TOP STORYThe authors showed that chronic myelogenous leukemia stem cells demonstrated increased expression of the IL-1 receptors, IL-1RAP and IL-1R1, and enhanced sensitivity to IL-1-induced NF-κB signaling compared to normal stem cells. [Blood] Abstract |

PUBLICATIONS(Ranked by impact factor of the journal)Researchers showed that primitive chronic myeloid leukemia (CML) cells, in contrast to corresponding normal cells, express a functional IL1 receptor complex and respond with NFKB activation and marked proliferation in response to IL1. IL1RAP antibodies that inhibit IL1 signaling could block these effects. [Blood] Abstract Gastric carcinomas (GC) are heterogeneous, and the current therapy remains essentially based on surgery with conventional chemo- and radiotherapy. This study aimed to characterize biomarkers allowing the detection of cancer stem cells in human GC of different histological types. [Clin Cancer Res] Abstract Lineage-Restricted OLIG2-RTK Signaling Governs the Molecular Subtype of Glioma Stem-like Cells Investigators showed that OLIG2 modulates growth factor signaling in two distinct populations of glioma stem-like cells, characterized by expression of either the epidermal growth factor receptor or platelet-derived growth factor receptor alpha. [Cell Rep] Full Article | Graphical Abstract Unravelling the Relevance of CLEC12A as a Cancer Stem Cell Marker in Myelodysplastic Syndrome Investigators showed that the CD34+ CD38– C-type lectin domain family 12, member A (CLEC12A+) cells were indeed malignant and possessed functional stem cell properties in the long-term colony-initiating cell assay. As opposed to reported findings in acute myeloid leukemia, they showed that cancer stem cells from myelodysplastic syndrome samples derived from both CLEC12A positive and negative CD34+ CD38– subpopulations. [Br J Haematol] Full Article Researchers employed a mouse model of acute myeloid leukemia (AML) expressing the fusion oncogene MLL-AF9 and explore the effects of Atg5 deletion, a key autophagy protein, on the malignant transformation and progression of AML. Consistent with a transient decrease in colony-forming potential in vitro, the in vivo deletion of Atg5 in MLL-AF9-transduced bone marrow cells during primary transplantation prolonged the survival of recipient mice, suggesting that autophagy has a role in MLL-AF9-driven leukemia initiation. [Cell Death Dis] Full Article In order to enhance the biological activity of α-mangostin, researchers formulated mangostin-encapsulated PLGA nanoparticles and examined the molecular mechanisms by which they inhibit human and PdxCre;LSL-KrasG12D mice pancreatic cancer stem cell characteristics in vitro, and pancreatic carcinogenesis in PdxCre;LSLKrasG12D;LSL-Trp53R172H mice. [Sci Rep] Full Article Ultrasonic Surgical Aspirate is a Reliable Source for Culturing Glioblastoma Stem Cells Scientists showed that ultrasonic aspirate (UA) samples offer a large and reliable source of live cells. Similar to core biopsies, UA samples enriched for glioma stem cells (GSCs) that differentiated into neural lineages, showed inter-individual variation of GSC markers, and induced tumors. [Sci Rep] Full Article The human choriocarcinoma cell line JEG-3 was cultured in serum free media, and the characteristics of suspension and parental adherent JEG-3 cells were compared. [Cell Physiol Biochem] Full Article Aldehyde Dehydrogenases Inhibition Eradicates Leukemia Stem Cells while Sparing Normal Progenitors To try to combat the leukemia stem cell population selectively, a well-characterized ALDH inhibitor by the trivial name of dimethyl ampal thiolester was assessed on sorted CD34+CD38− subpopulations from AML patients and healthy patients. ALDH activity and cell viability were monitored by flow cytometry. [Blood Cancer J] Full Article |

REVIEWSA significant effort has been made to identify agents that specifically target multidrug resistance (MDR) cells and cancer stem cells (CSCs). Consequently, some agents derived from nature have been developed with a view that they may overcome MDR and/or target CSCs. In this review, natural products-targeting MDR cancer cells and CSCs are summarized and clustered by their targets in different signaling pathways.

INDUSTRY NEWSSELLAS Life Sciences Group announced that it has entered into a Cooperative Research and Development Agreement (CRADA) with the US National Heart, Lung and Blood Institute, National Institutes of Health. The research plan of the CRADA is designed to develop a novel AML MRD assay for monitoring the expression of multiple genes that can document the kinetics of minimal residual disease (MRD) in acute myeloid leukemia during treatment with SELLAS’ most advanced product candidate, galinpepimut-S, the company’s WT1 cancer vaccine. [SELLAS Life Sciences Group (PR Newswire Association LLC.)] Press Release Regen BioPharma, Inc. Responds to FDA on dCellVax Gene-Silenced Breast Cancer Immunotherapy Regen BioPharma, Inc. announced submission to the Food and Drug Administration (FDA) of a revised Investigational New Drug application focused on using a novel method to unleash the body’s innate ability to kill cancer. The package submitted contained preclinical experiments as well as details of the proposed clinical trial. [Regen BioPharma, Inc. (PR Newswire Association LLC.)] Press Release Array BioPharma Announces Phase III BEACON CRC SPA Agreement with FDA Array BioPharma announced that it has reached agreement with the U.S. Food and Drug Administration (FDA) regarding a Special Protocol Assessment related to BEACON CRC, a global Phase III trial of encorafenib and Erbitux®, with or without binimetinib, versus standard of care in patients with BRAF-mutant colorectal cancer (CRC) who have previously received first-or second-line systemic therapy.
