Contribution of One‐Electron Oxidation of Purine and Pyrimidine Bases to the Photo‐ and Radiation‐Induced Damage to Cellular DNA

ChemPhysChem, Volume 27, Issue 15, 14 August 2026.
One‐electron oxidation of purine and pyrimidine bases of isolated and cellular DNA generates related reactive base radical cations that are converted into final decomposition products through deprotonation and hydration. In the case of guanine, the most susceptible nucleobase to one‐electron oxidants, 8‐hydroxy‐7,8‐dihydroguanyl radical, thus formed by

Heterozygous loss‐of‐function alleles associate the conserved 3′‐5′ exoribonuclease EXOSC10 with hypersensitivity to the anticancer drug 5‐fluorouracil

Molecular Oncology, Volume 20, Issue 8, Page 1913-1932, August 2026.
EXOSC10, an essential nuclear RNA exosome‐associated 3′‐5′ exoribonuclease, is inhibited by the anticancer drug 5‐fluorouracil (5‐FU), and EXOSC10 depletion increases 5‐FU sensitivity. The colon‐cancer variant EXOSC10S402T, located in a proteolysis motif, is stable and nuclear but nonfunctional in vivo.

Repair and DNA Polymerase Bypass of Clickable Pyrimidine Nucleotides

Biomolecules
Clickable nucleosides, most often 5-ethynyl-2′-deoxyuridine (EtU), are widely used in studies of DNA replication in living cells and in DNA functionalization for bionanotechology applications.

A Modular Nucleoside Kinase Cascade for the Synthesis of Ribonucleoside Triphosphates

Biotechnology and Bioengineering, Volume 123, Issue 8, Page 2180-2191, August 2026.
Damm et al. report standardized enzymatic cascades for production of all canonical nucleoside triphosphates from the corresponding nucleosides, using kinase‐catalyzed phosphorylation from acetyl phosphate. Reactions afforded ∼ 100 mM product in near‐quantitative conversion.

Identification of novel genes regulating the development of the palate

Developmental Dynamics, Volume 255, Issue 8, Page 808-823, August 2026.
Abstract Background The International Mouse Phenotyping Consortium (IMPC) has generated thousands of knockout mouse lines, many of which exhibit embryonic or perinatal lethality. Using micro‐computed tomography (micro‐CT), the IMPC has created and publicly released three‐dimensional image data sets of embryos from these lethal and subviable lines.

Neq2X7: a multi-purpose and open-source fusion DNA polymerase for advanced DNA engineering and diagnostics PCR

BMC Biotechnology
Thermostable DNA polymerases, such as Taq isolated from the thermophilic bacterium Thermus aquaticus, enable one-pot exponential DNA amplification known as polymerase chain reaction (PCR). However, properties other than thermostability - such as fidelity,

De novo or Salvage? Nucleotide Availability as a Driver of Bacterial Adaptation and Virulence

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
Bacterial pathogens survive in different host environments by switching between making nucleotides by de novo synthesis and scavenging them from the host. This flexibility supports growth and virulence making nucleotide metabolism an attractive therapeutic target.

Metabolic Signatures of Aging and Gametogenesis in Hydra oligactis

Aging Cell, Volume 25, Issue 8, August 2026.
Hydra oligactis undergoes cold‐induced sexual differentiation and aging, culminating in death. GC–MS‐based metabolite profiling revealed signatures of gametogenesis, for example, polyamine accumulation, and of aging, such as loss of cytoprotection and neurotransmitter function, including taurine depletion.

Emerging experimental and bioinformatic approaches in RNA interference‐based pest control research

Insect Molecular Biology, Volume 35, Issue 4, Page 364-375, August 2026.
Double‐stranded RNA (dsRNA) visualization, RNA‐induced silencing complex (RISC)‐bound sRNA‐seq and RNA degradomics allow investigating dsRNA uptake and processing, guide small interfering RNA selection and RISC‐mediated target mRNA cleavages. Transcriptomic and proteomic profiles of genome‐wide responses to dsRNA, including off‐target and compensatory ...

Mechanical stimulation-induced purinome priming fosters osteogenic differentiation and osteointegration of mesenchymal stem cells from the bone marrow of post-menopausal women

Stem Cell Research & Therapy
Background Mechanical stimulation (MS) significantly increases the release of adenine and uracil nucleotides from bone marrow-derived mesenchymal stem cells (BM-MSCs) undergoing osteogenic differentiation.
