Purine nucleosides replace cAMP in allosteric regulation of PKA in trypanosomatid pathogens

eLife
Cyclic nucleotide binding domains (CNB) confer allosteric regulation by cAMP or cGMP to many signaling proteins, including PKA and PKG. PKA of phylogenetically distant Trypanosoma is the first exception as it is cyclic nucleotide-independent and ...

C5-Azobenzene-substituted 2'-Deoxyuridine-containing Oligodeoxynucleotides for Photo-Switching Hybridization

Molecules, 2014
A new photoisomeric nucleoside dUAz bearing an azobenzene group at the C5-position of 2'-deoxyuridine was designed and synthesized. Photoisomerization of dUAz in oligodeoxynucleotides can be achieved rapidly and selectively with 365 nm (forward) and 450

Recyclable All‐in‐One Organo‐Photo‐Auxiliaries Enabling (sp3)C−(sp3)C Coupling Reactions with Diverse Functionalities

Advanced Synthesis &Catalysis, Volume 367, Issue 5, March 4, 2025.
Abstract Photochemical C−C coupling reactions can be tailored to industrial chemical processes and preparations of pharmaceuticals. Recent approaches in this area are limited to using precious transition metal coordination complexes that facilitate light absorption and redox processes with benchtop chemicals. Herein, we propose a paradigm that involves

Silica Monolithic Capillary Columns for Hilic Separations

Hungarian Journal of Industry and Chemistry, 2018
The monolithic capillary columns (0.1 mm x 150 mm) prepared by the acidic hydrolysis of tetramethoxysilane (TMOS) in the presence of polyethylene glycol (PEG) and urea were modified by zwitterionic stationary phases and evaluated under HILIC separation ...

Role of Nucleoside Transporters in Nucleoside-Derived Drug Sensitivity

Nucleosides, Nucleotides and Nucleic Acids, 2010
Nucleoside-derived drugs are currently used clinically as anticancer drugs. To exert their pharmacological action first they need to enter into the cell across plasma membrane transporters and be metabolized. Thus, efficacy of treatment and acquisition of resistance can rely on a variety of events.

Topoisomerase I Inhibition in ETV4‐overexpressed Non‐Small Cell Lung Cancer Promotes Replication and Transcription Mediated R‐Loop Accumulation and DNA Damage

Advanced Science, EarlyView.
The oncogenic ETS factor ETV4 exerts a pleiotropic control over DNA replication both in a transcription‐dependent and ‐independent fashion in NSCLC cells. High‐ETV4 expression leads to R‐loop formation and DNA damage in response to TOP1 inhibition.

Metabolic Stress‐Induced Choline Kinase α (CHKA) Activation in Endothelial Subpopulation Contributes to Diabetes‐Associated Microvascular Dysfunction

Advanced Science, EarlyView.
This study uncovers CHKA as a pivotal driver of vascular dysfunction in diabetic retinopathy and highlights its role in endothelial dysfunction through NAD⁺‐SIRT1‐Notch signaling. Single‐cell and functional analyses, combined with clinical and genetic validation, suggest CHKA as a promising therapeutic target for the prevention and treatment of ...

RSPO2 Coordinates with GDF9:BMP15 Heterodimers to Promote Granulosa Cell and Oocyte Development in Mice

Advanced Science, EarlyView.
RSPO2 and GDF9:BMP15 heterodimers—core components of oocyte‐secreted factors (OSFs)—coordinate to shape the molecular architecture of preantral granulosa cells via gene‐specific synergistic and antagonistic regulation, mediated through CTNNB1–SMAD2 signaling crosstalk.
