Conclusions: It has been proven in few recent preclinical and clinical studies (mainly multiple myeloma, isolated solid tumors including lung cancer) that 68Ga-Pentixafor uptake is tied up specifically to CXCR 4 expression. The results of this preliminary study demonstrate that 68Ga-Pentixafor PET imaging in GBM (know to have high CXCR4 expression) is viewed to open-up new theranostics applications (with beta and alpha radionuclides) for long term survival benefits. However, the diagnostic utility of this tracer needs to be validated in a large cohort of patients through multi-centric trials.

AbstractPurposeMetastatic non-small cell lung (NSCLC) cancer represents one of the most common types of brain metastasis. The mechanisms involved in how circulating cancer cells transmigrate into brain parenchyma are not fully understood. The aim of this work was to investigate the role of fucosylated carbohydrate epitopes CD15 and sialyated CD15s in cancer adhesion to brain-derived endothelial cells and determine their influence in blood –brain barrier (BBB) disruptionMethodsThree distinct, independent methods were used to measure brain endothelial integrity and include voltohmmeter (EVOM ™), impedance spectro...

This study aimed to explore novel biomarkers for GBM prognosis prediction. The gene expression profiles from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) datasets of GBM were downloaded. A total of 2241 overlapping differentially expressed genes (DEGs) were identified from TCGA and GSE7696 datasets. By univariate COX regression survival analysis, 292 survival-related genes were found among these DEGs (p

Ott Research Institute of Obstetrics, Gynecology and Reproductology, Saint Petersburg, Russia 2Department of Genetics and Biotechnology, Saint Petersburg State University, Saint Petersburg, Russia In the present review, we focus on the phenomenon of chromothripsis, a new type of complex chromosomal rearrangements. We discuss the challenges of chromothripsis detection and its distinction from other chromoanagenesis events. Along with already known causes and mechanisms, we introdu...

In this study, to improve our understanding of the role of ATP1A1 in the malignant phenotype and pathogenesis of GSCs, we evaluated ATP1A1 expression in GBMs of different grades and in two primary GSC lines established from human GBM tissues. We evaluated the role of ATP1A1 in GSC growth, its interactions with Src, and the activation of the ERK1/2 and AKT pathways. Our results revealed that ATP1A1 acts as an oncogene in our GSC models and targeting ATP1A1/Src may suppress GSC proliferation and growth. Materials and Methods Cell Isolation and Culture Human brain GBM tissues were from pathologically confirmed surgical spe...

Conclusions This review describes how leukocyte-heparanase can be a double-edged sword in tumor progression; it can enhance tumor immune surveillance and tumor cell clearance, but also promote tumor survival and growth. We also discuss the potential of using heparanase in leukocyte therapies against tumors, and the effects of heparanase inhibitors on tumor progression and immunity. We are just beginning to understand the influence of heparanase on a pro/anti-tumor immune response, and there are still many questions to answer. How do the pro/anti-tumorigenic effects of heparanase differ across different cancer types? Does...

Conclusion The elucidation of the function of circRNAs is an emerging field of science with a tremendous potential after previously being dismissed as RNA artifacts. They are ubiquitously expressed and thousands of members have already been identified. This fact only expands their potential to possibly enhance our knowledge to understand the difference between health and disease. Owing to their structure stability and their presence in exosomes circRNAs may also exert their function in an autocrine, paracrine and possible endocrine fashion. In addition, the fact that circRNAs are widely distributed in the cellular compart...

In conclusion, our WGCNA analysis identified candidate prognostic biomarkers for further basic and clinical researches. Introduction Breast cancer is a frequently diagnosed malignancy and the leading cause of cancer death among females around the world, accounting for 24% of cancer diagnoses and 15% of cancer deaths in females. According to Global Cancer Statistics 2018, there will be nearly 2.1 million new cases diagnosed globally, with ~62 thousand deaths. The incident rates of breast cancer increased in most developing countries during last decades, resulting from a combination of social and economic factors, incl...
