Zebrafish models of genetic epilepsy benefit from the ability to assess disease-relevant knock-out alleles with numerous tools, including genetically encoded calcium indicators (GECIs) and hypopigmentation alleles to improve visualization. However, there may be unintended effects of these manipulations on the phenotypes under investigation. There is also debate regarding the use of stable loss-of-function (LoF) alleles in zebrafish, due to genetic compensation (GC).

Loss of PKD2L1 expression results in seizure-susceptibility and autism-like features in mice, whereas variants in PKD2 cause autosomal dominant polycystic kidney disease. Despite decades of evidence clearly linking their dysfunction to human disease and demonstrating their physiological importance in the brain and kidneys, the polycystin pharmacophore remains undefined.

Background: Mounting evidence underline the relevance of macromolecular complexes in cancer. Integrins frequently recruit ion channels and transporters within complexes which behave as signaling hubs. A complex composed by β1 integrin, hERG1 K channel, the neonatal form of the Na channel Na 1.

Chemotherapy-induced neuropathic pain poses significant clinical challenges and severely impacts patient quality of life. Sodium ion channels are crucial in regulating neuronal excitability and pain. Our research indicates that the microRNA-30b (miR-30b) in rat dorsal root ganglia (DRG) contributes to chemotherapy-induced neuropathic pain by regulating the Nav1.

Burn-related neuropathic pain (BRNP) can arise following burn-induced nerve damage, affects approximately 6% of burned human patients and can result in chronic pain. Although widely studied in humans, data on BRNP or its treatment in animals is lacking. A 4-year-old domestic shorthair cat was presented with an infected, non-healing wound suspected to be a caustic burn.
