Fluorogenic Sydnones for Bioorthogonal Labeling of DNA
Conjugates of sydnones with cyanine‐styryl dyes combine bioorthogonal reactivity with fluorogenicity. The reactivity with bicyclo[6.1.0]non‐4‐yne (BCN)‐modified DNA showed second‐order rate constants of up to k2 = 2,300 M−1s−1 and fluorescence turn‐on by one magnitude of order.

Control of Gemcitabine Activity With Blue and Red Light
Treating cancer with chemotherapy is generally associated with many side effects, which can be addressed by selectively releasing the desired drugs with visible light. Sixteen new blue light‐activatable cytostatics were introduced, with the gemcitabine derivative exhibiting ideal properties.

Modulation of Epigenetic Control by Advanced Molecular Tweezers
Tailored dimeric molecular tweezers recognize the DNA‐binding part of Histone H4 and interrupt the essential histone‐DNA interaction. ABSTRACT This work addresses the question if supramolecular systems can be tailored to interfere with posttranslational modifications (PTM) and epigenetics.

Mutants Affecting Thymidine Metabolism in Neurospora crassa [PDF]
When 14C-thymidine labeled only in the ring is administered to Neurospora crassa, the majority of the recovered label is found in the ribonucleic acid (RNA).

Thymidine kinase diversity in bacteria
Thymidine kinases (TKs) appear to be almost ubiquitous and are found in nearly all prokaryotes, eukaryotes, and several viruses. They are the key enzymes in thymidine salvage and activation of several anti-cancer and antiviral drugs.

Jaw‐specific stem cell dynamics are associated with distinct enamel architecture in mouse incisors
Abstract Background The continuously growing mouse incisor serves as a model for stem cell‐driven tooth renewal. Although mice possess maxillary and mandibular incisors, most studies have focused on the mandible. Potential differences in structure and renewal between these serially homologous organs remain insufficiently characterized.

The deficiency of PNLDC1 exacerbates the advancement of CRC. PNLDC1 interacts with TUBB4B mRNA to regulate the p53–p21–CDK2–cyclin E2 pathway, thereby influencing the G2/M phase of the cell cycle. ABSTRACT Colorectal cancer (CRC) remains a leading cause of cancer‐related mortality, highlighting the urgent need for novel therapeutic strategies.

A sulfur-containing nucleoside antibiotic from Photorhabdus
We report the discovery of 4′-thiothymidine (4′sT), a sulfur-containing nucleoside antibiotic produced by the nematode symbiont Photorhabdus asymbiotica.

Somatic cell reprogramming for Parkinson's disease treatment
The fundamental purpose of cell reprogramming to treat Parkinson's disease is to generate dopaminergic neurons (DAN) and do transplantation. There are two ways to accomplish this. One method is to induce cells into induced DA neurons (iDAN) directly or to induce cells into induced pluripotent stem cells and ultimately into iDAN in vitro. Another option
