Hormonal regulation of antifreeze protein gene expression in winter flounder MUN Library Link: https://link-springer-com.qe2a-proxy.mun.ca/content/pdf/10.1007/BF00004733.pdf PubMed Link: https://pubmed.ncbi.nlm.nih.gov/24221798/ Summary This paper discusses antifreeze proteins (AFP) or glycopeptide antifreeze proteins (AFGP) in teleost fish, and in particular, how these proteins are regulated by environmental conditions stimulating or suppressing growth hormone (GH) in Pseudopleuronectes americanus. These proteins are important since they are distributed throughout the body in the blood plasma and prevent ice crystals from penetrating the epidermis causing trauma. This allows the fish to survive in sub freezing temperatures which occur in their habitat during winter months. The production of these proteins are cyclic and relate to the length of the days, with protein synthesis increasing in fall as days become shorter, since GH is suppres...
