Copper‐Driven Epithelial Barrier Disruption: A Novel Mechanism of COPD Acute Exacerbations Mediated by the TNF‐α/ATP7A Axis

Advanced Science, EarlyView.
This study reveals a copper‐driven mechanism of COPD acute exacerbations mediated by the TNF‐α/ATP7A axis. TNF‐α suppresses the copper transporter ATP7A via competitive NF‐κB/CREB1/CBP signaling, resulting in intracellular copper accumulation, mitochondrial oxidative stress, and epithelial barrier disruption.

Atrial TRPM2 Channel-Mediated Ca²⁺ Influx Regulates ANP Secretion and Protects Against Isoproterenol-Induced Cardiac Hypertrophy and Fibrosis

Cells
Transient receptor potential melastatin 2 (TRPM2) channel is a Ca2+-permeable, redox-activated cardiac ion channel protective in ischemia–reperfusion, but whether it regulates atrial endocrine output under stress is unclear. Here, we investigated whether

Downregulation of a novel long noncoding RNA TRPM2-AS promotes apoptosis in non–small cell lung cancer

Tumor Biology, 2017
Non–small cell lung cancer is one of the most common types of cancer, and the prognosis of non–small cell lung cancer is still poor. Recent evidence has proved that long noncoding RNA is involved in tumorigenesis.

An Extracellular Pore‑Targeting Peptide Defines a Designable Allosteric Site in TRPV2

Advanced Science, EarlyView.
Structure‐guided peptide engineering yields Depiv2, a highly potent and subtype‐selective TRPV2 inhibitor that binds to the extracellular pore and remodels it into a closed, non‐conductive state. Depiv2 suppresses pathological cardiac hypertrophy, establishing the TRPV2 outer pore as a designable interface for selective peptide modulation.

Ligand recognition and gating mechanism through three ligand-binding sites of human TRPM2 channel

eLife, 2019
TRPM2 is critically involved in diverse physiological processes including core temperature sensing, apoptosis, and immune response. TRPM2’s activation by Ca2+ and ADP ribose (ADPR), an NAD+-metabolite produced under oxidative stress and neurodegenerative

Keeping It Native: Non‐Denaturing Approaches to Top‐Down Protein Mass Spectrometry

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Top‐down proteomics and top‐down mass spectrometry approaches provide direct characterization of proteoforms; the specific molecular forms of proteins, including post‐translational modifications, truncations, alternative splicing, and sequence variants.

Identification of novel sense and antisense transcription at the TRPM2 locus in cancer

, 2008
It has been proposed that in cancer, where the bulk of the genome becomes hypomethylated, there is an increase in transcriptional noise that might lead to the generation of antisense transcripts that could affect the function of key oncosuppressor genes,

Protective Potentials of Natural Products Against Vascular Dementia: A Comprehensive Review of Experimental Studies

Phytotherapy Research, EarlyView.
ABSTRACT Vascular dementia (VaD), accounting for up to 20% of dementia cases globally, is primarily driven by chronic cerebral hypoperfusion (CCH), which leads to progressive cognitive impairment. Despite the increasing prevalence of VaD, effective treatments remain limited.

Geographical Variation in Thermal Adaptation of the Asiatic Toad (Bufo gargarizans)

Integrative Zoology, EarlyView.
Northern and southern populations of Bufo gargarizans exhibit coordinated divergence in thermal preference, resting metabolic rate, and TRPM4 temperature sensitivity along a climatic gradient. ABSTRACT Thermal adaptation in animals can manifest in multiple dimensions, yet few studies have integrated behavioral, physiological, and molecular perspectives

Distinctly altered TRPC3 and TRPC6 expression patterns in human Alzheimer's disease cortex and hippocampus

Brain Pathology, EarlyView.
Divergent remodeling of TRPC channels occurs in Alzheimer's disease, with TRPC3 increased in neurons and reactive astrocytes and TRPC6 reduced in pyramidal neurons. These alterations may contribute to calcium dysregulation, neuroinflammation, and synaptic dysfunction during AD progression.
