Expression profiles of the RNAs encoding enzymes in glycolysis/gluconeogenesis pathway. The blue arrows point to glucose-6-phosphate isomerase [EC: 5.3.19]. Boxes colored in red represent down-regulated genes encoding that enzyme. Boxes colored in green represent up-regulated genes. Boxes colored in yellow represent multiple genes encode the enzyme and some of those different gene copies are up-regulated, while others are down-regulated.
