The discovery of small molecule inhibitors of poly(ADP-ribose) mediated cell death [PDF]

open access: yes, 2011
The emergence of resistance to cancer treatments through methods that generate cell death by inducing DNA damage, such as chemotherapeutics and radiation therapy, is a major obstacle to overcoming the disease.

Selective N‐Functionalization of Pyrazoles

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
This review traces the evolution of regioselective N‐functionalization strategies for pyrazoles, a key class of nitrogen heterocycles widely used in medicinal chemistry. Due to rapid tautomerism, N‐functionalization often lacks selectivity, leading to poor and unpredictable regioisomeric outcomes.

ADP-ribosylation: from molecular mechanisms to human disease [PDF]

open access: yesGenetics and Molecular Biology
Post-translational modification of proteins by ADP-ribosylation, catalysed by poly (ADP-ribose) polymerases (PARPs) using NAD+ as a substrate, plays central roles in DNA damage signalling and repair, modulates a range of cellular signalling cascades and ...

Synthesis of poly(ADP-ribose)-agarose beads: an affinity resin for studying (ADP-ribose)n-protein interactions.

open access: yes, 1992
Polymers of ADP-ribose bind chromatosomal histones in solution and may play a role in chromatin accessibility in vivo. We have enzymatically synthesized a poly(ADP-ribose) affinity resin to further characterize binding of nuclear proteins to ADP-ribose ...

Global Real‐World Outcomes of Olaparib in Metastatic Castration‐Resistant Prostate Cancer Patients With Homologous Recombination Repair Alterations

open access: yesInternational Journal of Cancer, EarlyView.
ABSTRACT Evidence to guide the treatment for patients with metastatic castration‐resistant prostate cancer (mCRPC) and Homologous Recombination Repair (HRR) gene alterations outside of clinical trials remains limited. This was an observational, cohort study, including mCRPC patients with tumor harboring HRR alterations, progressed on a prior androgen ...

Divalent and multivalent cations control liquid-like assembly of poly(ADP-ribosyl)ated PARP1 into multimolecular associates in vitro

open access: yesCommunications Biology
The formation of nuclear biomolecular condensates is often associated with local accumulation of proteins at a site of DNA damage. The key role in the formation of DNA repair foci belongs to PARP1, which is a sensor of DNA damage and catalyzes the ...

Cross‐Regulation Between DNA Methylation and Circadian Clock Reprogramming in Ovarian Cancer: Mechanistic Insights, Biomarker Potential, and Therapeutic Implications

open access: yesInternational Journal of Cancer, EarlyView.
ABSTRACT Early diagnosis remains challenging, recurrence rates remain high, and platinum resistance frequently develops in ovarian cancer (OC), collectively representing major barriers to long‐term patient survival. DNA methylation (DNAm), as a relatively stable yet dynamically modifiable epigenetic signature, can capture alterations in tumor states ...

Ovarian Cancer: Epidemiology, Disease Mechanisms, New Diagnosis and Treatment Strategies, and Research Directions

open access: yesiNew Medicine, EarlyView.
ABSTRACT Ovarian cancer (OC) continues to be the deadliest gynecological malignancy and a significant cause of cancer‐related mortality among women worldwide. Standard treatment strategies typically entail platinum‐based chemotherapy in conjunction with cytoreductive surgery.

PARG Mutation Uncovers Critical Structural Determinant for Poly(ADP-Ribose) Hydrolysis and Chromatin Regulation in Embryonic Stem Cells

open access: yesCells
Poly(ADP-ribosyl)ation is a crucial posttranslational modification that governs gene expression, chromatin remodeling, and cellular homeostasis. This dynamic process is mediated by the opposing activities of poly(ADP-ribose) polymerases (PARPs), which ...

The sound of silence: RNAi in poly (ADP-Ribose) research [PDF]

open access: yes, 2012
Poly(ADP-ribosyl)-ation is a nonprotein posttranslational modification of proteins and plays an integral part in cell physiology and pathology. The metabolism of poly(ADP-ribose) (PAR) is regulated by its synthesis by poly(ADP-ribose) polymerases (PARPs)
