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

MedComm – 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.

P.067 Phosphoserine aminotransferase (PSAT) deficiency: Imaging findings in a child with congenital microcephaly [PDF]

Canadian Journal of Neurological Sciences / Journal Canadien des Sciences Neurologiques, 2018
Background: Serine deficiency disorders can result from deficiency in one of three enzymes. Deficiency of the second enzyme in the serine biosynthesis pathway, 3-phosphoserine aminotransferase (PSAT), has been reported in two siblings when the eldest was investigated for acquired microcephaly, progressive spasticity and intractable epilepsy.

Post‐translational regulation of human D‐3‐phosphoglycerate dehydrogenase in Alzheimer's disease

Protein Science, Volume 35, Issue 3, March 2026.
Abstract Emerging evidence suggests that sex‐specific differences in L‐serine (L‐Ser) metabolism play a key role in Alzheimer's disease (AD). While disruptions in amino acid balance are well known, recent findings point to a dimorphic regulation of the serine biosynthetic pathway.

Bioinformatics‐based discovery of the involvement of PSAT1 in mediating the anti‐lung adenocarcinoma activity of triptolide

Animal Models and Experimental Medicine, Volume 9, Issue 1, Page 115-127, January 2026.
Transcriptome sequencing was performed on tumor tissues from triptolide‐treated tumor‐bearing mice. The sequencing results were integrated with data from public databases for comprehensive analysis, and potential regulatory targets of triptolide were identified.

Skullcapflavone II Inhibits SLC1A4‐Mediated L‐Serine Uptake and Promotes Mitochondrial Damage in Gastric Cancer

Advanced Science, Volume 12, Issue 45, December 4, 2025.
Skullcapflavone II (SkII) significantly alters serine metabolism in gastric cancer cells by directly targeting the L‐serine transporter SLC1A4, thereby inhibiting L‐serine uptake rather than de novo synthesis. This disruption of serine metabolism by SkII leads to increased oxidative stress and consequent mitochondrial damage.

Unfolded protein response kinase PERK supports survival and metastasis of circulating tumor cell clusters via SAM synthesis and H3K4me3‐dependent PDGFB signaling

Cancer Communications, Volume 45, Issue 12, Page 1706-1733, December 2025.
Abstract Background Metastasis is the leading cause of cancer‐related mortality, with circulating tumor cell (CTC) clusters serving as highly efficient precursors of distant metastasis. Survival of CTC clusters in the bloodstream is the primary contributor to tumor metastasis.

Modulating the serine metabolism in human differentiated astrocytes: an integrated multi omics approach

Frontiers in Cellular Neuroscience
IntroductionAstrocytes are the major source of L-serine (L-Ser) in the brain: the glycolytic intermediate D-3-phosphoglycerate is converted into L-Ser through the phosphorylated pathway (PP) made up of three enzymes, phosphoglycerate dehydrogenase (PHGDH)

Comparison of odontogenic differentiation of human dental follicle cells and human dental papilla cells.

PLoS ONE, 2013
Classical tooth development theory suggests that dental papilla cells (DPCs) are the precursor cells of odontoblasts, which are responsible for dentin development.

In Vivo Biosynthesis and Direct Incorporation of Noncanonical Amino Acids into Proteins

ChemBioChem, Volume 26, Issue 22, November 17, 2025.
This review evaluates engineered (semi)autonomous cell systems for the biosynthesis and incorporation of noncanonical amino acids (ncAAs) into proteins. While semi‐autonomous cells convert supplied precursors into ncAAs autonomous cells integrate biosynthetic pathways that produce these building blocks intracellularly.
