Deficiency of Mitochondrial Fatty Acid Enzyme, CPT1A, Underlies Airway Epithelial Barrier Dysfunction in Severe Asthma

open access: yesAllergy, EarlyView.
Mitochondrial fatty acid enzyme, CPT1A, is deficient in the airway epithelium of severe asthma patients. Restoration of CPT1A expression improved epithelial barrier integrity via increasing mitochondrial respiration and ATP production in airway epithelial cells. Restoration of deficient epithelial CPT1A may represent a new treatment approach for severe

Loss‐of‐Function Variants in CCDC189 Cause Human Oligoasthenoteratozoospermia by Disrupting Sperm Flagellar and Acrosomal Architecture

open access: yesAndrology, EarlyView.
ABSTRACT Background Oligoasthenoteratozoospermia (OAT), characterized by reduced sperm count, impaired motility, and abnormal morphology, is a major cause of male infertility with substantial genetic heterogeneity. However, the underlying genetic etiology remains unresolved in a large proportion of affected individuals.

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

open access: yesBritish 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 ...

Peripheral κ opioid receptor in pain and inflammation: From molecular signalling and gene expression to drug discovery

open access: yesBritish Journal of Pharmacology, EarlyView.
The κ opioid receptor (κ receptor, KOR) is a G protein‐coupled receptor with well established roles in analgesia and immune modulation. Although historically studied primarily in the central nervous system (CNS), growing evidence indicates that κ signalling in peripheral tissues plays an important role in regulating pain, inflammation and immune ...

Periodontitis‐Associated Circulating EVs Promote Colorectal Cancer Progression via Carnosine‐Mediated Acidosis Adaptation

open access: yesCell Proliferation, EarlyView.
This study identifies a link between periodontitis and CRC progression mediated by carnosine‐enriched circulating EVs. These EVs target the intestine and elevate tumour cell intracellular pH (pHi), which rescues lysosomal function. This process drives a transition from dysfunctional lysosomes to functional ones, promoting a high malignancy phenotype in
