Prolactin and growth hormone in fish osmoregulation

T Sakamoto, SD McCormick - General and comparative endocrinology, 2006 - Elsevier
Prolactin is an important regulator of multiple biological functions in vertebrates, and has
been viewed as essential to ion uptake as well as reduction in ion and water permeability of …

Osmoregulatory actions of growth hormone and its mode of action in salmonids: a review

T Sakamoto, SD McCormick, T Hirano - Fish Physiology and Biochemistry, 1993 - Springer
Osmoregulatory actions of growth hormone (GH) and its mode of action in salmonids are
reviewed. We present evidence suggesting that insulin-like growth factor I (IGF-I) mediates …

[HTML][HTML] Evolutionary differentiation of androgen receptor is responsible for sexual characteristic development in a teleost fish

…, M Yasugi, Y Katayama, H Sakamoto… - Nature …, 2023 - nature.com
Teleost fishes exhibit complex sexual characteristics in response to androgens, such as fin
enlargement and courtship display. However, the molecular mechanisms underlying their …

Osmoregulatory actions of growth hormone and prolactin in an advanced teleost

T Sakamoto, BS Shepherd, SS Madsen… - General and …, 1997 - Elsevier
To date, growth hormone (GH) is known to contribute to seawater adaptation only in salmonid
fishes (primitive Euteleostei). Accordingly, the effects of homologous GH and two forms of …

…, J Hiroi, H Takahashi, T Sakamoto - American Journal of …, 2014 - journals.physiology.org
Teleost fishes are the major group of ray-finned fishes and represent more than one-half of
the total number of vertebrate species. They have experienced in their evolution an additional …

Expression of insulin-like growth factor I gene in osmoregulatory organs during seawater adaptation of the salmonid fish: possible mode of osmoregulatory action of …

The role of 'mineralocorticoids' in teleost fish: relative importance of glucocorticoid signaling in the osmoregulation and 'central'actions of mineralocorticoid receptor

H Takahashi, T Sakamoto - General and comparative endocrinology, 2013 - Elsevier
It has long been held that cortisol, a glucocorticoid in many vertebrates, performs glucocorticoid
and mineralocorticoid actions in the teleost fish since it lacks aldosterone. However, in …
