Tetrodotoxin, fungal pathogen infection, and bacterial microbiome associations are variable in the skin microecosystems of two Taricha newt species

Frontiers in Amphibian and Reptile Science
A diverse metabolome exists on amphibian skin that mediates interactions between hosts and skin microbiomes. Tetrodotoxin is one such metabolite that occurs across a variety of taxa, and is particularly well studied in newts of the genus Taricha that are

6‐Nitrodopamine as a Novel Mediator of Prostatic Smooth Muscle Function in Mouse and Human

Andrology, EarlyView.
ABSTRACT Background Epithelium‐derived catecholamines contribute to local regulation of genitourinary smooth muscle function, but the role of the endogenous 6‐nitrodopamine (6‐ND) in the prostate remains unknown. Objectives To determine whether 6‐ND is produced by mouse and human prostate and its role in smooth muscle regulation.

Comparative Transcriptome Analysis of Toxic and Non-Toxic Nassarius Communities and Identification of Genes Involved in TTX-Adaptation

Toxins, 2020
Nassarius has caused serious people poisoning and death incident as a popular food due to tetrodotoxin (TTX) accumulation in their body. Understanding the genetic basis of tetrodotoxin (TTX) transformation and resistance in animals could lead to ...

Cancer pain: current practice and emerging targets

British Journal of Pharmacology, EarlyView.
Cancer pain (CP) arises from a complex interplay between the tumour and its microenvironment. Many patients experience a mixed pain phenotype that encompasses nociceptive, neuropathic and neuroinflammatory mechanisms, and vary across tumour type and disease stage. Despite decades of intensive research, the mainstay of cancer pain treatment is still non‐

Inhibition of late sodium current prevents pathological hyperactivation of calcium/calmodulin‐dependent protein kinase IIδ in a murine model of acute doxorubicin‐related cardiotoxicity

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Doxorubicin (DOX) is a highly effective anthracycline, whose clinical application for cancer is limited by cardiotoxicity. The mechanisms underlying doxorubicin‐induced toxic cardiomyopathy (DICM) involve electrophysiological remodelling with intracellular Na+ overload because of increased late INa and hyperactivation of

An improved competitive inhibition enzymatic immunoassay method for tetrodotoxin quantification

Biological Procedures Online, 2012
Quantifying tetrodotoxin (TTX) has been a challenge in both ecological and medical research due to the cost, time and training required of most quantification techniques.

Potentiation effects of the positive allosteric modulator PTC‐174 on NMDA receptors in neonatal male rat substantia nigra dopaminergic neurons

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Positive allosteric modulators bind to secondary binding sites on the receptor and alter receptor conformation and activation, changing agonist potency and efficacy. PTC‐174 is a novel NMDA receptor positive allosteric modulator that particularly enhances activity of receptors containing GluN2C or GluN2D subunits.

Selective modulation of NaV channel gating counteracts aberrant hyperexcitability and rescues motor function and survival in a model of spinal muscular atrophy

British Journal of Pharmacology, EarlyView.
Background and Purpose Spinal muscular atrophy (SMA) is a motor neuron disease caused by SMN1 gene loss, leading to reduced survival motor neuron (SMN) protein and progressive motor neuron degeneration. Although SMN‐restoring therapies improve outcomes, residual disease burden and non‐curative efficacy underscore the need for complementary treatments ...

Tetrodotoxin-resistant sodium channels in neuropathic pain

, 2000
Injury to the peripheral nervous system can cause neuropathic pain. Abnormal sodium channel activity has been implicated as a source of ectopic firing and changes in nociceptive threshold following nerve injury.
