Igf3 activates β-catenin signaling to stimulate spermatogonial differentiation in zebrafish [PDF]
Journal of Endocrinology, 2018 Follicle-stimulating hormone (Fsh) is a major regulator of spermatogenesis, targeting somatic cell functions in the testes. We reported previously that zebrafish Fsh promoted the differentiation of type A undifferentiated spermatogonia (Aund) by stimulating the production of factors that advance germ cell differentiation, such as androgens, insulin ...

Igf3 serves as a mediator of luteinizing hormone in zebrafish ovulation† [PDF]
Biology of Reproduction, 2018 Both oocyte maturation and ovulation is triggered by the luteinizing hormone (LH) surge in vertebrates, but exactly how these processes are regulated by LH remains to be fully elucidated. Previously, we found that Igf3, a fish-specific member of the igf family predominantly expressed in the gonads, could mediate the action of LH on oocyte maturation in

Somatostatin 4 regulates growth and modulates gametogenesis in zebrafish [PDF]
Aquaculture and Fisheries, 2019 Somatostatin (SST) plays important roles in growth and development. In teleost fishes six SST encoding genes (sst1 to sst6) have been identified although few studies have addressed their function.

Cis-regulatory differences in isoform expression associate with life history strategy variation in Atlantic salmon. [PDF]
PLoS Genet, 2020 A major goal in biology is to understand how evolution shapes variation in individual life histories. Genome-wide association studies have been successful in uncovering genome regions linked with traits underlying life history variation in a range of ...

Cloning and Expression Analysis of IGF3 in Turbot (Scophthalmus maximus)
Progress in Fishery SciencesThe insulin-like growth factor (IGF) system plays a key regulatory role in biological processes, such as growth, reproduction, early development, cell differentiation, and proliferation, in fish and other vertebrates.

Impact of germ cell ablation on the activation of the brain-pituitary-gonadal axis in precocious Atlantic salmon (Salmo salar L.) males. [PDF]
Mol Reprod Dev, 2022 Abstract The germ cells are essential for sexual reproduction by giving rise to the gametes, but the importance of germ cells for gonadal somatic functions varies among vertebrates. The RNA‐binding dead end (Dnd) protein is necessary for the specification and migration of primordial germ cells to the future reproductive organs.
