Comparative Analysis of Heat Exposure‐Induced Molecular Changes in Two Turtle Species with Contrasting Thermal Adaptations

Integrative Zoology, EarlyView.
Protein processing in the endoplasmic reticulum is highlighted in response to heat stress in Platysternon megacephalum. Under heat stress, the up‐regulation of genes such as CHOP in protein processing in the endoplasmic reticulum pathway, along with the suppression of energy and lipid metabolism and the up‐regulation of JARID2 expression, leads to ...

Myosin II isoforms play distinct roles in adherens junction biogenesis

eLife, 2019
Adherens junction (AJ) assembly under force is essential for many biological processes like epithelial monolayer bending, collective cell migration, cell extrusion and wound healing. The acto-myosin cytoskeleton acts as a major force-generator during the

Elevated CO2 and Temperature Alter Grass Pollen's Ability to Modify Transcriptome and Function of the Nasal Epithelium

Allergy, EarlyView.
We exposed human nasal epithelial tissues to pollen from grasses grown under different climate treatments (temperature and CO2). Pollen weakened epithelial tight junctions and altered cytokine‐related gene expression, with similar protein‐level effects.

Force-dependent vinculin binding of α-catenin accelerates adherens junction formation

Cell Structure and Function
Adherens junctions (AJs) mediate cell–cell adhesion and mechanical coupling in epithelial tissues. During AJ formation, punctate AJs (punctum adherens; PA) initially appear and subsequently transition into linear AJs or zonula adherens (ZAs).

Integrated Methylome–Transcriptome Analysis Reveals Epigenomic Remodeling and Rho GTPase–Linked Immune–Epithelial Crosstalk in Atopic Dermatitis

Allergy, EarlyView.
Integrated methylome–transcriptome–microbiome analysis of AD skin identified thousands of DMRs. Rho GTPase signaling and actin–junctional programs emerged as central hubs integrating immune, epithelial, and microbial interactions in the pathogenesis of atopic dermatitis.

The Functional Role and Molecular Characterization of the Therapeutic Target CLDN6 in Germ Cell Tumors

Andrology, EarlyView.
ABSTRACT Background The tight junction protein CLDN6 has been identified as a cancer‐associated cell surface marker that is rarely expressed in healthy tissues. In testicular germ cell tumors (GCT), CLDN6 is particularly detectable in seminomas, embryonal carcinomas, and choriocarcinomas.

Deep-brain stimulation associates with improved microvascular integrity in the subthalamic nucleus in Parkinson's disease

Neurobiology of Disease, 2015
Deep brain stimulation (DBS) of the subthalamic nucleus (STN) has become an accepted treatment for motor symptoms in a subset of Parkinson's disease (PD) patients. The mechanisms why DBS is effective are incompletely understood, but previous studies show

A multicentre analysis of efficacy, safety and molecular response correlates of fostamatinib in warm autoimmune haemolytic anaemia and Evans syndrome

British Journal of Haematology, EarlyView.
Fostamatinib had 46% durable response, with 73% steroid reduction, in this multicentre retrospective study of refractory wAIHA/ES. Hypertension, gastrointestinal (GI) distress and neutropenia occurred in 23%. Only one patient required drug discontinuation and one patient dose reduction.

Diversity of Intercellular Communication Modes: A Cancer Biology Perspective

Cells
From the moment a cell is on the path to malignant transformation, its interaction with other cells from the microenvironment becomes altered. The flow of molecular information is at the heart of the cellular and systemic fate in tumors, and various ...

Transforming Growth Factor β/activin signalling induces epithelial cell flattening during Drosophila oogenesis

Biology Open, 2015
Although the regulation of epithelial morphogenesis is essential for the formation of tissues and organs in multicellular organisms, little is known about how signalling pathways control cell shape changes in space and time.
