RNA‐centric world of retroviruses: unravelling the molecular strategies of genomic RNA packaging
Biological Reviews, EarlyView.ABSTRACT Retroviruses constitute a unique group of RNA viruses that have profoundly influenced both evolutionary trajectories and biomedical research. Their ability to reverse transcribe and integrate into host genomes has shaped genomic architecture across species and contributed to our understanding of oncogenes, gene regulation, and RNA biology ...

Control of Gemcitabine Activity With Blue and Red Light
Chemistry – A European Journal, EarlyView.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.

Uncatalyzed Guanosine Phosphorylation under Potentially Prebiotic Conditions
Chemistry – A European Journal, EarlyView.Pyrophosphate acts as phosphorylating agent of guanosine under simple wet‐dry cycles without condensing agent and inorganic catalysts to afford cyclic guanosine monophosphate derivatives useful for oligomerization in prebiotic processes. ABSTRACT The phosphorylation of nucleosides and their subsequent polymerization are key issues in the study of the ...

Transcriptomic Profiling of SLC and ABC Transporters in the Human Term Placenta
Clinical Pharmacology &Therapeutics, EarlyView.Solute carriers (SLC) and ATP‐binding cassette (ABC) transporters are essential for placental solute exchange and fetal protection, yet their transcriptomic profiles in the human placenta remain poorly characterized. Although fetal sex influences placental development and function, its impact on transporter expression is unclear.
