Abstract:
Abstract Diffuse midline (DMG) and brainstem (DIPG) high-grade gliomas (HGG) bearing H3.3K27M driver mutation are aggressive and uncurable brain tumors. We evidenced by the past HIF-2a and its transcriptional gene, EPAS1, as a marker of resistance when targeting mTor/HIF-1a pathway. To understand HIF-2α potential role in chronically active hypoxic environment in DIPG/DMG, we investigate its status in a cohort of pediatric HGGs comprising notably H3.3K27M mutant tumors and in their paired in vitro derived models. Using concomitantly the low-input chromatin immunoprecipitation sequencing method

Abstract:
e22046 Background: APC mutations are believed to constitutively activate the wnt pathway in colorectal tumors. Our goal was to comprehensively characterize Wnt signaling components in a set of APC-associated FAP tumors both at the DNA and RNA levels. Methods: Sixty adenomas from FAP cases harboring pathogenic APC mutations were included (10 adenomas and 1 normal mucosa per case). Somatic APC and KRAS alterations, β-catenin immunostaining and qRT-PCR of APC, MYC, AXIN2 and SFRP1 were analyzed. aCGH was also assessed in 26 FAP adenomas and 24 additional paired normal-adenoma-carcinoma samples.

Abstract:
Abstract Introduction: Aggressive histologic subtypes of lymphoma such as mantle cell (MCL) and activated B cell (ABC) are considered incurable and affected patients often have a short median survival despite multimodal therapy. It is well established that altered expression of oncogenes and epigenetic dysregulation of tumor suppressor and regulatory genes promote cellular transformation of normal B cells into malignant lymphoma. Hypermethylation of histone proteins (H3R8 and H4R3) by the protein arginine methyltransferase 5 (PRMT5) enzyme has been documented in multiple cancer types and has b

Abstract:
Abstract Endothelial cells are relevant to normal hematopoiesis. Vascular niches within the bone marrow allow hematopoietic stem cell proliferation and differentiation. In vivo, the contemporary administration of endothelial progenitor cells in BALB/c mice fosters the homing of transplanted hematopoietic cells (Salter et al. Blood 2009; 113:2104). In vitro, the differentiation of CD34+ progenitors is facilitated by the presence of an underlying confluent layer of endothelial colony forming cells (ECFCs Ingram et al. Blood. 2004;104: 2752), even though this effect is highly dependent from the p

Abstract:
Background: The Wnt/beta-catenin pathway is one of the pathways that is deregulated in pancreatic cancer and is reported to be associated with a poor prognosis. This indicates the need for the identification of novel agents to improve the efficacy of current therapy or have an improved efficacy. Therefore, in the present study, we explored the anticancer activity of PNU- 74654 alone or in combination with gemcitabine in 2 and 3-dimensional cell culture models of pancreatic cancer. Methods: The MTT assay was carried out to determine the viability of PC cancerous cells (PCCs), while the cytotoxi

Abstract:
Epithelial Ovarian Cancer (EOC) is the most aggressive gynecological malignancy, mainly due to the advanced stage at diagnosis and the development of drug-resistant recurrences. Epigenetic modifications, such as histone methylation/acetylation, are emerging as key regulators of tumor growth and response to therapies. To verify if they are also involved in the onset of drug re-sistance in EOC, we performed a high-throughput Epigenetic Modifiers (EMs)-based screening using four different models of EOC isogenic Platinum-Resistant (PT-Res) cells. The screening identified G9a/GLP histone methyltran
