AMPK-HIF-1α signaling enhances glucose-derived de novo serine biosynthesis to promote glioblastoma growth

open access: yesJournal of Experimental & Clinical Cancer Research, 2023
Background Cancer cells undergo cellular adaptation through metabolic reprogramming to sustain survival and rapid growth under various stress conditions. However, how brain tumors modulate their metabolic flexibility in the naturally serine/glycine (S/G)-

Comparison of kinetic and enzymatic properties of intracellular phosphoserine aminotransferases from alkaliphilic and neutralophilic bacteria

open access: yesOpen Chemistry, 2020
Intracellular pyridoxal 5´-phosphate (PLP) -dependent recombinant phosphoserine aminotransferases (PSATs; EC 2.6.1.52) from two alkaliphilic Bacillus strains were overproduced in Escherichia coli, purified to homogeneity and their enzymological ...

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

open access: yesDiabetes, 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 ...

RNA-Seq of Phenotypically Distinct Eimeria maxima Strains Reveals Coordinated and Contrasting Maturation and Shared Sporogonic Biomarkers with Eimeria acervulina

open access: yesPathogens, 2023
Strains of Eimeria maxima, an enteric parasite of poultry, vary in virulence. Here, we performed microscopy and RNA sequencing on oocysts of strains APU-1 (which exhibits more virulence) and APU-2.

Characterization of human phosphoserine aminotransferase involved in the phosphorylated pathway of l-serine biosynthesis [PDF]

open access: yesBiochemical Journal, 2003
In the present study, we first report two forms of human phosphoserine aminotransferase (PSAT) cDNA (HsPSATα and HsPSATβ). HsPSATα has a predicted open reading frame comprising 324 amino acids, encoding a 35.2 kDa protein (PSATα), whereas HsPSATβ consists of an open reading frame comprising 370 amino acids that encodes a 40 kDa protein (PSATβ).

Genomic insight and physiological characterization of thermoacidophilic Alicyclobacillus isolated from Yellowstone National Park

open access: yesFrontiers in Microbiology, 2023
IntroductionAlicyclobacillus has been isolated from extreme environments such as hot springs, volcanoes, as well as pasteurized acidic beverages, because it can tolerate extreme temperatures and acidity.

Targeting PSAT1 to mitigate metastasis in tumors with p53-72Pro variant

open access: yesSignal Transduction and Targeted Therapy, 2023
The single-nucleotide polymorphism (SNP) of p53, in particular the codon 72 variants, has recently been implicated as a critical regulator in tumor progression. However, the underlying mechanism remains elusive.

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

open access: yesFood Biomacromolecules, EarlyView.
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.

The Role of One‐Carbon Metabolism in Cancer and Its Therapeutic Significance

open access: yesMedComm – Oncology, Volume 5, Issue 1, March 2026.
One‐Carbon metabolism in T‐cell activation and tumor competition. T‐cell activation shifts metabolic pathways, promoting anabolic metabolism and bioenergetic capacity. One‐carbon metabolism plays a crucial role in histone and DNA methylation in activated T cells.
