Teleosts lack a hypophyseal portal system and hence neurohormones are carried by nerve
fibers from the preoptic region to the pituitary. The various cell types in the teleost pituitary …

In humans, as in the other mammals, the neuroendocrine control of reproduction is ensured
by the brain-pituitary gonadotropic axis. Multiple internal and environmental cues are …

The KISS1 gene encodes the kisspeptin neuropeptide, which activates the KISS1 receptor
(KISS1R; G protein-coupled receptor 54; GPR54) and participates in neuroendocrine …

Gonadotropins, follicle-stimulating hormone (FSH), and luteinizing hormone (LH) play
critical roles in vertebrate reproduction. In the present study, we cloned and characterized …

In this study, we aimed to identify the toxic effects of chlorpyrifos exposure on the tissues of
common carp. For this purpose, we evaluated histopathological changes in the brain, gills …

The pivotal role of gonadotropin signaling in regulating gonadal development and functions
has attracted much research attention in the past 2 decades. However, the precise …

The ongoing of global warming trend has led to an increase in temperature of several water
bodies. Reproduction in fish, compared with other physiological processes, only occurs in a …

Ectodermal placodes comprise the adenohypophyseal, olfactory, lens, profundal, trigeminal,
otic, lateral line, and epibranchial placodes. The first part of this review presents a brief …

In the zebrafish model, the ontogenic expression profiles of all pituitary hormones have been
reported except gonadotropins, partly because they are not supposed to be expressed in the …

In fish, luteinizing hormone (LH) stimulates processes leading to final oocyte maturation and
ovulation in females, and spermiation in males. The hormone is a heterodimeric …
