Identification of cell surface targets for CAR-T cell therapies and antibody-drug conjugates in breast cancer.

ESMO Open 2021 Apr 7;6(3):100102. Epub 2021 Apr 7.

Department of Hematology, Hospital Clinic, August Pi I Sunyer Biomedical Research Institute (IDIBAPS), Barcelona, Spain. Electronic address:

Background: Two promising therapeutic strategies in oncology are chimeric antigen receptor-T cell (CAR-T) therapies and antibody-drug conjugates (ADCs). To be effective and safe, these immunotherapies require surface antigens to be sufficiently expressed in tumors and less or not expressed in normal tissues. To identify new targets for ADCs and CAR-T specifically targeting breast cancer (BC) molecular and pathology-based subtypes, we propose a novel in silico strategy based on multiple publicly available datasets and provide a comprehensive explanation of the workflow for a further implementation.

The in vitro effects of hepatoblastoma cells on the growth and differentiation of blasts in transient abnormal myelopoiesis associated with Down syndrome.

Leuk Res 2021 Mar 31;105:106570. Epub 2021 Mar 31.

Department of Pediatrics, National Defense Medical College, Tokorozawa, Saitama-ken, Japan.

Transient abnormal myelopoiesis (TAM) in neonates with Down syndrome, which spontaneously resolves within several weeks or months after birth, may represent a special form of leukemia developing in the fetal liver (FL). To explore the role of hepatoblasts, one of the major constituents of the FL hematopoietic microenvironment, in the pathogenesis of TAM, we investigated the influence of a human hepatoblastoma cell line, HUH-6, on the in vitro growth and differentiation of TAM blasts. In a coculture system with membrane filters, which hinders cell-to-cell contact between TAM blasts and HUH-6 cells, the growth and megakaryocytic differentiation of TAM blast progenitors were increased in the presence of HUH-6 cells.

Internalizing and externalizing problems across childhood and psychotic-like experiences in young-adulthood: The role of developmental period.

Schizophr Res 2021 Apr 7;231:108-114. Epub 2021 Apr 7.

Department of Psychology and Human Development, University College London, London WC1H 0AA, United Kingdom.

Background: Psychopathology in childhood and adolescence, commonly indexed by co-occurring internalizing and externalizing problem behaviors, has been found to predict psychotic-like experiences (PLEs) in adults. However, studies to date have rarely examined internalizing and externalizing problem behaviors simultaneously or identified in which developmental period do these problem behaviors predict PLEs in adults. This study tests to what extent internalizing and externalizing problem behaviors in childhood (4-9 years) or adolescence (11-16 years) predict PLEs in young-adulthood (18 years). Read More

Redox Biol 2020 Dec 18;41:101834. Epub 2020 Dec 18.

National University Cancer Institute, National University Health System, Singapore; Department of Physiology, Yong Loo Lin School of Medicine, NUS, Singapore; Integrative Science and Engineering Programme, NUS Graduate School, NUS, Singapore; Faculté de Medicine, University of Paris, Paris, France. Electronic address:

Apart from its physiological role in inflammation and immunity, the nuclear factor-kappa B (NF-κB) protein complex has been implicated in tumorigenesis and its progression. Here, we provide evidence that a pro-oxidant milieu is an upstream effector of oncogenic NF-κB signaling. Through pharmacological or genetic inhibition of SOD1, we show that elevated intracellular superoxide (O) mediates sustained IKK phosphorylation, and induces downstream degradation of IκBα, leading to the nuclear localization and transcriptional activation of NF-κB.

Department of Chemistry and Biochemistry, Université de Moncton, Moncton, NB, Canada; New Brunswick Center for Precision Medicine, Moncton, NB, Canada. Electronic address:

Neutrophils play a key role in the innate immunity with their ability to generate and release inflammatory mediators that promote the inflammatory response and consequently restore the hemostasis. As active participants in several steps of the normal inflammatory response, neutrophils are also involved in chronic inflammatory diseases such as asthma, atherosclerosis, and arthritis. Given their dual role in the modulation of inflammation, regulating the inflammatory response of neutrophils has been suggested as an important therapeutic approach by numerous researchers.

Institut de Ciència i Tecnologia Ambientals, Universitat Autònoma de Barcelona, Bellaterra, Spain; Institució Catalana de Recerca i Estudis Avançats, Barcelona, Spain.

The absence of sound sampling procedures and statistical analyses to estimate solid waste generation in many developing countries has resulted in incomplete historical records of waste quantity and composition. Data is often arbitrarily aggregated or disaggregated as a function of waste generators to obtain results at the desired spatial level of analysis. Inference fallacies arising from the generalization or individualization of results are almost never considered. Read More
