Conclusions: Tumor pattern differs in neonates and infants, with a higher percentage of benign tumors in children below 28 days of life. Yet, long-term therapy-related toxicity is significant in younger patients. Enhancing knowledge of neonatal tumors, their epidemiology, clinical presentation, genetic background, and prognosis should help promote better management and introduce follow-up programs to improve surviving rates and the quality of life of survivors.

Authors: Stachowicz-Stencel T, Synakiewicz A Abstract Cancer is one of the major health problems of the modern world. With the development of novel biochemistry and analytical instrumentation, precancer diagnosis has become a major focus of clinical and preclinical research. Finding appropriate biomarkers is crucial to make an early diagnosis, before the disease fully develops. With the improvement of precancer studies, cancer biomarkers prove their usefulness in providing important data on the cancer type and the status of patients' progression at a very early stage of the disease. Due to the constant evolution of...

Kruyt F, Dolga AM Abstract Brain tumours are among the deadliest tumours being highly resistant to currently available therapies. The proliferative behaviour of gliomas is strongly influenced by ion channel activity. Small-conductance calcium-activated potassium (SK/KCa) channels are a family of ion channels that are associated with cell proliferation and cell survival. A combined treatment of classical anti-cancer agents and pharmacological SK channel modulators has not been addressed yet. We used the gold-derivative auranofin to induce cancer cell death by targeting thioredoxin reductases in combination with CyP...

Conclusions1. Glioblastoma, anaplastic glioma and neuroblastoma cell lines have a high sensitivity to Cabazitaxel in vitro. 2. Cell lines with MGMT methylation and MMR expression (A172 and LN 229) are the most sensitive. Of them, line A172 presents a p53 wild type, and therefore, a greater sensitivity to Cabazitaxel. 3. The expression of CD133 correlates inversely with the values of IC50 to Cabazitaxel, and may also be a predictor of response.Legal entity responsible for the studyUGR.FundingHas not received any funding.DisclosureAll authors have declared no conflicts of interest.

dola Lupo Satriano Angiogenin (ANG), an endogenous protein that plays a key role in cell growth and survival, has been scrutinised here as promising nanomedicine tool for the modulation of pro-/anti-angiogenic processes in brain cancer therapy. Specifically, peptide fragments from the putative cell membrane binding domain (residues 60–68) of the protein were used in this study to obtain peptide-functionalised spherical gold nanoparticles (AuNPs) of about 10 nm and 30 nm in optical and hydrodynamic size, respectively. Different hybrid biointerfaces were fabricated by peptide physical adsorption (Ang60&am...

AbstractThe N-Myc downstream-regulated gene (NDRG) family consists of four members (NDRG1,NDRG2,NDRG3,NDRG4) that are differentially expressed in various organs and function in important processes, like cell proliferation and differentiation. In the last couple of decades, interest in this family has risen due to its connection with several disorders of the nervous system including Charcot-Marie-Tooth disease and dementia, as well as nervous system cancers. By combining a literature review with in silico data analysis of publicly available datasets, such as the Mouse Brain Atlas, BrainSpan, the Genotype-Tissue Expression (...

157Objectives: Neuroblastoma is the most common extracranial tumors in children, and about half of patients have metastatic disease at presentation (1, 2). I-123-MIBG has been recognized as a radiopharmaceutical of choice in neuroblastoma assessment (3, 4). In recent years, promising diagnostic results are reported by F-18-FDOPA PET-CT after 60-90 min of radiopharmaceutical injection (delay F-18-FDOPA PET-CT) (5, 6). Early F-18-FDOPA PET-CT (3-30 min scan after radiopharmaceutical injection) showed better diagnostic performance in medullary thyroid cancer and brain tumor (7, 8), however, it has not been studied in neurobla...

Conclusion Astroblastoma is an extremely rare CNS tumor. Morphological diagnosis is difficult, as the typical astroblastic rosettes may be present also in other CNS tumors, including some gliomas and ependymomas. In fact, AB can be considered as a morphologic pattern, which can be associated with a spectrum of molecular entities. Total resection is the best treatment; the precise role of chemotherapy and radiotherapy is still debated, particularly for high-grade tumors. We believe that DNA-methylation profiles represents an important instrument for confirming diagnosis, predicting prognosis and better defining the molec...

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...

Markus Hartl* and Rainer Schneider Center of Molecular Biosciences (CMBI), Institute of Biochemistry, University of Innsbruck, Innsbruck, Austria The neuronal proteins GAP43 (neuromodulin), MARCKS, and BASP1 are highly expressed in the growth cones of nerve cells where they are involved in signal transmission and cytoskeleton organization. Although their primary structures are unrelated, these signaling proteins share several structural properties like fatty acid modification, and the presence of cationic effector domains. GAP43, MARCKS, and BASP1 bind to cell membrane phospholipids, a process reversibly regulate...
