After DNA damage, PARP-1 is responsible for approximately 90% of the total cellular PARylation activity. Numerous studies showed activation of PARP-1 in various conditions associated with oxidative and nitrosative stress, such as ischemia-reperfusion injury, diabetes mellitus, and inflammation, and also proved the beneficial effects of PARP inhibitors. Several pharmacological inhibitors of PARP moved toward clinical testing for a variety of indications, including cardioprotection and malignant tumors, and in late 2014, olaparib became the first PARP inhibitor approved for human use for the therapy of ovarian cancer. These advances necessitate the detection of PARP activation in human tissues. In the present chapter, we review specific methods used to detect PARP activation in human circulating leukocytes and in human tissue sections.","is_dataset_classified":null,"base_score":1.791759469228055,"endowment":1.791759469228055,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"28695500","pmcid":null,"openalex_id":"https://openalex.org/W4236143807","authors":[],"funders":[],"total_grants":0,"fwci":3.3895,"citation_percentile":0.94927977,"influential_citations":0,"citation_trend":[{"year":2017,"count":1},{"year":2019,"count":1},{"year":2021,"count":1},{"year":2022,"count":1},{"year":2026,"count":1}],"oa_status":"closed","license":"http://www.springer.com/tdm","oa_locations":[{"url":"http://link.springer.com/content/pdf/10.1007/978-1-4939-6993-7_2","host_type":"publisher"},{"url":"https://doi.org/10.1007/978-1-4939-6993-7_2","host_type":"book series"}],"fields_of_study":["PARP inhibition in cancer therapy","Electrostatic Discharge in Electronics","Toxin Mechanisms and Immunotoxins","Animals","Biopsy","DNA Damage","Humans","Immunohistochemistry","Leukocytes","Poly (ADP-Ribose) Polymerase-1","Poly Adenosine Diphosphate Ribose","Poly(ADP-ribose) Polymerases","Protein Processing, Post-Translational"],"mesh_terms":["Leukocytes","Animals","Humans","DNA Damage","Poly(ADP-ribose) Polymerases","Poly Adenosine Diphosphate Ribose","Biopsy","Immunohistochemistry","Protein Processing, Post-Translational","Poly (ADP-Ribose) Polymerase-1"],"keywords":["Poly ADP ribose polymerase","Olaparib","PARP inhibitor","Ex vivo","NAD+ kinase","Cancer research","Oxidative stress","DNA damage","Chemistry","Biology","Pharmacology","Cell biology","Polymerase","Biochemistry","In vitro","Enzyme","DNA","Immunohistochemistry","PARP","Biopsy","Dab","Poly(adp-ribose)","Circulating Leukocytes"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Good health and well-being"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-10T22:01:01.159730Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
