Stress is an event that most animals experience and that induces a number of responses
involving all three regulatory systems, neural, endocrine and immune. When the stressor is …

Previous reviews of stress, and the stress hormone cortisol, in fish have focussed on
physiology, due to interest in impacts on aquaculture production. Here, we discuss cortisol in …

Steroid hormones are involved in the regulation of a variety of processes like embryonic
development, sex differentiation, metabolism, immune responses, circadian rhythms, stress …

Transcription and translation require a high concentration of potassium across the entire tree
of life. The conservation of a high intracellular potassium was an absolute requirement for …

In the last years, the aquaculture crops have experienced an explosive and intensive
growth, because of the high demand for protein. This growth has increased fish susceptibility …

The teleost-specific whole genome duplication event 350 million years ago resulted in a
variety of duplicated genes that exist in fish today. In this review, we examine whether …

Combinations of stressors occur regularly throughout an animal's life, especially in
agriculture and aquaculture settings. If an animal fails to acclimate to these stressors, stress …

The study of the causes and mechanisms underlying psychiatric disorders requires the use
of non-human models for the test of scientific hypotheses as well as for use in pre-clinical …

The main objectives of this study were to investigate the dynamics of the cortisol stress
response and the underlying molecular regulation in adult zebrafish exposed to acute and …

Reproduction in vertebrates is controlled by the Hypothalamus–Pituitary–Gonad axis and
the main hormone actions have been extensively described. Still, despite the scattered …
