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, Maola Khan Mohammad Golam, Michal Sabisz, Alice Baumann, Kaycie Marie Butler

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 ...

Anti-angiogenic immunotherapy for lung cancer

Ece Kadioglu

Lung cancer is the leading cause of cancer-associated deaths worldwide. Platinum-based chemotherapy is the most common therapeutic approach in advanced non-small cell lung cancer (NSCLC), particularly for tumors that carry non-druggable activating mutation ...

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 ...

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 ...

DNA repair protein Rad18 restricts LINE-1 mobility

Priscilla Turelli

Long interspersed element-1 (LINE-1, L1) is a mobile genetic element comprising about 17% of the human genome. L1 utilizes an endonuclease to insert L1 cDNA into the target genomic DNA, which induces double-strand DNA breaks in the human genome and activat ...

KAP1 facilitates reinstatement of heterochromatin after DNA replication

Didier Trono, Suk Min Jang, Priscilla Turelli, Sandra Eloise Kjeldsen, Julien Léonard Duc, Annamaria Kauzlaric, Andrea Coluccio, Julien Paul André Pontis, Benjamin Rauwel, Geneviève Almouzni

During cell division, maintenance of chromatin features from the parental genome requires their proper establishment on its newly synthetized copy. The loss of epigenetic marks within heterochromatin, typically enriched in repetitive elements, endangers ge ...
