Key result
Thermal stress induced dynamic responses in the caudal neurosecretory system of olive flounder, with acute hypothermal stress significantly elevating CRH, UI, and UII mRNA levels.
Why the study?
The dynamic expression and secretion patterns of major CNSS hormones (CRH, UI, and UII) and their response to thermal stress had not been studied.

Thermal stress triggers dynamic CNSS hormone responses in flounder; leaves open translational relevance to vertebrate stress physiology.
The caudal neurosecretory system in olive flounder exhibits dynamic hormonal and gene expression responses to thermal stress, indicating its involvement in thermoregulation and adaptation.
Yuan et al. (2020) studied Thermal stress (n=108). Thermal stress (low or high temperature) vs. Normal temperature (18°C) was evaluated on Plasma cortisol, CRH, and UII levels, and gene expression of CRH, UI, and UII in the CNSS. Thermal stress induced dynamic responses in the caudal neurosecretory system of olive flounder, with acute hypothermal stress significantly elevating CRH, UI, and UII mRNA levels.
