Structural Analysis of Phosphoserine Aminotransferase (Isoform 1) From Arabidopsis thaliana– the Enzyme Involved in the Phosphorylated Pathway of Serine Biosynthesis [PDF]

Frontiers in Plant Science, 2018
Phosphoserine aminotransferase (PSAT) is a pyridoxal 5′-phosphate (PLP)-dependent enzyme that catalyzes the conversion of 3-phosphohydroxypyruvate (3-PHP) to 3-phosphoserine (PSer) in an L-glutamate (Glu)-linked reversible transamination reaction.

Hydrocortisone interacts with endoplasmic reticulum stress in hypoxic regulation of phosphoserine aminotransferase 1 gene expression differently in normal human astrocytes and glioblastoma cells

Endocrine Regulations
Objective. Endoplasmic reticulum (ER) stress and hypoxia are key factors for the effective growth of malignant tumors, including glioblastoma. The phosphoserine aminotransferase 1 (PSAT1) is an ER stress-responsive enzyme responsible for serine synthesis

Examination of the effects of microRNA-145-5p and phosphoserine aminotransferase 1 in colon cancer. [PDF]

Bioengineered, 2022
Previous studies manifested that microRNA-145-5p is pivotal in the development of various cancers. Nevertheless, the potential function of microRNA-145-5p in colorectal cancer remains unclear. This study attempted to investigate the potential role and possible mechanism of microRNA-145-5p in colon cancer.

Abstract P1-01-15: Investigation of phosphoserine aminotransferase 1 and its role in breast cancer progression

Cancer Research, 2018
Abstract 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 ...

The protective effects of phosphoserine aminotransferase 1 (PSAT1) against hepatic ischemia-reperfusion injury. [PDF]

J Cell Commun Signal, 2023
Hepatic ischemia-reperfusion (I/R) injury is a severe clinical syndrome, causing a profound medical and socioeconomic burden worldwide. This study aimed to explore underlying biomarkers and treatment targets in the progression of hepatic I/R injury. We screened gene expression profiles of the hepatic I/R injury from the Gene Expression Omnibus (GEO ...

Abstract 3563: Potential role for a phosphoserine aminotransferase 1 and pyruvate kinase M2 (PSAT1:PKM2) functional interaction in lung cancer cells

Cancer Research, 2017
Abstract Cellular production of serine provides precursors for numerous anabolic reactions, particularly for proteins and nucleic acid synthesis and for one carbon metabolism, and this pathway has been demonstrated to be elevated in many different cancer types.
