Rewiring urea cycle metabolism in cancer to support anabolism

Abstract

Cancer cells reprogramme metabolism to maximize the use of nitrogen and carbon for the anabolic synthesis of macromolecules that are required during tumour proliferation and growth. To achieve this aim, one strategy is to reduce catabolism and nitrogen disposal. The urea cycle (UC) in the liver is the main metabolic pathway to convert excess nitrogen into disposable urea. Outside the liver, UC enzymes are differentially expressed, enabling the use of nitrogen for the synthesis of UC intermediates that are required to accommodate cellular needs. Interestingly, the expression of UC enzymes is altered in cancer, revealing a revolutionary mechanism to maximize nitrogen incorporation into biomass. In this Review, we discuss the metabolic benefits underlying UC deregulation in cancer and the relevance of these alterations for cancer diagnosis and therapy.

Glossary

Anaplerosis

The process of replenishing depleted metabolic cycle or pathway intermediates.

Aspartate transcarbamylase

An enzyme that catalyses the formation of carbamoyl aspartic acid and inorganic phosphate from aspartate and carbamoyl phosphate (CP), which is the first step in pyrimidine synthesis.

Dihydroorotase

An enzyme that catalyses the formation of 4,5-dihydroorotic acid from carbamoyl aspartic acid during pyrimidine synthesis.

Pyrimidine

An aromatic ring composed of two nitrogen atoms and four carbon atoms, from which derive the three nitrogenous bases thymine, uracil and cytosine.

Compartmentalization

The restriction of a cellular component or process within a defined cellular compartment, such as the cytosol or a specific organelle.

Pyruvate carboxylase

A mitochondrial enzyme that catalyses the formation of oxaloacetate from pyruvate. The reaction is irreversible. Oxaloacetate can replenish the tricarboxylic acid cycle or be used for gluconeogenesis.

Fumarate hydratase

(FH). An enzyme that catalyses the hydration of fumarate to malate in the tricarboxylic acid cycle (mitochondrial isoform) or as a reaction contributing to fumarate and amino acid metabolism in the cytosol (cytosolic isoform). The reaction is reversible.
