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.

HIF2α-dependent Dock4/Rac1-signaling regulates formation of adherens junctions and cell polarity in normoxia

Scientific Reports
Hypoxia-inducible factors (HIF) 1 and 2 regulate similar but distinct sets of target genes. Although HIFs are best known for their roles in mediating the hypoxia response accumulating evidence suggests that under certain conditions HIFs, particularly ...

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.

Rab7a is required to degrade select blood-brain barrier junctional proteins after ischemic stroke

Acta Neuropathologica Communications
The integrity of adherens and tight junctions is critical for blood-brain barrier (BBB) function in the healthy brain. Disassembly of cell junctions due to degradation of adherens and tight junction-associated proteins leads to acute BBB dysfunction ...

Microtubule-dependent balanced cell contraction and luminal-matrix modification accelerate epithelial tube fusion

Nature Communications, 2016
During tracheal tube fusion in Drosophila, a pair of tip cells form an adherens junction and then fuse their plasma membranes. Here the authors show that a balanced pulling force mediated by myosin and microtubules, as well as localized deposition of ...

MPDZ promotes DLL4-induced Notch signaling during angiogenesis

eLife, 2018
Angiogenesis is coordinated by VEGF and Notch signaling. DLL4-induced Notch signaling inhibits tip cell formation and vessel branching. To ensure proper Notch signaling, receptors and ligands are clustered at adherens junctions.

The nitty‐gritty of vascular permeability in cancer: targeting blood endothelium to control metastases

British Journal of Pharmacology, EarlyView.
Blood vascular permeability is a hallmark of cancer and acts as an active driver of metastatic dissemination. Metastasis accounts for the vast majority of cancer deaths, yet most work has focussed on tumour‐intrinsic traits and angiogenesis, while the specific contribution of endothelial barrier regulation to intravasation and extravasation remains ...

Mtss1 promotes cell-cell junction assembly and stability through the small GTPase Rac1.

PLoS ONE, 2012
Cell-cell junctions are an integral part of epithelia and are often disrupted in cancer cells during epithelial-to-mesenchymal transition (EMT), which is a main driver of metastatic spread.

Epithelial YPEL3 Modulates CD8+ T‐Cell Infiltration and Tumor Progression Through CREB1–CXCL16 Signaling in HNSCC

Cancer Science, EarlyView.
YPEL3 functions as a tumor suppressor in HNSCC by inhibiting tumor progression and promoting apoptosis. Mechanistically, it enhances epithelial–immune crosstalk through the CREB1‐mediated CXCL16–CXCR6 axis, facilitating CD8+ T‐cell infiltration and highlighting its potential as a prognostic biomarker and immunotherapy target.
