Fig. 4

Schematic representation of the role of DEGs assigned to energetic metabolism and their regulation in newly hatched ducklings from the R group. The main metabolic pathways impacted by the maternal methionine deficiency are noted (glycolysis, electron transport, de novo lipogenesis, etc.). Up-regulated and down-regulated DEGs in ducklings issued from dams receiving Met-restricted diet are in red and green, respectively. The genes [BMF] and [PPARA] tended to be significant for the diet effect and were added to the Figure but kept in brackets. PPARA promotes fatty acid oxidation whereas PPARG favors de novo lipogenesis (dashes of brown color). PRKAA1 drives fatty acid oxidation (dashes of brown color) and decreases de novo lipogenesis (dashes of grey color). PPARGC1B regulates mitochondrial energy transfers (dashes of brown color)
