Stressor‐ and Tissue‐Specific Regulation of the Corticotropin‐Releasing Factor System Across Epithelial Tissues in Rainbow Trout

The FASEB Journal, Volume 40, Issue 17, 15 September 2026.
The gill and intestinal corticotropin‐releasing factor (CRF) systems in rainbow trout are differentially regulated by immune, osmotic, and nutritional stressors. Seawater transfer suppressed gill CRF system transcription and induced time‐dependent changes in the middle intestine. An immune challenge (vaccination) altered only intestinal CRF expression.

Pemt Inhibition‐Mediated Vdac1 Oligomerization Regulates Mitochondrial Dysfunction, Apoptosis, and Inflammation in High‐Fat Diet‐Derived Liver Injury

Advanced Science, Volume 13, Issue 50, 7 September 2026.
ABSTRACT High‐fat diet (HFD)‐induced hepatic injury represents a pathology observed across vertebrates, yet the underlying mechanisms remain incompletely understood. Herein, the present study identifies phosphatidylethanolamine methyltransferase (Pemt), a key enzyme in phosphatidylcholine synthesis, as a critical regulator of mitochondrial homeostasis ...

Functional morphology of the pharyngeal teeth of the ocean sunfish, Mola mola

The Anatomical Record, Volume 309, Issue 9, Page 2286-2297, September 2026.
Abstract Many fish use a set of pharyngeal jaws in their throat to aid in prey capture and processing, particularly of large or complex prey. In this study—combining dissection, CT scanning, histology, and performance testing—we demonstrate a novel use of pharyngeal teeth in the ocean sunfish (Mola mola), a species for which pharyngeal jaw anatomy had ...

Ordered Chaos: Photoreceptor Mosaics in the Larval and Adult Turquoise Killifish (Nothobranchius furzeri)

Journal of Comparative Neurology, Volume 534, Issue 9, September 2026.
The annual turquoise killifish (Nothobranchius furzeri) cone photoreceptor mosaic is an ordered lattice but lacks regularity of cone subtypes in adulthood. The cone mosaic differs between life stages and has characteristics observed in other fishes adapted for life in turbid water.

Genomics Detects Japanese and Pacific Sardine (Sardinops spp.) Hybrids in the Northeast Pacific Ocean

Ecology and Evolution, Volume 16, Issue 9, September 2026.
Using a newly developed nuclear Genotyping‐in‐Thousands‐by‐sequencing (GT‐seq) panel that unambiguously differentiates Japanese and Pacific Sardine, we report the first detection of Sardinops spp. hybrids. Previous genomic analyses of Pacific Sardine in the Northeast Pacific detected the presence of Japanese Sardine along the west coast of North ...
