Overview

Randomized trial investigates gill tissue damage in Gymnocypris eckloni under acute heat stress, indicating significant physiological impacts.

Key Points

  • This study aims to investigate the impacts of acute heat stress on the gill tissue of Gymnocypris eckloni, focusing on physiological and molecular responses.
  • Conducted histopathological analysis and biochemical assessments of gill tissues.
  • Performed transcriptomic analysis to identify differentially expressed genes (DEGs) in response to heat stress.
  • Analyzed physiological responses related to inflammatory pathways and oxidative stress.
  • Heat stress caused severe gill damage, with lamellar curling, epithelial detachment, and significant apoptosis.
  • Biochemical changes included elevated cortisol, glucose, ATPase activity, and increased MDA content and catalase activity.
  • Transcriptomic analysis identified 2304 DEGs, with upregulated genes enriched in inflammatory and apoptotic pathways.
