Piscirickettsia salmonis is one of the most significant pathogens affecting salmon farming. Besides liver, head kidney and spleen, skeletal muscle has shown transcriptional immune responses to these bacteria, but the contribution of non-coding RNAs remains poorly understood. This study investigates the role of long non-coding RNAs (lncRNAs) in the immune response of rainbow trout skeletal muscle and primary myotube cultures in...

Glucocorticoids are key regulators of vertebrate physiology, orchestrating metabolic, immune, and developmental processes that enable adaptation to stress. In teleosts, cortisol is the primary glucocorticoid, acting through classical genomic pathways and rapid non-genomic mechanisms. Although genomic signaling has been widely characterized, non-genomic actions remain poorly understood in skeletal muscle, a tissue of both biolo...

Red cusk‐eel ( Genypterus chilensis ) is a native species with potential for Chilean aquaculture diversification. However, no information exists on the effects of temperature on oxidative stress and eggs quality markers in post‐ovulatory eggs and ovary of this species. We determine that high and low temperature generate oxidative damage on post‐ovulatory eggs, with no effect on ovary. Temperature induces thermal stress markers...
