ABSTRACT The potential benefits of enhancing the capacity for carbohydrate utilization in farmed fish, particularly species with pronounced intolerance, are significant from a number perspectives. In recent decades, multitude research initiatives have focused on elucidating factors that influence as well biological limitations constrain this process. Despite substantial progress achieved thus far, dearth clarity persists regarding associated tolerance among various species. Evidence suggests that, mammals, pancreatic islet tissues teleosts act regulatory valve glucose assimilation and metabolism. However, precise intricacies remain to be fully elucidated subject ongoing endeavors fish objective review is provide comprehensive evaluation extant gaps domain endocrinology, aim identifying potentially impede Furthermore, it incorporates advancements biology physiological functions homeostasis zebrafish model mammalian animals more overview future directions fish. addition, we present prospective avenues inquiry concomitant challenges achieve profound comprehension fundamental mechanisms precipitate intolerance This expected benefit researchers specializing study metabolism

Smoltification is stressful for salmonids, and cortisol one of the central endocrine regulators seawater adaptation. It has been established that plays both mineralocorticoid glucocorticoid functions by MR GR, respectively, since aldosterone hormone absent. Recently, investigations have proposed 11-deoxycorticosterone (DOC) precursor might support effects, but this mechanism remains unclear. Hence, we assessed early effects DOC on rainbow trout pre-smolts, key smoltification stage, via metabolic transcriptomic approaches. Thirty-six juveniles (~120 g) were treated 3 h with (1 mg/kg) and/or (eplerenone) or (mifepristone) receptor antagonists (n = 6 each group). decreased plasma glucose pyruvate increased phosphate liver glycogen. also downregulated carbohydrate metabolism-related genes in liver. Finally, gill RNA-seq analysis presented 1660 differentially expressed transcripts versus vehicle, 1022 eplerenone + 3324 mifepristone DOC. The enrichment mainly revealed upregulation ion transmembrane transport metabolism downregulation stress innate immune responses. This suggests a significant role osmoregulation pre-smolts through receptors. could contribute to improving animal welfare monitoring during featuring novel potential biomarkers.
