High matrix stiffness promotes senescence of type II alveolar epithelial cells by lysosomal degradation of lamin A/C in pulmonary fibrosis

Respiratory Research
Background Cellular senescence is one of the key steps in the progression of pulmonary fibrosis, and the senescence of type II alveolar epithelial cells (AEC IIs) may potentially accelerate the progression of pulmonary fibrosis.

Proteostasis of organelles in aging and disease

The FEBS Journal, EarlyView.
Cells rely on regulated proteostasis mechanisms to keep their internal compartments functioning properly. When these mechanisms fail, damaged proteins accumulate, disrupting organelles, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi, and lysosomes, as well as membraneless organelles, such as stress granules, processing bodies, the ...

Disruption of iron metabolism resulting from Dmt1/Slc11a2 deficiency compromises Notch protein degradation and transcriptional activation

The FEBS Journal, EarlyView.
Divalent metal transporter 1 (Dmt1) maintains iron homeostasis and lysosomal proteostasis required for physiological Notch receptor–ligand signaling. Dmt1 loss lowers iron storage capacity (ferritin), increasing intracellular Fe2+, driving ROS and lipid peroxidation, and leading to lysosomal/mitochondrial dysfunction.

Chd4 and ThPOK cooperate to preserve structural and electrophysiological integrity of the adult heart through Sprr1a repression

The FEBS Journal, EarlyView.
Chd4/NuRD and ThPOK cooperate to maintain transcriptional repression and nuclear organization in adult cardiomyocytes. Chd4 loss reduces miR‐150‐5p, relieving repression of Sprr1a, while ThPOK loss further enhances Sprr1a activation, possibly through altered chromatin–lamina interactions.

Extracellular fluid viscosity influences the mechanics and migration of MDA‐MB‐231 cells in a macromolecule‐dependent manner

The FEBS Journal, EarlyView.
Macromolecule‐dependent increases in extracellular fluid viscosity alter cell phenotype. These distinct macromolecules create different extracellular environments that modulate cell morphology and mechanoprotein expression, migration and invasion capacity, and cellular mechanical properties.

Protective effects of extracellular vesicle‐like nanoparticles derived from Cannabis sativa adventitious roots against UVB‐induced damage in human keratinocytes

International Journal of Cosmetic Science, EarlyView.
Cannabis sativa root‐derived extracellular vesicle‐like nanoparticles (CA‐NPs) were isolated from adventitious root cultures and subjected to physicochemical characterization. Upon UVB exposure, keratinocytes exhibited increased ROS generation, apoptosis and MAPK activation, leading to oxidative stress and skin damage.

Leave It to Me: Overconfident CEOs’ Lower Propensity to Delegate Acquisition Responsibility

Journal of Management Studies, EarlyView.
Abstract Overconfident CEOs have been shown to lead their firms to achieve different outcomes, but the literature has only a limited understanding why this is the case. In this paper, we focus on whether overconfident CEOs run their firms differently, focusing on a key internal interaction: CEOs' choices regarding whether to delegate to other ...

SIRT2 Inhibition by AGK2 Promotes Perinuclear Cytoskeletal Organisation and Reduces Invasiveness of MDA-MB-231 Triple-Negative Breast Cancer Cells in Confined In Vitro Models

Cells
Triple-negative breast cancer (TNBC) is a highly aggressive breast cancer subtype characterised by the absence of targetable hormone receptors and increased metastatic rates.

Parenthood and CEO Responses to Media Criticism on Pay

Journal of Management Studies, EarlyView.
Abstract Research on media coverage of controversial corporate practices typically suggests firms respond instrumentally to mitigate stakeholder reactions. However, we argue that CEOs' moral concerns can sometimes override strategic considerations, because media criticism may expose them to scrutiny from personally valued audiences – for instance ...

Recruitment in Times of Crisis: The Impact of Negative Signals and CSR on Job Seekers' Attraction to Multinational Enterprises

Journal of Management Studies, EarlyView.
Abstract Recruitment research has traditionally focused on how positive signals about organizations influence job seekers' perceptions and attraction to them, despite the fact that job seekers often encounter a mix of positive and negative information about prospective employers.
