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]. Bone is the most common site of metastasis for breast cancer. Exp Cell Res. 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 . The tumors that develop, sometimes called lesions, can: Make the bones weaker and less dense. These capacities are essential for any cancer cells to develop distant metastases in organs such as lungs and liver as well as bone. This loss is more precipitous in women, due to the decrease in estrogen at menopause [3]. The purpose of this study is to find a safe dose of: - Xentuzumab in combination with abemaciclib - Xentuzumab in combination with abemaciclib and hormonal therapies The study also tests whether these medicines make tumours shrink in participants with lung and breast cancer. Abstract Metastasis of breast cancer cells to bone consists of multiple sequential steps. 2010, 9: 122-10.1186/1476-4598-9-122. The receptor binding activity in turn causes an increase in production of RANKL.

Along with colleagues and students she has focused particularly on the fate of osteoblasts in the metastatic bone environment. 2022 Dec 2;11(12):2394. doi: 10.3390/antiox11122394. 2007, 6: 2609-2617. 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]. 10.1007/s10911-005-5399-8. For example, OPN is produced by many breast cancer cells and has a strong clinical correlation with poor prognosis and decreased survival [37]. Estrogen profoundly affects bone remodeling by suppressing production of RANKL while increasing production of OPG. Purpose: This is a study in adult patients with different types of cancer. 2007, 67: 9542-9548. Cells of the immune system, T cells and dendritic cells can also express RANKL. spinal cord compression) palpable mass deformity pathological fracture hypercalcemia bone marrow aplasia Here we discuss some of the proposed mechanisms that contribute to metastatic breast cancer-induced bone loss. 10.1097/COC.0b013e3181deb9e5. 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.

Further stimulation results in large multinuclear cells capable of bone resorption. Lerner UH: Bone remodeling in post-menopausal osteoporosis. However, the process is described in brief in order to further consider the mechanisms of osteolytic metastasis. eCollection 2022. Recently, Roy and colleagues [69] investigated this association in a mouse model of autoimmune arthritis and found that arthritic mice had an increase in both lung and bone metastasis compared to the non-arthritic mice.

Karaplis AC, Goltzman D: PTH and PTHrP effects on the skeleton. There is evidence in both humans and animals that bone loss in osteolytic metastasis is partly due to the failure of the osteoblasts to produce new osteoid for the bone matrix. Even in adults it is estimated that about 10% of the bone is renewed each year [7]. Metastases leading to overall bone loss are classified as osteolytic. (A) The bone remodeling unit consists of osteoblasts, which produce osteoid, bone matrix, and osteoclasts, which degrade mineralized bone. Tian E, Zhan F, Walker R, Rasmussen E, Ma Y, Barlogie B, Shaughnessy JD: The role of the Wnt-signaling antagonist DKK1 in the development of osteolytic lesions in multiple myeloma. These molecules cause osteoblasts not only to form new bone but also to release RANKL and other osteoclastic mediators. However, both bone degradation and deposition likely occur early in the metastatic process. 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. 2003, 3: 537-549. Administration of bisphosphonates may slow osteolytic lesion progression and stabilize or increase overall bone density, but does not bring about healing [1, 16, 26]. Google Scholar. J Dent Res. While not directly responsible for osteolysis in metastatic breast cancer disease, there are physiological parameters that can amplify the degree of bone loss. 10.1007/s10585-007-9112-8. MMP-9 is important in the cascade leading to activation of VEGFA. 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. 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. In doing so, cancer cells are equipped to home, adhere, survive and proliferate in the bone microenvironment. 10.1210/endo-86-6-1436. 2008, Washington, DC: American Society for Bone and Mineral Research, 374-378. full_text. COX-2 activity in breast cancer cells has also been found to modulate the expression and activity of MMPs.

On x-rays, these metastases show up as spots that are whiter than the bone around them. 2. -, Science. 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. Google Scholar. Where do the MMPs come from? Google Scholar. -, Cell. Bone. 10.1038/sj.bjc.6602417. Due to this, the bones get harder and cause the condition called sclerosis. PubMed Central 10.1016/S8756-3282(03)00086-3. Marie PJ: Transcription factors controlling osteoblastogenesis. Clinically, complications secondary to bone metastasis include pain, pathologic fractures, spinal cord compression, and hypercalcemia of malignancy. 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. Please enable it to take advantage of the complete set of features! Oncogene. The mechanisms are thought to be inhibition of tumor cell adhesion as well as osteoclast differentiation. 2009, 69: 4097-4100. 10.1007/s10585-006-9044-8. Hillner BE, Ingle JN, Berenson JR, Janjan NA, Albain KS, Lipton A, Yee G, Biermann JS, Chlebowski RT, Pfister DG. However, PTHrP does not directly stimulate osteoclast differentiation, but rather stimulates other cells to increase RANKL and decrease OPG production. These results signify an important role for cancer cell-derived Runx2 in the osteolytic process. It improves the quality of life by preventing fractures but does not prolong life [73]. Bone lining cells appear microscopically as relatively undifferentiated cells that line the bone. DMS is a senior research technician with many years experience in the bone field. 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]. Osteomimetic factors include osteopontin (OPN), osteocalcin, osteonectin, bone sialoprotein, RANKL and PTHrP. Several of these RANKL inducers merit further discussion with respect to metastatic breast cancer-induced osteolysis. 10.1016/S1535-6108(03)00132-6. For females, breast and lung are the most common primary sites ; nearly 80% of cancers that spread to the skeleton are from these locations. 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]. There is evidence that osteoblastic metastases form at sites of osteolytic lesions, suggesting an overall increase of bone remodeling Accelerated osteoblastogenesis can be stimulated by factors secreted by prostate cancer cells, such as endothelin-1, TGF-, and fibroblast growth factor (FGF) [1]. 2000, 2: 737-744. IGF binding proteins keep this molecule latent.

These functional molecules complete the cycle and osteolysis continues. Takahashi T, Uehara H, Bando Y, Izumi K: Soluble EP2 neutralizes prostaglandin E2-induced cell signaling and inhibits osteolytic tumor growth. 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]. -, Cancer Metastasis Rev. However, teriparatide is associated with an increased risk of osteosarcoma and exacerbation of skeletal metastases because of its effect on bone turnover [75].

J Biomol Tech. In contrast to breast cancer, prostate bone metastasis often results in osteoblastic lesions. In the late 1980 s, PTHrP was linked to hypercalcemia in several cancers, providing evidence that PTHrP was involved in bone resorption. 8600 Rockville Pike Primer on the Metabolic Bone Diseases and Disorders of Mineral Metabolism. At least three essential molecules, TGF-, IGF, and VEGF, need to be activated by MMPs before they can function. For example, a hydroxyapatite scaold pre-loaded with bone morphogenetic protein-2 enhanced the growth rate of mammary tumor cells in the scaold [77]. Exp Oncol. Epidemiological studies have also correlated the increase in breast cancer rates with decreasing sunlight exposure. Below are the links to the authors original submitted files for images. This information is not easily obtained with in vitro studies. Bone metastases result in lesions or injury to the bone tissue. 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. Breast, prostate, and lung cancers represent the main sources of bone metastases, with prostate and lung cancers being most common in males and breast cancer being most common in females . Bone metastasis can cause pain and broken bones. Osteoclasts derive from hematopoietic stem cells. 2003, 89: 2031-2037. 10.1177/154405910608500703. Bone remodeling is often described as a cycle beginning with bone degradation and ending with bone deposition (Figure 1A). Kang and colleagues [20] found that expression of two MMP genes, MMP1 and ADAMTS1, discriminated between a subline of osteotropic metastatic MDA-MB-231 cells and the parental line.

We also discuss known risk factors as well as detection and assessment of bone metastases. At higher doses they may in fact prevent osteoblast differentiation [30]. While the case for the importance of MMPs as metastasis regulators is strong, they themselves are regulated by tissue inhibitors of metalloproteinase (TIMPs). 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.) Cancer cells, osteoblasts, osteoclasts and endothelial cells produce MMPs. 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. Bone metastases in breast cancer may be osteolytic, osteoblastic, or mixed blastic and lytic. TGF- is well-known for its role in osteolytic bone metastasis. Arch Biochem Biophys. 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. Primer on the Metabolic Bone Diseases and Disorders of Mineral Metabolism. 2010, 115: 140-149. 2007, 57: 43-66. CAS VEGF also forms a complex with the extracellular matrix [31, 55]. Cathepsin K is the major mediator of bone resorption, controlling the osteoclast portion of the vicious cycle. 10.1023/A:1026526703898. The site is secure. In males, prostate and lung cancers make up 80% of carcinomas metastasising to bone.

The other 20% of primary disease sites in both sexes are: kidney, thyroid, gastrointestinal tract and other locations. 2010, 33 (3 Suppl): S1-7. The resorption phase of the process begins with recruitment of pre-osteoclasts that differentiate into activated osteoclasts under the direction of osteoblasts (Figure 1A). The lesions can often be blastic but may also appear purely lytic, with poor margination, no matrix and cortical destruction. More than half of people who develop stage IV breast cancer have bone metastasis. 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. Guise TA, Mundy GR: Cancer and bone. 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. 10.1182/blood-2009-08-237628. Breast cancer frequently metastasizes to the skeleton. Several of these molecules are related to the recruitment and differentiation of osteoclasts; some are prominent players in the vicious cycle. PDGF is a dimeric protein consisting of two of four possible subunits. 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. Clin Cancer Res. 1991 Apr 1;47(6):922-8 10.1111/j.0105-2896.2005.00326.x. 2010, 36: 615-620. 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. Article Cell Tissue Res. Cancer Treat Rev. Thus, inflammation is likely to be important in cancer initiation, metastasis and the resulting osteolysis. Breast Cancer Research RANKL and other pro-osteoclastogenic cytokines are increased with a concomitant reduction in OPG, resulting in more osteoclast formation and bone degradation. Bone. 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]. Klein DC, Raisz LG: Prostaglandins: stimulation of bone resorption in tissue culture. 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]. 10.1158/0008-5472.CAN-09-2758. 7, Chapter PubMed 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. 10.1016/j.ctrv.2010.04.003. 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].

Survival Prediction in Patients Treated Surgically for Metastases of the Appendicular Skeleton-An External Validation of 2013-SPRING Model. Evidence from an intratibial bone metastasis model indicates that when highly aggressive metastatic MDA-MB-231 cells express dysfunctional Runx2 or small hair-pin RNA for Runx2, both osteoclastogenesis and osteolytic lesions decrease [40]. Lytic lesions are caused by cancer cells causing old bone to break down without new bone being . These molecules bind to hydroxyapatite of the bone matrix and are ingested by osteoclasts, which then undergo apoptosis. IGF binding initiates production of M-CSF and RANKL by osteoblasts and c-fms and RANK by osteoclasts [54]. However, both bone degradation and deposition likely occur early in the metastatic process. HHS Vulnerability Disclosure, Help Doctors use imaging tests, such as x-rays, to figure out the types of . eCollection 2022 Dec. Edwards CM, Clements ME, Vecchi LA 3rd, Johnson JA, Johnson RW. 10.1158/1078-0432.CCR-05-1806. This increase in COX-2 results in increased secretion of PGE2, which binds to EP4 receptors on the surface of the osteoblasts. 10.1158/0008-5472.CAN-09-3194. As might be expected from the nature of the osteolytic process, that is, the degradation of bone, the microenvironment contains many proteases. Osteocytes are terminally differentiated osteoblasts that become embedded in the bone matrix at the end of the deposition phase of remodeling. This approach will allow testing of components and drugs in a model less complex than an animal but more relevant than standard tissue culture. Other molecules made by multiple myeloma cells, such as IL-3, IL-7 and soluble frizzle-related protein-2, also inhibit osteoblast differentiation [27]. Metastases leading to overall bone loss are classified as osteolytic. 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. 2010, 126: 1749-1760. 2010, 70: 8329-8338. Wang Y, Nishida S, Elalieh HZ, Long RK, Halloran BP, Bikle DD: Role of IGF-I signaling in regulating osteoclastogenesis. Those leading to excess bone deposition are considered osteoblastic. 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. N Engl J Med. Cancer Treat Rev. Denosumab has recently been approved by the FDA for treatment of osteoporosis in women with high risk of fractures and is being considered for treatment of bone metastasis. They follow the osteoclasts, reforming the bone matrix. Studies with MMP9-null mice indicate its importance in tumor progression in ovarian cancer, prostate cancer and bone metastasis [56].

Article 1998, 19: 18-54. 2001, 142: 5050-5055. However, because TGF- plays a more global role in cell proliferation and differentiation, its utility as a therapeutic may be limited. Bone is the most common site of metastasis for breast cancer. Denosumab is an antibody directed to RANKL that prevents osteoclast differentiation. A newly discovered molecule downstream of RANKL is extracellular matrix metalloproteinase inducer (EMMPRIN)/CD147, a cell surface glycoprotein that is known to induce MMPs and VEGF [48]. Larkins TL, Nowell M, Singh S, Sanford GL: Inhibition of cyclooxygenase-2 decreases breast cancer cell motility, invasion and matrix metalloproteinase expression. -, Proc Natl Acad Sci U S A. 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.

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. The MMP family, composed of more than 20 members, can collectively degrade all components of the extracelluar matrix. 2022 Aug 6;10(8):1908. doi: 10.3390/biomedicines10081908. Development of clinically relevant in vivo metastasis models using human bone discs and breast cancer patient-derived xenografts. Cathepsin K is believed to be the major protease in this capacity. Osteoblasts derive from mesenchymal stem cells in the marrow under control of Runx2, a key osteoblastic transcription factor. PTH/PTHrP, TNF-, prostaglandins (PGE2), IL-1, IL-11, FGF-2, and IGF-1 have been reported to increase RANKL production. Accessibility While ductal carcinoma in situ detected early is 98% curable, bone metastases are basically incurable [2]. Prostate. For females, breast and lung are the most common primary sites ; nearly 80% of cancers that spread to the skeleton are from these locations. 2004, 26: 179-184. 2006, 1092: 385-396. Clin Breast Cancer. The average survival after the diagnosis of a breast cancer metastasis to bone has dramatically . Cytokines such as IL-6, IL-8 and IL-11 secreted by breast cancer cells also promote osteoclast differentiation and bone resorption. Breast cancer-derived factors facilitate osteolytic bone metastasis. 2008, 34 (Suppl 1): S25-30. Heterogeneity of tumor cells in the bone microenvironment: Mechanisms and therapeutic targets for bone metastasis of prostate or breast cancer. 2010, 2: 907-915. In advanced disease, bone formation is essentially absent, and the processes of bone resorption and formation become uncoupled. IL-8, a proinflammatory CXC chemokine, is secreted by monocytes, endothelial cells and osteoblasts. This area has been likened to an extracellular lysosome [11]. However, this approach has not entirely solved the problem. According to this paradigm, the tumor cells produce a variety of growth factors, most notably parathyroid hormone-related protein (PTHrP) [18]. Google Scholar. For example, the use of aromatase inhibitors increases the risk for osteoporosis. Clin Adv Hematol Oncol. 2021 Dec 1;31:100407. doi: 10.1016/j.jbo.2021.100407. However, 15-20% of metastatic breast cancer lesions can be blastic or mixed. While EMMPRIN is produced normally during tissue remodeling, it increases during tumor progression and metastasis. It binds to two class III tyrosine kinase receptors, PDGFR and PDGFR, leading to activation of several signaling molecules. 2009, 15: 5829-5839. There are many suspected factors, such as microfractures, loss of mechanical loading, hormones, cytokines, calcium levels and inflammation. Proff P, Romer P: The molecular mechanism behind bone remodelling: a review. 10.1158/0008-5472.CAN-08-1078. The majority of breast cancer metastases ultimately cause bone loss.

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. Of course, the best cure for bone metastasis is prevention. Thus, in the course of the osteolytic process, the osteoblasts are unable to fulfill their role as bone building cells. The presence of metastatic lesions in bone disrupts the normal bone microenvironment and upsets the fine balance between the key components. Myeloma cells may also produce RANKL and directly affect osteoclasts [28]. Lipton A: Emerging role of bisphosphonates in the clinic--antitumor activity and prevention of metastasis to bone. It is required to drive mesenchymal cells to become osteoblasts. Please enable it to take advantage of the complete set of features! Biochem Biophys Res Commun. However, more accessible and defined [76] models are needed. Clinical Characteristics, Prognostic Factors and Treatment Outcomes of Patients with Bone-Only Metastatic Breast Cancer. This site needs JavaScript to work properly. 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. As seen in the images here, multiple, confluent sclerotic, blastic bony lesions are typical of metastatic breast cancer. 1993 Jun 1;90(11):5021-5 Cackowski FC, Anderson JL, Patrene KD, Choksi RJ, Shapiro SD, Windle JJ, Blair HC, Roodman GD: Osteoclasts are important for bone angiogenesis. 10.1016/j.yexcr.2005.07.029. EMBO J. These approaches still rely on animals. 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. 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. , Uehara H, Bando Y, Izumi K: Soluble EP2 neutralizes prostaglandin E2-induced cell signaling and osteolytic..., TNF-, prostaglandins ( PGE2 ), IL-1, IL-11, FGF-2 and!, Clements ME, Vecchi LA 3rd, Johnson RW initiation, metastasis and the processes of bone....
