    Abstract Bone disease in multiple myeloma (MM) is characterized by lytic bone lesions, which can cause severe bone pain, pathologic fractures and hypercalcemia. However, the lytic bone disease in MM differs from that in other cancer patients who have lytic bone metastases. Although increased osteoclastic bone destruction is involved in MM and other tumors involving bone, in contrast to other tumors, once the MM tumor burden exceeds 50% in a local area, osteoblast activity is either suppressed or absent. The basis for this severe imbalance between increased osteoclastic bone resorption and decreased bone formation has been a topic of intensive investigation over the last several years and will be reviewed in this article.

    Abstract Multiple myeloma is characterized by extensive bone destruction with little or no new bone formation. A multiplicity of factors including receptor activator NF-kappaB (RANKL), macrophage inflammatory protein-1alpha, interleukin-3 and interleukin-6 can induce osteoclast formation in myeloma and drive the bone destructive process. Furthermore, factors are also produced either in the microenvironment or by myeloma cells themselves, which inhibit osteoblast differentiation and new bone formation. The combination of increased osteoclast formation with little or no bone repair in response to the previous bone destruction explains the severity of the bone disease in myeloma. Studies of the pathophysiology of myeloma bone disease have identified several novel therapeutic targets. These include antibodies to RANKL, chemokine receptor antagonists, which block the effects of chemokines on osteoclast differentiation and proteasome antagonists, which can affect both RANKL production and osteoprotegerin levels as well as inhibit osteoclast and enhance osteoblast differentiation. In addition, many of the new biologic agents being used for the treatment of patients with myeloma also further inhibit the bone destructive process. New therapies that can target both the tumor as well as the severe bone disease should be on the horizon to treat this devastating complication of myeloma.

    Abstract In multiple myeloma (MM), communication via Notch signaling in the tumor niche stimulates tumor progression and bone destruction. We previously showed that osteocytes activate Notch, increase Notch3 expression, and stimulate proliferation in MM cells. We show here that Notch3 inhibition in MM cells reduced MM proliferation, decreased Rankl expression, and abrogated the ability of MM cells to promote osteoclastogenesis. Further, Notch3 inhibition in MM cells partially prevented the Notch activation and increased proliferation induced by osteocytes, demonstrating that Notch3 mediates MM-osteocyte communication. Consistently, pro-proliferative and pro-osteoclastogenic pathways were upregulated in CD138

    Abstract Bone is a frequent site of cancer metastasis. Bone metastases can result in bone destruction or new bone formation. Bone destruction is mediated by factors produced or induced by tumor cells that stimulate formation and activation of osteoclasts, the normal bone-resorbing cells. Local bone destruction also occurs in patients with osteoblastic metastases and may precede or occur simultaneously with increased bone formation. Several factors, including interleukin (IL)-1, IL-6, receptor activator of NF-kappaB (RANK) ligand, parathyroid hormone-related protein (PTHrP), and macrophage inflammatory protein-1-alpha (MIP-1alpha), have been implicated as factors that enhance osteoclast formation and bone destruction in patients with neoplasia. PTHrP seems to be the major factor produced by breast cancer cells that induces osteoclast formation through upregulation of RANK ligand. Enhanced RANK ligand expression also plays an important role in bone destruction in patients with myeloma. RANK ligand can act to enhance the effects of other factors produced by myeloma cells or in response to myeloma cells, such as MIP-1alpha and/or IL-6, to induce osteoclast formation. Understanding of the molecular mechanisms responsible for osteoclast activation in osteolytic metastases should lead to development of novel therapeutic approaches for this highly morbid and potentially fatal complication of cancer.

    Abstract Paget's disease and bone metastases in cancer patients share many common properties. Both are characterized by a localized increase in osteoclast (OCL) formation leading to bone resorption. In both Paget's disease and bone metastases the increased OCL formation and the increased osteoclastogenic nature of the bone microenvironment are mediated by common factors, namely interleukin (IL)-6 and RANK ligand (RANKL). Available data suggest that in the case of Paget's disease there is increased RANKL and IL-6 production, and IL-6 enhances the responsivity of the OCL precursors to RANKL, contributing to the elevated numbers of OCLs. In patients with multiple myeloma, 95% to 100% of whom develop bone lesions, both IL-6 and RANKL levels are increased. Bisphosphonates bind locally to the surfaces of the bone undergoing osteoclastic resorption to inhibit this process. Paget's disease has in the past and will continue in the future to provide a model to test the efficacy of bisphosphonates in inhibiting bone resorption. Paget's disease provides an ideal model in which to investigate the efficacy of the new third-generation bisphosphonates in the treatment of bone metastases as well as nonmalignant bone disease.

    Abstract The osteoclast is a hematopoietic cell derived from CFU-GM and branches from the monocyte-macrophage lineage early during the differentiation process. The marrow microenvironment appears critical for osteoclast formation due to production of RANK ligand, a recently described osteoclast differentiation factor, by marrow stromal cells in response to a variety of osteotropic factors. In addition, factors such as osteoprotegerin, a newly described inhibitor of osteoclast formation, as well as secretory products produced by the osteoclast itself and other cells in the marrow enhance or inhibit osteoclast formation. The identification of the role of oncogenes such as c-fos and pp60 c-src in osteoclast differentiation and bone resorption have provided important insights in the regulation of normal osteoclast activity. Current research is beginning to delineate the signaling pathways involved in osteoclastic bone resorption and osteoclast formation in response to cytokines and hormones. The recent development of osteoclast cell lines may make it possible for major advances to our understanding of the biology of the osteoclast to be realized in the near future.

    Abstract We report that transgenic mice expressing measles virus nucleocapsid protein (MVNP) in osteoclasts (OCLs) (MVNP mice) are Paget's disease (PD) models and that OCLs from patients with PD and MVNP mice express high levels of OCL-derived IGF1 (OCL-IGF1). To determine OCL-IGF1's role in PD and normal bone remodeling, we generated WT and MVNP mice with targeted deletion of Igf1 in OCLs (Igf1-cKO) and MVNP/Igf1-cKO mice, and we assessed OCL-IGF1's effects on bone mass, bone formation rate, EphB2/EphB4 expression on OCLs and osteoblasts (OBs), and pagetic bone lesions (PDLs). A total of 40% of MVNP mice, but no MVNP/Igf1-cKO mice, had PDLs. Bone volume/tissue volume (BV/TV) was decreased by 60% in lumbar vertebrae and femurs of MVNP/Igf1-cKO versus MVNP mice with PDLs and by 45% versus all MVNP mice tested. Bone formation rates were decreased 50% in Igf1-cKO and MVNP/Igf1-cKO mice versus WT and MVNP mice. MVNP mice had increased EphB2 and EphB4 levels in OCLs/OBs versus WT and MVNP/Igf1-cKO, with none detectable in OCLs/OBs of Igf1-cKO mice. Mechanistically, IL-6 induced the increased OCL-IGF1 in MVNP mice. These results suggest that high OCL-IGF1 levels increase bone formation and PDLs in PD by enhancing EphB2/EphB4 expression in vivo and suggest OCL-IGF1 may contribute to normal bone remodeling.
