Open AccessInsulin-like 3 affects zebrafish spermatogenic cells directly and via Sertoli cells
Pituitary hormones can use local signaling molecules to regulate target tissue functions. In adult zebrafish testes, follicle-stimulating hormone (Fsh) strongly increases the production of insulin-like 3 (Insl...

Open AccessDevelopment of supermale and all-male Atlantic salmon to research the vgll3 allele - puberty link
Farmed Atlantic salmon are one of the most economically significant global aquaculture products. Early sexual maturation of farmed males represents a significant challenge to this industry and has been linked ...

Open AccessRescue of germ cells in dnd crispant embryos opens the possibility to produce inherited sterility in Atlantic salmon
Genetic introgression of escaped farmed Atlantic salmon (Salmo salar) into wild populations is a major environmental concern for the salmon aquaculture industry. Using sterile fish in commercial aquaculture opera...

Open AccessCorrection to: Entry into puberty is reflected in changes in hormone production but not in testicular receptor expression in Atlantic salmon (Salmo salar)
Following publication of the original article [1], the authors would like to apologize for an error in Fig. 5e, the correct graph is presented below and shows the significant increase in pituitary mRNA levels of

Open AccessEntry into puberty is reflected in changes in hormone production but not in testicular receptor expression in Atlantic salmon (Salmo salar)
Puberty in male Atlantic salmon in aquaculture can start as early as after the first winter in seawater, stunts growth and entails welfare problems due to the maturation-associated loss of osmoregulation capac...

Open AccessThe initiation of puberty in Atlantic salmon brings about large changes in testicular gene expression that are modulated by the energy status
When puberty starts before males reach harvest size, animal welfare and sustainability issues occur in Atlantic salmon (Salmo salar) aquaculture. Hallmarks of male puberty are an increased proliferation activity ...

Open AccessVgll3 and the Hippo pathway are regulated in Sertoli cells upon entry and during puberty in Atlantic salmon testis
Vgll3 is linked to age at maturity in Atlantic salmon (Salmo salar). However, the molecular mechanisms involving Vgll3 in controlling timing of puberty as well as relevant tissue and cell types are currently unkn...

Open AccessSex steroid production associated with puberty is absent in germ cell-free salmon
In all vertebrates studied so far, germ cells are not required for pubertal maturation of the gonadal steroidogenic system, subsequent development of secondary sex characteristics and reproductive behavior. To...

Open AccessDnd knockout ablates germ cells and demonstrates germ cell independent sex differentiation in Atlantic salmon
Introgression of farmed salmon escapees into wild stocks is a major threat to the genetic integrity of wild populations. Using germ cell-free fish in aquaculture may mitigate this problem. Our study investigat...

Effect of in vivo chronic exposure to clotrimazole on zebrafish testis function
Clotrimazole is an azole fungicide used as a human pharmaceutical that is known to inhibit cytochrome P450 (CYP) enzymatic activities, including several steroidogenic CYP. In a previous report, we showed that ...

Open AccessSex differentiation in Atlantic cod (Gadus morhua L.): morphological and gene expression studies
In differentiated gonochoristic species, a bipotential gonad develops into an ovary or testis during sex differentiation. Knowledge about this process is necessary to improve methods for masculinizing genetica...

Open AccessCompletion of meiosis in male zebrafish (Danio rerio) despite lack of DNA mismatch repair gene mlh1
Mlh1 is a member of DNA mismatch repair (MMR) machinery and is also essential for the stabilization of crossovers during the first meiotic division. Recently, we have shown that zebrafish mlh1 mutant males are co...

Social stimulation, nuptial colouration, androgens and immunocompetence in a sexual dimorphic cichlid fish
The nature of the costs maintaining honesty of sexual signalling in inter- and intrasexual interactions remains a contentious issue. For carotenoid-based colour ornaments, it has been hypothesized that the hon...

Spermatogenesis and its endocrine regulation
Three major phases compose spermatogenesis: mitotic proliferation of spermatogonia, meiosis of spermatocytes, and spermiogenesis, the restructuring of spermatids into flagellated spermatozoa. The process is fu...

Specific binding of 11-ketotestosterone in an androgen target organ, the kidney of the male three-spined stickleback,Gasterosteus aculeatus
The kidney of male three-spined stickleback,Gasterosteus aculeatus, hypertrophies during the breeding season and produces a “glue” which is used in the building of the nest. This hypertrophy is androgen dependent...
