Abstract
The analysis of literature revealed that men experience uveal melanoma (UM) more frequently and with worse prognosis. There are also descriptions of an aggressive course of UM in pregnant women. These facts prompted researchers to analyze the effect of sex hormones and pregnancy on the development and progression of UM. Many years of international experience have refuted the presence of a reliable difference between 5-year survival and 5-year survival without metastases between non-pregnant women with UM and pregnant women with UM. That data is regarded as level 3 evidence. The experts have concluded that UM is not a contraindication to current or future pregnancy, and exogenous hormones (oral contraceptives or hormone replacement therapy) do not affect the incidence and prognosis of UM. Publications provide evidence of expression of the receptors of certain sex hormones (ER, ERRα, LH and LHRH) in primary UM, as well as overexpression of the ESR1 and ESR2 genes in UM with poor predictive characteristics. Overall AR mRNA expression in UM was low, but it was higher in epithelial UMs. The fact of expression of estrogen receptors in UM gives grounds to experiment with them as a target for therapy.

Abstract
BACKGROUND Despite a higher incidence and worse prognosis of uveal melanoma (UM) in men, there have been many case reports of pregnant patients with aggressive UM. This has led researchers to explore the influence of sex hormones and pregnancy on the development and progression of UM and hormones as potential therapeutic targets. SUMMARY A systematic literature review was conducted. More work is needed to elucidate the basis of sex differences in UM incidence and survival. The evaluation of germline BAP1 mutation would be beneficial in patients with UM presenting at a young age. Importantly, multiple studies reported no significant difference between the 5-year survival and 5-year metastasis-free survival rates between nonpregnant women with UM and pregnant women with UM. Multiple case-control studies disagree on how parity affects risk of UM. However, most studies agree that oral contraceptives and hormone replacement therapy have no effect on the incidence of UM. Current treatment strategies for pregnant patients with UM are discussed. Looking forward, this review reports recent research on targeted receptor-based chemotherapy, which is based on evidence of estrogen receptor (ER), estrogen-related receptor alpha (ERRα), and luteinizing hormone-releasing hormone (LHRH) receptor expression in UM. KEY MESSAGES Based on review of the literature, UM is not a contraindication to oral contraceptives, hormone replacement therapy, or pregnancy. Globe-sparing radiation can be used as a treatment option for pregnant patients. Due to the presence of ER on a subset of unselected UM, its potential for adjunctive targeted therapy with agents like tamoxifen should be explored. Lessons from cutaneous melanoma regarding tissue ratios of estrogen receptors (ERα:ERβ) should be applied to assess their therapeutic predictive value. In addition, ERRα-targeted therapeutics and LHRH analogs are worthy of further exploration in UM.

Abstract
The detailed molecular function of tumor microenvironment (TEM) in uveal melanoma (UVM) remains unclear. This study generated the immune index and the stromal index scores by ESTIMATE algorithm based on RNA-sequencing data with 80 UVM patients. There was no correlation between the immune stromal index and clinical parameters. The differentially expressed genes related to the immune stromal index were calculated and were described by functional annotations and protein-protein interaction network diagrams. After univariate and multivariate Cox regression analyses, there were four genes (HLA-J, MMP12, HES6, and ADAMDEC1) with significant prognostic significance. The prognostic model was constructed using these four characteristic genes, and the KM curve and tROC curve were described to show that the model had a better ability to predict survival outcomes and prognosis. The verification results in GSE62075 showed that HLA-J and HES6 were expressed differently in the cancer group than in the non-cancer group. This study indicates that the risk signature based on the immune index can be used as an indicator to evaluate the prognosis of patients with UVM.

Abstract
Simple Summary Melanoma is a very aggressive and fatal malignant tumor. While curable if diagnosed in its early stages, advanced melanoma, despite the complex therapeutic approaches, is associated with one of the highest mortality rates. Hence, more and more studies have focused on mechanisms that may contribute to melanoma development and progression. Various studies suggest a role played by neuroendocrine factors which can act directly on tumor cells, modulating their proliferation and metastasis capability, or indirectly through immune or inflammatory processes that impact disease progression. However, there are still multiple areas to explore and numerous unknown features to uncover. A detailed exploration of the mechanisms by which neuroendocrine factors can influence the clinical course of the disease could open up new areas of biomedical research and may lead to the development of new therapeutic approaches in melanoma. Abstract Melanoma is one of the most aggressive skin cancers with a sharp rise in incidence in the last decades, especially in young people. Recognized as a significant public health issue, melanoma is studied with increasing interest as new discoveries in molecular signaling and receptor modulation unlock innovative treatment options. Stress exposure is recognized as an important component in the immune-inflammatory interplay that can alter the progression of melanoma by regulating the release of neuroendocrine factors. Various neurotransmitters, such as catecholamines, glutamate, serotonin, or cannabinoids have also been assessed in experimental studies for their involvement in the biology of melanoma. Alpha-MSH and other neurohormones, as well as neuropeptides including substance P, CGRP, enkephalin, beta-endorphin, and even cellular and molecular agents (mast cells and nitric oxide, respectively), have all been implicated as potential factors in the development, growth, invasion, and dissemination of melanoma in a variety of in vitro and in vivo studies. In this review, we provide an overview of current evidence regarding the intricate effects of neuroendocrine factors in melanoma, including data reported in recent clinical trials, exploring the mechanisms involved, signaling pathways, and the recorded range of effects.

Abnormally expressed JunB transactivated by IL-6/STAT3 signaling promotes uveal melanoma aggressiveness via epithelial-mesenchymal transition. Biosci Rep 2018; 38:BSR20180532.

Abstract
Uveal melanoma (UM) is the most common primary intraocular tumor in adults, and it carries a high risk of metastasis and mortality. Various proinflammatory cytokines have been found to be significantly increased in the aqueous humor or vitreous fluid of UM patients; however, the role of these cytokines in UM metastasis remains elusive. In the present study, we found that long-term interleukin (IL)-6 exposure promoted the migration and invasion of UM cells, diminished cell–cell adhesion, and enhanced focal adhesion. Moreover, IL-6 treatment decreased the membranous epithelial marker TJP1 and increased the cytoplasmic mesenchymal marker Vimentin. Further investigation demonstrated that JunB played a critical role in IL-6-induced UM epithelial–mesenchymal transition (EMT). In UM cells, the expression of JunB was significantly up-regulated during the IL-6-driven EMT process. Additionally, JunB induction occurred at the transcriptional level in a manner dependent on phosphorylated STAT3, during which activated STAT3 directly bound to the JunB promoter. Importantly, the knockdown of STAT3 prevented the IL-6-induced EMT phenotype as well as cell migration and invasion, whereas JunB overexpression recovered the attenuated aggressiveness of UM cells. Similarly, with IL-6 stimulation, the stable overexpression of JunB strengthened the migratory and invasive capabilities of UM cells and induced the EMT-promoting factors (Snail, Twist1, matrix metalloproteinase (MMP)-2, MMP-14, and MMP-19). Analysis of The Cancer Genome Atlas (TCGA) database indicated that JunB was positively correlated with IL-6 and STAT3 in UM tissues. The present study proposes an IL-6/STAT3/JunB axis leading to UM aggressiveness by EMT, which illustrates the negative side of inflammatory response in UM metastasis.

Use of a Tissue Engineered Human Skin Model to Investigate the Effects of Wounding and of an Anti-Inflammatory on Melanoma Cell Invasion. PLoS One 2016; 11:e0156931.

Abstract
An increasing number of studies suggest inflammation stimulates tumour invasion. In melanoma, despite recent advances in targeted therapy and immunomodulatory therapies, this cancer remains difficult to treat. Our previous studies show melanoma cells interact with skin cells in their invasion into tissue engineered skin and suggest inflammation stimulates invasion. The aim of this study was to investigate the use of an anti-inflammatory on melanoma invasion. To do this we developed a wounded and inflamed in vitro 3D melanoma model in which to investigate the use of an anti-inflammatory on melanoma invasion. The tissue engineered skin model was based on human de-epidermised acellular dermis to which keratinocytes, fibroblasts and three different melanoma cell lines were added in various combinations. A simple incisional wound was made in the model and TNF-α and fibrin were added to simulate conditions of inflammation. Topical ibuprofen in a hydrogel was added and the extent of melanoma invasion into the dermis was assessed under the various conditions. The results showed that penetration of two of the cell lines (HBL and A375SM) into the tissue engineered skin was exacerbated by wounding and ibuprofen significantly decreased invasion of A375SM cells and slightly reduced invasion of HBL cells. A third cell line, C8161, was aggressively invasive under all conditions to an extent that was not influenced by wounding, TNF-α or the addition of ibuprofen. In summary, the results for one these cell lines (and a trend for a second cell line) support the hypothesis that a wound environment is conducive to melanoma invasion but the local addition of an anti-inflammatory drug such as ibuprofen may attenuate invasion.

Abstract
OBJECTIVE To describe the progression of uveal melanocytic lesions to melanomas after initiation of tumor necrosis factor-α (TNF-α) inhibitors. PATIENTS AND METHODS We report 3 cases of uveal melanoma occurring after treatment with TNF-α inhibitors, 2 from Mayo Clinic and 1 from Yale University. The study took place from February 27, 2009, through July 15, 2013. RESULTS Two women and one man with inflammatory disease who received TNF-α inhibitors had subsequent development of uveal melanomas. The 2 women had inflammatory bowel disease and had been followed up for melanocytic tumors that grew markedly within 1 year after beginning treatment with TNF-α inhibitors to the point of requiring treatment. One had histologic confirmation of the melanoma. The male patient had rheumatoid arthritis that was being treated with TNF-α inhibitors. Serial ultrasonography was performed to monitor bilateral diffuse scleritis, and within 16 months of initiation of TNF-α inhibitor therapy, a choroidal mass was detected that continued to grow over the next 3 months. The patient elected to have enucleation, which revealed uveal melanoma and thinning of the sclera from the previous scleritis. CONCLUSION Our 3 cases of uveal melanocytic tumors occurring after the use of TNF-α inhibitors add to the growing literature suggesting a correlation between TNF-α inhibitors and the development of malignant neoplasms. Considering the association between cutaneous melanoma and TNF-α inhibitors, we recommend that patients have an eye examination before initiation of TNF-α inhibitors, and those with preexisting nevi should be followed up at regular intervals.

Elevation of intracellular cyclic AMP inhibits NF-kappaB-mediated thymosin beta4 expression in melanoma cells. Exp Cell Res 2009; 315:3325-35.

Abstract
Thymosin beta4 (Tbeta4) is a major actin-sequestering protein that has been implicated in the growth, survival, motility, and metastasis of certain tumors and is considered an indicator for malignant progression. Therefore, identifying compounds that can downregulate Tbeta4 expression is very important for the development of anti-cancer chemotherapies. In this study, we investigated the effects of elevated cAMP on Tbeta4 expression and the metastatic potential of murine B16 melanoma cells. In addition, we also dissected the mechanism underlying cAMP-mediated Tbeta4 suppression. We found that treatment with the cAMP-inducing compounds alpha-MSH (alpha-melanocyte stimulating hormone) and IBMX (3-isobutyl-1-methylxanthine) significantly suppressed Tbeta4 expression and regulated EMT-associated genes through the suppression of NF-kappaB activation in B16F10 cells. Along with decreased Tbeta4 expression, the in vitro invasiveness and anchorage-independent growth in a semi-solid agar of these cells were also inhibited. In animal experiments, the metastatic potential of the alpha-MSH- or IBMX-treated B16F10 melanoma cells was decreased compared to untreated control cells. Collectively, our data demonstrate that elevated intracellular cAMP significantly suppresses Tbeta4 expression and reduces MMP-9 activity, which leads to decreased metastatic potential. Moreover, suppression of NF-kappaB activation by alpha-MSH or IBMX is critical for inhibiting Tbeta4 expression.

Abstract
BACKGROUND There is growing evidence that inflammation may exacerbate cancer metastasis and several clinical studies show that taking nonsteroidal anti-inflammatory drugs appears to reduce metastases. OBJECTIVES The aims of this study were: (i) to examine the effects of ibuprofen on the major proinflammatory cytokine tumour necrosis factor (TNF)-alpha induction of migration of C8161 and HBL human melanoma cells; (ii) to develop ibuprofen-releasing hydrogels (Pluronics F127) for future topical use in reducing metastatic spread of primary melanoma; and (iii) to examine whether the actions of ibuprofen might be explained by induction of apoptosis. METHODS Melanoma cells were exposed to 300 U mL(-1) TNF-alpha for a 24-h period prior to making a scratch wound to which ibuprofen or ibuprofen-loaded hydrogels were then added. The effects of relevant concentrations of ibuprofen on cell viability and apoptosis were examined. RESULTS Ibuprofen at 10(-3) mol L(-1) significantly reduced TNF-alpha-stimulated migration of both cell types to that of nonstimulated cells (P < 0.001). TNF-alpha-unstimulated cell migration was not significantly affected. Cells responded similarly to SS and SR forms of ibuprofen. Cells treated with ibuprofen sodium salt-loaded hydrogels showed a significant reduction in migration when compared with unloaded hydrogels. Ibuprofen induced apoptosis in HBL cells but had no effect on C8161 melanoma cells apoptosis at concentrations that reduced migration. CONCLUSIONS These results demonstrate that TNF-alpha upregulated malignant melanoma migration in vitro and that this could be reduced by ibuprofen both in solution and delivered from a hydrogel. These effects of ibuprofen cannot be attributed simply to induction of apoptosis.

Abstract
BACKGROUND Uveal melanomas of the choroid and ciliary body are aggressive tumors causing the death of approximately 50% of patients. In contrast, iris melanomas only infrequently metastasize; why these differences exist is not known. The local environment can regulate cancer growth and development, and it is probable the aqueous and vitreous humors have an important role in regulating uveal melanoma behavior. METHODS To explore this possibility cultures of uveal melanoma were exposed to aqueous and vitreous and the effects investigated using invasion and proliferation assays. ChemiArrays (Chemicon International, Temecula, Calif) were performed to determine which regulatory factors might influence the process. RESULTS The vitreous universally promoted uveal melanoma invasion, whereas the aqueous mainly had no effect or was inhibitory. Tumor location, and the baseline invasion of the melanoma, affected the ability of aqueous and vitreous from different patients to regulate invasive behavior. Proliferation was not significantly altered as a result of exposure to the aqueous or vitreous. The ability of the humors to regulate uveal melanomas may involve TIMP-2, TIMP-3, and TGF-beta2, as high expression was found by ChemiArray analysis and there were differences in the levels of the regulators in the aqueous compared with the vitreous. CONCLUSIONS The findings suggest that in situ uveal melanoma development reflects an interaction between the tumor and the environment of the eye. Exposure to the aqueous would therefore contribute to the benign nature of iris melanomas, whereas potential interaction with the vitreous appears to promote the aggressive behavior of posterior uveal melanomas.

Abstract
Melanoma is a malignant skin cancer that displays a high rate of tumor cell migration and metastasis. This study examined how corticotropin-releasing hormone (CRH) affects the migration of melanoma cells in order to further understand the relationship between stress and tumor cell migration. The migration assay data showed that CRH treatment increased the level of B16F10 cell migration in a dose- and time-dependent manner. To determine whether the extracellular signal-regulated protein kinase 1/2 (ERK1/2) signaling pathway is involved in the upregulation of melanoma migration, cells were pretreated with an inhibitor of ERK1/2 (PD098059). The pretreatment of PD098059 blocked the increase in cell migration. Furthermore, CRH induced the phosphorylation of ERK1/2. The maximum activation of ERK1/2 by CRH was observed at 15 min. Taken together, these results suggest that CRH is an important mediator that regulates the migration of melanoma cells in the skin during stress through the ERK1/2 signaling pathway.

Abstract
We have previously shown that tumour necrosis factor-alpha (TNF-alpha) upregulates human melanoma cell integrin expression, migration and invasion in vitro. The aim of this study was to investigate the effect of the non-steroidal anti-inflammatory agent sodium salicylate on TNF-alpha-induced activation of the transcription factor nuclear factor-kappaB (NF-kappaB) and upregulation of intercellular adhesion molecule-1 (ICAM-1), and TNF-alpha-stimulated cell migration and invasion through fibronectin. HBL human melanoma cells were pre-incubated with sodium salicylate prior to stimulation with TNF-alpha for 24 h. NF-kappaB activation was measured using an assay that detects changes in the expression of a luciferase reporter gene under the direct control of NF-kappaB transcriptional activity. The effect of sodium salicylate and TNF-alpha on HBL cell invasion over 20 h and migration over 24 h was studied using fibronectin invasion and 'scratch wound' migration models in vitro, as described previously. Sodium salicylate inhibited TNF-alpha-stimulated NF-kappaB activation in melanoma cells in a concentration-dependent manner, and this was achieved with pre-incubation times as short as 15 min. TNF-alpha-stimulated ICAM-1 expression in HBL cells was also downregulated by sodium salicylate, although in a manner inversely related to the concentration of this agent. In functional assays, TNF-alpha stimulated migration and invasion, and sodium salicylate significantly reduced the extent of melanoma invasion and migration in both the presence and absence of TNF-alpha. In conclusion, sodium salicylate effectively inhibited TNF-alpha-induced upregulation of NF-kappaB, ICAM-1 expression, in-vitro migration and invasion in human melanoma cells, indicating that non-steroidal anti-inflammatory drugs may be a useful therapeutic approach to oppose inflammation-induced melanoma invasion and metastasis in vivo.

Abstract
Alpha-melanocyte stimulating hormone (alpha-MSH) arises from the proteolytic cleavage of proopiomelanocortin (POMC) and is the most potent naturally occurring melanotropic peptide. The biological effects of alpha-MSH are mediated via melanocortin receptors (MCRs), which are expressed in virtually every cutaneous cell type. alpha-MSH has pleiotrophic functions including the modulation of a wide range of inflammatory stimuli such as proinflammatory cytokines, adhesion molecules and inflammatory transcription factors. All of the former would be consistent with a cytoprotective role for this hormone in protecting skin cells from exogenous stress, as would occur following UV exposure or exposure to agents inducing inflammation or oxidative stress. In addition to actions on normal skin cells it also modulates both cutaneous and uveal melanoma cell behavior. With respect to melanoma, alpha-MSH is intriguing as studies have shown that while alpha-MSH has the potential to retard metastatic spread (by reducing cell migration and invasion) it is also capable of reducing the ability of the immune system to detect tumor cells (by down regulating adhesion molecules that would normally assist in immune cell interaction with melanoma cells). This review considers the evolving biology of alpha-MSH and discusses its role in man that extend far beyond pigmentation of skin melanocytes, suggesting that the detoxifying role of alpha-MSH in inducing melanogenesis is only one aspect of the stress-coping role of this hormone. Indeed melanoma cells may owe at least some of their success to the 'protective' role of alpha-MSH.

Abstract
Cell differentiation, proliferation, apoptosis, and cell motility are induced and regulated by a host of growth factors, vitamins, and hormones. The mode of function of these modifiers of biological response, the signaling pathways that they activate, and the interacting pathways that can influence the biological outcome have been the focus of attention. Especially recognized and discussed in this review is the deregulation of their function, leading to abnormalities in cell proliferation, alteration of intercellular adhesive cohesion, remodeling of the extracellular matrix, and invasive behavior and metastatic deposition that are so characteristic of tumor development and progression, which strongly underscores the concept of molecular progression of cancer constructed on the basis of the relationship between genetic changes and the biological events associated with cancer progression. The molecular changes associated with hormone- and vitamin-driven responses and the deregulation of the expression and function of their target genes seem to correlate with specific biological events linked with cancer invasion and progression, and these findings could lead to the establishment of new markers of progression and to the development of new strategies for patient management. The scope of this work has been restricted by design and is dictated by the field of interest of the author's laboratory, but it is hoped that this field would be regarded adequately to reflect the wide genre of scientific interest in this field of human disease.

Abstract
Pro-opiomelanocortin (POMC) is a prohormone of various neuropeptides, including corticotropin, alpha-melanocyte-stimulating hormone (alpha-MSH), and beta-endorphin (beta-EP). POMC neuropeptides are potent inflammation inhibitors and immunosuppressants and may exert opposite influences during tumorigenesis. However, the role of POMC expression in carcinogenesis remains elusive. We evaluated the antineoplastic potential of POMC gene delivery in a syngenic B16-F10 melanoma model. Adenovirus-mediated POMC gene delivery in B16-F10 cells increased the release of POMC neuropeptides in cultured media, which differentially regulated the secretion of pro- and anti-inflammatory cytokines in lymphocytes. POMC gene transfer significantly reduced the anchorage-independent growth of melanoma cells. Moreover, pre- or post-treatment with POMC gene delivery effectively retarded the melanoma growth in mice. Intravenous injection of POMC-transduced B16-F10 cells resulted in reduced foci formation in lung by 60 to 70% of control. The reduced metastasis of POMC-transduced B16-F10 cells could be attributed to their attenuated migratory and adhesive capabilities. POMC gene delivery reduced the cyclooxygenase-2 (COX-2) expression and prostaglandin (PG) E(2) synthesis in melanoma cells and tumor tissues. In addition, application of NS-398, a selective COX-2 inhibitor, mimicked the antineoplastic functions of POMC gene transfer in melanoma. The POMC-mediated COX-2 down-regulation was correlated with its inhibition of nuclear factor kappaB (NFkappaB) activities. Exogenous supply of alpha-MSH inhibited NFkappaB activities, whereas application of the alpha-MSH antagonist growth hormone-releasing peptide-6 (GHRP-6) abolished the POMC-induced inhibition of NFkappaB activities and melanoma growth in mice. In summary, POMC gene delivery suppresses melanoma via alpha-MSH-induced inhibition of NFkappaB/COX-2 pathway, thereby constituting a novel therapy for melanoma.

Abstract
Inflammatory mediators have been reported to promote malignant cell growth, invasion and metastatic potential. More specifically, we have recently reported that tumour necrosis factor alpha (TNF-alpha) increases melanoma cell attachment to extracellular matrix (ECM) substrates and invasion through fibronectin. In this study, we extend these investigations asking specifically whether the TNF-alpha effect on cell invasion and migration involves activation of proteolytic enzymes. We examined the effect of TNF-alpha on melanoma expression/activation of type IV gelatinases matrix metalloproteinases 2 and 9 (MMPs -2 and -9) and general proteolytic enzymes. Stimulation with TNF-alpha significantly increased both melanoma cell migration at 24 h (+21%) and invasion through fibronectin (+35%) but did not upregulate/activate the expression of latent MMP-2 constitutively produced by these cells and did not upregulate their general protease activity. However, the increased cell migration and invasion through fibronectin observed following stimulation with TNF-alpha were inhibited by the general protease inhibitor alpha(2) macroglobulin. These findings suggest that the promigratory and proinvasive effect of TNF-alpha on this melanoma cell line may be mediated to some extent by induction of localised cell membrane-bound degradative enzyme activity, which is not readily detected in biochemical assays.
