MetabolomicsThe Poly (ADP-Ribose) Polymerase inhibitor Veliparib and Radiation Cause Significant Cell Line Dependent Metabolic Changes in Breast Cancer Cells
Breast tumors are characterized into different subtypes based on their surface marker expression, which affects their prognosis and treatment. For example, triple negative breast cancer cells (ER-/PR-/Her2-) show reduced susceptibility towards radiotherapy and chemotherapeutic agents. Poly (ADP-ribo...

MetabolomicsMetabolic responses induced by DNA damage and poly (ADP-ribose) polymerase (PARP) inhibition in MCF-7 cells
Genomic instability is one of the hallmarks of cancer. Several chemotherapeutic drugs and radiotherapy induce DNA damage to prevent cancer cell replication. Cells in turn activate different DNA damage response (DDR) pathways to either repair the damage or induce cell death. These DDR pathways also e...

TranscriptomicsRNAi of human MCF7 cells knocked down for PARP-1 or PARGs
Poly(ADP-ribose) polymerase-1 (PARP-1) and poly(ADP-ribose) glycohydrolase (PARG) are enzymes that modify target proteins in the nucleus by the addition and removal, respectively, of ADP-ribose polymers. Although a role for PARP-1 in gene regulation has been well established, the role of PARG is le...

ProteomicsPARG is Essential for Pol-theta-Mediated DNA End-Joining by Removing Repressive Poly-ADP Ribose Marks
DNA polymerase theta (Pol-theta)-mediated end-joining (TMEJ) repairs DNA double-strand breaks and confers resistance to genotoxic agents. How Pol-theta is regulated at the molecular level to exert TMEJ remains unknown. We find that Pol-theta interacts with and is PARylated by PARP1 in vitro and in c...

GenomicsEssential role of poly(ADP-ribosyl)ation in cocaine action
Many of the long-term effects of cocaine on the brain's reward circuitry have been shown to be mediated by alterations in gene expression. Several chromatin modifications, including histone acetylation and methylation, have been implicated in this regulation, but the effect of other histone modifica...

TranscriptomicsMechanistic Rationale for Inhibition of Poly(ADP-Ribose) Polymerase in ETS Gene Fusion Positive Prostate Cancer
To identify commonly altered genes between ERG, PARP1, and DNA-PKcs. Two-condition experiment: Each siRNA, targeting either DNA-PKcs or PARP1, was compared to a control RNA.

TranscriptomicsPaternal poly(ADP-ribose) metabolism modulates retention of inheritable sperm histones and early embryonic gene expression [PJ34_sperm_MNaseb]
To achieve the extreme nuclear condensation necessary for sperm function, most histones are replaced with protamines during spermiogenesis in mammals. Mature sperm retain only a small fraction of nucleosomes, which are, in part, enriched on gene regulatory sequences, and recent findings suggest tha...

ProteomicsEngineering Af1521 macro domain increases ADP-ribose binding affinity and leads to the identification of more ADP-ribosylated proteins
Protein ADP-ribosylation is a covalent, reversible post-translational modification that has important functions in several cellular mechanisms. The identification of modified proteins in cells has proven challenging and, due to the low abundance of protein ADP-ribosylation, has mainly been possible ...

TranscriptomicsMRE11 Deficiency Increases Sensitivity to Poly(ADP-ribose) Polymerase Inhibition in Microsatellite Unstable Colorectal Cancers.
We have performed bioinformatic approaches to identify the level of enrichment between gene expression profiles characterizing MSI tumors and gene changes induced in vitro by the PARP-1 inhibitor Phenanthridinone and others using the Connectivity Map tool. In a first step, we have anyzed the express...

ProteomicsEwing sarcoma protein-mediated regulation of poly(ADP-ribose) polymerase 1 dissociation
Poly(ADP-ribose) polymerase 1 (PARP1) critically facilitates DNA damage response (DDR) that suppresses genomic instability. However, the physiological function of PARP1 in regulating genomic integrity is unclear. We investigated the Ewing’s sarcoma breakpoint region 1 (EWS) and found that it regulat...
