Molecular characterization of sea bass gonadotropin subunits (α, FSHβ, and LHβ) and their expression during the reproductive cycle

Seasonal changes in gonadal expression of gonadotropin receptors, steroidogenic acute regulatory protein and steroidogenic enzymes in the European sea bass

“…It is then difficult the extrapolation of salmonid findings to 86 sea bass (or other fish with a non-synchronous type of gonadal development). Contrary to 87 what was described for salmonids (reviewed in Swanson et al, 2003), the expression of the 88 gonadotropin subunits during the reproductive cycle of male sea bass shows overlapping 89 profiles, suggesting that both hormones could be involved in the control of all stages of 90 gonadal development (Mateos et al, 2003). 91 Recently, we have described the molecular characterization of sea bass gonadotropin 92 receptors (Rocha et al, 2007a).…”

Molecular characterization of Chinese sturgeon gonadotropins and cellular distribution in pituitaries of mature and immature individuals

“…Our results suggested that the expression pattern of Chinese sturgeon LH␤ might be similar to that observed in salmonids. In teleosts, the duality of FSH␤ and LH␤ was first revealed by Kawauchi et al (1989) and has been demonstrated in a number of species (Koide et al, 1993;Okada et al, 1994;Hassin et al, 1995;Elizur et al, 1996;García-Hernández et al, 1997;Kagawa et al, 1998;Calman et al, 2001;Mateos et al, 2003;Li et al, 2005;Cerdà et al, 2008). However, it is still unclear whether the FSH␤ and LH␤ are synthesized in the same cells as it occurs in tetrapods (Saito et al, 2002).…”

Examination of the Ability of Gonadal Sex Change in Primary Males of the Diandric Wrasses Halichoeres poecilopterus and Halichoeres tenuispinis: Estrogen Implantation Experiments

“…In well-studied salmonids, FSH plays a significant role in puberty and gametogenesis, whereas LH is primarily involved in final maturation of the gametes in both sexes [16][17][18]. However, variations in the expression profiles and potential roles of GTHs were reported in other teleost species [19][20][21][22]. In protogynous wrasse, sexual dimorphic expression patterns of fshb and lhb transcripts were observed during the spawning season [23].…”
