Cichlasoma dimerus responds to refeeding with a partial compensatory growth associated with an increment of the feed conversion efficiency and a rapid recovery of GH/IGFs axis

Autor: I. Simó, Silvia E. Arranz, Tomás Horacio Delgadin, M. P. Di Yorio, D. I. Pérez Sirkin, Paula Gabriela Vissio

Many fish species display compensatory growth (CG), a phenomenon by which fasted fish grow faster during refeeding. However, most studies use a group-housed fish approach that could be problematic in social fish when interaction between individuals i

RFamide peptides are expressed in the early stages of development in most vertebrates. Gonadotrophin-inhibitory hormone (GnIH) belongs to the RFamide family, and its role in reproduction has been widely studied in adult vertebrates, ranging from fish

Growth hormone, luteinizing hormone, and follicle-stimulating hormone regulation by neuropeptide Y in both sexes of the cichlid fish, Cichlasoma dimerus

Autor: M. P. Di Yorio, P. G. Vissio, Tomás Horacio Delgadin, D. I. Pérez Sirkin

Publikováno v: Fish Physiology and Biochemistry. 41:843-852

Neuropeptide Y (NPY) is considered the most potent orexigenic peptide, increasing before meal time and during fasting. In teleost, most studies on NPY action upon growth hormone (GH) and luteinizing hormone (LH) were conducted in females or group of

Gonadotrophin-Inhibitory Hormone in the Cichlid Fish Cichlasoma dimerus: Structure, Brain Distribution and Differential Effects on the Secretion of Gonadotrophins and Growth Hormone

Autor: Kazuyoshi Tsutsui, T. H. Delgadin, D. I. Pérez Sirkin, A. Shimizu, Gustavo M. Somoza, M. P. Di Yorio, P. G. Vissio

Publikováno v: Journal of neuroendocrinology. 28(5)

The role of gonadotrophin-inhibitory hormone (GnIH) in the inhibition of the reproductive axis has been well-established in birds and mammals. However, its role in other vertebrates, such as the teleost fish, remains controversial. In this context, t

In this study, we investigated the effect of leptin on the ovarian metalloproteinase system in the rat during the ovulatory process. Ovulation was induced in immature rats primed with gonadotropins. In both in vitro and in vivo experiments, we measur

Leptin modulates the expression of its receptors in the hypothalamic-pituitary-ovarian axis in a differential way

Autor: Alicia Graciela Faletti, María Carolina Pustovrh, J P Prestifilippo, M. P. Di Yorio, María Guillermina Bilbao

Publikováno v: The Journal of endocrinology. 198(2)

To investigate the expression of leptin receptors (Ob-R) in the rat hypothalamus–pituitary–ovarian axis, immature rats were treated with eCG/hCG and Ob-R expression was evaluated by western blot analysis. The Ob-R expression increased 24 h after

The aims of this study were to investigate the negative action of leptin on some intraovarian ovulatory mediators during the ovulatory process and to assess whether leptin is able to alter the expression of its ovarian receptors. Immature rats primed
