the somatic Leydig cells and Sertoli cells; and germ cells like spermatogonia, pachytene spermatocytes and round spermatids ( Pelt et al . 1999 ). In the efferent ductules, small tubules transporting sperm from the rete testis to the caput epididymis

Niemann-Pick C1 cholesterol transporter ( Carstea et al . 1997 , Loftus et al . 1997 ), which has led to the suggestion that, in an Hh binding-modulated fashion, Ptch might transport small molecule regulators of Smo activity. Adding support to this idea

Introduction Cortisol is the major corticosteroid in fish, and its effects on transcellular ion transport are well documented (see review by McCormick (2001) ). Increasing evidence suggests that cortisol may also regulate paracellular permeability

( Narayan & Towle 1985 , Serrano-Nascimento et al . 2010 ). Segal et al . (1977) demonstrated that T 3 provokes a rapid increase in 2-deoxyglucose uptake in cultured chick embryo heart cells. This effect was evident within minutes of T 3 addition and

medium contained 0.5% BSA, 2 mM caffeine, 1 nM ANP and/or 1 μM KT5823. Culture medium for embryo development was North Carolina State University (NCSU) 23 ( Petters & Wells 1993 ) containing 0.4% BSA, 75 μg/ml potassium penicillin G and 50 μg

corpus luteum increases after ovulation. However, if no fertilization or embryo implantation occurs, the corpus luteum regresses and PPARγ expression decreases ( Lohrke et al. 1998 , Viergutz et al. 2000 ) (Fig. 2 ). In chickens, a similar

neuronal BHBA uptake: diffusion and carrier-mediated transport systems ( Tildon & Roeder 1988 ). Members of the H + -coupled MCT (SLC16A1) family (MCT1, MCT2 (SLC16A7) and MCT4; Morris & Felmlee 2008 ) and members of the solute carrier (SLC) group, the

hyperglycemia-induced overproduction of superoxide (O 2 ·− ) by the mitochondrial electron transport chain ( Brownlee 2001 ). Thus, it was proposed that increased glycolytic flux leads to increased hyperglycemia-derived electron donors from the tricarboxylic
