Feeding increases MyoD and PCNA expression in myogenic progenitor cells of Notothenia coviiceps
Oxygen consumption and ammonia excretion of the Antarctic fish Notothenia coriiceps (18.4 cm L F ) increased respectively two and fourfold above fasting levels 24 h after feeding with a single meal of shrimps (5.5 to 7.5% of body mass), and remained elevated for 120 h. In fasted fish, c‐met positive...
