The regulatory landscape of the human HPF1- and ARH3-dependent ADP-ribosylome
Nature Communications, 2021 ADP-ribosylation is regulated by HPF1 and ARH3, but the cellular target spectrum of these enzymes is not fully understood. Here, the authors use quantitative proteomics to define the HPF1- and ARH3-dependent ADP-ribosylome, providing evidence that mono ...

The potential role and application of PARP inhibitors in cancer treatment [PDF]
, 2009 Background: Since many anti-cancer agents act by inflicting DNA damage on tumour cells, there is increasing interest in the use of inhibitors of DNA repair to increase the cytotoxicity of these agents.

The ADP-Ribosylating Toxins of Salmonella [PDF]
Toxins, 2019 A number of pathogenic bacteria utilize toxins to mediate disease in a susceptible host. The foodborne pathogen Salmonella is one of the most important and well-studied bacterial pathogens. Recently, whole genome sequence characterizations revealed the presence of multiple novel ADP-ribosylating toxins encoded by a variety of Salmonella serovars.

Regulation of Rad52-dependent replication fork recovery through serine ADP-ribosylation of PolD3
Nature Communications, 2023 Although Poly(ADP-ribose)-polymerases (PARPs) are key regulators of genome stability, how site-specific ADP-ribosylation regulates DNA repair is unclear.

Inhibition of Poly(ADP-Ribose) polymerase enhances the toxicity of 131I-Metaiodobenzylguanidine/Topotecan combination therapy to cells and xenografts that express the noradrenaline transporter [PDF]
, 2012 Targeted radiotherapy using [131I]meta-iodobenzylguanidine ([131I]MIBG) has produced remissions in some neuroblastoma patients. We previously reported that combining [131I]MIBG with the topoisomerase I (Topo-I) inhibitor topotecan induced long-term DNA ...

Proteome-wide identification of the endogenous ADP-ribosylome of mammalian cells and tissue
Nature Communications, 2016 ADP-ribosylation is a reversible post-translational protein modification involved in many cellular processes. Here the authors describe a sensitive approach for the analysis of ADP-ribosylation sites under physiologic conditions and identify lysine ...

ADP-Ribosylation Regulates the Signaling Function of IFN-γ
Frontiers in Immunology, 2021 Murine T cells express the GPI-anchored ADP-ribosyltransferase 2.2 (ARTC2.2) on the cell surface. In response to T cell activation or extracellular NAD+ or ATP-mediated gating of the P2X7 ion channel ARTC2.2 is shed from the cell surface as a soluble ...
