Mitochondrial Proteins In Hypertrophy And Atrophy: A Transcript Analysis In Rat Heart

1. Metabolic processes are acutely and chronically regulated in response to changes in the workload of the heart. Acute changes in cardiac work result in activation and inactivation of existing enzymes and in altered fluxes through existing metabolic pathways. Sustained or chronic changes in cardiac work result in both trophic and transcriptional alterations.
