BACKGROUND: Bisphenol A (BPA), used in the manufacture of plastics, is ubiquitously distributed in the aquatic environment. However, the effect of maternal transfer of these xenobiotics on embryonic development and growth is poorly understood in fish

Previous studies show that changes in estrogen (ER) and glucocorticoid receptor (GR) function in rainbow trout (Oncorhynchus mykiss) oocytes modulate the growth performance phenotype of embryo and juvenile progeny; the present study was undertaken to

Epigenetics is the study of changes in gene expression patterns that occur without any modification of the underlying nucleotide sequence of the DNA. Modifications of the so-called epigenome include complex transient or permanent chemical changes of

The ontogeny of lysozyme activity, intelectin, TLR-5M and TLR-5S gene expression and intelectin localization was examined in rainbow trout (Oncorhynchus mykiss) reared from oocytes immersed for 3h prior to fertilization in either ovarian fluid alone

The purpose of this overview is to re-examine the postulated direct and indirect actions of glucocorticoids on ovarian function in teleosts. The re-examination is undertaken in light of recent advances in the understanding of the stress response itse

Anti-thyroxine (T4) immunostaining in the endostyle and thyroid tissue during metamorphosis of sea lamprey Petromyzon marinus suggested that T4 synthesis occurs on the luminal surface of the apical membrane of selected cells of the endostyle, and tha

The purpose of the study was to investigate whether dietary ration or diet composition influence the relationship between plasma growth hormone (GH) and insulin-like growth factor-1 (IGF-1) in Arctic charr (Salvelinus alpinus L.). The pattern of chan

Real time RT-PCR was used to measure the changes in the rates of synthesis of mRNA encoding for growth hormone-1 (GH1) and -2 (GH2) and insulin-like growth factor-1 (IGF-1) and -2 (IGF-2), and whole embryo GH content was measured in early stage rainb

The three dimensional morphology of the thyroid tissue in juvenile rainbow trout Oncorhynchus mykiss was determined using serial transverse and longitudinal sections of lower jaws stained with haematoxylin and eosin. The thyroid tissue comprised inte

The accumulation of mRNA encoding for hepatic and intestinal T3-receptor (TR) and body and liver masses were measured in fed and 3-week fasted juvenile and swim up stage rainbow trout embryos. Plasma and total body thyroid hormone (TH) levels were me
