“…Vanadium insulinmimetic properties have been associated to the activity of tyrosine phosphatases and consequent activation of tyrosine kinase receptors, including the insulin receptor (Goldwaser et al 2000;Shechter et al 1995;Shisheva and Shechter 1993). In vertebrates, a major process regulated by insulin (and insulin-like growth factor 1) is linear bone growth (McCarthy et al 2000;Moriyama et al 2000). Vanadate was also shown to exhibit strong metabolic and mitogenic effects, as demonstrated by in vitro studies using mammalian bone-derived cell lines (and also using rat calvaria and chondrocyte primary cultures) (Canalis 1985a;Kato et al 1987;Lau et al 1988).…”

Vanadium, a trace metal known to accumulate in bone and to mimic insulin, has been shown to regulate mammalian bone formation using in vitro and in vivo systems. In the present work, short-and long-term effects of metavanadate (containing monomeric, dimeric, tetrameric and pentameric vanadate species) and decavanadate (containing decameric vanadate species) solutions on the mineralization of a fish bone-derived cell line (VSa13) were studied and compared to that of insulin. After 2 h of incubation with vanadate (10 μM in monomeric vanadate), metavanadate exhibited higher accumulation rates than decavanadate (6.85±0.40 versus 3.95± 0.10 μg V/g of protein, respectively) in fish VSa13 cells and was also shown to be less toxic when applied for short periods. In longer treatments with both metavanadate and decavanadate solutions, similar effects were promoted: stimulation of cell proliferation and strong impairment (75%) of extracellular matrix (ECM) mineralization. The effect of both vanadate solutions (5 μM in monomeric vanadate), on ECM mineralization was increased in the presence of insulin (10 nM). It is concluded that chronic treatment with both vanadate solutions stimulated fish VSa13 cells proliferation and prevented ECM mineralization. Newly developed VSa13 fish cells appeared to be appropriate in the characterization of vanadate effects on vertebrate bone formation, representing a good alternative to mammalian systems.

“…The antiserum has already been shown to be highly specific for different fish species IGF-I (Dyer et al, 2004). Moreover, the amino acid sequence of E. sea bass IGF-I [GenBank accession number: AAV91771] is 92-94% identical to that of barramundi (Kinhult, 1996, cited by Moriyama et al, 2000;Vega-Rubin de Celis et al, 2004) confirming the high cross-reactivity between E. sea bass IGF-I and barramundi antiserum. Compared with other RIAs (Dyer et al, 2004), the assay showed great sensitivity to and specificity for E. sea bass IGF-I.…”

The aim of this study was to investigate the effects of feeding frequency on post-prandial pattern of circulating glucose, insulin and IGF-I (insulin-like growth factor-I) in European sea bass (D. labrax). Fish (average body weight 72.1 ± 2 g) were randomly allocated in 12 tanks, reared in a closed thermo regulated recirculating system and fed a commercial diet at a fixed ration (1.5% body weight) for 7 weeks. Six fish groups were fed the ration in one meal a day (08: 30 am), while six fish groups were offered the same ration in two daily meals (08: 30 am and 04: 30 pm) according to a complete random design. Plasma insulin mean level was affected by the splitting up of the ration (14.4 vs 15.2 ng/ml, P<0.05, one meal and two meals/day, respectively) and showed a bimodal profile depending on the meal administration. The level of circulating glucose was slightly affected by feeding pattern with an increase of glycaemia after each meal. The daily pattern of plasma IGF-I did not appear related to meal administration. Results show that post prandial plasma glucose, insulin and IGF-I are differently affected by the meal administration pattern in sea bass due to their physiological role in maintaining the internal homeostasis.

“…In Japanese eel (Anguilla japonica), insulin-like growth factor-II (IGF-II) cDNAs were cloned and their mRNA expression was examined in several tissues. Two eel IGF-II cDNAs, eIGF-II-1 and eIGF-II-2, were cloned from the liver [34] [35].…”

Growth in vertebrates is a complex interaction involving the development of cells, tissues and organs. Hormones regulating growth during maturation are involved mainly in the interaction between the somatic axis and the reproduction of brain-pituitary axes. Based on the results of hormone and gene transcriptions, the secretion and treatment controlling both the somatic axis and the gonadotropic axis were affected, directly or indirectly, by the environment parameter through hormones that were studied in my laboratory. A model was proposed for sex differentiation and gonadal development correlating to the growth of European eel (Anguilla anguilla). A high growth variation is affected by the environment. At a low density of eels, the gonadotropin-releasing hormone (GnRH) affected the secretion follicle stimulation hormone (FSH) in the pituitary, steroidogenesis and aromatase (CYP19) synthesis, and the 17β-estradiol (E2) from 11-ketotestosterone (Kt-11) causing ovary development. The ovary secretion E2 affecting the adenylate cyclase-activating polypeptide (PACAP), growth hormone (GH) and the insulin-like growth factor (IGF) stimulated rapid growth in females. On the other hand, a high density of eels caused the pituitary gland to secrete FSH at a lower level, and CYP19 was not synthesized in the gonads. The secretion of Kt-11 affected differentiation to testis, which inhibits the somatic axis in reducing growth rate.
