Molecular Oncology, EarlyView.Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

The Preparation of Nucleoside-Functionalized Silicone and Oligonucleotide-Silicone Copolymers [PDF]
, 2004 Attempts to prepare silicone oligonucleotide copolymers are complicated by the large difference in hydrophobicity in the two materials. Two approaches were followed to overcome this challenge.

Molecular Oncology, EarlyView.Single‐cell DNA methylation (scDNAme) profiling maps epimutational clonal evolution, revealing mechanisms of malignancy and therapeutic resistance across diverse cancer types. By providing a high‐resolution landscape of intratumoral heterogeneity, these technologies empower precise patient stratification, guide the development of enhanced ...

Do non-nucleoside reverse transcriptase inhibitors contribute to lipodystrophy? [PDF]
, 2005 Lipodystrophy complications, including lipoatrophy (pathological fat loss) and metabolic complications, have emerged as important long-term toxicities associated with antiretroviral therapy in the current era. The wealth of data that has accumulated over

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

Molecular Oncology, EarlyView.This review summarizes the transcription factors, repressive chromatin‐modifying complexes, and epigenetic mechanisms that control fetal hemoglobin repression. Notably, many regulators of γ‐globin silencing also function in transcriptional and epigenetic networks that drive cancer, highlighting opportunities to translate advances in hemoglobinopathy ...

Molecular cloning and characterization of nucleoside diphosphate kinase 1 cDNA in tea [PDF]
, 2012 Nucleoside diphosphate kinase (NDPK) operates in the homeostasis of cellular nucleoside triphosphate (NTP) pools and the cytosolic NDPK1 is the main NDPK isoform in plants, accounting for more than 70 % of total NDPK activity in plant. A full length cDNA

Profile of Nucleotides and Nucleosides in Taiwanese Human Milk
Pediatrics and Neonatology, 2011 Human milk–borne nucleotides and their related metabolic products have been reported to have important physiological roles in breast-fed infants. The purpose of this study was to measure the concentrations of free nucleotides and nucleosides in human ...

FEBS Open Bio, EarlyView.The MRP4 transporter exports several drugs and signaling molecules. Here, we identified key promoter elements regulating basal MRP4 expression. Using reporter assays, we defined a conserved region with essential Sp1 and contributory Ets sites, which controlled basal MRP4 expression.

Nucleoside Transport in Cultured Llc-Pk1 Epithelia [PDF]
, 1992 The transport of nucleosides by LLC-PK1 cells, a continuous epithelial cell line derived from pig kidney, was characterised. Uridine influx was saturable (apparent K(m) approximately 34-mu-M at 22-degrees-C) and inhibited by > 95% by ...
