Brain Pericytes and Wnt/β‐Catenin Signaling Induce Functional Blood–Brain Barrier Phenotype in Human iPSC‐Derived Model

Small Methods, EarlyView.
This study shows that human iPSC‐derived endothelial cells acquire a functional blood–brain barrier phenotype when co‐cultured with brain pericytes and stimulated with CHIR‐99021, a Wnt/β‐catenin activator. This model recapitulates key barrier properties, inflammatory responses, and transcriptomic features of the native human BBB, offering new ...

PKCα and CPI-17 expression and spatial-temporal distribution with activation in pig stomach antrum and fundus [PDF]

, 2010
Smooth muscle contraction is a complicated process coordinated by contractile, regulatory and cytoskeletal proteins. The force generation depends on the phosphorylation of Myosin Regulatory Light Chain (MLC20). Myosin Light Chain Kinase (MLCK) and Myosin

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 ...

Role of airway epithelial barrier dysfunction in pathogenesis of asthma

Allergology International, 2018
Bronchial asthma is characterized by persistent cough, increased sputum, and repeated wheezing. The pathophysiology underlying these symptoms is the hyper-responsiveness of the airway along with chronic airway inflammation.

Cellular Stress, Inflammation and Barrier Damage in Gut Epithelial Cells Caused by Aspartame

Allergy, EarlyView.
This study shows that aspartame, at dietary‐relevant doses, induces cytotoxicity, cellular distress associated with endoplasmic reticulum stress, oxidative stress, DNA replication and repair mechanism disturbance culminating in epithelial barrier damage.

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 ...

The T-type voltage-gated Ca2+ channel CaV3.1 involves in the disruption of respiratory epithelial barrier induced by Pasteurella multocida toxin

Virulence
Pasteurella multocida toxin (PMT) is an exotoxin produced by several members of the zoonotic respiratory pathogen P. multocida. The role of PMT in disrupting the mammalian respiratory barrier remains to be elucidated.

The polarized expression of Na+,K+-ATPase in epithelia depends on the association between beta-subunits located in neighboring cells [PDF]

, 2005
The polarized distribution of Na+,K+-ATPase plays a paramount physiological role, because either directly or through coupling with co- and countertransporters, it is responsible for the net movement of, for example, glucose, amino acids, Ca2+, K+, Cl ...

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.

Endocrine Resistance Score Based on Three Key Genes Predicts Prognosis and Reveals Potential Therapeutic Targets for ER+HER2− Breast Cancer

Cell Proliferation, EarlyView.
We generated endocrine‐resistant BC cell lines and identified CLEC3A, PCDH10, and ST3GAL1 as key endocrine‐resistant genes. More importantly, we validated their role in mediating resistance through PI3K‐AKT signalling and developed a predictive ERS with strong clinical relevance.
