Acute physiological stress down-regulates mRNA expressions of growth-related genes in coho salmon.
Growth and development in fish are regulated to a major extent by growth-related factors, such as liver-derived insulin-like growth factor (IGF) -1 in response to pituitary-secreted growth hormone (GH) binding to the GH receptor (GHR).Here, we report on the changes in the expressions of gh, ghr, and igf1 genes and the circulating levels of GH and I
