Synthesis and calcium mobilization activity of cADPR analogues which integrate nucleobase, northern and southern ribose modifications [PDF]

open access: yes, 2012
Novel cADPR mimics, which integrate nucleobase, northern and southern ribose modifications were synthesized. The key steps of the synthesis were a Cu(I)-catalyzed Hüisgen [3+2] cycloaddition and a microwave-assisted intramolecular pyrophosphorylation ...

Prostate cancer and PARP inhibitors: progress and challenges

open access: yesJournal of Hematology & Oncology, 2021
Despite survival improvements achieved over the last two decades, prostate cancer remains lethal at the metastatic castration-resistant stage (mCRPC) and new therapeutic approaches are needed.

Human autoantibodies to poly(adenosine diphosphate-ribose) polymerase. [PDF]

open access: yesJournal of Clinical Investigation, 1987
The chromatin-bound enzyme poly(ADP-ribose) polymerase (ADPRP) is strongly stimulated by DNA with single- or double-stranded breaks, and transfers the ADP-ribose moiety of NAD to nuclear proteins. The activation of ADPRP is important for DNA repair and replication, and also has been postulated to play a role in the pathogenesis of lymphocyte ...

Identification of a dihydropyridine scaffold that blocks ryanodine receptors

open access: yesiScience, 2022
Summary: Ryanodine receptors (RyRs) are large, intracellular ion channels that control Ca2+ release from the sarco/endoplasmic reticulum. Dysregulation of RyRs in skeletal muscle, heart, and brain has been implicated in various muscle pathologies ...

Natural occurence of a biopolymer, poly (adenosine diphosphate ribose)

open access: yesNucleic Acids Research, 1977
Evidence for the natural occurrence of poly(adenosine diphosphate ribose) in vivo was obtained using a sensitive radioimmunoassay and poly(adenosine diphosphate ribose) glycohydrolase, which specifically hydrolyzes poly(adenosine diphosphate ribose).

Demonstration of high molecular weight poly (adenosine diphosphate ribose)

open access: yesNucleic Acids Research, 1978
An electrophoretic system was established that resolves poly(adenosine diphosphate ribose), enzymatically synthesized polymer from NAD+, by size difference of one residue on polyacrylamide gel. The existence of a polymer of at least 65 residues was demonstrated by band counting in this system. The polymer showed a heterogeneous size distribution on the

Salvage enzymes in nucleotide biosynthesis [PDF]

open access: yes, 2007
Balanced pools of deoxyribonucleoside triphosphates (dNTPs), the building blocks of DNA, and ribonucleoside triphosphates (NTPs), the precursors of RNA, are crucial for a controlled cell proliferation.

DNA repair and synthetic lethality [PDF]

open access: yes, 2011
Tumors often have DNA repair defects, suggesting additional inhibition of other DNA repair pathways in tumors may lead to synthetic lethality. Accumulating data demonstrate that DNA repair-defective tumors, in particular homologous recombination (HR ...

Controversies and clinical unknowns in the use of PARP inhibitors in ovarian cancer

open access: yesTherapeutic Advances in Medical Oncology
Poly (adenosine diphosphate-ribose) polymerase inhibitors (PARPi) have significantly improved the treatment of advanced ovarian cancer, however, there are still many aspects of their use that require further understanding.
