Background: PHGDH

Phosphoglycerate dehydrogenase (PHGDH) catalyzes the oxidation of 3-phospho-D-glycerate to 3-phosphooxypyruvate, which is the first step of the L-serine biosynthesis pathway. Human PHGDH is a Type I NADH-dependent enzyme that forms an active oligomer where each monomer is composed of 4 domains: a substrate-binding domain, a nucleotide-binding domain, and two regulatory domains: ASB (allosteric substrate binding) and ACT (Aspartate kinase, Chorismate mutase, and Tyr A)(1). Serine biosynthesis by PHGDH is the sole source of serine biosynthesis in mammals (2) and conditional knockout confirmed L-serine synthesis by PHGDH is the source of D-serine in the brain (3). PHGDH null mice are embryonic lethal (4) and mutations that lead to PHGDH deficiency have been reported in infantile, juvenile and adult onset phenotypes (5, 6). PHGDH is also suggested to play a role in several cancers including breast (7), cervical (8), melanoma (9), colon (10), pancreatic (11), liver (12), and kidney (13) through increased PHGDH expression and enhanced tumor cell proliferation. Levels of PHGDH correlate with patient survival and may be used as a prognostic factor (14). A mutation resulting in inactive PHGDH (15), cell line knockdown (8, 11), and treatment with enzymatic inhibitors in cancer cells (13) result in decreased proliferation. Given the correlation between high PHGDH and cancer and the results from indirect inhibition of PHGDH activity, PHGDH is a pharmaceutical target for cancer therapy (16-18).
