MicroRNA-495 (miR-495) is a small non-coding RNA encoded by a gene located on chromosome 14 (14q32.31). Its expression is regulated by the transcription factors EF12 and EF47, in addition to promoter methylation status and the fusion oncoprotein mixed-lineage leukemia-AF9. Previous studies suggest that miR-495 is involved in various developmental, immunological and inflammatory processes in healthy tissue, and in the proliferation, invasion, metastasis and drug resistance of cancer cells. The role miR-495 serves in tumors is controversial...

The chemokine CCL3 is a chemotactic cytokine crucial for inflammatory cell recruitment in homeostatic and pathological conditions. CCL3 might stimulate cancer progression by promoting leukocyte accumulation, angiogenesis and tumour growth. The expression of CCL3 and its receptors CCR1 and CCR5 was demonstrated in oral squamous cell carcinoma (OSCC), but their role was not defined. Here, the functions of CCL3 were assessed using a model of chemically induced tongue carcinogenesis with 4-nitroquinoline-1-oxide (4NQO)...

The photodynamic properties of Hypericin (Hyp) may be used as an alternative treatment for malignancies of the lower gastrointestinal tract and for the prevention of surgical-site infection; however, its use in photodynamic therapy has been limited because of its poor hydrosolubility. Therefore, in order to improve its water solubility and its photodynamic effect, Hyp was encapsulated in Pluronic P123 (P123) and the photodynamic effects against intestinal and epidermal bacteria and against two lineages of intestinal colon carcinoma cells were investigated...

Human mesenchymal stem cells (hMSCs) have great potential for cell-based therapies for treating degenerative bone diseases. It is known that mechanical cues in the cell microenvironment play an important role in regulating osteogenic (bone) differentiation of hMSCs. However, mechanoregulation of lineage commitment of hMSCs in conventional two-dimensional (2D) monocultures or bioengineered three-dimensional (3D) tissue constructs remains suboptimal due to complex biomaterial design criteria for hMSC culture...

Blinatumomab is a bispecific T-cell engaging αCD19 antibody used in refractory or relapsed B-cell precursor acute lymphoblastic leukemia (ALL). Recently, lineage switch to a myeloid phenotype has been described following CD19 targeting treatment in three pediatric patients with mixed lineage leukemia (MLL) rearranged ALL. We report the case of a female who received blinatumomab for a first relapse of ALL without MLL alterations. She suffered from a second relapse early after hematopoietic stem cell transplantation and was treated with blinatumomab again...

Discoba (Excavata) is an evolutionarily important group of eukaryotes that includes Jakobida, with the most bacterial-like mitochondrial genomes known, and Euglenozoa, many of which have extensively fragmented mitochondrial genomes. However, little is known about the mitochondrial genomes of Heterolobosea, the third main group of Discoba. Here, we studied two heteroloboseids - an undescribed amoeba 'BB2' and Pharyngomonas kirbyi. Phylogenomic analysis revealed that they form a clade that is a sister group to all other Heterolobosea...

The major histocompatibility complex (MHC) is a cluster of genes involved with immune responses. The chicken MHC has been shown to influence resistance to viruses, bacteria, and infections from both internal and external parasites. The highly variable chicken MHC haplotypes were initially identified by the use of haplotype-specific serological reagents. A novel SNP-based panel encompassing 210,000 bp of the MHC-B locus was developed to allow fine scale genetic analyses including rapid identification of novel haplotypes for which serological reagents are not available...

BACKGROUND: Few reliable blood markers are available for detecting gastric cancer, mainly owing to the heterogeneity of the cancer. OBJECTIVE: To establish gastric cancer diagnostic markers, we evaluated the levels of plasma cadherin 17 (CDH17) and trefoil factor 3 (TFF3), which are secretory proteins and known markers for intestinal metaplasia (IM), in patients with gastric cancer. METHOD: The protein expression level was analyzed in blood plasma samples from 111 gastric cancer patients and 44 healthy individuals, using a sandwich ELISA kit, followed by statistical analyses...

Lost or damaged cells in tissues and organs can be replaced by transplanting therapeutically competent cells. This approach requires methods that effectively manipulate cellular identities and properties to generate sufficient numbers of desired cell types for transplantation. These cells can be generated by reprogramming readily available somatic cells, such as fibroblasts, into induced pluripotent stem cells (iPSCs), which can replicate indefinitely and give rise to any somatic cell type. This reprogramming can be achieved with genetic methods, such as forced expression of pluripotency-inducing transcription factors (TFs), which can be further improved, or even avoided, with pharmacological agents...

Moxetumomab pasudotox is a second-generation recombinant immunotoxin against CD22 on B-cell lineages. Antileukemic activity has been demonstrated in children with chemotherapy-refractory B-cell precursor acute lymphoblastic leukemia (BCP-ALL), with variable responses. Here, we report in vitro and in vivo evaluation of moxetumomab pasudotox treatment of human cell lines and patient-derived cells as a preliminary study to understand characteristics of sensitivity to treatment. Binding, internalization, and apoptosis were evaluated using fluorescently tagged moxetumomab pasudotox...

Phenotypic plasticity refers to a phenomenon in which cells transiently gain traits of another lineage. During carcinoma progression, phenotypic plasticity drives invasion, dissemination and metastasis. Indeed, while most of the studies of phenotypic plasticity have been in the context of epithelial-derived carcinomas, it turns out sarcomas, which are mesenchymal in origin, also exhibit phenotypic plasticity, with a subset of sarcomas undergoing a phenomenon that resembles a mesenchymal-epithelial transition (MET)...

The human umbilical cord (UC) and placenta are non-invasive, primitive and abundant sources of mesenchymal stromal cells (MSCs) that have increasingly gained attention because they do not pose any ethical or moral concerns. Current methods to isolate MSCs from UC yield low amounts of cells with variable proliferation potentials. Since UC is an anatomically-complex organ, differences in MSC properties may be due to the differences in the anatomical regions of their isolation. In this study, we first dissected the cord/placenta samples into three discrete anatomical regions: UC, cord-placenta junction (CPJ), and fetal placenta (FP)...

Cereal grasses of the Triticeae tribe have been the major food source in temperate regions since the dawn of agriculture. Their large genomes are characterized by a high content of repetitive elements and large pericentromeric regions that are virtually devoid of meiotic recombination. Here we present a high-quality reference genome assembly for barley (Hordeum vulgare L.). We use chromosome conformation capture mapping to derive the linear order of sequences across the pericentromeric space and to investigate the spatial organization of chromatin in the nucleus at megabase resolution...

PURPOSE: Chromosomal translocation of the Mixed Lineage Leukemia (MLL) locus generates fusion proteins that drive acute myeloid leukemia (AML) resulting in atypical histone methyltransferase activity and alterations in the epigenetic regulation of gene expression. Targeting histone regulators, such as Enhancer of Zeste Homologue 2 (EZH2), has shown promise in AML. Profiling differential protein expression following inhibition of epigenetic regulators in AML may help to identify novel targets for therapeutics...

Highly complicated morphologies and sophisticated functions of vertebrate brains have been established through evolution. However, the origin and early evolutionary history of the brain remain elusive, owing to lack of information regarding the brain architecture of extant and fossil species of jawless vertebrates (agnathans). Comparative analyses of the brain of less studied cyclostomes (only extant agnathan group, consisting of lampreys and hagfish) with the well-known sister group of jawed vertebrates (gnathostomes) are the only tools we have available to illustrate the ancestral architecture of the vertebrate brain...

Elucidating the adaptive strategies and plasticity of bacterial genomes in situ is crucial for understanding the epidemiology and evolution of pathogens threatening human health. While much is known about the evolution of Escherichia coli in controlled laboratory environments, less effort has been made to elucidate the genome dynamics of E. coli in its native settings. Here, we follow the genome dynamics of co-existing E. coli lineages in situ of the infant gut during the first year of life. One E. coli lineage causes a urinary tract infection (UTI) and experiences several alterations of its genomic content during subsequent antibiotic treatment...

Fibroblasts are cells with a structural function, synthesizing components of the extracellular matrix. They are accordingly associated with various forms of connective tissue. During cardiac development fibroblasts originate from different sources. Most derive from the epicardium, some derive from the endocardium, and a small population derives from the neural crest. Cardiac fibroblasts have important functions during development, homeostasis, and disease. However, since fibroblasts are a very heterogeneous cell population no truly specific markers exist...

ANaerobic MEthanotrophic (ANME) archaea remove the greenhouse gas methane from anoxic environments and diminish its flux to the atmosphere. High methane removal efficiencies are well documented in marine environments, whereas anaerobic oxidation of methane (AOM) was only recently indicated as an important methane sink in freshwater systems. Freshwater AOM-mediating microorganisms lack taxonomic identification and only little is known about metabolic adaptions to prevailing biogeochemical conditions. One of the first study sites providing information about AOM activity in freshwater sediment is Lake Ørn, a low-sulfate, iron-rich Danish lake...
