... ( Eames et al., 2010 ; Eliason et al., 2010 ; Wood et al., 2010 ). We have investigated transcriptional regulation in the fast myotomal muscle of male zebrafish in response to a single satiating meal delivered at first light. Expression of all 16 genes of the IGF system was investigated by quantitative...

... ). Fig. 4. Influence of temperature on the ultrastructure of myotomal muscle in larval Atlantic herring ( Clupea harengus )( Vieira and Johnston, 1992 ).(A) Camera lucida drawing of a 1-day old larva sectioned immediately posterior to the yolk-sac. (B) Transverse electron micrograph of a 1-day old...

... 2 mRNA expression was restricted to muscle and brain. In developing muscle, Tmyostatin 1 expression was observed in eyed-stage embryos well before hatching, whereas Tmyostatin 2 was expressed only in free-swimming larvae. In myotomal muscle from adult animals, Tmyostatin 1 mRNA accumulation...

... forces from the water. The coupling between both waves depends on the lateral body shape and on the mechanical properties of the tail. During steady swimming, the length of each myotomal muscle fibre varies cyclically. The phase relationship between the strain (muscle length change) cycle and the active...
