A Unified Linear Viscoelastic Model of the Cell Nucleus Defines the Mechanical Contributions of Lamins and Chromatin

Advanced Science, 2020
The cell nucleus is constantly subjected to externally applied forces. During metazoan evolution, the nucleus has been optimized to allow physical deformability while protecting the genome under load.

Timing Mechanotransduction: Mechanically Dynamic Biomaterials Reveal the Temporal Hierarchy of YAP/TAZ Control Nodes

Advanced Science, EarlyView.
This work develops dynamically softening polyacrylamide hydrogels for time‐resolved imaging during continuous mechanical transitions. The study revealed that mechanotransduction is biphasic; YAP/TAZ inactivation is driven by early loss of the nucleocytoskeletal continuum connecting subnuclear adhesions, F‐actin, and the nuclear envelope, coupled with ...

The Regulatory Role of Iron Transporter SLC39A13 in Liver Fibrosis

Advanced Science, EarlyView.
SLC39A13/ZIP13, a newly discovered intracellular iron transporter, delivers iron to the ER/Golgi to catalyze procollagen hydroxylation during collagen maturation. Here, we systematically characterize the cell type‐specific functions of ZIP13 across distinct hepatic cell populations, and identify hepatic stellate cell‐specific ZIP13 as a promising and ...

Novel PMVs/ZIP4/Zinc/Prelamin A Axis Promotes Nuclear Dysmorphism and Vascular Aging in Humans and Rodents Post-Injury: Effective Treatment With Platelet Membrane-Coated ZIF-8 Nanoparticles. [PDF]

Aging Cell
Interventional therapy and surgical injury induce nuclear dysmorphism and vascular aging. Nuclear dysmorphism is positively associated with vascular aging. Novel PMVs/ZIP4/Zinc/preLamin A axis plays a key role in injury‐induced nuclear dysmorphism and vascular aging.

BCR::ABL1‐Induced Enhancer Reprogramming Uncovers Hypersensitivity of Ph+B‐ALL Cells to Enhancer‐Targeting Drugs

Advanced Science, EarlyView.
Ng et al. show that the BCR::ABL1 kinase that drives the lymphoid leukemia Ph+B‐ALL modulates enhancer function by coopting signaling‐inducible transcription factors such as MYC, STAT5, and ETV5. BCR::ABL1 thereby promotes the transcriptional program driving and defining this leukemia and renders Ph+B‐ALL cells hypersensitive to enhancer‐inhibiting ...

The Emerging Role of Lamin C as an Important LMNA Isoform in Mechanophenotype

Frontiers in Cell and Developmental Biology, 2018
Lamin A and lamin C isoforms of the gene LMNA are major structural and mechanotransductive components of the nuclear lamina. Previous reports have proposed lamin A as the isoform with the most dominant contributions to cellular mechanophenotype. Recently,

Nuclear shape is affected differentially by loss of lamin A, lamin C, or both lamin A and C

microPublication biology
Lamin intermediate filaments form a peripheral meshwork to support nuclear shape and function. Knockout of the LMNA gene that encodes for both lamin A and C results in an abnormally shaped nucleus. To determine the relative contribution of lamin A and C to nuclear shape, we measured nuclear blebbing and circular deviation in separate lamin A and lamin ...

Intracellular Aβ42 Sequestration by a Serine Protease Mitigates Neurotoxicity in a Drosophila Alzheimer's Disease Model

Advanced Science, EarlyView.
Emerging evidence suggests that intraneuronal Aβ accumulation represents an early pathogenic event in Alzheimer's disease (AD). Using Drosophila AD model, this study shows that a nonsecreted serine protease Yip7 physically interacts with Aβ. This causes intraneuronal Aβ accumulation but surprisingly reduces the associated neurotoxicity, arguing that ...

Context‐Dependent Role of GDF15: GDF15+ Tumor‐Associated Macrophages Suppress OSCC Progression by Enhancing Phagocytosis

Advanced Science, EarlyView.
This study identifies GDF15+ TAMs as a cell subset mediating tumor regression after immunotherapy. Macrophage‐intrinsic GDF15 enhances phagocytosis and antigen cross‐presentation to CD8+ T cells through the NF‐κB signaling pathway, thereby inhibiting tumor progression.

Liver Stiffness Rises Early in MASLD and Drives Inflammation, Lipid Dysmetabolism, and Fibrosis via Piezo1–YAP Mechanotransduction

Advanced Science, EarlyView.
Progressive stiffening of the hepatic extracellular matrix and free fatty acid overload activate the mechanosensor Piezo1 in steatotic hepatocytes, inducing calcium influx and nuclear translocation of Yes‐associated protein. YAP‐dependent nuclear signaling further drives inflammatory and fibrotic gene programs, lipid metabolic reprogramming, and ...
