Effects of long-term restricted feeding on plasma leptin, hepatic leptin expression and leptin receptor expression in juvenile Atlantic salmon ( Salmo salar L.)

Effects of long-term restricted feeding on plasma leptin, hepatic leptin expression and leptin receptor expression in juvenile Atlantic salmon ( Salmo salar L.)

Highlights ► Feed-restriction increases leptin-a1 gene expression and plasma leptin in Atlantic salmon parr. ► The two leptin genes ( lepa1 and lepa2 ) appear to be differentially regulated. ► Leptin receptor gene expression in the brain is up-regulated during early summer. ► The two leptin genes ar...

Zusammenfassung:Highlights ► Feed-restriction increases leptin-a1 gene expression and plasma leptin in Atlantic salmon parr. ► The two leptin genes ( lepa1 and lepa2 ) appear to be differentially regulated. ► Leptin receptor gene expression in the brain is up-regulated during early summer. ► The two leptin genes are almost exclusively expressed in the liver. ► Leptin receptor is expressed in the brain as well as in various peripheral tissues.
