Stem Cell Factor Is Selectively Secreted by Arterial Endothelial Cells in Bone Marrow
ARTICLE DOI: 10.1038/s41467-018-04726-3 OPEN Stem cell factor is selectively secreted by arterial endothelial cells in bone marrow Chunliang Xu1,2, Xin Gao1,2, Qiaozhi Wei1,2, Fumio Nakahara 1,2, Samuel E. Zimmerman3,4, Jessica Mar3,4 & Paul S. Frenette 1,2,5 Endothelial cells (ECs) contribute to haematopoietic stem cell (HSC) maintenance in bone marrow, but the differential contributions of EC subtypes remain unknown, owing to the lack 1234567890():,; of methods to separate with high purity arterial endothelial cells (AECs) from sinusoidal endothelial cells (SECs). Here we show that the combination of podoplanin (PDPN) and Sca-1 expression distinguishes AECs (CD45− Ter119− Sca-1bright PDPN−) from SECs (CD45− Ter119− Sca-1dim PDPN+). PDPN can be substituted for antibodies against the adhesion molecules ICAM1 or E-selectin. Unexpectedly, prospective isolation reveals that AECs secrete nearly all detectable EC-derived stem cell factors (SCF). Genetic deletion of Scf in AECs, but not SECs, significantly reduced functional HSCs. Lineage-tracing analyses suggest that AECs and SECs self-regenerate independently after severe genotoxic insults, indicating the per- sistence of, and recovery from, radio-resistant pre-specified EC precursors. AEC-derived SCF also promotes HSC recovery after myeloablation. These results thus uncover heterogeneity in the contribution of ECs in stem cell niches. 1 The Ruth L. and David S.

Effect of Processing on Phenolic Composition of Olive Oil Products and Olive Mill By-Products and Possibilities for Enhancement of Sustainable Processes
processes Review Effect of Processing on Phenolic Composition of Olive Oil Products and Olive Mill By-Products and Possibilities for Enhancement of Sustainable Processes Fereshteh Safarzadeh Markhali CEB—Centre of Biological Engineering, Campus of Gualtar, University of Minho, 4710-057 Braga, Portugal; [email protected] or [email protected] Abstract: The bio-functional properties of olive oil products and by-products rely greatly on the proportions and types of the endogenous phenolics that may favorably/unfavorably change during various processing conditions. The olive oil industrial activities typically produce (i) olive oils, the main/marketable products, and (ii) olive mill by-products. The mechanical processing of olive oil extraction is making progress in some areas. However, the challenges inherent in the existing system, taking into consideration, the susceptibilities of phenolics and their biosynthetic variations during processing, hamper efforts to ascertain an ideal approach. The proposed innovative means, such as inclusion of emerging technologies in extraction system, show potential for sustainable development of olive oil processing. Another crucial factor, together with the technological advancements of olive oil extraction, is the valorization of olive mill by-products that are presently underused while having great potential for extended/high-value applications. A sustainable re-utilization of these Citation: Safarzadeh Markhali, F. valuable by-products helps contribute to (i) food and nutrition security and (ii) economic and Effect of Processing on Phenolic Composition of Olive Oil Products environmental sustainability. This review discusses typical processing factors responsible for the and Olive Mill By-Products and fate of endogenous phenolics in olive oil products/by-products and provides an overview of the Possibilities for Enhancement of possibilities for the sustainable processing to (i) produce phenolic-rich olive oil and (ii) optimally Sustainable Processes. -

Although a potential anticancer activity has been reported, only limited evidence has been provided in cutaneous malignant melanoma. The present study is aimed at investigating the selective in vitro anti-proliferative activity of oleocanthal against human malignant melanoma cells. Since oleocanthal is not commercial available, it was obtained as pure standard by direct extraction and purification from extra virgin olive oil. Cell viability experiments carried out by WST-1 assay demonstrated that oleocanthal had a remarkable and selective activity for human melanoma cells versus normal dermal fibroblasts with IC50s in the low micromolar range of concentrations. Such an effect was paralleled by a significant inhibition of ERK1/2 and AKT phosphorylation and down-regulation of Bcl-2 expression. These findings may suggest that extra virgin olive oil phenolic extract enriched in oleocanthal deserves further investigation in skin cancer. -

ARTICLE Received 20 Feb 2015 | Accepted 17 Apr 2015 | Published 26 May 2015 DOI: 10.1038/ncomms8214 OPEN Comprehensive survey of condition-specific reproductive isolation reveals genetic incompatibility in yeast Jing Hou1, Anne Friedrich1, Jean-Sebastien Gounot1 & Joseph Schacherer1 Genetic variation within a species could cause negative epistasis leading to reduced hybrid fitness and post-zygotic reproductive isolation. Recent studies in yeasts revealed chromo- somal rearrangements as a major mechanism dampening intraspecific hybrid fertility on rich media. Here, by analysing a large number of Saccharomyces cerevisiae crosses on different culture conditions, we show environment-specific genetic incompatibility segregates readily within yeast and contributes to reproductive isolation. Over 24% (117 out of 481) of cases tested show potential epistasis, among which 6.7% (32 out of 481) are severe, with at least 20% of progeny loss on tested conditions. Based on the segregation patterns, we further characterize a two-locus Dobzhansky–Mu¨ller incompatibility case leading to offspring respiratory deficiency caused by nonsense mutation in a nuclear-encoding mitochondrial gene and tRNA suppressor. We provide evidence that this precise configuration could be adaptive in fluctuating environments, highlighting the role of ecological selection in the onset of genetic incompatibility and reproductive isolation in yeast. 1 Department of Genetics, Genomics and Microbiology, University of Strasbourg/CNRS, UMR7156, 28 rue Goethe, 67083 Strasbourg, France.

Read Full License Page 1/33 Abstract Background Breast cancer is one of the most important causes of mortality in the world, and Tamoxifen therapy is known as a medication strategy for estrogen receptor-positive breast cancer. In current study, two hypotheses of Tamoxifen consumption in breast cancer cell line (MCF7) were investigated. First, the effect of Tamoxifen on genes expression prole at transcriptome level was evaluated between the control and treated samples. Second, due to the fact that Tamoxifen is known as a mutagenic factor, there may be an association between the alterations of genetic variants and Tamoxifen treatment, which can impact on the drug response. Methods In current study, the whole-transcriptome (RNA-seq) dataset of four investigations (19 samples) were derived from European Bioinformatics Institute (EBI). At transcriptome level, the effect of Tamoxifen was investigated on gene expression prole between control and treatment samples. -

Patel, PhD University of Pittsburgh, 2019 Abstract Acute myelogenous leukemia (AML) is a disease characterized by undifferentiated bone-marrow progenitor cells dominating the bone marrow. Currently the five-year survival rate for AML patients is 27.4 percent. Meanwhile the standard of care for most AML patients has not changed for nearly 50 years. We now know that AML is a genetically heterogeneous disease and therefore it is unlikely that all AML patients will respond to therapy the same way. Upregulation of protein-tyrosine kinase signaling pathways is one common feature of some AML tumors, offering opportunities for targeted therapy. -
