Lineage-specific silencing of PSAT1 induces serine auxotrophy and sensitivity to dietary serine starvation in luminal breast tumors [PDF]

open access: yesCell Reports, 2022
A major challenge of targeting metabolism for cancer therapy is pathway redundancy, in which multiple sources of critical nutrients can limit the effectiveness of some metabolism-targeted therapies.

Interleukin-6 mediates PSAT1 expression and serine metabolism in TSC2-deficient cells [PDF]

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2021
Abstract Tuberous sclerosis complex (TSC) and lymphangioleiomyomatosis (LAM) are caused by aberrant mechanistic Target of Rapamycin Complex 1 (mTORC1) activation due to loss of either TSC1 or TSC2 . Cytokine profiling of TSC2-deficient LAM patient-

Psat1-Dependent Fluctuations in α-Ketoglutarate Affect the Timing of ESC Differentiation [PDF]

open access: yesCell Metabolism, 2016
Embryonic stem cells (ESCs) undergo coordinated epigenetic and metabolic changes to differentiate properly. However, the precise mechanisms by which these alterations are fine-tuned in the early stages of differentiation have not been identified. In this study, we demonstrate that phosphoserine aminotransferase 1 (Psat1), an Oct4/Sox2/Nanog (OSN ...

Overexpression of PSAT1 promotes metastasis of lung adenocarcinoma by suppressing the IRF1-IFNγ axis

Oncogene, 2020
An increasing number of enzymes involved in serine biosynthesis have been identified and correlated with malignant evolution in various types of cancer. Here we showed that the overexpression of phosphoserine aminotransferase 1 (PSAT1) is widely found in lung cancer tissues compared with nontumor tissues and predicts a poorer prognosis in patients with

Pathogenic PSAT1 Variants and Autosomal Recessive Axonal Charcot-Marie-Tooth Disease With Ichthyosis

Pediatric Neurology, 2023
Biallelic pathogenic phosphoserine aminotransferase 1 (PSAT1) variants generally cause a severe phenotype predominantly involving the central nervous system. Here, for the first time, we report two patients harboring pathogenic PSAT1 variants only manifested as polyneuropathy and ichthyosis.Two patients from unrelated families presenting with ...
