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]
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 ...

HPF1 remodels the active site of PARP1 to enable the serine ADP-ribosylation of histones
Once DNA breaks occur, poly(ADP-ribose) polymerase 1 (PARP1) ADP-ribosylates itself and other DNA repair factors to initiate the repair process. Here, the authors resolve the crystal structures of mouse and human HPF1, and human HPF1/PARP1 complex ...

Mcl-1 suppresses abasic site repair following bile acid–induced hepatic cellular DNA damage
In cholestasis, increases in bile acid levels result in the generation of reactive oxygen species and the induction of DNA damage and mutation. It is believed that bile acid accumulation is associated with liver tumorigenesis. However, the mechanism that

Nitrosative Stress as a Modulator of Inflammatory Change in a Model of Takotsubo Syndrome
Summary: Previous studies have shown that patients with Takotsubo syndrome (TS) have supranormal nitric oxide signaling, and post-mortem studies of TS heart samples revealed nitrosative stress.

Inputs and outputs of poly(ADP-ribosyl)ation: Relevance to oxidative stress
Oxidative stress can cause DNA breaks which induce activation of the DNA nick sensor enzyme poly(ADP-ribose) polymerase-1 (PARP-1), part of the 17 member PARP enzyme family.

Mitochondria are devoid of poly(ADP‐ribose)polymerase‐1, but harbor its product oligo(ADP‐ribose)
There are conflicting data about localization of poly(ADP-ribose)polymerase-1 and its product poly(ADP-ribose) in mitochondria. To finally clarify the discussion, we investigated with biochemical and cell biological methods the potential presence of poly(

Tricyclic benzimidazoles as potent poly(ADP-ribose) polymerase-1 inhibitors
Novel tricyclic benzimidazole carboxamide poly-(ADP-ribose) polymerase-1 (PARP-1) inhibitors have been synthesized. Several compounds were found to be powerful chemopotentiators of temozolomide and topotecan in both A549 and LoVo cell lines.
