Organ Specificity and Commonality of Epigenetic Aging in Low‐ and High‐Running Capacity Rats

open access: yesAging Cell, EarlyView.
Cardiorespiratory fitness (CRF) is not associated with epigenetic clocks, including newly developed ones. On the other hand, CRF is associated with global methylation profiles and promoter methylation in organ‐specific and organ‐common manner. ABSTRACT Epigenetic drift, which is gradual age‐related changes in DNA methylation patterns, plays a ...

A cellular model of TDP‐43 induces phosphorylated TDP‐43 aggregation with distinct changes in solubility and autophagy dysregulation

open access: yesThe FEBS Journal, EarlyView.
TDP‐43 protein plays a pathological role in sporadic and familial amyotrophic lateral sclerosis (ALS). Here, we developed a cellular model overexpressing TDP‐43 with three mutations linked to familial ALS, termed ‘3X‐TDP‐43’. Mutant 3X‐TDP‐43 expression showed deficits in autophagy flux and colocalization with stress granules.

Two structurally distinct domains of the nucleoporin Nup170 cooperate to tether a subset of nucleoporins to nuclear pores [PDF]

open access: yesJournal of Cell Biology, 2009
How individual nucleoporins (Nups) perform their role in nuclear pore structure and function is largely unknown. In this study, we examined the structure of purified Nup170 to obtain clues about its function. We show that Nup170 adopts a crescent moon shape with two structurally distinct and separable domains, a β-propeller N terminus and an α-solenoid

Redox-Sensitive Cysteines Confer Proximal Control of the Molecular Crowding Barrier in the Nuclear Pore

open access: yesCell Reports, 2020
Summary: The nuclear pore complex forms a highly crowded selective barrier with intrinsically disordered regions at the nuclear membrane to coordinate nucleocytoplasmic molecular communications.

A CRISPR‐Cas9‐based system for the dose‐dependent study of DNA double‐strand break sensing and repair

open access: yesThe FEBS Journal, EarlyView.
Using CRISPR‐Cas9, we engineered a genetic system allowing the dose‐dependent induction of a controllable number of DNA double‐strand breaks in Saccharomyces cerevisiae. The tool was used to study the kinetics of DNA break sensing and repair, including the spatial distribution of Tel1ATM kinase, which initiates the DNA damage response.

In vivo modeling of lethal congenital contracture syndrome 1 suggests pathomechanisms in cellular stress responses

open access: yesThe FEBS Journal, EarlyView.
Gle1 knockout mice fail to segregate cell lineages at the blastocyst stage, resulting in very early embryonic lethality. Gle1 knock‐in (KI) mice harboring a pathogenic variant giving rise to lethal congenital contracture syndrome 1 show both known and novel innervation defects, supportive of multiorgan pathology in human fetuses.

Complex Commingling: Nucleoporins and the Spindle Assembly Checkpoint [PDF]

open access: yesCells, 2015
The segregation of the chromosomes during mitosis is an important process, in which the replicated DNA content is properly allocated into two daughter cells. To ensure their genomic integrity, cells present an essential surveillance mechanism known as the spindle assembly checkpoint (SAC), which monitors the bipolar attachment of the mitotic spindle ...

Cell type‐specific nuclear pores: a case in point for context‐dependent stoichiometry of molecular machines

open access: yesMolecular Systems Biology, 2013
To understand the structure and function of large molecular machines, accurate knowledge of their stoichiometry is essential. In this study, we developed an integrated targeted proteomics and super‐resolution microscopy approach to determine the absolute

Genotyping by Amplicon Sequencing (GBAS) With Newly Developed SSR and EPIC Markers Reveals Structure in Populations of the Green Toad (Bufotes viridis) Across Rural and Urban Environments

open access: yesEcology and Evolution, Volume 15, Issue 7, July 2025.
We developed and tested SSR and EPIC markers for the green toad (Bufotes viridis), demonstrating their effectiveness using genotyping by high‐throughput amplicon sequencing (GBAS) across urban and rural populations. EPIC markers exhibited fewer null alleles and provided more ecologically coherent clustering results, while SSRs reflected drift‐induced ...

Evolution of a transcriptional regulator from a transmembrane nucleoporin [PDF]

open access: yesGenes & Development, 2016
Nuclear pore complexes (NPCs) emerged as nuclear transport channels in eukaryotic cells ∼1.5 billion years ago. While the primary role of NPCs is to regulate nucleo–cytoplasmic transport, recent research suggests that certain NPC proteins have additionally acquired the role of affecting gene expression at the nuclear periphery and in the nucleoplasm in
