A Journey through the Gonadotropin-Inhibitory Hormone System of Fish

Frontiers in Endocrinology, 2017
Gonadotropin-inhibitory hormone (GnIH) is a hypothalamic neuropeptide that belongs to the RFamide peptide family and was first identified in the quail brain.

One‐step generation of heritable mitochondrial DNA multiplex‐engineered rats using DddA‐derived cytosine base editor

Animal Models and Experimental Medicine, EarlyView.
We established that mixed DdCBE microinjection is an efficient, heritable, and precise strategy for generating multiplex mtDNA mutant rats. This advancement significantly expands the utility of DdCBEs for mitochondrial disease modeling, providing a robust platform for exploring the pathogenic mechanisms of complex mtDNA mutations and developing ...

Evaluation of therapeutic effects of D‐limonene following orchiopexy in the rat model of cryptorchidism

Animal Models and Experimental Medicine, EarlyView.
D‐limonene supplementation enhances testicular recovery following orchiopexy in a rat model of bilateral cryptorchidism. Treatment with D‐limonene reduces oxidative stress (↓MDA, ↑SOD, ↑GPx, ↑TAC), downregulates pro‐apoptotic proteins (↓TNF‐α, ↓BAX, ↓Caspase‐3), and upregulates anti‐apoptotic Bcl‐2 expression.

Heat Stress in Quail: Impacts on Health and Productivity, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts physiological homeostasis in quail, inducing oxidative stress, immune dysregulation, and metabolic imbalance, which impair growth, reproduction, product quality, and welfare. Integrating nutritional, environmental, and genetic–epigenetic strategies enhances thermotolerance, sustains productivity, and supports climate‐smart quail ...

Follicle Stimulating Hormone in Cattle Breeding: Fundamentals, Innovations, and Scope

Animal Research and One Health, EarlyView.
FSH is crucial in cattle reproduction, with exogenous administration enhancing breeding and embryo production. Recombinant FSH offers advantages over pituitary‐extracted variants, including fewer injections, reduced stress, and safer production. These innovations improve breeding efficiency, optimize reproductive outcomes, and contribute to sustainable
