In cancer cells, c-Myc is often elevated, which promotes energy production and biomolecule synthesis [63] by regulating genes for anabolic enzymes such as aspartate transcarbamylase and dihydroorotase (CAD), serine hydroxymethyl transferase (SHMT), fatty acid synthase (FAS), and ornithine decarboxylase (ODC). The gene discussed is CAD; the disease is cancer.
