Lactate Dehydrogenase (LDH) is an enzyme that catalyzes the conversion of pyruvate, the end product of glycolysis, into lactate (and vice versa) with concomitant interconversion of NADH and NAD+. LDH is comprised of two major subunits, LDH-A and LDH-B, which can assemble into five different isoenzymes (LDH1, LDH2, LDH3, LDH4, and LDH5).

LDH-A is also known as the M subunit as it is predominantly found in skeletal muscle, and LDH-B is also known as the H subunit as it is predominantly found in the heart. LDH-A is a vital metabolic enzyme that is associated with cancer development, invasion, and metastasis. LDH-A is also the key player of the Warburg effect. LDH-A has been reported to correlate with clinicopathologic characteristics and survival outcome of multiple cancers. The inhibition of LDH-A has an anti-proliferative effect on primary breast tumors. LDH-B is a crucial glycolytic enzyme that catalyses conversion of lactate and NAD+ to pyruvate, NADH and H+. LDHB plays an important role in autophagy in cancer cells.
