.... This was associated with upregulated liver gene expression of leptin A1 , leptin A2 , SOCS1 , SOCS2 and SOCS3 , and reduced IGF-I expression. In an in vitro study with liver slices it was shown that recombinant rainbow trout leptin stimulated SOCS1 and SOCS3 expression, but not SOCS2 , IGF-I or genes of enzymes...

... and nuclei numbers and a higher nuclei to fibre ratio (ED18), preceded by increased hindlimb Myf5 (ED5–8), Pax7 (ED5–10), BMP4 (ED6–9) and IGF-I (ED9–10, ED18) mRNAs. In broilers, the same temperature treatment led to reduced gastrocnemius cross-sectional area with fewer fibres and nuclei and an unchanged...

...) and secretory activity (release of progesterone, P 4 , and insulin-like growth factor, IGF-I) in whole ovarian follicles and granulosa cells cultured in conditions of normal temperature (37.5°C) and feeding (with serum), high temperature (41.5°C, with serum) and malnutrition (37.5°C, without serum...

...Neil I. Bower; Xuejun Li; Richard Taylor; Ian A. Johnston SUMMARY In this study we describe the complete coding sequence for insulin-like growth factor I (IGF-I), insulin-like growth factor II (IGF-II), insulin-like growth factor binding protein (IGFBP) 1, 2, 4, 5 and 6 and IGFBP-related protein 1...

... was lower (P <0.004)post-hibernation relative to pre-hibernation and hibernation periods. Insulin-like growth factor I (IGF-I) decreased (P <0.0001) during hibernation relative to pre-hibernation and reached its highest value during remobilization. There was no difference (P =0.64) in 25-OH vitamin D...

... the role of insulin and insulin-like growth factor I (IGF-I) in fish adipose tissue function, we have investigated the presence and the regulation of insulin and IGF-I receptors in adipose tissue of brown trout (Salmo trutta). Receptors for insulin and IGF-I were detected in trout adipose tissue, with IGF...
