Control of nuclear envelope dynamics during acute ER stress by LINC complexes disassembly and selective, asymmetric autophagy of the outer nuclear membrane

Maurizio Molinari

The endoplasmic reticulum (ER) extends to the outer (ONM) and the inner (INM) nuclear membrane forming the nuclear envelope (NE) that delimits the nucleoplasm containing the cell genome. Unfolded protein responses (UPRs) and reticulophagy responses increas ...

Dynamics of CLIMP-63 S-acylation control ER morphology

Vassily Hatzimanikatis, Françoise Gisou van der Goot Grunberg, Graham Knott, Kathryn Hess Bellwald, Luciano Andres Abriata, Laurence Gouzi Abrami, Patrick Alain Sandoz, Catherine Maclachlan, Béatrice Kunz, Sylvia Ho, Gard Spreemann, Robin Alexander Denhardt-Eriksson

A key player in the formation of endoplasmic reticulum sheets is CLIMP-63, but mechanistic details remained elusive. Here authors combined cellular experiments and mathematical modelling to show that S-acylation of CLIMP-63 regulates its function by mediat ...

Pde-Constrained Optimization For Nuclear Mechanics

Aleix Boquet I Pujadas

We propose an image based PDE-constrained optimisation framework to compute the dynamical quantities of a cell nucleus undergoing deformation. It allows retrieving the displacement, strain and stress at each pixel of the nuclear domain, as well as the trac ...

Comprehensive analysis of the circadian nuclear and cytoplasmic transcriptome in mouse liver

Felix Naef, Cédric Gobet, Benjamin Dieter Weger, Clémence Yumie Syloun Hurni

In eukaryotes, RNA is synthesised in the nucleus, spliced, and exported to the cytoplasm where it is translated and finally degraded. Any of these steps could be subject to temporal regulation during the circadian cycle, resulting in daily fluctuations of ...

Sequence-dependent structural properties of B-DNA: what have we learned in 40 years?

John Maddocks, Daiva Petkeviciute, Rahul Sharma, Marco Pasi

The structure of B-DNA, the physiological form of the DNA molecule, has been a central topic in biology, chemistry and physics. Far from uniform and rigid, the double helix was revealed as a flexible and structurally polymorphic molecule. Conformational ch ...

Spatial control of nucleoporin condensation by fragile X-related proteins

Alessandro Berto

Nucleoporins (Nups) build highly organized nuclear pore complexes (NPCs) at the nuclear envelope (NE). Several Nups assemble into a sieve-like hydrogel within the central channel of the NPCs. In the cytoplasm, the soluble Nups exist, but how their assembly ...

Selective inhibition of STAT3 signaling using monobodies targeting the coiled-coil and N-terminal domains

Oliver Hantschel, Florence Pojer, Kelvin Ka Ching Lau, Tim Kükenshöner, Grégory La Sala

The transcription factor STAT3 is frequently activated in human solid and hematological malignancies and remains a challenging therapeutic target with no approved drugs to date. Here, we develop synthetic antibody mimetics, termed monobodies, to interfere ...

Organelle-specific targeting of polymersomes into the cell nucleus

Zekiye Pelin Güven

Organelle-specific nanocarriers (NCs) are highly sought after for delivering therapeutic agents into the cell nucleus. This necessitates nucleocytoplasmic transport (NCT) to bypass nuclear pore complexes (NPCs). However, little is known as to how comparabl ...

Quantitative relationships between SMAD dynamics and target gene activation kinetics in single live cells

Felix Naef, David Michael Suter, Torgil Elias Friman, Onur Tidin

The transduction of extracellular signals through signaling pathways that culminate in a transcriptional response is central to many biological processes. However, quantitative relationships between activities of signaling pathway components and transcript ...

Diverse roles of TssA-like proteins in the assembly of bacterial type VI secretion systems

Henning Paul-Julius Stahlberg, Sergey Nazarov

Protein translocation by the bacterial type VI secretion system (T6SS) is driven by a rapid contraction of a sheath assembled around a tube with associated effectors. Here, we show that TssA-like or TagA-like proteins with a conserved N-terminal domain and ...

MeCP2-E1 isoform is a dynamically expressed, weakly DNA-bound protein with different protein and DNA interactions compared to MeCP2-E2

Jose Vicente Sanchez Mut

Background: MeCP2-a chromatin-binding protein associated with Rett syndrome-has two main isoforms, MeCP2-E1 and MeCP2-E2, differing in a few N-terminal amino acid residues. Previous studies have shown brain region-specific expression of these isoforms whic ...
