Abstract
Melanoma is an immunogenic tumor that can metastasize quickly to proximal and distal sites, thus complicating the application of therapeutic modalities. Numerous mouse model systems have been used to gain understanding of the immunobiology and metastatic potential of melanoma. Here, we report the optimization of a syngeneic mouse melanoma model protocol using the mouse B16-derived melanoma cell line B16F10 that ensures the production of tumors on mice pinnae that are similar in size between animals and that enlarge in a time-dependent manner. In this model, B16F10 cells are first allowed to develop tumors after injection in the interscapular area or flank of C57BL/6J mice. Subsequently, the tumors are harvested, cells dissociated and injected into mouse pinnae. Dose-dependent studies revealed that injection of 2 × 105 cells allowed for slow tumor enlargement, producing tumors averaging 100 mm³ within 2 to 3 wk with a metastatic frequency of 100%. This experimental protocol will be useful in dissecting the immunobiology of melanoma tumor development and metastasis and the evaluation of immunotherapeutic antimelanoma therapies.

Abstract
BACKGROUND Metastasis is the main cause of mortality in cancer patients. Two major routes of cancer cell spread are currently being recognized: dissemination via blood vessels (hematogenous spread) and dissemination via the lymphatic system (lymphogenous spread). Here, our current knowledge on the role of both blood and lymphatic vessels in cancer cell metastasis is summarized. In addition, I will discuss why cancer cells select one or both of the two routes to disseminate and I will provide a short description of the passive and active models of intravasation. Finally, lymphatic vessel density (LVD), blood vessel density (BVD), interstitial fluid pressure (IFP) and tumor hypoxia, as well as regional lymph node metastasis and the recently discovered primo vascular system (PVS) will be highlighted as important factors influencing tumor cell motility and spread and, ultimately, clinical outcome. CONCLUSIONS Lymphangiogenesis and angiogenesis are important phenomena involved in the spread of cancer cells and they are associated with a poor prognosis. It is anticipated that new discoveries and advancing knowledge on these phenomena will allow an improvement in the treatment of cancer patients.

Abstract
Interferon (IFN)-α and IFN-β are type I IFNs which are known to exert an antitumor effect on malignant melanoma. The aim of this study was to evaluate and compare the efficacy of IFN-α2b and IFN-β1a on primary tumor growth and lymph node metastasis, and to examine the mechanisms of lymph node metastasis. The efficacy of IFN-α2b and IFN-β1a was evaluated using a human melanoma xenograft model. We further examined the effect of IFNs on lymphangiogenic growth factors in human melanoma cells. IFN-β1a showed a stronger antiproliferative and proapoptotic effect, whereas IFN-α2b inhibited tumor growth and lymph node metastasis through inhibition of lymphangiogenesis. Both IFN-α2b and IFN-β1a were effective in inhibiting lymph node metastasis compared with the control. Microvessel density decreased in tumors treated with IFN-α2b and IFN-β1a compared with the control, without statistical significance. Lymphatic vessel density decreased significantly only in tumors treated with IFN-α2b (P<0.05). Both IFN-α2b and IFN-β1a decreased in-vitro and in-vivo vascular endothelial growth factor (VEGF)-C and VEGF receptor-3 protein expression and secretory VEGF-C level in vitro. IFN-α2b showed an earlier and sustained effect in decreasing VEGF-C and VEGF receptor-3 protein expression and a superior effect in decreasing the secretory VEGF-C level compared with IFN-β1a. Our investigation shows that both IFN-α2b and IFN-β1a exerted different antitumor and antimetastatic effects in human melanoma xenograft. Moreover, the present findings indicate that inhibition of lymphangiogenesis is another possible antimetastatic action mechanism of IFN-α2b.

Abstract
The prognosis of patients with many types of cancers correlates with the degree of metastasis to regional lymph nodes (LNs) and vital organs. However, the mechanisms and route of cancer cell metastasis are still unclear. Previous studies determined that B-cell accumulation in tumor-draining LNs (TDLNs) induces lymphatic sinus growth (lymphangiogenesis) and increases lymph flow, which could actively promote tumor dissemination through the lymphatic system. Using young Eµ-c-Myc mice that feature LN B-cell expansion as hosts for tumor transplants, we show that subcutaneously implanted lymphomas or melanomas preferentially spread to TDLNs over non-TDLNs, thus demonstrating that these tumors initially metastasize through lymphatic rather than through hematogenous routes. In addition, the rate and amount of tumor dissemination is greater in Eµ-c-Myc mice versus wild-type hosts, which correlates with LN B-cell accumulation and lymphangiogenesis in Eµ-c-Myc hosts. The increased lymphatic dissemination in Eµ-c-Myc hosts is further associated with rapid hematogenous tumor spread of subcutaneously implanted lymphomas, suggesting that TDLN metastasis secondarily drives lymphoma spread to distant organs. In contrast, after intravenous tumor cell injection, spleen metastasis of lymphoma cells or lung metastasis of melanoma cells is similar in Eµ-c-Myc and wild-type hosts. These studies demonstrate that the effect of Eµ-c-Myc hosts to promote metastasis is limited to the lymphatic route of dissemination. TDLN B-cell accumulation, in association with lymphangiogenesis and increased lymph flow, thus significantly contributes to dissemination of lymphomas and solid tumors, providing new targets for therapeutic intervention to block metastasis.

Abstract
Lymph node metastasis is a strong predictor of poor outcome in cancer patients. Animal studies of lymph node metastasis are constrained by difficulties in the establishment of appropriate animal models, limitations in the noninvasive monitoring of lymph node metastasis progression, and challenges in the pathologic confirmation of lymph node metastases. In this comprehensive review, we summarize available preclinical animal cancer models for noninvasive imaging and identification of lymph node metastases of non-hematogenous cancers. Furthermore, we discuss the strengths and weaknesses of common noninvasive imaging modalities used to identify tumor-bearing lymph nodes and provide guidelines for their pathological confirmation.

Constitutive expression of the alpha4 integrin correlates with tumorigenicity and lymph node metastasis of the B16 murine melanoma. Neoplasia 2010; 12:173-82.

Abstract
The lymphatic system plays a critical role in melanoma metastasis, and yet, virtually no information exists regarding the cellular and molecular mechanisms that take place between melanoma cells and the lymphatic vasculature. Here, we generated B16-F1 melanoma cells that expressed high (B16alpha(4)+) and negligible (B16alpha(4)-) levels of alpha(4) integrin to determine how the expression of alpha(4) integrins affects tumor cell interactions with lymphatic endothelial cells in vitro and how it impacts lymphatic metastasis in vivo. We found a direct correlation between alpha(4) integrin expression on B16-F1 melanoma cells and their ability to form adhesive interactions with monolayers of lymphatic endothelial cells. Adhesion of B16-F1 melanoma cells to lymphatic endothelial cells was mediated by the melanoma cell alpha(4) integrin binding to its counterreceptor, vascular cell adhesion molecule 1 (VCAM-1), that was constitutively expressed on the lymphatic endothelial cells. VCAM-1 was also expressed on the tumor-associated lymphatic vessels of B16-F1 and B16alpha(4)+ tumors growing in the subcutaneous space of C57BL/6J mice. B16-F1 tumors metastasized to lymph nodes in 30% of mice, whereas B16alpha(4)+ tumors generated lymph node metastases in 80% of mice. B16-F1 melanoma cells that were deficient in alpha(4) integrins (B16alpha(4)-) were nontumorigenic. Collectively, these data show that the alpha(4) integrin expressed by melanoma cells contributes to tumorigenesis and may also facilitate metastasis to regional lymph nodes by promoting stable adhesion of melanoma cells to the lymphatic vasculature.

Abstract
By definition, animal models provide only an approximation of clinical reality. One reason for this, for example, is that although metastases are the primary cause of mortality from neoplasia, by are rarely considered a target in drug discovery and development. Due to the impact of metastasis on clinical disease, we posit that metastasis should be considered in drug discovery, in addition, to more traditional biologic concepts, including drug pharmacology and toxicity. Drug discovery and developmental studies can incorporate orthotopic and spontaneous metastasis models (syngeneic and xenogeneic) with their inherent host-tumor microenvironmental interactions, in addition to confirmatory autochthonous and/or genetically engineered models (GEMs). This requires a rational and hierarchical approach using models of metastatic disease optimally using resected, orthotopic primary tumors and clinically relevant outcome parameters. In this chapter, we provide protocols for models of metastasis that can be used in translational and drug discovery studies.

Abstract
Lymphatic metastasis is the main prognostic factor for survival of patients with breast cancer and other epithelial malignancies. Mounting clinical and experimental data suggest that migration of tumor cells into the lymph nodes is greatly facilitated by lymphangiogenesis, a process that generates new lymphatic vessels from pre-existing lymphatics with the aid of circulating lymphatic endothelial progenitor cells. The key protein that induces lymphangiogenesis is vascular endothelial growth factor receptor-3 (VEGFR-3), which is activated by vascular endothelial growth factor-C and -D (VEGF-C and VEGF-D). These lymphangiogenic factors are commonly expressed in malignant, tumor-infiltrating and stromal cells, creating a favorable environment for generation of new lymphatic vessels. Clinical evidence demonstrates that increased lymphatic vessel density in and around tumors is associated with lymphatic metastasis and reduced patient survival. Recent evidence shows that breast cancers induce remodeling of the local lymphatic vessels and the regional lymphatic network in the sentinel and distal lymph nodes. These changes include an increase in number and diameter of tumor-draining lymphatic vessels. Consequently, lymph flow away from the tumor is increased, which significantly increases tumor cell metastasis to draining lymph nodes and may contribute to systemic spread. Collectively, recent advances in the biology of tumor-induced lymphangiogenesis suggest that chemical inhibitors of this process may be an attractive target for inhibiting tumor metastasis and cancer-related death. Nevertheless, this is a relatively new field of study and much remains to be established before the concept of tumor-induced lymphangiogenesis is accepted as a viable anti-metastatic target. This review summarizes the current concepts related to breast cancer lymphangiogenesis and lymphatic metastasis while highlighting controversies and unanswered questions.

Abstract
The interplay between canonical and non-canonical Wnt pathways in development and tumorigenesis is tightly regulated. In this review we will describe the yin and the yang of canonical and non-canonical Wnt signaling pathways during melanocyte development, and melanoma genesis. Canonical Wnt signaling, represented by Wnts such as Wnt1 and Wnt3A, signals via beta-catenin to promote melanocyte differentiation and tumor development. Non-canonical Wnt signaling, specifically Wnt5A, regulates canonical pathways, and signals to induce melanoma metastasis. This review will focus on the role of Wnt5A during melanoma progression, and its relationship to canonical Wnt signaling.

Abstract
There are currently no effective therapies for metastatic melanoma and targeted immunotherapy results in the remission of only a very small percentage of tumors. In this study, we show that the noncanonical Wnt ligand, Wnt5A, can increase melanoma metastasis in vivo while down-regulating the expression of tumor-associated antigens important in eliciting CTL responses (e.g., MART-1, GP100, and tyrosinase). Melanosomal antigen expression is governed by MITF, PAX3, and SOX10 and is inhibited upon signal transducers and activators of transcription 3 (STAT3) activation, via decreases in PAX3 and subsequently MITF expression. Increasing Wnt5A in Wnt5A-low cells activated STAT3, and STAT3 was decreased upon Wnt5A knockdown. Downstream targets such as PAX3, MITF, and MART-1 were also affected by Wnt5A treatment or knockdown. Staining of a melanoma tissue array also highlighted the inverse relationship between MART-1 and Wnt5A expression. PKC activation by phorbol ester mimicked Wnt5A effects, and Wnt5A treatment in the presence of STAT3 or PKC inhibitors did not lower MART-1 levels. CTL activation studies showed that increases in Wnt5A correspond to decreased CTL activation and vice versa, suggesting that targeting Wnt5A before immunotherapy may lead to the enhancement of current targeted immunotherapy for patients with metastatic melanoma.
