50. Loss of TP53 in a pediatric patient with Down syndrome, B-lymphoblastic leukemia, and the t(8;14)(q11.2q32) CEBPD/IGH translocation

B-acute lymphoblastic leukemia (B-ALL) in patients with Down syndrome (DS) has a worse prognosis than non-DS B-ALL. However, associated cytogenetic alterations may alter the prognosis. Here we discuss a 13-year-old female with DS presenting with leg pain, fevers, white blood cell count 12.8 k/ul, hemoglobin 7.7 g/dL, platelets 31 k/ul, and 60.9% blasts on differential. Flow cytometry identified B-lymphoblasts (positive for CD19, cytoCD79a, cytoCD22, CD34, CD10, TdT, and CD45 (dim)) and bone marrow biopsy demonstrated sheets of B-lymphoblasts.

Publication date: Available online 18 January 2020Source: Redox BiologyAuthor(s): Mohamad Assi, Suzanne Dufresne, Amélie RébillardAbstractIn this paper of the special issue dedicated for the Olympics 2020, we put the light on an exciting facet of exercise-oncology, which may still be unknown to some audience. Accumulating convincing evidences show that exercise reduces cancer progression and recurrence mainly in colon and breast cancer patients. Interestingly, the positive effects of exercise on cancer outcomes were mainly observed when patients practiced vigorous exercise of 6 METs or more. At the molecular ...

Authors: Bharadwaj AS, Swamy PM, Mamas MA Abstract Introduction: There are numerous shared risk factors in the etiopathogenesis of coronary artery disease (CAD) and cancer both at the epidemiologic and molecular level. Additionally, the different modalities of treatment of cancer such as radiation, chemotherapy, immunotherapy and hormonal therapies further increase the risk of CAD and acute coronary syndrome. Most large database analysis and single center experiences have shown that cancer patients undergoing PCI are at an increased risk of in-hospital mortality, bleeding repeat revascularization.Areas covered: In ...

Authors: Annibale B, Esposito G, Lahner E Abstract SUMMARYIntroduction: Atrophic gastritis (AG) is a complex syndrome which arise as consequence of H. pylori infection or in the context of gastric autoimmunity. It often deserves a benign course, but may lead to potentially life-threatening complications: cancer and anaemia. This review aims to address traditional and innovative knowledge on this often under-diagnosed disorder.Areas covered: This review covers clinical presentation, risk factors, diagnosis and management of AG and provides an updated resource for clinicians to get insight in this challenging disorde...

This article seeks to shed light on the dualistic role of Wnt signalling in liver regeneration following injury and how Wnt signalling can regulate scar formation. It also discusses how Wnt signalling cooperates with other classical fibrogenic signalling cascades, such as TGFβ signalling. Finally, the article examines recent advances in the development of Wnt signalling pathway inhibitors and asks whether repurposing these agents as anti-fibrotic therapies is a realistic option.Expert Opinion: The understanding of Wnt signalling in liver regeneration and fibrosis is in its infancy and whilst new generations of Wnt pat...

Abstract Protein N-glycosylation plays crucial roles in many biological processes and has close association with the occurrence and development of various cancers. Therefore, it is necessary to analyze the abnormal changes of N-glycopeptides in complex biological samples for biomarker discovery. However, due to their low abundance and poor ionization, N-glycopeptides identification in complex samples by mass spectrometry (MS) is still a challenging task. In this work, a novel magnetic hydrophilic material was prepared by serial functionalization of ultra-thin two-dimensional molybdenum disulfide with Fe3O4 nanopar...

Abstract Telomerase activity is inhibited in normal somatic cells but abnormally high in the majority of cancer cells. Maintenance of active telomerase in cancer cells promotes proliferation and immortalization. With the difference in telomerase activity between cancer and normal cells in mind, we designed a nanoprobe based on quantum dot (QD) and fluorescence resonance energy transfer (FRET). The nanoprobe consisted of a specific sequence of DNA with the two ends labeled with QD as a fluorescent donor and Alexa488 as a fluorescent acceptor, respectively. FRET signal tracking was performed by adjusting the distanc...

Abstract A near-infrared (NIR) photothermal immunoassay was designed for the sensitive monitoring of CA 19-9 on the capture antibody-coated microplate, coupling a 3D-printed device with a digital thermometer in this work. Prussian blue nanoparticles (PBNPs)-encapsulated CaCO3 microspheres were not only utilized for labeling of detection antibody, but used as the photo-heat conversion materials for the signal amplification. With the sandwiched immunocomplex, the as-released PBNPs under acidic conditions adsorbed and converted NIR-light wavelength to heat under 808-nm laser irradiation, thereby resulting in the temp...

Abstract RNA molecules carry diverse modifications that exert important influences in many cellular processes. In addition to the single modification occurring in either nucleobase or 2' hydroxyl of ribose in RNA, some dual modifications occur in both the nucleobase and 2' hydroxyl of ribose in RNA. 2'-O-methyl-5-methylcytidine (m5Cm), the dual modifications of cytidine, was first discovered from the tRNA of archaea. Recent studies identified that 2'-O-methyl-5-hydroxymethylcytidine (hm5Cm) and 2'-O-methyl-5-formylcytidine (f5Cm) were present in the anticodon of cytoplasmic tRNA of mammals. Similar to the series o...
