Flotillin 2 (flot-2) is a highly conserved protein isolated from caveolae/lipid raft domains that tether growth factor receptors linked to signal transduction pathways. Flot-2 protein and mRNA were increased in tumorigenic and metastatic melanoma cell lines in vitro, and the immunostaining intensity increased substantially across a tissue array of melanocytic lesions. Flot-2 transfection transf...
Espin is a multifunctional actin-bundling protein withmultiple isoforms, and has special connections to hair cell stereocilia and microvillar specializations of sensory cells in the inner ear. However, there have been no reports showing the expression and function of Espin in cancers, including melanoma. Here, it is demonstrated that Espin expression is significantly increased in melanomas that...
Here, we report the molecular regulation of interleukin (IL)-8 expression in human melanoma cells. The inflammatory cytokines IL-1beta and tumor necrosis factor-alpha (TNF-alpha) up-regulated IL-8 expression, in a time- and concentration-dependent manner, in three metastatic melanoma variants, SBC-2 (nonmetastatic), A375P (low metastatic), and A375SM (high metastatic), by increased transcriptio...
PURPOSE RUNX3 is a known tumor suppressor gene in several carcinomas. Aberration in RUNX3 expression has not been described for cutaneous melanoma. Therefore, we assessed the expression of RUNX3 in cutaneous melanoma and its regulatory mechanisms relative to tumor progression. EXPERIMENTAL DESIGN The expression of RUNX3 mRNA and miR-532-5p (microRNA) was assessed in melanoma lines and in prim...
Melanoma incidence and survival are age-dependent, with older patients having both higher rates worse outcomes. Here, we seek to examine age-dependent differences in mutational profiles of cutaneous melanoma, which may impact melanoma prognosis treatment-related Mutational 2263 were extracted from the American Association for Cancer Research Project Genomics Evidence Neoplasia Information Excha...
L Antigen Family Member 3 (LAGE3) is an important RNA modification-related protein. Whereas few studies have interrogated the LAGE3 protein, there limited data on its role in tumors. Here, we analyzed and profiled protein skin cutaneous melanoma (CM) using TCGA, GTEx, or GEO databases. Our showed upregulation of cell lines compared to normal lines. Besides, Kaplan–Meier curves Cox proportional ...
The incidence of cutaneous malignant melanoma in the United States has increased more than any other cancer in recent years. Chemotherapy for metastatic melanoma is disappointing, there being anecdotal cases of complete remission. Dacarbazine (DTIC) is considered the gold standard for treatment, having a response rate of 15-20%, but most responses are not sustained. The mechanisms for the incre...
mda-9/Syntenin is a scaffolding PDZ domain-containing protein overexpressed in multiple human cancers that functions as a positive regulator of melanoma metastasis. Using a normal immortal human melanocyte cell line and weakly and highly metastatic human melanoma cell lines, we presently show that mda-9/syntenin initiates a signaling cascade that activates nuclear factor-kappaB (NF-kappaB) in h...
BACKGROUND The loss of AP-2alpha and increased activity of cAMP-responsive element binding (CREB) protein are two hallmarks of malignant progression of cutaneous melanoma. However, the molecular mechanism responsible for the loss of AP-2alpha during melanoma progression remains unknown. METHODOLOGY/PRINCIPAL FINDINGS Herein, we demonstrate that both inhibition of PKA-dependent CREB phosphoryl...
Despite recent advances in targeted therapies and immunotherapies metastatic melanoma remains only rarely curable. The objective of the present study was to identify novel therapeutic targets for metastatic melanoma. A library of 160 well-characterised and potent protein kinase inhibitors was screened in the BRAF mutant cell line Sk-Mel-28, and the NRAS mutant Sk-Mel-2, using proliferation assa...
