Lactoferrin (LF) is a soluble glycoprotein of the transferring family found in most biological fluids, functioning as a major first line defense molecule against infection in mammals. It also shows certain anti-tumor activity, but its clinical application in tumor therapy is limited because high dosage is required. In this study, we demonstrate that M860, a monoclonal antibody against human LF (hLF), could significantly increase the anti-tumor potential of low dosage hLF by forming LF-containing immune complex (IC).

Carcinogenesis is a multistep process, and tumors frequently harbor multiple mutations regulating genome integrity, cell division and death. The integrity of cellular genome is closely controlled by the mechanisms of DNA damage signaling and DNA repair. The association of breast cancer susceptibility genes and with breast and ovarian cancer development was first demonstrated over 20 years ago.

Collective Motion as an Ultimate Effect in Crowded Selfish Herds.

Sci Rep

April 2019

Artificial Life Lab of the Institute of Biology, Karl-Franzens University of Graz, A-8010, Graz, Austria.

The selfish herd hypothesis explains how social prey can assemble cohesive groups for maximising individual fitness. However, previous models often abstracted away the physical manifestation of the focal animals such that the influence of getting stuck in a crowded herd on individual adaptation was less intensively investigated. Here, we propose an evolutionary model to simulate the adaptation of egoistic social prey to predation given that individual mobility is strictly restrained by the presence of other conspecifics.

BRCA1 and EZH2 cooperate in regulation of prostate cancer stem cell phenotype.

Prostate cancer (PCa) is the second most common malignancy and the sixth leading cause of cancer-related death among men worldwide. Prostate carcinogenesis is driven by the accumulation of genetic and epigenetic aberrations, which regulate cancer cell transition between a stem- and nonstem-cell state and accelerate tumor evolution. Elevated expression of enhancer of zeste homolog 2 (EZH2) histone methyltransferase, a core member of the polycomb repressive complex 2 (PRC2), results in cancer progression through histone methylation-driven tumor cells dedifferentiation.

Artificial Life Laboratory of the Institute of Biology, Karl-Franzens University Graz, Universitätsplatz 2, 8010 Graz, Austria.

Self-organized collective behavior has been analyzed in diverse types of gregarious animals. Such collective intelligence emerges from the synergy between individuals, which behave at their own time and spatial scales and without global rules. Recently, robots have been developed to collaborate with animal groups in the pursuit of better understanding their decision-making processes.

It has been suggested that geomagnetic storms could be perceived by organisms via disruption of naturally occurring diurnal geomagnetic variation. This variation, in turn, is viewed by way of a zeitgeber for biological circadian rhythms. The biological effects of a geomagnetic storm, therefore, could depend on the local time of day when its main phase occurs.

Malignant tumors are characterized by structural and molecular peculiarities providing a possibility to directionally deliver antitumor drugs with minimal impact on healthy tissues and reduced side effects. Newly formed blood vessels in malignant lesions exhibit chaotic growth, disordered structure, irregular shape and diameter, protrusions, and blind ends, resulting in immature vasculature; the newly formed lymphatic vessels also have aberrant structure. Structural features of the tumor vasculature determine relatively easy penetration of large molecules as well as nanometer-sized particles through a blood⁻tissue barrier and their accumulation in a tumor tissue.

We report combined therapy using upconversion nanoparticles (UCNP) coupled to two therapeutic agents: beta-emitting radionuclide yttrium-90 (Y) fractionally substituting yttrium in UCNP, and a fragment of the exotoxin A derived from genetically fused with a targeting designed ankyrin repeat protein (DARPin) specific to HER2 receptors. The resultant hybrid complex UCNP-R-T was tested using human breast adenocarcinoma cells SK-BR-3 overexpressing HER2 receptors and immunodeficient mice, bearing HER2-positive xenograft tumors. The photophysical properties of UCNPs enabled background-free imaging of the UCNP-R-T distribution in cells and animals.

Dr. Sonja Jähnig is a group leader, Vanessa Bremerich a technician, Dr. Jörg Freyhof a project leader, Dr. Simone D. Langhans a postdoctoral researcher, and Fengzhi He a doctoral student at the Leibniz-Institute of Freshwater Ecology and Inland Fisheries, in Berlin, Germany; FH is also affiliated with the Institute of Biology at Freie Universität Berlin. Dr. Savrina F. Carrizo was a program officer with the International Union for Conservation of Nature (IUCN) Global Species Programme's Freshwater Biodiversity Unit at the time of this research. Dr. Ian Harrison is working for the IUCN Freshwater Fish Specialist Group, in Flagstaff, Arizona. Professor Klement Tockner currently serves as the president of the Austrian Science Fund, in Vienna. Dr. Christiane Zarfl is a junior professor at the Center for Applied Geosciences at Eberhard Karls Universität Tübingen, in Germany. Dr. William Darwall is the head of the IUCN Global Species Programme's Freshwater Biodiversity Unit, in Cambridge, United Kingdom.

Freshwater biodiversity is highly threatened and is decreasing more rapidly than its terrestrial or marine counterparts; however, freshwaters receive less attention and conservation investment than other ecosystems do. The diverse group of freshwater megafauna, including iconic species such as sturgeons, river dolphins, and turtles, could, if promoted, provide a valuable tool to raise awareness and funding for conservation. We found that freshwater megafauna inhabit every continent except Antarctica, with South America, Central Africa, and South and Southeast Asia being particularly species rich.

Twin-arginine translocation (Tat) systems transport folded proteins across cellular membranes with the concerted action of mostly three membrane proteins: TatA, TatB, and TatC. Hetero-oligomers of TatB and TatC form circular substrate-receptor complexes with a central binding cavity for twin-arginine-containing signal peptides. After binding of the substrate, energy from an electro-chemical proton gradient is transduced into the recruitment of TatA oligomers and into the actual translocation event.

National ecosystem assessments form an essential knowledge base for safeguarding biodiversity and ecosystem services. We analyze eight European (sub-)national ecosystem assessments (Portugal, United Kingdom, Spain, Norway, Flanders, Netherlands, Finland, and Germany) and compare their objectives, political context, methods, and operationalization. We observed remarkable differences in breadth of the assessment, methods employed, variety of services considered, policy mandates, and funding mechanisms.

Downregulation of Gene Ameliorates Metabolic and Cardiac Traits in the Spontaneously Hypertensive Rat.

Hypertension

The spontaneously hypertensive rat (SHR), one of the most widely used model of essential hypertension, is predisposed to left ventricular hypertrophy, myocardial fibrosis, and metabolic disturbances. Recently, quantitative trait loci influencing blood pressure, left ventricular mass, and heart interstitial fibrosis were genetically isolated within a minimal congenic subline that contains only 7 genes, including mutant (promyelocytic leukemia zinc finger) candidate gene. To identify as a quantitative trait gene, we targeted in the SHR using the transcription activator-like effector nuclease technique and obtained SHR line harboring targeted gene with a premature stop codon.
