Nutritional status modulates plasma leptin, AMPK and TOR activation, and mitochondrial biogenesis: Implications for cell metabolism and growth in skeletal muscle of the fine flounder

Graphical abstract Highlights ► Study showing novel data on fish skeletal muscle growth and metabolism. ► Positive relationship between plasma leptin and AMPK during fasting and refeeding. ► Positive relationship between AMPK and PGC-1a/OXPHOS complexes. ► Negative relationship between AMPK and TOR...
