ALDOB (aldolase B; fructose-bisphosphate aldolase B) is a
glycolytic and fructolytic enzyme that cleaves fructose-1-phosphate into
dihydroxyacetone phosphate and glyceraldehyde and also catalyzes reversible
reactions involving fructose-1,6-bisphosphate. ALDOB is highly expressed in
liver, kidney and small intestine and links fructose metabolism with glycolysis,
gluconeogenesis and central carbon metabolism. Its role in cancer is
context-dependent. In colorectal cancer liver metastases,
ALDOB is strongly upregulated and enables metastatic tumour cells to exploit
fructose as a carbon source, supporting glycolysis, biosynthesis and metastatic
growth; ALDOB knockdown reduces liver metastatic growth in experimental models.
Conversely, ALDOB is reduced in some cancers, including gastric cancer, where
restoration of ALDOB has suppressed glycolysis, proliferation and migration.
