Advances in large DNA fragment assembly for microbial cell factory engineering

open access: yesQuantitative Biology, Volume 14, Issue 3, September 2026.
Abstract The efficient, rapid, and reliable assembly of DNA fragments is essential for advancing metabolic engineering and synthetic biology. With the rapid advancement of DNA synthesis and assembly technologies, the scale of DNA assembly has expanded from single genes to metabolic pathways and even genomes.

Metabolic Fingerprints of High‐Risk Individuals for Pancreatic Cancer: A Multibiospecimen Investigation

open access: yesAnalysis &Sensing, Volume 6, Issue 4, July 2026.
This study presents a multimatrix untargeted metabolomics analysis of fecal, plasma, and urine samples from individuals at high risk for pancreatic cancer development. Integrated multivariate and cofactor‐adjusted models were applied to characterize cross‐matrix metabolomic associations, incorporating pancreatic magnetic resonance imaging data, sex ...

Nucleosides and Nucleotides. 175. Structural Requirements of the Sugar Moiety for the Antitumor Activities of New Nucleoside Antimetabolites, 1-(3-C-Ethynyl-β-d-ribo-pentofuranosyl)cytosine and -uracil

open access: yes, 2016
We previously designed 1-(3-C-ethynyl-β-d-ribo-pentofuranosyl)uracil (EUrd) and its cytosine congener (ECyd) as potential multifunctional antitumor nucleoside antimetabolites. They showed potent and broad-spectrum antitumor activity against various human

Pyruvate Kinase M2 Mediates Apigenin‐Induced Energy Crisis and Apoptosis in Colon Cancer Cells

open access: yesFood Frontiers, Volume 7, Issue 4, July 2026.
Apigenin, a dietary flavonoid with low toxicity, induces profound bioenergetic collapse in colon cancer cells by downregulating PKM2. This metabolic crisis, characterized by suppressed glycolysis and mitochondrial dysfunction, ultimately triggers robust apoptosis.

Deletion of the uracil permease gene confers cross-resistance to 5-fluorouracil and azoles in Candida lusitaniae and highlights antagonistic interaction between fluorinated nucleotides and fluconazole.

open access: yes, 2014
International audienceWe characterized two additional membrane transporters (Fur4p and Dal4p) of the nucleobase cation symporter 1 (NCS1) family involved in the uptake transport of pyrimidines and related molecules in the opportunistic pathogenic yeast ...

Oligomerization of Non‐Activated Nucleotides Under Hot Acidic Wet–Dry Cycling Without Catalytic Agents

open access: yesChemSystemsChem, Volume 8, Issue 4, July 2026.
Oligonucleotides form spontaneously through hot wet‐dry cycling of pure non‐activated nucleotides. No catalytic agents were added, and pH was naturally buffered by the nucleotides. Oligonucleotide formation was confirmed and quantified using mass spectrometry, spectroscopy and electrophoresis, establishing a solid baseline for the intrinsic extent of ...

Unique Features and Anti-microbial Targeting of Folate- and Flavin-Dependent Methyltransferases Required for Accurate Maintenance of Genetic Information

open access: yesFrontiers in Microbiology, 2018
Comparative genome analyses have led to the discovery and characterization of novel flavin- and folate-dependent methyltransferases that mainly function in DNA precursor synthesis and post-transcriptional RNA modification by forming (ribo) thymidylate ...
