Exploration of Synergistic Regulation Mechanisms of Cerebral Ganglion and Muscle in <i>Eriocheir sinensis</i> Activated in Response to Alkalinity Stress

Abstract

The cerebral ganglion and muscle are important regulatory tissues in Eriocheir sinensis. Therefore, it is of great significance to explore their synergistic roles in this organism’s anti-stress response. In this study, proteomics, metabolomics, and combination analyses of the cerebral ganglion and muscle of E. sinensis under alkalinity stress were performed. The cerebral ganglion and muscle played a significant synergistic regulatory role in alkalinity adaptation. The key regulatory pathways involved were amino acid metabolism, energy metabolism, signal transduction, and the organismal system. They also played a modulatory role in the TCA cycle, nerve signal transduction, immune response, homeostasis maintenance, and ion channel function. In conclusion, the present study provides a theoretical reference for further research on the mechanisms regulating the growth and development of E. sinensis in saline–alkaline environments. In addition, it provides theoretical guidelines for promoting the vigorous development of the E. sinensis breeding industry in saline–alkaline environments in the future.
