Abstract
Breast cancer cells often metastasize to bone. Accumulating evidence suggests that inhibiting the receptor activator of nuclear factor-κB ligand (RANKL) not only leads to reduced bone metastasis of breast cancer but also has antitumoral effects. Here, we used mutant receptor activator of nuclear factor-κB ligand (RANKLM) as a vaccine for active immunization to induce antibodies for immunotherapy of bone metastatic cancer. We investigated whether anti-RANKL antibodies inhibit osteolytic bone metastasis in vitro and in a murine model. MC3T3 cells stimulated by MDA-MB-231 culture medium secreted growth differentiation factor-15 (GDF-15), which induced the nuclear factor-κB signaling cascade. In addition, RANKLM treatment-induced reduction of intraosseous growth of MDA-MB-231 cells correlated with decreased GDF-15 expression, a reduced number of osteolytic lesions, and slower tumor progression. In addition, vaccination with RANKLM led to significant improvement in overall survival and skeletal metastasis in tumor-bearing mice. Induction of anti-RANKL antibodies by RANKLM decreased GDF-15 production by deactivating nuclear factor-κB signaling, which in turn inhibited metastasis of MDA-MB-231 cells to bone. Taken together, the results demonstrate a role for RANKLM immunization in preventing bone metastasis of breast cancer.

ASIAN PAC J TROP MED 2012; 5:91-7. [PMID: 22221748 DOI: 10.1016/s1995-7645(12)60002-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2011] [Revised: 12/15/2011] [Accepted: 01/15/2012] [Indexed: 10/14/2022] Open
Abstract
OBJECTIVE To investigate possible mechanism of toxicarioside A in HS-5 bone stromal cells. METHODS HS-5 bone stromal cells were cultured in media supplemented with various concentrations of toxicarioside A or control DMSO (not treatment). Endoglin and TGF-β were detected by Northern and Western blot analysis and quantified in a standard method. Downstream molecules of endoglin and TGF-β (Smad1, Smad2 and their active phosphorylated counterparts, pSmad1 and pSmad2) were also detected and quantified by Western blot analysis. In addition, cell proliferation assay and small interfering RNA (siRNA) against endoglin were used to certificate the function of endolgin in the HS-5 cells. RESULTS Compared with the not treated (0 μg/mL) or DMSO treated control HS-5 cells, HS-5 cells treated with toxicarioside A were found significant attenuation of endolgin and TGF-β expression. Significant inhibition of cell proliferation was also found in the HS-5 cells treated with toxicarioside A. ALK1-related Smad1 and ALK5-related Smad2 were decreased in HS-5 cells treated with toxicarioside A. In addition, phosphorylated Smad1 (pSmad1) and Smad2 (pSmad2) were also found attenuation in toxicarioside A-treated HS-5 cells. RNA interference showed that blockage of endoglin by siRNA also decreased Smad1 and Smad2 expression in HS-5 cells. CONCLUSIONS Our results indicate that toxicarioside A can influence bone marrow stromal HS-5's function and inhibit HS-5 cell proliferation by alteration of endoglin-related ALK1 (Smad1) and ALK5 (Smad2) signaling.

Abstract
A dynamic interplay between prostate cancer cells and reactive bone stroma modulates growth of metastases within bone. We used microarray analysis to screen for changes in gene expression in bone marrow stromal cells cocultured with prostate cancer cells and found reduced expression of endoglin, a transmembrane glycoprotein that functions as an auxiliary coreceptor for members of the transforming growth factor beta (TGF-beta) family of cytokines. The downstream TGF-beta/bone morphogenetic protein signaling pathway including Smad1 and Smad2/3 also was attenuated, as was Smad-dependent gene transcription. Smad1/5/8-dependent inhibitor of DNA binding 1 expression and Smad2/3-dependent plasminogen activator inhibitor I expression both were decreased and were accompanied by decreased cell proliferation. Small interfering RNA-mediated knockdown of endoglin in HS-5 cells verified that the effects on signaling were a direct result of the attenuation of endoglin. These data illustrate that endoglin acts as a positive regulator of both activin receptor-like kinase 1-induced Smad1/5/8 activation and activin receptor-like kinase 5-induced Smad2/3 activation in bone marrow stromal cells. In addition, the data illustrate that one early event of metastasis upon the arrival of prostate cancer cells into the bone stroma is attenuated endoglin expression in the stromal cells, which subsequently alters Smad signaling and cell proliferation. We hypothesize that coculture of bone marrow stromal cells with prostate cancer cells alters TGF-beta signaling in the stromal cells, ultimately facilitating growth of the cancer cells in the bone compartment. Collectively, these studies suggest that prostate cancer cells modulate TGF-beta responsiveness of bone marrow stroma as one means of facilitating their own growth in bone.

Abstract
Lung cancer often metastasizes to bone in patients with advanced disease. Identification of the factors involved in the interactions between lung cancer cells and bone will improve the prevention and treatment of bone metastases. We identified changes in metastasis-related gene expression of human HARA lung squamous carcinoma cells co-cultured with neonatal mouse calvariae using a pathway-specific microarray analysis. Nine genes were up-regulated and two genes down-regulated in HARA cells co-cultured with mouse calvariae. Five of the nine up-regulated genes, including caveolin 1, CD44, EphB2, ezrin, and Parathyroid hormone-related protein (PTHrP), and one down-regulated gene, SLPI, were further confirmed by Reverse transcription-polymerase chain reaction (RT-PCR). A mouse model was subsequently used to study the role of PTHrP and ezrin in bone metastasis in vivo. PTHrP (all three isoforms) and ezrin were up-regulated in HARA cells at sites of bone metastasis as detected by RT-PCR and immunohistochemistry. The PTHrP 141 mRNA isoform was increased by the greatest extent (13.9-fold) in bone metastases compared to PTHrP 139 and PTHrP 173 mRNA. We then generated a HARA cell line in which PTHrP expression was inducibly silenced by RNA interference. Silencing of PTHrP expression caused significant reduction of submembranous F-actin and decreased HARA cell invasion. Ezrin up-regulation was confirmed by Western blots on HARA cells co-cultured with adult mouse long bones. Further, Transforming growth factor beta (TGF-beta) was identified as one of the factors in the bone microenvironment that was responsible for the up-regulation of ezrin. The identification of PTHrP and ezrin as important regulators of lung cancer bone metastasis offers new mechanistic insights into the metastasis of lung cancer and provides potential targets for the prevention and treatment of lung cancer metastasis.

Abstract
Neuroblastoma is a pediatric tumor that preferentially metastasizes to bone. Patients with bone metastases have a mortality rate >93%, indicating a need for novel treatment targets. Our laboratory has shown that type I insulin-like growth factor receptor (IGF-IR) expression and activation regulate neuroblastoma cell proliferation, motility, invasion, and survival, and that expression of the IGF-IR correlates with neuroblastoma tumorigenicity. Bone expresses large amounts of IGF ligands, and the IGF system is required for normal bone physiology. The current study addresses the role of the IGF system in neuroblastoma metastasis to bone. Upon reaching the bone marrow through the circulation, neuroblastoma cells must dock at the bone marrow endothelium, extravasate into the bone microenvironment, and destroy bone tissue to allow for tumor growth. This report examines the effects of high IGF-IR expression on neuroblastoma cell interaction with bone. The current data show that neuroblastoma cells with high IGF-IR expression, either endogenously or through transfection, adhere to human bone marrow endothelial cells and subsequently migrate toward both IGF-I and human bone stromal cells. High IGF-IR-expressing neuroblastoma cells adhere tightly to bone stromal cells, flatten, and extend processes. When neuroblastoma cells are injected directly into the tibiae of mice, those cells with increased IGF-IR form both osteolytic lesions within the tibiae and secondary tumors within other sites. These results support the hypothesis that IGF-IR expression in neuroblastoma cells increases tumor cell interaction with the bone microenvironment, resulting in greater formation of metastases.

Abstract
The emergence of the molecular triad osteoprotegerin (OPG)/Receptor Activator of NF-kB (RANK)/RANK Ligand (RANKL) has helped elucidate a key signalling pathway between stromal cells and osteoclasts. The interaction between RANK and RANKL plays a critical role in promoting osteoclast differentiation and activation leading to bone resorption. OPG is a soluble decoy receptor for RANKL that blocks osteoclast formation by inhibiting RANKL binding to RANK. The OPG/RANK/RANKL system has been shown to be abnormally regulated in several malignant osteolytic pathologies such as multiple myeloma [MM, where enhanced RANKL expression (directly by tumour cells or indirectly by stromal bone cells or T-lymphocytes)] plays an important role in associated bone destruction. By contrast, production of its endogenous counteracting decoy receptor OPG is either inhibited or too low to compensate for the increase in RANKL production. Therefore, targeting the OPG/RANK/RANKL axis may offer a novel therapeutic approach to malignant osteolytic pathologies. In animal models, OPG or soluble RANK was shown both to control hypercalcaemia of malignancy and the establishment and progression of osteolytic metastases caused by various malignant tumours. To this day, only one phase I study has been performed using a recombinant OPG construct that suppressed bone resorption in patients with multiple myeloma or breast carcinoma with radiologically confirmed bone lesions. RANK-Fc also exhibits promising therapeutic effects, as revealed in animal models of prostate cancer and multiple myeloma. If the animal results translate to similar clinical benefits in humans, using RANK-Fc or OPG may yield novel and potent strategies for treating patients with established or imminent malignant bone diseases and where standard therapeutic regimens have failed.

Abstract
In some carcinomas such as digestive tract carcinomas, bone marrow infiltration by tumor cells is a frequent event but usually remains a micrometastatic disease and rarely induces overt bone lesions. The mechanisms responsible for the control of these metastases in the bone marrow remain poorly known. We show that freshly isolated bone marrow cells from human, murine and rat origin rapidly kill a wide range of syngeneic or xenogeneic carcinoma cell lines in culture. Further analysis of this cytotoxic process in the rat indicated that neither resident bone marrow macrophages nor NK cells were responsible for this cytotoxic effect that was restricted to a subpopulation of bone marrow cells expressing CD90 (Thy-1), a marker of hemopoietic precursors. The tumoricidal activity of these cells did not require long-term culture nor addition of exogenous cytokines or growth factors. A subset of CD90+ cells that rapidly differentiates into CD163(ED2)-expressing macrophages was observed to be responsible for tumor cell killing. These macrophages induced a non-apoptotic death of tumor cells, a process that required both a direct interaction with the tumor cell and nitric oxide (NO) production through the activation of inducible nitric oxide-synthase (iNOS). This ability of pluripotent hemopoietic stem cells to rapidly differentiate into macrophages capable of killing invasive tumor cells may account for the limited expansion of micrometastases of some carcinomas in the bone marrow.

Abstract
Breast and prostate cancer often metastasise to the skeleton. Interestingly, the histopathological characteristics of the bone lesions that arise from these two cancer types differ. Breast tumours give rise to metastases in the skeleton with a mixed lytic/sclerotic pattern, whereas a predominantly sclerotic pattern is seen in metastases from prostate tumours. Osteopontin (OPN) and bone sialoprotein (BSP) are bone matrix proteins that have been implicated in the selective affinity of cancer cells for bone. In the present study, 21 patient cases with skeletal metastasis and their respective primary tumours (12 with breast cancer, 9 with prostate cancer) were investigated by immunohistochemistry in order to assess the level of OPN and BSP. Moderate to strong OPN expression was found in 42% of all breast tumours and in 56% of all prostate tumours. Significantly more breast cancer bone metastases exhibited high OPN expression, 83%, as compared with prostate tumour bone metastases, 11% (P = 0.0019). In contrast, moderate to strong BSP expression was found in 33% of breast tumours and in 89% of prostate tumours. In the bone lesions, only 33% of breast tumour metastases showed moderate/strong BSP expression compared to 100% of prostate tumour metastases (P = 0.0046). This divergent pattern of OPN/BSP expression could be an important determinant for the different characteristics of these two types of bone metastasis, i.e., lytic vs. sclerotic, consistent with the proposed role of OPN in differentiation and activation of osteoclasts and of BSP as a stimulator of bone mineralisation.

Abstract
In human cancers, bone is a common site for metastasis. It is well known that metastasis is the cause of morbidity and mortality in patients with cancer. Both breast and prostate carcinomas have a propensity to metastasize to bone. In general, metastatic breast cancers result in osteolytic lesions. On the other hand, prostate cancer metastases are osteoblastic and result in osteosclerosis. Thus, bone formation and bone resorption are at the crux of the cancer metastasis problem. For example, in the prostate, there is a vicious cycle of metastasis to bone (Fig. 1). Metastases to bone causes excruciating bone pain, pathological fractures, and eventually death, and therefore is a serious challenge to both bone biologists and cancer cell biologists. The stromal-epithelial interactions in breast and prostate are critical in initiation of carcinogenesis and the progression of the metastatic cascade to bone (Fig. 2). Over a hundred years ago, Stephen Paget enunciated the seed and soil hypothesis in which seeds of metastatic cancer cells of breast preferentially settle in the soil of bone matrix. Thus, the prostate/breast cancer bone interface and continuum has continuously presented challenges and opportunities and were discussed at a recent workshop.
