Structural basis of SIRT7 nucleosome engagement and substrate specificity

Esther Calvino Sanles, Polina Nikolaeva Foteva, Henning Paul-Julius Stahlberg, Beat Fierz, Dongchun Ni, Babatunde Edukpe Ekundayo, Carlos Moreno Yruela

Chromatin-modifying enzymes target distinct residues within histones to finetune gene expression profiles. SIRT7 is an NAD+-dependent deacylase often deregulated in cancer, which deacetylates either H3 lysine 36 (H3K36) or H3K18 with high specificity withi ...

Electrostatic and Hydrophobic Mediation in DNA/Lipid Interactions: Toward the Design of Tailored DNA/Membrane Interfaces

Siu Ho Wong

The interplay of synthetic DNA nanostructures and lipid membranes is an exciting frontier in bioengineering, with the potential to transform synthetic biology and nanomedicine. However, the fundamental principles underlying their interactions-particularly ...

CircCDYL Association With hnRNPL Modulates CDYL Isoform Switching in Breast Cancer Cells

Isabella Tarulli

Circular RNAs (circRNAs) are covalently closed back‐splicing products involved in the regulation of different cellular processes, and their dysregulation has been frequently observed in cancer cells. CircCDYL, a circRNA derived from the back‐splicing of CD ...

Oxidative stress at telomeres triggers internal DNA loops, TRF1 dissociation, and TRF2-dependent R-loops

Leona Brandl, Joachim Lingner, Wareed Ahmed, Eftychia Kyriacou, Thomas Frédéric Lunardi, Thu Trang Nguyen

Telomeres are the nucleoprotein structures at chromosome ends. Telomeres are particularly sensitive to oxidative stress, which can induce telomere damage, shortening, and premature cellular senescence. How oxidative damage influences telomere structure has ...

Search for Nuclear Modifications of (Formula presented) Meson Production in (Formula presented)-Pb Collisions at (Formula presented)

Jan Steggemann, Konstantin Androsov, Anna Mascellani, Joanna Malgorzata Wanczyk, Paul Théodore Gabriel Pablo De Bryas Dexmiers d'Archiac

Nuclear medium effects on (Formula presented) meson production are studied using the binary-collision scaled cross section ratio between events of different charged-particle multiplicities from proton-lead collisions. Data, collected by the CMS experiment ...

Resolving bacterial cell biology: from replisome dynamics to cell wall synthesis

Chen Zhang

Bacteria are ubiquitous single cellular organisms. Compared to eukaryotic cells, bacteria have two unique characteristics: the membrane-less nucleoid and the cell wall built of peptidoglycan (PG). In most bacteria, a single circular chromosome is compacted ...

Mechanism of Chromatin Ubiquitination by PRC1 on the Single-Molecule Level

Alexandra Teslenko

Multicellular eukaryotic organisms contain identical genetic information within each cell, stored within the nucleus as chromatin fibers. The regulation of gene expression allows cell-type-specific temporal and spatial gene activation or repression despite ...

Individual transcription factors modulate both the micromovement of chromatin and its long-range structure

David Michael Suter, Natalya Katanayeva, Haitham Ahmed Shaban Ahmed, Armelle Inge Marie Eleonore Tollenaere

The control of eukaryotic gene expression is intimately connected to highly dynamic chromatin structures. Gene regulation relies on activator and repressor transcription factors (TFs) that induce local chromatin opening and closing. However, it is unclear ...

ER remodelling by ER-phagy in neurogenesis

Maurizio Molinari

The endoplasmic reticulum (ER) controls the synthesis of lipids and proteins and Ca2+ homeostasis, as well as contacting other organelles and the plasma membrane. A study now looks at a process by which this compartment is remodelled in axons during neurog ...

Photo-Cross-linked DNA Structures Greatly Improves Their Serum Nuclease Resistances and Gene Knock-In Efficiencies

Youwei Ma

The stabilization and structural integrity of DNA architectures remain significant challenges in their biomedical applications, particularly when inserting functional units into the genome using long single-stranded DNA (lssDNA). To address these challenge ...

How to build the virtual cell with artificial intelligence: Priorities and opportunities

Charlotte Cäcilie Gertrud Bunne

Cells are essential to understanding health and disease, yet traditional models fall short of modeling and simulating their function and behavior. Advances in AI and omics offer groundbreaking opportunities to create an AI virtual cell (AIVC), a multi-scal ...

DNA methylation by CcrM contributes to genome maintenance in the Agrobacterium tumefaciens plant pathogen

Giovanna Ambrosini, Nicolas Jean Philippe Guex, Christian Iseli

The cell cycle-regulated DNA methyltransferase CcrM is conserved in most Alphaproteobacteria, but its role in bacteria with complex or multicentric genomes remains unexplored. Here, we compare the methylome, the transcriptome and the phenotypes of wild-typ ...
