Branched‐Chain Amino and Keto Acids Reduce Hepatocyte Lipid Droplet Size and Number via Distinct Proteomic Pathways

PROTEOMICS, Volume 26, Issue 7, Page 146-157, July 2026.
ABSTRACT Branched‐chain amino acids (BCAA) and their corresponding keto acids (BCKA) have been associated with changes in hepatic lipid metabolism and the resulting alterations in intracellular triglyceride concentrations. In this study, we utilized a previously established hepatocyte model to investigate the impact of BCAA and BCKA supplementation on ...

Dietary and biomarker‐guided strategies as supportive measures in the fragile X syndrome

Food Biomacromolecules, Volume 3, Issue 2, Page 237-251, June 2026.
Abstract The fragile X syndrome (FXS) is an inherited neurodevelopmental disorder that primarily affects males, often resulting in an IQ below 55, while about two‐thirds of females also experience intellectual disability. Physical features may include an elongated face, prominent ears, finger joint laxity, and enlarged testes in males.

Overexpression of Phosphoserine Aminotransferase 1 (PSAT1) Predicts Poor Prognosis and Associates with Tumor Progression in Human Esophageal Squamous Cell Carcinoma

Cellular Physiology and Biochemistry, 2016
Background/Aims: Phosphoserine aminotransferase 1 (PSAT1) is over-expressed in many carcinoma tissues, however little is known regarding its expression and function in esophageal carcinogenesis.

Human Cerebral Cortex Proteome of Fragile X-Associated Tremor/Ataxia Syndrome

Frontiers in Molecular Biosciences, 2021
Background: Fragile X-associated tremor/ataxia syndrome (FXTAS) is an adult-onset neurodegenerative disorder associated with premutation CGG-repeat expansions (55–200 repeats) in the 5′ non-coding portion of the fragile X mental retardation 1 (FMR1) gene.

Hepatic Phosphoserine Aminotransferase 1 Regulates Insulin Sensitivity in Mice via Tribbles Homolog 3 [PDF]

Diabetes, 2014
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 ...

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

Engineering a Synthetic Formatotrophic Yeast With Enhanced Growth Capacity on Formate

Advanced Energy and Sustainability Research, Volume 7, Issue 5, May 2026.
Engineering Yeast for Growth on Formate and Methanol via Serine‐Centered C1 Coupling. By engineering serine metabolism and remodeling the rGly pathway, we rendered yeast growth strictly dependent on formate. This synthetic formatotrophy enables growth on dual‐C1 substrates by channeling formate into the central metabolism via serine deaminases and ...

Rethinking the evolution of eukaryotic metabolism: novel cellular partitioning of enzymes in stramenopiles links serine biosynthesis to glycolysis in mitochondria

BMC Evolutionary Biology, 2017
Background An important feature of eukaryotic evolution is metabolic compartmentalization, in which certain pathways are restricted to the cytosol or specific organelles. Glycolysis in eukaryotes is described as a cytosolic process.
