Phosphoserine aminotransferase 1 promotes serine synthesis pathway and cardiac repair after myocardial infarction. [PDF]
Background and Purpose: The permanent loss of cardiomyocytes (CMs) following myocardial infarction (MI), coupled with the heart's limited regenerative capacity, often leads to heart failure. Phosphoserine aminotransferase 1 (PSAT1) is a protein highly expressed in the embryonic mouse heart but markedly downregulated after birth. Despite its presence in

Cancer-associated Fibroblast-like Cells Promote Osteosarcoma Metastasis by Upregulation of Phosphoserine Aminotransferase 1 and Activation of the mTOR/S6K Pathway. [PDF]
Metastasis remains a major obstacle limiting the survival of patients with osteosarcoma (OS). Cross-talk between cancer-associated fibroblasts (CAFs) and OS cells has been found to facilitate metastasis, although the effects of CAFs on OS cell metabolism are poorly understood.

L-serine biosynthesis in the human central nervous system: structure and function of phosphoserine aminotransferase [PDF]
Organisms from all kingdoms of life synthesize L-serine (L-Ser) from 3-phosphoglycerate through the phosphorylated pathway, a three-step diversion of glycolysis.

ATF3 promotes the serine synthesis pathway and tumor growth under dietary serine restriction
Summary: The serine synthesis pathway (SSP) involving metabolic enzymes phosphoglycerate dehydrogenase (PHGDH), phosphoserine aminotransferase 1 (PSAT1), and phosphoserine phosphatase (PSPH) drives intracellular serine biosynthesis and is indispensable ...

Aryloxy Triester Phosphoramidates as Phosphoserine Biocleavable Masking Motifs [PDF]
Many cellular protein-protein interactions (PPIs) are mediated by phosphoserine. The specific targeting of these PPIs by phosphoserine-containing small molecules has been scarce due to the dephosphorylation of phosphoserine and its charged nature at ...

Hepatic Phosphoserine Aminotransferase 1 Regulates Insulin Sensitivity in Mice via Tribbles Homolog 3 [PDF]
Phosphoserine aminotransferase 1 (PSAT1) is an enzyme participating in serine synthesis. A role of PSAT1 in the regulation of insulin sensitivity, however, is unknown. In this study, we showed that hepatic PSAT1 expression and liver serine levels are reduced in genetically engineered leptin receptor–deficient (db/db) mice and high-fat diet (HFD ...

Investigation Of Phosphoserine Aminotransferase 1 And Its Role In Breast Cancer Progression
Metastasis and endocrine resistance are two factors that complicate therapeutic intervention in breast cancer patients and lead to poorer overall survival. Metastasis is known to be responsible for 90% of cancer related deaths, and is especially prevalent in triple negative breast cancer (TNBC); while endocrine resistance can ...
