Zebrafish Fshb Antibody / Follicle stimulating hormone beta

Zebrafish Fshb plays a crucial role in the development and maturation of gametes, particularly in promoting folliculogenesis in females and spermatogonial proliferation in males. Its expression and secretion are primarily regulated by gonadotropin-releasing hormone (GnRH) and modulated by feedback from sex steroids and other endocrine factors within the hypothalamic-pituitary-gonadal (HPG) axis. During zebrafish development, fshb expression becomes evident post-embryonically and increases with sexual maturation. Functional studies have shown that Fshb is essential for early-stage follicle development and the onset of puberty, while also contributing to basal steroidogenesis in the gonads. Given the genetic accessibility and transparency of zebrafish, the fshb gene and its protein product are commonly used in reproductive biology, toxicology, and endocrine disruption studies. Zebrafish Fshb shares structural and functional homology with its mammalian counterparts, making it a valuable model for exploring conserved mechanisms of vertebrate reproduction.
