HDAC2 Is Involved in the Regulation of BRN3A in Melanocytes and Melanoma.

The neural crest transcription factor BRN3A is essential for the proliferation and survival of melanoma cells. It is frequently expressed in melanoma but not in normal melanocytes or benign nevi. The mechanisms underlying the aberrant expression of BRN3A are unknown.

The myelin protein PMP2 is regulated by SOX10 and drives melanoma cell invasion.

The transcription factor sex determining region Y-box 10 (SOX10) plays a key role in the development of melanocytes and glial cells from neural crest precursors. SOX10 is involved in melanoma initiation, proliferation, invasion, and survival. However, specific mediators which impart its oncogenic properties remain widely unknown.

Inhibition of histone deacetylases in melanoma-a perspective from bench to bedside.

Histone deacetylases (HDACs) are critically involved in epigenetic gene regulation through alterations of the chromatin status of DNA. Aberrant expression, dysregulation of their enzymatic activity or imbalances between HDACs and histone acetyltransferases are likely involved in the development and progression of cancer. Pharmacologic inhibition of HDACs shows potent antitumor activity in a panel of malignancies such as colon or gastric cancer and multiple myeloma.

The Systemic Management of Advanced Melanoma in 2016.

Melanoma is a common type of skin cancer with a high propensity to metastasize. Tyrosine kinase inhibitors targeting the mitogen-activated protein kinase (MAPK) pathway and immune checkpoint blockade have recently revolutionized the management of unresectable and metastatic disease. However, acquired resistance and primary non-response to therapy require novel treatment strategies and combinations.

A Bifunctional Approach of Immunostimulation and uPAR Inhibition Shows Potent Antitumor Activity in Melanoma.

Significant advancements of mutation-based targeted therapy and immune checkpoint blockade have been achieved in melanoma. Nevertheless, acquired resistance and nonresponders to therapy require different strategies. An innovative approach is presented here that is based on the combination of innate immune system activation and simultaneous targeting of the oncogene urokinase-type plasminogen activator receptor (uPAR).

Combination therapy of melanoma using kinase inhibitors.

Purpose Of Review: Treatment options for metastatic melanoma depend on the clinical course of the disease and the molecular profile such as mutations of the BRAF gene. In this article, we review the current state of targeted therapy with kinase inhibitors.

Recent Findings: Despite major advancements in targeted therapy of metastatic melanoma, most patients relapse and show progressive disease after 5-7 months with single inhibition of BRAF or MEK.

SOX10 promotes melanoma cell invasion by regulating melanoma inhibitory activity.

The transcription factor SOX10 (SRY (sex determining region Y)-box 10) has a key role in the embryonic development of melanocytes. Recently, it has been suggested that SOX10 is highly relevant for melanoma development and survival. However, the distinct functions and downstream targets of SOX10 in melanoma remain widely unknown.

The neural crest transcription factor Brn3a is expressed in melanoma and required for cell cycle progression and survival.

Pigment cells and neuronal cells both are derived from the neural crest. Here, we describe the Pit-Oct-Unc (POU) domain transcription factor Brn3a, normally involved in neuronal development, to be frequently expressed in melanoma, but not in melanocytes and nevi. RNAi-mediated silencing of Brn3a strongly reduced the viability of melanoma cell lines and decreased tumour growth in vivo.

Selective induction of cell death in melanoma cell lines through targeting of Mcl-1 and A1.

Melanoma is an often fatal form of skin cancer which is remarkably resistant against radio- and chemotherapy. Even new strategies that target RAS/RAF signaling and display unprecedented efficacy are characterized by resistance mechanisms. The targeting of survival pathways would be an attractive alternative strategy, if tumor-specific cell death can be achieved.
