The unique catalytic properties of PSAT1 mediate metabolic adaptation to glutamine blockade

open access: yesNature Metabolism
Cultured cancer cells frequently rely on the consumption of glutamine and its subsequent hydrolysis by glutaminase (GLS). However, this metabolic addiction can be lost in the tumour microenvironment, rendering GLS inhibitors ineffective in the clinic. Here we show that glutamine-addicted breast cancer cells adapt to chronic glutamine starvation, or GLS

A GmeIF2B5‐GmPRX4 Regulatory Axis Divergently Governs Drought‐Lignin and Salt‐Ion Homeostasis in Soybean

open access: yesPlant Biotechnology Journal, Volume 24, Issue 4, Page 2405-2418, April 2026.
ABSTRACT Abiotic stresses severely constrain soybean productivity worldwide. Here we demonstrate that gmeif2b5 (eukaryotic initiation factors) mutants confer dual stress tolerance through coordinated mechanisms. Integrative RNA‐Seq and protein interaction analyses revealed that gmeif2b5 mutants increase lignin deposition to increase drought resilience ...

Cancer-immunity cycle-based molecular subtypes in breast cancer predict the response to immune checkpoint inhibitors

open access: yesCancer Biology & Medicine
Objective: The cancer-immunity cycle (CIC) outlines key steps of anti-tumor immunity from antigen release to T cell effector function. A comprehensive evaluation of the CIC in patients with breast cancer is lacking, which limits the accurate assessment ...

Modulating Purothionin Accumulation and Signal Peptide Cleavage Fine‐Tunes Wheat Flour Gluten Properties to Improve Cookie‐Making Quality

open access: yesAdvanced Science, Volume 13, Issue 16, 18 March 2026.
Dual genetic strategies for improving wheat processing quality by regulating purothionin accumulation to modulate gluten quantity and quality. The first strategy involves targeting signal peptide (SP) cleavage sites (e.g., through mutation) to indirectly reduce gluten content, thereby disrupting gluten network formation.

A novel balanced chromosomal translocation found in subjects with schizophrenia and schizotypal personality disorder: altered l-serine level associated with disruption of PSAT1 gene expression [PDF]

open access: yes, 2011
l-Serine is required for the synthesis of glycine and d-serine, both of which are NMDA receptor co-agonists. Although roles for d-serine and glycine have been suggested in schizophrenia, little is known about the role of the l-serine synthesizing cascade

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

open access: yes, 2017
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 ...

MicroRNA-340 Inhibits Esophageal Cancer Cell Growth and Invasion by Targeting Phosphoserine Aminotransferase 1

open access: yesCellular Physiology and Biochemistry, 2015
Background/Aims: Emerging evidence indicates that microRNA (miR)-340 is downregulated in various human cancers, suggesting that it acts as a tumor suppressor.

Non‐invasive and efficient diabetic retinal mitochondrial repair nanoplatform based on engineered endothelial mitochondrial‐derived vesicles with dynamic integrated stress response modulation

open access: yesInterdisciplinary Medicine, Volume 4, Issue 2, March 2026.
Under hyperglycemic conditions, mitochondrial dysfunction in retinal endothelial cells triggers excessive reactive oxygen species/reactive nitrogen species production, barrier protein degradation, and endothelial barrier breakdown in diabetic retinopathy.

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

open access: yesEndocrine 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
