.1210/endo-86-6-1436. Brook N, Brook E, Dharmarajan A, Dass CR, Chan A. Int J Biochem Cell Biol. Bone metastasis significantly affects both quality of life and survival of the breast cancer patient. They follow the osteoclasts, reforming the bone matrix. Cholesterol Synthesis Is Important for Breast Cancer Cell Tumor Sphere Formation and Invasion. Ooi LL, Zheng Y, Stalgis-Bilinski K, Dunstan CR: The bone remodeling environment is a factor in breast cancer bone metastasis. -, Science. Wang Y, Nishida S, Elalieh HZ, Long RK, Halloran BP, Bikle DD: Role of IGF-I signaling in regulating osteoclastogenesis. The presence of tumor cells in the bone microenvironment perturbs the balance between osteoblasts and osteoclasts, leading to excess bone loss or formation. Thus, the ratio of RANKL to OPG is critical for osteoclast activation. It is now known that PGE2 signaling through its receptor EP4 plays a crucial role in osteolysis by inducing monocytes to form mature osteoclasts. Before Brown JE, Thomson CS, Ellis SP, Gutcher SA, Purohit OP, Coleman RE: Bone resorption predicts for skeletal complications in metastatic bone disease. Cytokines such as IL-6, IL-8 and IL-11 secreted by breast cancer cells also promote osteoclast differentiation and bone resorption. Cancer Treat Rev. The other 20% of primary disease sites in both sexes are: kidney, thyroid, gastrointestinal tract and other locations. Hadjidakis DJ, Androulakis II: Bone remodeling. 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.

Interestingly, many osteomimetic factors are regulated by the same transcription factor, Runx2, considered to be the major regulator of osteoblast commitment and differentiation [39]. 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. Myeloma cells produce factors that upregulate osteoblast production of M-CSF and RANKL and downregulate production of OPG. The .gov means its official. CAS In addition, production of inflammatory cytokines (that is, IL-6, TNF-, M-CSF, IL-1) is suppressed by estrogen [64]. Neutralization of TGF- in conditioned medium from human metastatic MDA-MB-231 breast cancer cells permitted the differentiation of osteoblasts in culture, suggesting that TGF- negatively affects osteoblasts while promoting growth of the metastatic cells [33]. 10.1097/COC.0b013e3181deb9e5. At least three major growth factors sequestered in the matrix are activated by MMPs. The receptor binding activity in turn causes an increase in production of RANKL. Commonly used modalities include local therapies such as surgery, radiation therapy and radiofrequency ablation (RFA) together with systemic therapies such as endocrine therapy, chemotherapy, monoclonal antibody-based therapy, bone-enhancing therapy and radioisotope therapy. These results signify an important role for cancer cell-derived Runx2 in the osteolytic process. Metastases leading to overall bone loss are classified as osteolytic. 10.1158/0008-5472.CAN-08-1078.

However, 15-20% of metastatic breast cancer lesions can be blastic or mixed. These drugs may also cause cancer cell death; however, they may also negatively affect osteoblasts. It is interesting that cancer cells often remain dormant in bone for many years before they begin to grow. PubMed Central Recently, we have found that metastatic breast cancer cells have profound effects on osteoblasts in culture [22] and in animals [31, 32]. 1988 Jun;7(2):143-88 Cancer Cell. Google Scholar. MeSH However, breast cancer cells are unable to progress in bone unless they destroy bone with the assistance of bone-resorbing osteoclasts. Cathepsin K is the major mediator of bone resorption, controlling the osteoclast portion of the vicious cycle. PGs produced from this arachidonic acid conversion are both autocrine and paracrine factors that help to govern physiologic homeostasis. FOIA It is common to find increased PTHrP serum levels in breast cancer patients. Eventually, bone remodeling ceases as both osteoblasts and osteoclasts are lost. Understanding the mechanisms of osteolysis should be the key to designing the cure. Klein DC, Raisz LG: Prostaglandins: stimulation of bone resorption in tissue culture. Rucci N, Teti A: Osteomimicry: how tumor cells try to deceive the 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]. sharing sensitive information, make sure youre on a federal In the final stages of metastatic osteolytic breast cancer disease, the cancer cells, fueled by growth factors released from the degraded matrix, expand unchecked. When the bone loss is extensive, the osteoblasts are absent from the lesion [32]. 1997, 80 (8 Suppl): 1546-1556. 2010, 36: 615-620. Coleman R, Gnant M: New results from the use of bisphosphonates in cancer patients. Induction of aberrant osteoclastogenesis is only part of the equation. While ductal carcinoma in situ detected early is 98% curable, bone metastases are basically incurable [2]. Several of these RANKL inducers merit further discussion with respect to metastatic breast cancer-induced osteolysis.

Sanchez-Fernandez MA, Gallois A, Riedl T, Jurdic P, Hoflack B: Osteoclasts control osteoblast chemotaxis via PDGF-BB/PDGF receptor beta signaling. 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]. 2010, [Epub ahead of print]. In addition, other cells not specific for bone but likely to be found in the bone (macrophages, neutrophils and T lymphocytes) produce MMPs. 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. Annu Rev Pathol. Even in adults it is estimated that about 10% of the bone is renewed each year [7]. 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. 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. 10.1016/j.yexcr.2007.09.021. 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. Metastasis of breast cancer cells to bone consists of multiple sequential steps. Front Biosci (Schol Ed). Bone metastases in breast cancer may be osteolytic, osteoblastic, or mixed blastic and lytic. Clipboard, Search History, and several other advanced features are temporarily unavailable. blastic (bone formation), or mixed lesions (Fig 2). Clin Pharmacol Ther. 2009, 69: 4097-4100. Cells of the osteoblast lineage are derived from mesenchymal stem cells, and are represented in this unit by osteoblasts, bone lining cells and osteocytes. They also are regulators of other molecules important in the vicious cycle. 10.1097/00003086-200004000-00013. Guise TA, Mundy GR: Cancer and bone. These cells fuse to form multinucleated, but non-functional pre-osteoclasts. However, the presence of metastatic breast cancer cells or other bone metastatic cancers, such as prostate, lung, renal, and myeloma, accelerates the remodeling process and disturbs the balance between bone depositing cells, osteoblasts, and bone degrading cells, osteoclasts. By using this website, you agree to our PubMed 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]. Corisdeo S, Gyda M, Zaidi M, Moonga BS, Troen BR: New insights into the regulation of cathepsin K gene expression by osteoprotegerin ligand. Denosumab is an antibody directed to RANKL that prevents osteoclast differentiation. Clinically, complications secondary to bone metastasis include pain, pathologic fractures, spinal cord compression, and hypercalcemia of malignancy. Meanwhile, COX-2 produced by breast cancer cells and osteoblasts increases the localized PGE2 concentration, which can directly bind to osteoblasts, promoting RANKL expression and further stimulating osteoclast differentiation. 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. Bone. Int J Cancer. PTH/PTHrP, TNF-, prostaglandins (PGE2), IL-1, IL-11, FGF-2, and IGF-1 have been reported to increase RANKL production. 2009, 11: R56-10.1186/bcr2345. Clin Exp Metastasis.

However, both drugs are associated with low incidence of osteonecrosis of the jaw [75]. 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. 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. Smolle MA, Musser E, Bergovec M, Friesenbichler J, Wibmer CL, Leitner L, Srensen MS, Petersen MM, Brcic I, Szkandera J, Scheipl S, Leithner A. The tumors that develop, sometimes called lesions, can: Make the bones weaker and less dense. The resorption phase of the process begins with recruitment of pre-osteoclasts that differentiate into activated osteoclasts under the direction of osteoblasts (Figure 1A). These functional molecules complete the cycle and osteolysis continues. Troen BR: Molecular mechanisms underlying osteoclast formation and activation. sharing sensitive information, make sure youre on a federal 10.1038/sj.emboj.7600729. Administration of bisphosphonates may slow osteolytic lesion progression and stabilize or increase overall bone density, but does not bring about healing [1, 16, 26]. In the late 1980 s, PTHrP was linked to hypercalcemia in several cancers, providing evidence that PTHrP was involved in bone resorption. Osteomimetic factors driven by abnormal Runx2 activation in breast cancer cells may increase their survival in the bone microenvironment. Evolving cancer-niche interactions and therapeutic targets during bone metastasis. Metastases leading to overall bone loss are classified as osteolytic. eCollection 2022. Often, bone metastases have both lytic and blastic features. 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]. Lung cancer is the third most common site of origin of metastatic cancer deposits in bone, after breast and prostate cancer. Denosumab (Prolia), the latest drug to enter the field, is a monoclonal antibody to RANKL.
