...Tegan A. Williams; Nicholas J. Bernier ABSTRACT The physiological roles of corticotropin-releasing factor (CRF) have recently been extended to cytoprotection. Here, to determine whether CRF is neuroprotective in fish, the effects of CRF against high environmental ammonia (HEA)-mediated neurogenic...

Exposure to the novel stressor had no effect on POA and interrenal gene expression. In the pituitary, crfr1 , pomc s, 11βhsd2 , gr s...

To evaluate the hypothesis that corticotropin-releasing factor (CRF) could be involved in that response, we have incubated the hypothalamus and hindbrain of rainbow trout at different glucose concentrations in the presence of different concentrations of CRF...
