PURPOSE IL2 inducible T-cell kinase (ITK) promoter CpG sites are hypomethylated in melanomas compared with nevi. The expression of ITK in melanomas, however, has not been established and requires elucidation. EXPERIMENTAL DESIGN An ITK-specific monoclonal antibody was used to probe sections from deidentified, formalin-fixed paraffin-embedded tumor blocks or cell line arrays and ITK was visual...
Purpose: IL2 inducible T-cell kinase (ITK) promoter CpG sites are hypomethylated in melanomas compared with nevi.

We have previously shown that the mRNA binding protein CRD-BP is overexpressed in human melanomas, where it promotes cell survival and resistance to chemotherapy. The present study investigates the role of hypoxia, a common characteristic of the tumor microenvironment, in the regulation of CRD-BP expression and melanoma cell responses. We found that hypoxia increases CRD-BP levels in metastatic...
Organotropism of cancer metastasis is driven by the ‘seed and soil’ theory where soil (metastatic microenvironment) provides signals to attract seeds (cancer cells) grow on a certain location. S100A8/A9 ‘soil sensing signal’ that binds receptors expressed many types. We aimed understand role in melanoma, breast lung cancer, develop neutralizing antibody, provide proof-of-concept for antibody in...
Background Advanced melanoma is associated with a poor prognosis. Targeted therapy and immunotherapy are mainstays of treatment. High-dose interleukin-2 (HD IL-2), interferon alfa-2b, cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) inhibitors, and programmed cell death protein 1 (PD-1) inhibitors are approved immunotherapies. Genetically engineered T cells targeting melanoma antigens are c...
Previous studies from our laboratory have identified several endothelial cell-associated marker genes implicated in human melanoma metastasis via tumor vasculogenic mimicry. In this study, we used dual model systems composed of melanoma cell lines and clinical melanoma samples to validate the importance of insulin-like growth factor binding protein-3 (IGFBP-3) as a marker involved in disease pr...
Protein arginine methyltransferase-5 (PRMT5) is a Type II arginine methyltransferase that regulates various cellular functions. We hypothesized that PRMT5 plays a role in regulating the growth of human melanoma cells. Immunohistochemical analysis indicated significant upregulation of PRMT5 in human melanocytic nevi, malignant melanomas and metastatic melanomas as compared to normal epidermis. F...
Cytochalasin D (CytD) targets actin, a ubiquitous protein in eukaryotic cells. Previous studies have focused mainly on the antitumor effects of CytD. We previously found CytD to promote lung metastasis in B16 melanoma cells, which we had not anticipated, and, therefore, in the present study we investigated the possible underlying mechanisms. B16 melanoma cells were co-cultured with CytD and oth...
Metastatic melanomas are typically resistant to radiation and chemotherapy. The underlying basis for this phenomenon may result in part from defects in apoptotic pathways. Nuclear factor kappa B (NFkappaB) has been shown to control apoptosis in many cell types and normally functions as an immediate stress response mechanism that is rigorously controlled by multiple inhibitory complexes. We have...
BACKGROUND Melanoma metastasis status is highly associated with the overall survival of patients; yet, little is known about proteomic changes during melanoma tumor progression. To better understand the changes in protein expression involved in melanoma progression and metastasis, and to identify potential biomarkers, we conducted a global quantitative proteomic analysis on archival metastatic ...
