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

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

Orexin and neuropeptide Y: Tissue specific expression and immunoreactivity in the hypothalamus and preoptic area of the cichlid fish Cichlasoma dimerus

Autor: Maximiliano Cánepa, D. I. Pérez Sirkin, P. G. Vissio, Hirohumi Suzuki

Publikováno v: Tissue and Cell. 45:452-459

Neuropeptide Y (NPY) and orexin are neuropeptides involved in the regulation of feeding in vertebrates. In this study we determined the NPY and orexin mRNA tissue expression and their immunoreactivity distribution in both preoptic area and hypothalam

Melanin concentrating hormone (MCH) is involved in the regulation of growth hormone in Cichlasoma dimerus (Cichlidae, Teleostei)

Autor: Maximiliano Cánepa, Mariana Fossati, Luis Fabián Canosa, T. H. Delgadin, Gustavo M. Somoza, D. I. Pérez Sirkin, Juan I. Fernandino, P. G. Vissio

Growth hormone (GH) is the main pituitary hormone involved in somatic growth. In fish, the neuroendocrine control of GH is multifactorial due to the interaction of multiple inhibitors and stimulators. Melanin-concentrating hormone (MCH) is a cyclic p

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
