The NMDA receptor activation by d-serine and glycine is controlled by an astrocytic Phgdh-dependent serine shuttle [PDF]
Astrocytes express the 3-phosphoglycerate dehydrogenase (Phgdh) enzyme required for the synthesis of L-serine from glucose. Astrocytic L-serine was proposed to regulate NMDAR activity by shuttling to neurons to sustain D-serine production, but this ...

PHGDH amplification and altered glucose metabolism in human melanoma
Pigment Cell & Melanoma Research, 2011SummaryThe metabolic requirements of cancer cells differ from that of their normal counterparts. To support their proliferation, cancer cells switch to a fermentative metabolism that is thought to support biomass production. Instances where metabolic enzymes promote tumorigenesis remain rare.

Increased Expression of PHGDH Under High-Selenium Stress In Vivo
Biological Trace Element ResearchThe purpose of this study is to explore the glycolytic remodeling under high-selenium (Se) stress. Three groups of male C57BL/6J mice were fed on diets with different Se contents (0.03, 0.15, and 0.30 mg Se/kg). Glucose tolerance test (GTT) and insulin tolerance test (ITT) were measured at the third month. Mice were killed at the fourth month.

Phosphoglycerate dehydrogenase (PHGDH) deficiency without epilepsy mimicking primary microcephaly
American Journal of Medical Genetics Part A, 2017Phosphoglycerate dehydrogenase (PHGDH) deficiency (OMIM 256520) is a rare autosomal recessive disorder of serine synthesis, with mostly severe congenital microcephaly, caused by mutations in the PHGDH gene. Fourteen patients reported to date show severe, early onset, drug resistant epilepsy.

PHGDH alleviates DKD by regulating YB1/SLC7A11-mediated ferroptosis in podocytes
Translational ResearchDiabetic kidney disease (DKD) is a main cause of end-stage renal disorder, yet its pathogenesis is still incompletely understood. Ferroptosis has been implicated in DKD progression; however, its regulatory mechanisms remain unclear. Phosphoglycerate dehydrogenase (PHGDH), a key enzyme in serine biosynthesis, has been minimally studied in DKD ...
