Overview

Study reveals corticotropin-releasing hormone impacts appetite and growth in largemouth bass, indicating acute heat stress alters their function.

Key Points

  • This research aims to characterize corticotropin-releasing hormone family members and their expression under different conditions in largemouth bass.
  • Identified CRH family members in largemouth bass
  • Analyzed expression profiles in response to feeding
  • Studied effects of acute and chronic heat stress
  • Measured serum cortisol levels and hypothalamic gene expression
  • Five CRH members were identified in largemouth bass
  • CRH gene expression varied significantly with feeding and heat stress
  • Acute heat stress increased serum cortisol and specific gene expression
  • Chronic heat stress affected cortisol levels and gene regulation patterns
