The inner nuclear membrane protein Sun1 mediates the anchorage of Nesprin-2 to the nuclear envelope [PDF]

Journal of Cell Science, 2005
Nesprins form a novel class of nuclear envelope-anchored spectrin-repeat proteins. We show that a direct association of their highly conserved C-terminal luminal domain with the inner nuclear membrane protein Sun1 mediates their nuclear envelope localisation.

Neural Organoid Models as a Platform for Studying Disease Mechanisms in Amyotrophic Lateral Sclerosis

Journal of Neurochemistry, Volume 170, Issue 7, July 2026.
Amyotrophic lateral sclerosis (ALS) involves widespread cortical pathology beyond the motor cortex. Human‐induced pluripotent stem cell‐derived neural organoids model cortical tissue in vitro and provide a physiologically relevant platform to study disease mechanisms in ALS.

Nuclear Entanglement: New Insights Into the Role of Cytoskeleton and Nucleoskeleton in Plant Nuclear Function

Cytoskeleton, Volume 83, Issue 6, Page 354-375, June 2026.
ABSTRACT Of the three types of cytoskeleton known in animals—actin, microtubules, and intermediate filaments—only actin and microtubules exist in plants. Both play important roles in cellular shaping, organelle movement, organization of the endomembrane system, and cell signaling.

A molecular mechanism for LINC complex branching by structurally diverse SUN-KASH 6:6 assemblies

eLife, 2021
The Linker of Nucleoskeleton and Cytoskeleton (LINC) complex mechanically couples cytoskeletal and nuclear components across the nuclear envelope to fulfil a myriad of cellular functions, including nuclear shape and positioning, hearing, and meiotic ...

Inner Nuclear Envelope Proteins SUN1 and SUN2 Play a Prominent Role in the DNA Damage Response [PDF]

Current Biology, 2012
The DNA damage response (DDR) and DNA repair are critical for maintaining genomic stability and evading many human diseases. Recent findings indicate that accumulation of SUN1, a nuclear envelope (NE) protein, is a significant pathogenic event in Emery-Dreifuss muscular dystrophy and Hutchinson-Gilford progeria syndrome, both caused by mutations in ...

Current Topics of Progressive Cardiac Conduction Disease

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
Many genes and the protein cause PCCD. Mutation of NaV1.5 or CX40 cause isolated PCCD, but mutation of lamin A/C, emerin, or desmin lead to cardiomyopathy, and PCCD. Mutation of transcription factor NCX2‐5, and Tbx5 associated with atrial septal defect and abnormal development of conduction system.

Human Telomeres Are Tethered to the Nuclear Envelope during Postmitotic Nuclear Assembly

Cell Reports, 2012
Telomeres are essential for nuclear organization in yeast and during meiosis in mice. Exploring telomere dynamics in living human cells by advanced time-lapse confocal microscopy allowed us to evaluate the spatial distribution of telomeres within the ...

Gastric Cancer: Pathobiology and Therapeutics

MedComm, Volume 7, Issue 6, June 2026.
Gastric cancer is a multistep process driven by the interplay of microbial virulence, host epithelial injury, and evolving molecular reprogramming. Initiation involves pathogen‐induced epigenetic alterations and the early subversion of key oncogenic signaling networks, facilitating the transition from chronic injury to metaplasia and malignant ...

Mechanism and Regulation of Rapid Telomere Prophase Movements in Mouse Meiotic Chromosomes

Cell Reports, 2015
Telomere-led rapid prophase movements (RPMs) in meiotic prophase have been observed in diverse eukaryote species. A shared feature of RPMs is that the force that drives the chromosomal movements is transmitted from the cytoskeleton, through the nuclear ...

Nuclear Mechanotransduction Across the Metastatic Cascade: Decoding Spatiotemporal Heterogeneity in Cancer Dissemination

Advanced Science, Volume 13, Issue 25, 4 May 2026.
Tumor metastasis results from complex interactions between cancer cells and mechanical microenvironments. We propose a “nucleus‐centered, cross‐stage mechanical signal decoding” model, highlighting how nuclear mechanosensors interpret forces at different stages.
