Sirt6 deletion in bone marrow-derived cells increases atherosclerosis - Central role of macrophage scavenger receptor 1

Johan Auwerx, Matthias Alexander Sokrates Stein, Julien Weber, Tasneem Arsiwala

Aims: Sirtuin 6 (Sirt6) is a NAD(+)-dependent deacetylase that plays a key role in DNA repair, inflammation and lipid regulation. Sirt6-null mice show severe metabolic defects and accelerated aging. Macrophage-foam cell formation via scavenger receptors is ...

Mechanoresponsive Micro- and Nanoparticles

Harm-Anton Klok, Friederike Katharina Metze

Mechanical stimuli are ubiquitous in the human body. In contrast to biochemical stimuli such as pH, redox, hypoxia or enzymes as well as exogenous stimuli such as magnetic fields, temperature or ultrasound, endogenous biomechanical stimuli have only receiv ...

Vertical Ionization Energies and Electron Affinities of Native and Damaged DNA Bases, Nucleotides, and Pairs from Density Functional Theory Calculations: Model Assessment and Implications for DNA Damage Recognition and Repair

Ursula Röthlisberger, Ivano Tavernelli, Polydefkis Diamantis

To assess the effect of an 8-oxoguanine (8OG) defect base on the vertical ionization energies (VIEs) and electron affinities (VEAs) of DNA, density functional theory calculations were carried out for native and defect DNA bases and nucleotides, as well as ...

Detecting topological variations of DNA at single-molecule level

Aleksandra Radenovic, Georg Fantner, Adrian Pascal Nievergelt, Ke Liu

In addition to their use in DNA sequencing, ultrathin nanopore membranes have potential applications in detecting topological variations in deoxyribonucleic acid (DNA). This is due to the fact that when topologically edited DNA molecules, driven by electro ...

Niacin: an old lipid drug in a new NAD(+) dress

Johan Auwerx, Mario Romani, Elena Katsyuba, Dina Hofer

Niacin, the first antidyslipidemic drug, has been at the center stage of lipid research for many decades before the discovery of statins. However, to date, despite its remarkable effects on lipid profiles, the clinical outcomes of niacin treatment on cardi ...

RADX: A novel single-stranded DNA-binding protein regulating telomere recombination

Anna-Sophia Briod

Telomeres are specialized nucleoprotein structures present at the ends of linear chromosome. The telomeric DNA part is comprised of 5-15 kilo base pairs of double stranded TTAGGG repeats and it contains at the 3' end a single-stranded G-rich overhang of 50 ...

Engineered peptide macrocycles can inhibit matrix metalloproteinases with high selectivity

Christian Heinis, Xudong Kong, Jonas Alfred Karl Wilbs, Jeremy Touati, Michal Sabisz, Alice Baumann

Matrix metalloproteinases (MMPs) are zinc‐dependent endopeptidases at the intersection of health and disease due to their involvement in processes such as tissue repair and immunity as well as cancer and inflammation. Because of the high structural conserv ...

Functional analysis of the telomeric long non-coding RNA TERRA

Patricia Renck Nunes

Telomeres are nucleoprotein structures present in the end of linear chromosomes. In humans, a core complex of 6 proteins cap and protect the chromosome ends from being recognized as double-strand breaks and eliciting unwanted DNA damage and repair response ...

Reuse s to xl, A network of hubs for research and resale of second hand architectural components and materials, as an active strategy for sustainability and circular economy

Célia Marine Küpfer

Distinct from recycling, reuse maintains the shape, energy, know-how, technology and cultural part embedded in a component to use it beyond an initial use into a new project without strongly altering it. The "hub" for research and resale of reusable constr ...

Pan-Cancer Landscape of Aberrant DNA Methylation across Human Tumors

Douglas Hanahan, Mohammad Sadegh Saghafinia, Giovanni Ciriello, Marco Mina

The discovery of cancer-associated alterations has primarily focused on genetic variants. Nonetheless, altered epigenomes contribute to deregulate transcription and promote oncogenic pathways. Here, we designed an algorithmic approach (RESET) to identify a ...
