Abstract
Every day we march closer to finding the cure for multiple myeloma. The myeloma cells inflict their damage through specialized cellular meshwork and cytokines system. Implicit in these interactions are cellular adhesion molecules and their regulators which include but are not limited to integrins and syndecan-1/CD138, immunoglobulin superfamily cell adhesion molecules, such as CD44, cadherins such as N-cadherin, and selectins, such as E-selectin. Several adhesion molecules are respectively involved in myelomagenesis such as in the transition from the precursor disorder monoclonal gammopathy of undetermined significance to indolent asymptomatic multiple myeloma (smoldering myeloma) then to active multiple myeloma or primary plasma cell leukemia, and in the pathological manifestations of multiple myeloma.

Desmoglein-2 expression is an independent predictor of poor prognosis patients with multiple myeloma. Mol Oncol 2021; 16:1221-1240. [PMID: 34245117 PMCID: PMC8936512 DOI: 10.1002/1878-0261.13055] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2021] [Accepted: 07/09/2021] [Indexed: 12/20/2022] Open
Abstract
Multiple myeloma (MM) is the second most common haematological malignancy and is an incurable disease of neoplastic plasma cells (PC). Newly diagnosed MM patients currently undergo lengthy genetic testing to match chromosomal mutations with the most potent drug/s to decelerate disease progression. With only 17% of MM patients surviving 10‐years postdiagnosis, faster detection and earlier intervention would unequivocally improve outcomes. Here, we show that the cell surface protein desmoglein‐2 (DSG2) is overexpressed in ~ 20% of bone marrow biopsies from newly diagnosed MM patients. Importantly, DSG2 expression was strongly predictive of poor clinical outcome, with patients expressing DSG2 above the 70th percentile exhibiting an almost 3‐fold increased risk of death. As a prognostic factor, DSG2 is independent of genetic subtype as well as the routinely measured biomarkers of MM activity (e.g. paraprotein). Functional studies revealed a nonredundant role for DSG2 in adhesion of MM PC to endothelial cells. Together, our studies suggest DSG2 to be a potential cell surface biomarker that can be readily detected by flow cytometry to rapidly predict disease trajectory at the time of diagnosis.

Cancers (Basel) 2020; 12:cancers12123643. [PMID: 33291672 PMCID: PMC7761917 DOI: 10.3390/cancers12123643] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2020] [Revised: 12/02/2020] [Accepted: 12/02/2020] [Indexed: 02/07/2023] Open
Abstract
Simple Summary Like in solid cancers, the process of dissemination is a critical feature of disease progression in the blood cancer multiple myeloma. At diagnosis, myeloma patients have cancer that has spread throughout the bone marrow, with patients with more disseminatory myeloma having worse outcomes for their disease. In this review, we discuss the current understanding of the mechanisms that underpin the dissemination process in multiple myeloma. Furthermore, we discuss the potential for the use of therapies that target the dissemination process as a novel means of improving outcomes for multiple myeloma patients. Abstract Multiple myeloma (MM) is a plasma cell (PC) malignancy characterised by the presence of MM PCs at multiple sites throughout the bone marrow. Increased numbers of peripheral blood MM PCs are associated with rapid disease progression, shorter time to relapse and are a feature of advanced disease. In this review, the current understanding of the process of MM PC dissemination and the extrinsic and intrinsic factors potentially driving it are addressed through analysis of patient-derived MM PCs and MM cell lines as well as mouse models of homing and dissemination. In addition, we discuss how patient cytogenetic subgroups that present with highly disseminated disease, such as t(4;14), t(14;16) and t(14;20), suggest that intrinsic properties of MM PC influence their ability to disseminate. Finally, we discuss the possibility of using therapeutic targeting of tumour dissemination to slow disease progression and prevent overt relapse.

Acta Biochim Biophys Sin (Shanghai) 2019; 51:1258-1266. [PMID: 31769473 DOI: 10.1093/abbs/gmz130] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2019] [Revised: 09/30/2019] [Accepted: 09/30/2019] [Indexed: 12/13/2022] Open
Abstract
SRC3 plays critical roles in various biological processes of diseases, including proliferation, apoptosis, migration, and cell cycle arrest. However, the effect of SRC3 expression in mesenchymal stem cells (MSCs) on multiple myeloma (MM) is not clear yet. In our study, MSCs (MSC-SRC3, MSC-SRC3-/-) and MM cells were co-cultured in a direct or indirect way. The proliferation of MM cells was studied by CCK-8 and colony formation assays. The apoptosis and cell cycle of MM cells were detected by flow cytometry. In addition, the expressions of proteins in MM cells were detected by western blot analysis and the secretions of cytokines were measured by ELISA. Our data showed that the expression of SRC3 in bone marrow mesenchymal stem cells (BM-MSCs) could promote cell proliferation and colony formation of MM cells through accelerating the transformation of the G1/S phase, no matter what kind of culture method was adopted. Meanwhile, SRC3 expressed in BM-MSCs could inhibit the apoptosis of MM cells through the caspase apoptosis pathway and mitochondrial apoptosis pathway. Moreover, SRC3 could enhance the adhesion ability of MM cells through up-regulating the expression of adhesion molecules including CXCL4, ICAM1, VLA4, and syndecan-1. SRC3 also played a regulatory role in the progress of MM through the NF-κB and PI-3K/Akt pathways. SRC3 expressed in MSCs was found to promote the growth and survival of MM cells, while SRC3 silencing in MSCs could inhibit the development of MM. These results would be useful for developing a more effective new strategy for MM treatment.

Abstract
Background In calvarial mice, mesenchymal stem cells (MSCs) differentiate into osteoprogenitor cells and then differentiate into osteoblasts that differentiate into osteocytes, which become embedded within the bone matrix. In this case, the cells participating in bone formation include MSCs, osteoprogenitor cells, osteoblasts and osteocytes. The calvariae of C57BL/KaLwRijHsD mice consist of the following five bones: two frontal bones, two parietal bones and one interparietal bone. This study aimed to analyse some bone marker genes and bone related genes to determine whether these calvarial bones have different bone microenvironments. Methods C57BL/KaLwRijHsD calvariae were carefully excised from five male mice that were 4–6 weeks of age. Frontal, parietal, and interparietal bones were dissected to determine the bone microenvironment in calvariae. Haematoxylin and eosin staining was used to determine the morphology of different calvarial bones under microscopy. TaqMan was used to analyse the relative expression of Runx2, OC, OSX, RANK, RANKL, OPG, N-cadherin, E-cadherin, FGF2 and FGFR1 genes in different parts of the calvariae. Results Histological analysis demonstrated different bone marrow (BM) areas between the different parts of the calvariae. The data show that parietal bones have the smallest BM area compared to frontal and interparietal bones. TaqMan data show a significant increase in the expression level of Runx2, OC, OSX, RANKL, OPG, FGF2 and FGFR1 genes in the parietal bones compared with the frontal and interparietal bones of calvariae. Conclusion This study provides evidence that different calvarial bones, frontal, parietal and interparietal, contain different bone microenvironments.

Abstract
It is not clear why patients with an indolent form of multiple myeloma (MM) develop into an aggressive form with poor prognostic. We investigated the effect of a dietary calcium deficiency on tumor growth, osteolysis and gene expression in the 5T2MM murine model. Two groups of C57BL/KaLwRij mice received 5T2MM cells and started a diet with normal (0.8%; "normal-Ca-MM") or low calcium content (0.05%; "low-Ca-MM"). Two control groups (without 5T2MM cells) received either a normal or low calcium diet (normal-Ca and low-Ca groups). Tumor growth, osteolysis and marrow gene expression of the Wnt pathway, RANKL and MIP-1α were monitored at 6, 8 and 10 weeks (w) after cell injection. In low-Ca mice, serum level of PTH was higher after 10w; microCT showed trabecular bone loss and decrease of cortical thickness at the tibia. A higher M-protein level was evidenced at 10w and 4 mice developed paraplegia at 8/9w in low-Ca-MM group only. Numerous cortical perforations of the tibia were observed in MM groups with a marked decrease in cortical thickness in low-Ca-MM. At 6w, osteoclast number from the endosteum was significantly higher in low-Ca-MM compared to normal-Ca MM. This observation was not found at 8 and 10w. MicroCT of the lumbar vertebrae showed dramatic bone destruction in the low-Ca-MM group. qPCR revealed no difference in RANKL expression whereas differences were obtained in the expression of Lrp5/Lrp6 and MIP-1α from 6w. A low calcium diet induced higher bone destruction in the tibia and vertebra associated with an earlier decrease in bone formation level and a higher increase in bone resorption level at early time in the MM development.

Abstract
During the past decade preclinical studies have defined many of the mechanisms used by tumours to hijack the skeleton and promote bone metastasis. This has led to the development and widespread clinical use of bone-targeted drugs to prevent skeletal-related events. This understanding has also identified a critical dependency between colonizing tumour cells and the cells of bone. This is particularly important when tumour cells first arrive in bone, adapt to their new microenvironment and enter a long-lived dormant state. In this Review, we discuss the role of different bone cell types in supporting disseminated tumour cell dormancy and reactivation, and highlight the new opportunities this provides for targeting the bone microenvironment to control dormancy and bone metastasis.

Abstract
PURPOSE (111)In (typically as [(111)In]oxinate3) is a gold standard radiolabel for cell tracking in humans by scintigraphy. A long half-life positron-emitting radiolabel to serve the same purpose using positron emission tomography (PET) has long been sought. We aimed to develop an (89)Zr PET tracer for cell labelling and compare it with [(111)In]oxinate3 single photon emission computed tomography (SPECT). METHODS [(89)Zr]Oxinate4 was synthesised and its uptake and efflux were measured in vitro in three cell lines and in human leukocytes. The in vivo biodistribution of eGFP-5T33 murine myeloma cells labelled using [(89)Zr]oxinate4 or [(111)In]oxinate3 was monitored for up to 14 days. (89)Zr retention by living radiolabelled eGFP-positive cells in vivo was monitored by FACS sorting of liver, spleen and bone marrow cells followed by gamma counting. RESULTS Zr labelling was effective in all cell types with yields comparable with (111)In labelling. Retention of (89)Zr in cells in vitro after 24 h was significantly better (range 71 to >90%) than (111)In (43-52%). eGFP-5T33 cells in vivo showed the same early biodistribution whether labelled with (111)In or (89)Zr (initial pulmonary accumulation followed by migration to liver, spleen and bone marrow), but later translocation of radioactivity to kidneys was much greater for (111)In. In liver, spleen and bone marrow at least 92% of (89)Zr remained associated with eGFP-positive cells after 7 days in vivo. CONCLUSION [(89)Zr]Oxinate4 offers a potential solution to the emerging need for a long half-life PET tracer for cell tracking in vivo and deserves further evaluation of its effects on survival and behaviour of different cell types.

Abstract
Serglycin (SG) is mainly expressed by hematopoetic cells as an intracellular proteoglycan. Multiple myeloma cells constitutively secrete SG, which is also localized on the cell surface in some cell lines. In this study, SG isolated from myeloma cells was found to interact with collagen type I (Col I), which is a major bone matrix component. Notably, myeloma cells positive for cell-surface SG (csSG) adhered significantly to Col I, compared to cells lacking csSG. Removal of csSG by treatment of the cells with chondroitinase ABC or blocking of csSG by an SG-specific polyclonal antibody significantly reduced the adhesion of myeloma cells to Col I. Significant up-regulation of expression of the matrix metalloproteinases MMP-2 and MMP-9 at both the mRNA and protein levels was observed when culturing csSG-positive myeloma cells on Col I-coated dishes or in the presence of soluble Col I. MMP-9 and MMP-2 were also expressed in increased amounts by myeloma cells in the bone marrow of patients with multiple myeloma. Our data indicate that csSG of myeloma cells affects key functional properties, such as adhesion to Col I and the expression of MMPs, and imply that csSG may serve as a potential prognostic factor and/or target for pharmacological interventions in multiple myeloma.

Abstract
Multiple myeloma (MM) is a lethal human cancer characterized by a clonal expansion of malignant plasma cells in bone marrow. Mouse models of human MM are technically challenging and do not always recapitulate human disease. Therefore, new mouse models for MM are needed. Mineral-oil induced plasmacytomas (MOPC) develop in the peritoneal cavity of oil-injected BALB/c mice. However, MOPC typically grow extramedullary and are considered poor models of human MM. Here we describe an in vivo-selected MOPC315 variant, called MOPC315.BM, which can be maintained in vitro. When injected i.v. into BALB/c mice, MOPC315.BM cells exhibit tropism for bone marrow. As few as 10(4) MOPC315.BM cells injected i.v. induced paraplegia, a sign of spinal cord compression, in all mice within 3-4 weeks. MOPC315.BM cells were stably transfected with either firefly luciferase (MOPC315.BM.Luc) or DsRed (MOPC315.BM.DsRed) for studies using noninvasive imaging. MOPC315.BM.Luc cells were detected in the tibiofemoral region already 1 hour after i.v. injection. Bone foci developed progressively, and as of day 5, MM cells were detected in multiple sites in the axial skeleton. Additionally, the spleen (a hematopoietic organ in the mouse) was invariably affected. Luminescent signals correlated with serum myeloma protein concentration, allowing for easy tracking of tumor load with noninvasive imaging. Affected mice developed osteolytic lesions. The MOPC315.BM model employs a common strain of immunocompetent mice (BALB/c) and replicates many characteristics of human MM. The model should be suitable for studies of bone marrow tropism, development of osteolytic lesions, drug testing, and immunotherapy in MM.

Abstract
To evaluate potential new therapies and targets for treating multiple myeloma (MM), reproducible, biologically relevant in vivo models are required. Preclinical in vivo models of human MM allow investigators to evaluate novel therapies alone and in combination and quickly translate these results to the clinic where patients directly benefit, whether in the form of a new clinical trial, new doses and schedules, or new drug combinations. Presented in this unit are protocols for generating and maintaining a human extramedullary MM tumor in mice. Additionally, the extramedullary tumor can be excised and digested into a single-cell suspension and the human MM cells injected into mice subcutaneously, intravenously, or intratibially. Once these tumors are generated, they can be used to evaluate novel anti-MM agents and other therapies.

Abstract
The spread of multiple myeloma (MM) involves (re)circulation into the peripheral blood and (re)entrance or homing of MM cells into new sites of the BM. Hypoxia in solid tumors was shown to promote metastasis through activation of proteins involved in the epithelial-mesenchymal transition (EMT) process. We hypothesized that MM-associated hypoxic conditions activate EMT-related proteins and promote metastasis of MM cells. In the present study, we have shown that hypoxia activates EMT-related machinery in MM cells, decreases the expression of E-cadherin, and, consequently, decreases the adhesion of MM cells to the BM and enhances egress of MM cells to the circulation. In parallel, hypoxia increased the expression of CXCR4, consequently increasing the migration and homing of circulating MM cells to new BM niches. Further studies to manipulate hypoxia to regulate tumor dissemination as a therapeutic strategy are warranted.

Abstract
We provide an overview on soft-tissue extramedullary plasmacytomas (EMPs) in multiple myeloma (MM). We reviewed the incidence of EMPs in MM, myeloma bone marrow homing, possible mechanisms of extramedullary spread, and prognosis and response to therapy. The incidence of EMPs is 7% to 18% at MM diagnosis and up to 20% at relapse. The current notion that EMPs are more frequent after treatment with novel agents remains to be proven, especially considering that different patterns of disease recurrence can emerge as patients live longer in the era of novel drugs. Bone marrow genetic abnormalities are not associated with extramedullary spread per se, which also suggests that microenvironmental interactions are key. Possible mechanisms of extramedullary spread include decreased adhesion molecule expression and downregulation of chemokine receptors. EMPs usually show plasmablastic morphology with negative CD56 expression. High-dose therapy with autologous stem-cell transplantation (ASCT) can overcome the negative prognostic impact of extramedullary disease in younger selected patients. EMPs do not typically respond to thalidomide alone, but in contrast, responses to bortezomib have been reported. The incidence of EMPs in patients with MM is high and is associated with poor outcome in patients treated conventionally. A potential first-line treatment option seems to be a bortezomib-containing regimen followed by ASCT, whenever possible. Experimental studies on the mechanisms of myeloma cell adhesion, myeloma growth at extramedullary sites, and drug sensitivity are priorities for this area of continuing therapeutic challenge.

Abstract
OBJECTIVE Microenvironmental interactions of malignant B cells can modulate various in vitro physiological responses, including proliferation, migration, apoptosis, and drug resistance. Disease manifestations of human malignant B-cell variants, isolated based on their differential interactions with fibronectin, were examined in nonobese diabetic/severe combined immunodeficient (NOD/SCID) mice. MATERIALS AND METHODS Disease manifestations were assessed by pathological examinations and skeletal imaging of NOD/SCID mice injected with malignant B-cell variants. Dissemination patterns were analyzed by whole-body real-time imaging of mice injected with fluorescence-labeled malignant cells. RESULTS Initial dissemination patterns and dynamics of both high (type A) and low (type F)-adherent variants, following intravenous inoculation, were similar. Both cell types reached the spleen and liver within 30 minutes after injection, then increasingly accumulated within the bone marrow. Mice injected with type-A cells developed multiple myeloma-like disease within the bone marrow, with multiple lytic bone lesions. In contrast, type-F cells displayed low tumorigenic capacity in spite of their efficient homing to the bone marrow niche. In addition, type-A cells grew as extramedullary tumors in some of the intravenous-inoculated mice, and formed solid tumors following subcutaneous injection. Both cell variants retained their characteristics surface markers following in vivo outgrowth as tumors, indicating that at least some of their properties are relatively stable. CONCLUSION Data suggest that the differential tumorigenicity of B-cell adhesive variants is attributable to the capacity of type-A cells to survive and proliferate within the bone marrow, rather than to different initial dissemination of the two cell populations.

Abstract
Multiple myeloma (MM) remains incurable despite high-dose chemotherapy with stem cell support. There is need, therefore, for continuous efforts directed toward the development of novel rational-based therapeutics for MM, which requires a detailed knowledge of the mutations driving this malignancy. In improving the success rate of effective drug development, it is equally imperative that biologic systems be developed to better validate these target genes. Here we review the recent developments in the generation of mouse models of MM and their impact as preclinical models for designing and assessing target-based therapeutic approaches.

Abstract
Multiple myeloma (MM) is a malignant B-cell disorder characterized by a monoclonal expansion of plasma cells (PC) in the bone marrow (BM). During the main course of disease evolution, MM cells depend on the BM microenvironment for their growth and survival. Reciprocal interactions between MM cells and the BM mediate not only MM cell growth, but also protect them against apoptosis and cause bone disease and angiogenesis. A striking feature of MM represents the predominant localization and retention of MM cells in the BM. Although BM PC indeed represent the main neoplastic cell type, small numbers of MM cells can also be detected in the peripheral blood circulation. It can be assumed that these circulating cells represent the tumour-spreading component of the disease. This implicates that MM cells have the capacity to (re)circulate, to extravasate and to migrate to the BM (homing). In analogy to the migration and homing of normal leucocytes, the BM homing of MM cells is mediated by a multistep process of extravasation with adhesion to the endothelium, invasion of the subendothelial basement membrane, followed by further migration within the stroma, mediated by chemotactic factors. At the end stage of disease, MM cells are thought to develop autocrine growth supporting loops that enable them to survive and proliferate in the absence of the BM microenvironment and to become stroma-independent. In this stage, the number of circulating cells increases and growth at extramedullary sites can occur, associated with alteration in adhesion molecule and chemokine receptor expression. This review summarizes the recent progress in the study of the extravasation and homing mechanisms of MM cells.

Abstract
Erythropoietin (Epo) is the main erythropoietic hormone. Recombinant human Epo (rHuEpo) is thus used in clinical practice for the treatment of anemia. Accumulating data reveals that Epo exerts pleiotropic activities. We have previously shown an anti-neoplastic activity of Epo in murine multiple myeloma (MM) models, and in MM patients. Our findings that this anti-neoplastic effect operates via CD8+ T lymphocytes led us to hypothesize that Epo possesses a wider range of immunomodulatory functions. Here we demonstrate the effect of Epo on B lymphocyte responses, focusing on three experimental models: (i) tumor-bearing mice, (5T2 MM mouse); (ii) antigen-injected healthy mice; and (iii) antigen-injected transgenic mice (tg6), overexpressing human Epo. In the MM model, despite bone marrow dysfunction, Epo-treated mice retained higher levels of endogenous polyclonal immunoglobulins, compared to their untreated controls. In both Epo-treated wild type and tg6 mice, Epo effect was manifested in the higher levels of splenocyte proliferative response induced in vitro by lipopolysaccharide. Furthermore, these mice had increased in vivo production of anti-dinitrophenyl (DNP) antibodies following immunization with DNP-keyhole limpet hemocyanin. Epo-treated mice showed an enhanced immune response also to the clinically relevant hepatitis B surface antigen. These findings suggest a potential novel use of rHuEpo as an immunomodulator.

Abstract
Multiple myeloma (MM) is a plasma cell malignancy, characterized by the localization of the MM cells in the bone marrow (BM), where they proliferate and induce osteolysis. The MM cells first need to home or migrate to the BM to receive necessary survival signals. In this work, we studied the role of CCR1 and CCR5, two known chemokine receptors, in both chemotaxis and osteolysis in the experimental 5TMM mouse model. A CCR1-specific (BX471) and a CCR5-specific (TAK779) antagonist were used to identify the function of both receptors. We could detect by RT-PCR and flow cytometric analyses the expression of both CCR1 and CCR5 on the cells and their major ligand, macrophage inflammatory protein 1alpha (MIP1alpha) could be detected by ELISA. In vitro migration assays showed that MIP1alpha induced a 2-fold increase in migration of 5TMM cells, which could only be blocked by TAK779. In vivo homing kinetics showed a 30% inhibition in BM homing when 5TMM cells were pre-treated with TAK779. We found, in vitro, that both inhibitors were able to reduce osteoclastogenesis and osteoclastic resorption. In vivo end-term treatment of 5T2MM mice with BX471 resulted in a reduction of the osteolytic lesions by 40%; while TAK779 treatment led to a 20% decrease in lesions. Furthermore, assessment of the microvessel density demonstrated a role for both receptors in MM induced angiogenesis. These data demonstrate the differential role of CCR1 and CCR5 in MM chemotaxis and MM associated osteolysis and angiogenesis.

Abstract
Renal failure is one of the main complications in multiple myeloma (MM) and histopathological lesions are due to light chains accumulation in the kidney. The 5T2MM mouse model closely mimics osteolytic lesions observed in clinics. We studied the occurrence of pathological changes in the kidney of mice inoculated with 5T2MM myeloma cells. No renal lesions due to light chain deposition were observed after histological, immunological staining and dosage of creatinine in serum and urine. PTH levels decreased in 5T2MM mice, confirming the absence of secondary hyperparathyroidism. Osteolytic lesions appear to be the unique consequence of 5T2MM cells inoculation.

Abstract
Angiogenesis is a constant hallmark of multiple myeloma (MM) progression and has prognostic potential. It is induced by plasma cells via angiogenic factors with the transition from monoclonal gammopathy of undetermined significance (MGUS) to MM, and probably with loss of angiostatic activity on the part of MGUS. The pathophysiology of MM-induced angiogenesis is complex and involves both direct production of angiogenic cytokines by plasma cells and their induction within the microenvironment. The latter are secreted by stromal cells, endothelial cells (EC) and osteoclasts, and promote plasma cell growth, survival and migration, as well as paracrine cytokine secretion and angiogenesis in the bone marrow milieu. Angiogenesis is also supported by inflammatory cells following their recruitment and activation by plasma cells. Finally, circulating EC and endothelial precursor cells (EPC) contribute to the neovascularization, and the presence of EPC suggests that vasculogenesis (new vessel formation from EPC) may also contribute to the full MM vascular tree.

Abstract
AbstractInsulin-like growth factor 1 (IGF-1) plays a pleiotropic role in multiple myeloma (MM), that is, in survival, proliferation, chemotaxis, and angiogenesis. Strategies targeting the IGF-1 receptor (IGF-1R) may therefore be important to develop efficient anti-MM agents. In this work we investigated the effect of an IGF-1R tyrosine kinase (IGF-1RTK) inhibitor (picropodophyllin or PPP) in the 5T33MM mouse model. In vitro data showed that PPP reduced IGF-1R autophosphorylation and downstream ERK activation, leading to inhibition of IGF-1–stimulated proliferation and vascular endothelial growth factor (VEGF) secretion of MM cells. In an in vivo study, PPP reduced the bone marrow tumor burden and serum paraprotein in 5T33MM mice by 77% and 90%, respectively, compared to vehicle-treated animals. Angiogenesis was assessed by quantifying the microvessel density on CD31-stained paraffin sections and this was reduced by 60% in the PPP-treated group. In a separate survival experiment, Kaplan-Meier analysis demonstrated a significant increase in survival in PPP-treated 5T33MM animals compared to the vehicle controls (28 versus 18 days). These data suggest that the IGF-1RTK inhibitor PPP possesses a marked antitumor activity and strongly points to the possibility of using IGF-1R inhibitors in the treatment of MM.

Abstract
Myeloma is a deadly B-cell neoplasm, characterized by the monoclonal proliferation of plasma cells, the development of osteolytic lesions, and the induction of angiogenesis. Myeloma cells are predominantly localized in the marrow where they receive the appropriate survival and proliferation signals. To reach or spread over the marrow, the myeloma cells need to migrate from the vascular to the extravascular compartment of the marrow. A process called "homing". In this review, the steps of the homing scheme, analyzed in the 5TMM model, will be described. These murine models originated from spontaneously developed myeloma in elderly mice and have since been propagated by intravenous injection of myeloma cells into young syngeneic mice. These models resemble the human condition closely. The different studies reported here demonstrate that adhesion of 5TMM cells to marrow endothelial cells is partially mediated by CD44v10 and to stromal cells by CD44v6. The 5TMM cells migrate to the marrow through the effects of MCP-1, laminin-1, and IGF-1. Once past the marrow endothelium, they invade the extravascular compartment of the marrow by secreting MMP-9 and uPA. When they have settled in the marrow, they become susceptible to the effects of IGF-1, which stimulates the cells to proliferate and produce VEGF. Furthermore, studies targeting the marrow with inhibitors will be highlighted. These studies show that the 5TMM models are useful for unraveling basic biological processes and for identifying new therapeutic targets.

Abstract
Matrix metalloproteinases (MMPs) are known to play a role in cell growth, invasion, angiogenesis, metastasis, and bone degradation, all important events in the pathogenesis of cancer. Multiple myeloma is a B-cell cancer characterized by the proliferation of malignant plasma cells in the bone marrow, increased angiogenesis, and the development of osteolytic bone disease. The role of MMPs in the development of multiple myeloma is poorly understood. Using SC-964, a potent inhibitor of several MMPs (MMP-2, -3, -8, -9, and -13), we investigated the role of MMPs in the 5T2MM murine model. Reverse transcriptase-polymerase chain reaction demonstrated the presence of mRNA for MMP-2, -8, -9, and -13 in 5T2MM-diseased bone marrow. Mice bearing 5T2MM cells were given access to food containing SC-964. The concentration of SC-964 measured in the plasma of mice after 11 days of treatment was able to inhibit MMP-9 activity in gelatin zymography. Treatment of 5T2MM-bearing mice resulted in a significant reduction in tumor burden, a significant decrease in angiogenesis, and partially protective effect against the development of osteolytic bone disease. The direct role of MMPs in these different processes was confirmed by in vitro experiments. All these results support the multifunctional role of MMPs in the development of multiple myeloma.

Abstract
In multiple myeloma (MM), bone marrow microenvironment has an important role for the survival and growth of plasma cells. We previously showed that a high bone turnover, induced by ovariectomy, increased MM cells growth in the 5T2MM model. The present study characterized a new plasma cell line (5THL) which was isolated from 5T2MM mice previously ovariectomized. Cells were propagated unchanged in normal C57BL/KaLwRij mice during six generations. 5THL was compared to the original 5T2MM phenotype. Paraproteinemia was detected 6 weeks post injection in 5THL mice and after 8 weeks in 5T2MM mice. All 5THL mice developed a hind-limb paralysis after 10 weeks. 5T2MM mice were euthanized at 16 weeks, due to a more progressive development of the disease. In 5THL mice, osteolytic lesions were observed after 8 weeks and severe bone destruction was evidenced at 10 weeks. In 5T2MM mice, minimal lesions were observed only after 10 weeks. Like in 5T2MM mice, no extra osseous lesions were observed in 5THL mice. The 5THL MM model closely mimics human myeloma with higher and faster bone aggressiveness. This new aggressive cell line, with a preserved phenotype, was selected by an altered microenvironment due to an increased bone turnover.

Abstract
Insulin-like growth factor-1 (IGF-1) has been described as an important factor in proliferation, cell survival and migration of multiple myeloma (MM) cells. Angiogenesis correlates with development and prognosis of the MM disease. Vascular endothelial growth factor (VEGF) is one of the prominent factors involved in this process. The different functions of IGF-1 were investigated in the 5TMM mouse model with emphasis on proliferation, migration and VEGF secretion, and the signalling pathways involved. Western Blot analysis revealed that ERK1/2 and Akt (PKB) were activated after IGF-1 stimulation. The activation of ERK1/2 was reduced by the PI3K inhibitor Wortmannin, implying that the PI3K pathway is involved in its activation. Insulin-like growth factor-1 induced an increase in DNA synthesis in MM cells, which was mediated by a PI3K/Akt-MEK/ERK pathway. Insulin-like growth factor-1 enhanced F-actin assembly and this process was only PI3K mediated. Stimulation by IGF-1 of VEGF production was reduced by PD98059, indicating that only the MEK–ERK pathway is involved in IGF-1-stimulated VEGF production. In conclusion, IGF-1 mediates its multiple effects on MM cells through different signal transduction pathways. In the future, we can study the potential in vivo effects of IGF-1 inhibition on tumour growth and angiogenesis in MM.

Abstract
The migration of multiple myeloma (MM) cells from the circulation into the bone marrow (BM) implicates that they must have the capacity to cross the BM endothelium including the subendothelial basement membrane. In this study, human CD138+ MM cells were immunomagnetically isolated from BM samples of MM patients and their invasion through Matrigel, that is, a reconstituted basement membrane, was determined. We demonstrated that primary MM cells have the capacity to transmigrate through basement membrane and that this invasiveness was considerably increased when assessed on Matrigel filters coated with BM endothelial cells (EC) (4LHBMEC line) (transendothelial invasion). The isolated MM cells were shown by zymography to secrete matrix metalloproteinase (MMP)-9 and anti-MMP-9 antibodies inhibited transendothelial invasion, indicating that MMP-9 is involved in this process. BM EC were found to increase the MMP-9 secretion in MM cells, indicating that EC enhance MM cell invasion through stimulation of MMP-9 secretion. BM EC were found to produce hepatocyte growth factor (HGF), and this cytokine also stimulated MMP-9 secretion in MM cells, while anti-HGF antibodies significantly inhibited EC-stimulated MM cell invasion. In summary, our findings provide evidence that MM cell-BM EC interactions enhance the invasion of human MM cells through stimulation of MMP-9 secretion.

Abstract
Bone destruction is the main clinical consequence of multiple myeloma (MM). It is known that a "vicious circle" exists between bone and myeloma cells with plasma cells stimulating bone cells, which in return stimulate the neoplastic growth. We hypothesized that an accelerated bone remodeling induced by ovariectomy (OVX) could provide a more fertile environment for the myeloma cell growth. Ovariectomy performed on C57BL/KaLwRij mice resulted in reduced trabecular bone volume and increased osteoclast number. To test our hypothesis, we ovariectomized C57BL/KaLwRij mice one week before injection of 5T2MM myeloma cells. A non-OVX 5T2MM group was used as control. Ovariectomy increased the tumor growth and induced an earlier development of osteolytic lesions. OVX 5T2MM mice were euthanized at 10 weeks, instead of 16 weeks, for the non-OVX 5T2MM, mice because of the accelerated development of disease in OVX animals. Treatment of OVX 5T2MM mice with pamidronate reduced osteolysis but had little effect on the time development of the tumor. This combined model (ovariectomy + 5T2MM) confirmed the interdependence of bone and myeloma cells and could explain the some sudden burden of indolent MM into aggressive MM in humans.

Abstract
Multiple myeloma (MM) is a B cell neoplasm characterized by the monoclonal proliferation of plasma cells in the bone marrow, the development of osteolytic lesions and the induction of angiogenesis. These different processes require three-dimensional interactions, with both humoral and cellular contacts. The 5TMM models are suitable models to study these interactions. These murine models originate from spontaneously developed myeloma in elderly mice, which are propagated by in vivo transfer of the myeloma cells into young syngeneic mice. In this review we report on studies performed in the 5TMM models with special emphasis on the homing of the myeloma cells, the characterization of the migrating and proliferating clone and the identification of the isotype switch variants. The bone marrow microenvironment was further targeted with osteoprotegerin (OPG) to block the RANK/RANKL/OPG system and with potent bisphosphonates. Both treatments resulted in a significant protection against myeloma-associated bone disease, and they decreased myeloma disease, as evidenced by a lower tumor load and an increased survival of the mice. These different studies demonstrate the strength of these models, not only in unraveling basic biological processes but also in the testing of potentially new therapeutic targets.

Abstract
At clinical presentation, multiple myeloma (MM) is already a well-established disease. The processes involved in earlier stages are, however, unknown. Here the 5T2MM murine model was used to analyze differentiation, proliferation, invasion, and apoptosis of MM cells during disease progression. Naive mice were injected with 5T2MM cells and from the onset of the experiment 3 mice were killed each week until the end stage. Myeloma cells were isolated from the bone marrow and selected by sequential gating of 5T2MM idiotype(+) cells by flow cytometry. Microscopic analysis of these sorted 5T2MM idiotype(+) cells confirmed their identity as true myeloma cells. Based on serum paraprotein concentration and bone marrow tumor load, 3 disease stages were distinguished: a quiescent stage, an intermediate stage, and an end stage, of slow, moderate, and accelerated tumor progression, respectively. In the quiescent stage, the majority of the myeloma cells were CD45(+)CD138(-)IL-6R alpha(+), corresponding to an immature, invasive, and apoptosis-resistant phenotype. In the end stage the majority of the myeloma cells had differentiated into CD45(-)CD138(+)IL-6R alpha(-) cells, corresponding to a mature, less invasive, and apoptosis-sensitive phenotype. In the intermediate stage a gradual transition from the quiescent toward the end stage was observed. In line with these data, analysis of sorted 5T2MM cells demonstrated a significant decrease in invasive capacity and a significant increase in (dexamethasone-induced) apoptosis sensitivity and in proliferation during the disease progression. These data suggest that myeloma disease progression is a multistage and dynamic process of differentiation, proliferation, invasion, and apoptosis.

Abstract
The restricted bone marrow (BM) localisation of multiple myeloma (MM) cells most likely results from a specific homing influenced by chemotactic factors, combined with the proper signals for growth and survival provided by the BM microenvironment. In analogy to the migration and homing of normal lymphocytes, one can hypothesise that the BM homing of MM cells is mediated by a multistep process, involving the concerted action of adhesion molecules and chemokines. In this study, we report that primary MM cells and myeloma derived cell lines (Karpas, LP-1 and MM5.1) express the chemokine receptor CCR2. In addition, we found that the monocyte chemotactic proteins (MCPs) MCP-1, -2 and -3, three chemokines acting as prominent ligands for CCR2, are produced by stromal cells, cultured from normal and MM BM samples. Conditioned medium (CM) from BM stromal cells, as well as MCP-1, -2 and -3, act as chemoattractants for human MM cells. Moreover, a blocking antibody against CCR2, as well as a combination of neutralizing antibodies against MCP-1, -2 and -3, significantly reduced the migration of human MM cells to BM stromal cell CM. The results obtained in this study indicate the involvement of CCR2 and the MCPs in the BM homing of human MM cells.

Abstract
Multiple myeloma (MM) is an incurable plasma cell cancer, localized in the bone marrow (BM). The mechanisms used by these cells to (re-)enter this organ remain largely unknown. Recently, we reported that both CD45+ and CD45- myeloma cells home to the BM and induce myeloma disease. In this work, we investigated the underlying mechanisms involved in the homing of CD45+ and CD45- myeloma cells in the experimental 5T2MM and 5T33MM murine models. In vivo tracing of flow cytometric sorted and radioactively labeled CD45 subsets revealed a reduced homing of the CD45- 5TMM cells to the BM as compared to the CD45+ 5TMM cells. Migration assays demonstrated an impaired chemotaxis towards BM endothelial cell conditioned medium, BM stromal cell conditioned medium and towards the basement membrane component laminin-1 of the CD45- 5TMM cells compared to the CD45+ subset. Matrix metalloproteinase-9 (MMP-9) and urokinase type plasminogen activator (uPA) are key extracellular matrix proteases involved in the invasion of cancer cells. Inhibitor and antibody blocking experiments demonstrated the involvement of both in the invasion of the 5TMM cells. CD45- 5TMM cells had a low secretion of MMP-9 and (for the non-aggressive line 5T2MM only) a low cell surface expression of uPA receptor, as revealed by gelatin zymography and flow cytometric analysis, respectively. Accordingly, the synthetic basement membrane invasive capacity of the CD45- 5TMM subpopulations was also impaired. Our results indicate that CD45+ and CD45- 5T myeloma cells have a differential BM homing attributable to differential migratory and invasive capacities.

Abstract
One of the main characteristics of multiple myeloma (MM) cells is their specific homing and growth in the bone marrow (BM). For their homing, MM cells need chemotactic signals to be attracted towards the BM and to be activated. Profound knowledge of the different chemokines for MM cells and their signal transduction pathways is necessary to interfere in this process. We studied here an extra possible tool for the investigation of the different chemokines and their pathways. The 5T experimental mouse model was used to investigate the migration of MM cells towards BM stromal cells. We studied the changes of the F-actin content in the 5TMM cells in the presence of BM stromal cell conditioned medium and we correlated this with their migratory capacity. F-actin became polarized when the cells were migrating, in contrast to nonmigrating cells. This polarization could not only be seen by fluorescence and confocal laser scanning microscopy, but also could be quantified by fluorometry and flow cytometry. The correlation between the F-actin content of the MM cells and their migration capacity thus makes its quantification a useful tool in studying their migratory behavior.

Abstract
MM is a B-cell malignancy mainly characterized by monoclonal expansion of plasma cells in the BM, presence of paraprotein in serum and occurrence of osteolytic bone lesions. MMPs are a family of proteolytic enzymes that can contribute to cancer growth, invasion, angiogenesis, bone degradation and other processes important in the pathogenesis of MM. We investigated MMP-9 production in the 5T33MM murine model. Expression of MMP-9 protein in supernatant and cell extracts was analyzed by gelatin zymography. The in vitro, stroma-independent variant 5T33MMvt showed no protein expression of MMP-9 in contrast to in vivo growing MM cells, 5T33MMvv. However, when 5T33MMvt cells were injected into naive mice and isolated after tumor take (5T33MMvt-vv), they secreted a significant amount of MMP-9. These results were confirmed by specific staining of cytospins with an anti-MMP-9 antibody. The MMP-9 production by 5T33MMvt-vv cells disappeared when the cells were recultured in vitro. These data demonstrated that upregulation of MMP-9 occurs in vivo and that this process is dependent on the microenvironment. Cocultures of 5T33MMvt cells with STR10 BMECs induced MMP-9 in MM cells, as determined by both gelatin zymography and flow-cytometric analysis. In conclusion, our results demonstrate that MMP-9 production by MM cells is upregulated in vivo by the interaction of MM cells with BMECs.

Abstract
Homing of multiple myeloma (MM) cells to the bone marrow (BM) requires transendothelial migration. In the present work we tested whether monocyte chemoattractant protein-1 (MCP-1) and CCR2, the high affinity receptor for MCP-1, are involved in this process. Murine 5T2 and 5T33MM cell lines were selected as source of MM cells and STR4, 10 and 12 of BM endothelial cells (BMEC). RT-PCR demonstrated transcripts for MCP-1 in BMEC and ELISA the presence of MCP-1 protein in culture medium. RNase protection assay showed mRNA expression for CCR2, and FACS analysis the presence of CCR2 protein on the MM cells. EC conditioned medium induced chemoattraction of MM cells, a phenomenon inhibited by anti-MCP-1 antibodies. In conclusion, MM cells express CCR2 and are attracted by MCP-1 secreted by BMEC. We suggest that local MCP-1 production by BMEC is one of the mechanisms involved in homing of myeloma cells to the BM.

Abstract
BACKGROUND Liver sinusoidal endothelial cells (LSECs) react to different anti-actin agents by increasing their number of fenestrae. A new structure related to fenestrae formation could be observed when LSECs were treated with misakinolide. In this study, we investigated the effects of two new actin-binding agents on fenestrae dynamics. High-resolution microscopy, including immunocytochemistry and a combination of fluorescence- and scanning electron microscopy was applied. RESULTS Halichondramide and dihydrohalichondramide disrupt microfilaments within 10 minutes and double the number of fenestrae in 30 minutes. Dihydrohalichondramide induces fenestrae-forming centers, whereas halichondramide only revealed fenestrae-forming centers without attached rows of fenestrae with increasing diameter. Correlative microscopy showed the absence of actin filaments (F-actin) in sieve plates and fenestrae-forming centers. Comparable experiments on umbilical vein endothelial cells and bone marrow sinusoidal endothelial cells revealed cell contraction without the appearance of fenestrae or fenestrae-forming centers. CONCLUSION (I) A comparison of all anti-actin agents tested so far, revealed that the only activity that misakinolide and dihydrohalichondramide have in common is their barbed end capping activity; (II) this activity seems to slow down the process of fenestrae formation to such extent that it becomes possible to resolve fenestrae-forming centers; (III) fenestrae formation resulting from microfilament disruption is probably unique to LSECs.

Abstract
The 67 kD laminin receptor (67LR) binds laminin-1 (LN), major component of the basement membrane, with high affinity. In this study, we demonstrated that human multiple myeloma cell lines (HMCL) and murine 5T2MM cells express 67LR. CD38(bright+) plasma cells in fresh multiple myeloma (MM) bone marrow (BM) samples showed weaker 67LR expression, but expression increased after direct exposure to a BM endothelial cell line (4LHBMEC). LN stimulated the in vitro migration of 3 HMCL (MM5.1, U266 and MMS.1), primary MM cells and the murine 5T2MM cells. 67LR has been shown to mediate the actions of LN through binding to CDPGYIGSR, a 9 amino acid sequence from the B1 chain of LN. MM cell migration was partially blocked by peptide 11, a synthetic nonapeptide derived from this amino sequence and also by a blocking antiserum against 67LR. Co-injection of peptide 11 with 5T2MM cells in a murine in vivo model of MM resulted in a decreased homing of 5T2MM cells to the BM compartment. In conclusion, LN acts as a chemoattractant for MM cells by interaction with 67LR. This interaction might be important during extravasation of circulating MM cells.

Abstract
Isotype-switch variants can easily be detected in a significant proportion of multiple myeloma (MM) patients. The biological significance of these isotype-switch variants remains obscure. Therefore, we studied the appearance of these isotype-switch variants in two murine MM models, 5T2MM and 5T33MM, both of IgG isotype. With a MM-specific PCR assay we could detect isotype-switch variants in the bone marrow of both the 5T2MM and the 5T33MM bearing mice, reflecting again the close resemblance of this mouse model to the human MM. These isotype-switch variants were not found in an in vitro stroma-independent variant of the 5T33MM line. However, when this 5T33MMvitro line was injected into young syngeneic mice, isotype-switch variants appeared thereafter in the isolated tumour cells. These isotype-switch variants could only originate from the MM-IgG expressing cell since IgG subclones from the 5T33MMvitro line again gave rise to isotype-switch variants. The appearance of IgA cells can be explained by down-stream switching of IgG to IgA, while the emergence of IgM cells have to occur via trans-switching to the sister chromatid as the Cmu region is deleted from the CIS-chromosome. This study demonstrates that isotype-switch variants originate from the major tumour clone suggesting no role for the MM-IgM expressing cell as a pre-switch precursor MM cell. The appearance of isotype-switch variants should be considered as a rare but normal event now becoming visible due to the high number of clonal cells present in MM.

Abstract
The presence of myeloma cells in the blood circulation. implicates that these cells must have the potential to extravasate and home to the bone marrow environment. Using the 5T2 MM mouse model, we could demonstrate that the restricted localization of myeloma cells in the bone marrow is the result of selective migration of myeloma cells in the bone marrow combined with a selective growth of the tumour cells in the bone marrow microenvironment. Moreover, we showed that 5T2 MM cells bind in vitro selectively to bone marrow-derived endothelial cells (EC) and not to lung-derived EC. In order to identify which chemotactic molecules mediate the transendothelial migration of myeloma cells, we examined the motility-inducing effect of different extracellular matrix proteins on myeloma cell lines. We found that laminin-1 a major component of the basement membrane, triggers the motility of both human myeloma cells and 5T2 MM cells, through the 67 kD laminin receptor. Because of the broad distribution of laminin in extracellular matrices throughout the body, it is clear that this molecule on itself can not be the only factor that determines the specificity of myeloma cell homing. In the 5T2 MM model we identified IGF-1 as a more specific bone marrow derived chemoattractant for myeloma cells. In addition we demonstrated that the marrow microenvironment can upregulate the expression of the IGF-1 receptor on 5T mouse myeloma cells. In the end phase of the disease, increasing numbers of myeloma cells are detectable in the peripheral blood and extramedullary tumour growth can occur. We found that the stroma-independent variant of the human MM5 myeloma cell line showed an increased in vitro motility as compared to the stroma-dependent variant. By representational difference analysis we demonstrated that the stroma-dependent MM5 cells show a downregulation of the motility-related protein (MRP-I CD9) which might reflect the involvement of this molecule in the regulation of myeloma cell extravasation.

Abstract
Multiple myeloma, a plasma cell malignancy, is predominantly localized in the bone marrow. These tumoral cells display a heterogeneous expression of CD45. It is, however, unclear which subpopulation is responsible for the homing and outgrowth of the myeloma cells. In this work, we investigated the in vivo homing, proliferation, and differentiation of both CD45+ and CD45- cells in two murine myeloma models.5T2MM and 5T33MM in vivo lines of murine multiple myeloma were used. CD45 and IGF-I receptor expression was analyzed by FACS. Proliferative capacity was assessed by in vivo bromodeoxyuridine incorporation. 5TMM cells were separated into CD45+ and CD45- fractions by MACS. Initial homing was investigated in vivo by tracing of radioactively labeled cells. Myeloma cells were detected by FACS and histology. Osteolytic lesions were analyzed by radiography. Both CD45+ and CD45- 5TMM cells were able to home to the bone marrow, although the migration of the latter subset was lower, which was related to a low IGF-I receptor expression. Recipients of both fractions developed myeloma as evidenced by the presence of serum paraprotein, osteolytic lesions, and bone marrow infiltration by myeloma cells. The tumor load in the recipients of CD45- cells was higher than the CD45+ cells, which could be explained by a lower proliferation rate of the latter population. While the separated cells before injection had a homogenous expression of CD45, cells isolated from the bone marrow of these terminally diseased mice had a heterogeneous expression pattern, indicating an in vivo differentiation pattern of CD45- to CD45+ cells and vice versa. We conclude that both CD45+ and CD45- 5TMM subpopulations contain clonogenic myeloma cells with bone marrow homing and proliferative capacity.
