Special Issue Information

Dear Colleagues,

The excessive proliferation of cells and turnover of the cellular matrix contribute significantly to the pathogenesis of several diseases, including cancer, atherosclerosis, rheumatoid arthritis, psoriasis, idiopathic pulmonary fibrosis, pulmonary hypertension, scleroderma and cirrhosis of the liver. The mechanisms that control the spread of damage in these types of pathologies are not entirely clear. In recent years, interest in the different types of extracellular vesicles (exosomes, microvesicles, apoptotic bodies or newly identified subpopulations such as oncosomes, migrasomes, exophers, etc.) and their roles as mediators of intercellular and interorgan communication has increased exponentially. Extracellular vesicles (EVs) are nanosized lipid membrane-enclosed vesicles that may contain nucleic acids (DNAs, mRNAs, miRNAs, lncRNAs, piRNAs, etc.), lipids, proteins and organelles and may participate in the dissemination of the proliferative phenotype or in the possible therapeutic effects of these types of pathologies.

In this Special Issue, we aim to highlight the role of extracellular vesicles in proliferative diseases. Therefore, we invite researchers to contribute original research and up-to-date review articles that increase knowledge about the mechanisms involved in the synthesis, cargo or internalization of these vesicles. We also welcome articles that explore their use as biomarkers.

Platinum-resistant high-grade serous carcinoma (HGSC) is an incurable disease, so biomarkers that could help with timely treatment adjustments and personalized approach are extensively being sought. Tumor-derived extracellular vesicles (EVs) that can be isolated from ascites and blood of HGSC patients are such promising biomarkers. Epithelial cell adhesion molecule (EpCAM) expression is upregulated in most epithelium-derived tumors; however, studies on prognostic value of EpCAM overexpression in ovarian carcinoma have shown contradictory results. The aim of our study was to evaluate the potential of total and EpCAM-positive EVs as prognostic and predictive biomarkers for advanced HGSC. Flow cytometry was used to determine the concentration of total and EpCAM-positive EVs in paired pretreatment ascites and plasma samples of 37 patients with advanced HGSC who underwent different first-line therapy. We found that higher EpCAM-positive EVs concentration in ascites is associated with shorter progression-free survival (PFS) regardless of treatment strategy. We also found a strong correlation of EpCAM-positive EVs concentration between ascites and plasma. Our findings indicate that EpCAM-positive EVs in ascites of patients with advanced HGSC have the potential to serve as prognostic biomarkers for predicting early recurrence and thereby likelihood of more aggressive tumor biology and development of chemoresistance.

Breast cancer is the most common cancer amongst women worldwide. Recently, owing to screening programs and new technologies, the survival rate has increased significantly. Breast cancer can potentially develop metastases, and, despite them, lung metastases generally occur within five years of breast cancer diagnosis. In this study, the objective was to analyze the effect of breast cancer-derived EVs on a lung epithelial cell line. BEAS-2B cells were treated with extracellular vesicles (EVs) derived from triple-negative breast cancer cells (TNBCs), e.g., MDA-MB-231 and HS578T, separated using differential ultracentrifugation. We observed an increased growth, migration, and invasiveness of normal epithelial lung cells over time in the presence of TNBC EVs compared to the control. Therefore, these data suggest that EVs released by tumor cells contain biological molecules capable of influencing the pro-tumorigenic activity of normal cells. Exploring the role of EVs in oncology research and their potential cargo may be novel biomarkers for early cancer detection and further diagnosis. Full article
