Igf binding proteins protect undifferentiated spermatogonia in the zebrafish testis against excessive differentiation [PDF]

open access: yes, 2016
Insulin-like growth factor (Igf) binding proteins (Igfbps) modulate the availability of Igfs for their cognate receptors. In zebrafish testes, Igf3 promotes the proliferation and differentiation of type A undifferentiated (Aund) spermatogonia, and igf3 ...

Embryonic Exposure to the Benzotriazole Ultraviolet Stabilizer 2‐(2H‐benzotriazol‐2‐yl)‐4‐methylphenol Decreases Fertility of Adult Zebrafish (Danio rerio)

open access: yesEnvironmental Toxicology and Chemistry, Volume 43, Issue 2, Page 385-397, February 2024.
Abstract Benzotriazole ultraviolet stabilizers (BUVSs) are emerging contaminants of concern. They are added to a variety of products, including building materials, personal care products, paints, and plastics, to prevent degradation caused by ultraviolet (UV) light.

Dietary Effects of Fermented Cottonseed Meal Substituting Fishmeal on the Growth, Biochemical Indexes, Antioxidant Capacity, and Muscle Quality of Juvenile Golden Pompano (Trachinotus ovatus)

open access: yesAquaculture Nutrition, Volume 2024, Issue 1, 2024.
This study investigated the effects of the dietary replacing fishmeal (FM) with fermented cottonseed meal (FCSM) on growth performance, body coloration, serum biochemistry, muscle quality, and liver antioxidant capacity of juvenile golden pompano (Trachinotus ovatus). Fish were fed with five experimental diets (0 (FM), 12.5% (CSM12.5), 25% (CSM25), 50%

Estrogen-induced inhibition of spermatogenesis in zebrafish is largely reversed by androgen [PDF]

open access: yes, 2018
The hormonal regulation of spermatogenesis involves both gonadotropins and steroid hormones. Long-term in vivo exposure of adult zebrafish to estrogen impaired spermatogenesis associated with an androgen insufficiency, possibly induced by inhibiting ...

Comparative Analyses of IGF-Induced Liver Transcriptomes Reveal Genes and Signaling Pathways Associated with Ovarian Growth and Development in Golden Pompano (Trachinotus ovatus)

open access: yesFishes
Recently, China has become a hotspot for farming golden pompano (Trachinotus ovatus), a commercially valuable marine fish. The genetic mechanisms underlying ovarian development, particularly those regulated by insulin-like growth factors (IGFs), remain ...

Influences of water velocity on ovarian maturation and antioxidant capacity in adult grass carp (Ctenopharyngodon idellus)

open access: yesFrontiers in Marine Science
Ecological operation of hydraulic engineering is essential for the conservation of fishery resources. Water velocity is known to affect the spawning of fishes delivering drifting eggs.

Endocrine and paracrine regulation of spermatogonial differentiation in zebrafish (Danio rerio) [PDF]

open access: yes, 2018
Spermatogenesis in fish, as in other vertebrates, is a developmental process triggered by pituitary gonadotropins (Fsh and Lh) that stimulate testicular production of androgens and growth factors, thus making sperm production possible.

Interplay between Fsh, Igf and Wnt signaling in the regulation of spermatogonial development in the zebrafish Danio rerio [PDF]

open access: yes, 2019
Spermatogenesis relies on the activation of a small population of undifferentiated germ cells called spermatogonial stem cells (SSCs). SSCs reside in a specific microenvironment, called “niche”, formed by somatic cells such as Sertoli, Leydig and myoid ...

Shedding new light on early sex determination in zebrafish

open access: yes, 2020
In contrast to established zebrafish gene annotations, the question of sex determination has still not been conclusively clarified for developing zebrafish, Danio rerio, larvae, 28 dpf or earlier. Recent studies indicate polygenic sex determination (PSD),
