(University of Turku) New study from researchers in Finland and the United Kingdom reveals that tumors lacking a protein called BAP1 have an ineffective immune reaction against cancer, thus rendering immunotherapies ineffectual, particularly in uveal melanomas (UM). The researchers also discovered that when BAP1 is lost, other molecules will be present in order to support cancer growth. Luckily, some of these molecules can be targeted with existing drugs, which can lead to the development of novel immunotherapies.

CONCLUSIONS: Neurological involvement in MM encompasses a myriad of variants and while the clinical setting varies from one patient to another, an underlining neoplasia should be evaluated in suspected patients. PMID: 32239096 [PubMed - in process]

Carmona-Sáez Rodríguez-Manzaneque Extracellular matrix remodeling within the tumor microenvironment has been recognized as a relevant dynamic framework during tumor growth. However, research on proteases that trigger this remodeling keeps revealing a wide range of actions including both pro- and anti-tumorigenic. The extracellular protease ADAMTS1 exemplifies this dual role. In this work, we first confirmed a positive correlation of ADAMTS1 with endothelial-like phenotype of human melanoma cells together with the finding of associated signatures, including key genes such as endothelial CDH5. Using a C...

ris Behrmann Stephanie Kreis Reduced levels of intratumoural oxygen are associated with hypoxia-induced pro-oncogenic events such as invasion, metabolic reprogramming, epithelial–mesenchymal transition, metastasis and resistance to therapy, all favouring cancer progression. Small extracellular vesicles (EV) shuttle various cargos (proteins, miRNAs, DNA and others). Tumour-derived EVs can be taken up by neighbouring or distant cells in the tumour microenvironment, thus facilitating intercellular communication. The quantity of extracellular vesicle secretion and their composition can vary with changing microe...

B. Ewa Snaar-Jagalska The ruthenium-based photosensitizer (PS) TLD1433 has completed a phase I clinical trial for photodynamic therapy (PDT) treatment of bladder cancer. Here, we investigated a possible repurposing of this drug for treatment of conjunctival melanoma (CM). CM is a rare but often deadly ocular cancer. The efficacy of TLD1433 was tested on several cell lines from CM (CRMM1, CRMM2 and CM2005), uveal melanoma (OMM1, OMM2.5, MEL270), epidermoid carcinoma (A431) and cutaneous melanoma (A375). Using 15 min green light irradiation (21 mW/cm2, 19−2, 520 nm), the highest phototherapeutic index (PI)...

ndrzej Marszałek Uveal melanoma (UM) is the most common primary tumor of the eye diagnosed in adults, associated with a high risk of metastasis and thereby, poor prognosis. Among known risk factors for the development of metastatic disease is the loss of BAP1 expression and chromosome 3 monosomy in the primary tumor. However, the expression levels of specific micro RNAs (miRNA) in tumor tissue may also serve as a valuable marker for determining the risk of metastatic disease in patients with primary uveal melanoma. In our study, we analyzed the miRNA expression data of cases selected from The Cancer Genome Atlas study...
