The cytotoxic response of mice bearing tumors that were not yet palpable was enhanced. However, as palpable tumors developed and tumor growth progressed, their cytotoxic capacity became suppressed. Concurrent with this decline in cytotoxic capacity, there was an increase in systemic immunoreactive prostaglandin E2 (PGE2) concentrations in tumor-bearing mice. Administration of indomethacin, a prostaglandin synthesis inhibitor, to LLC-bearing mice prevented the rise in PGE2 concentrations and the suppression in cytotoxic capacity toward LLC. A relationship between the elevated immunoreactive PGE2 levels, suppression in cytotoxic capacity, and progressive tumor growth was indicated when administration of indomethacin to tumor-bearing mice also reduced the rate of tumor development.","is_dataset_classified":null,"base_score":3.4339872044851463,"endowment":3.4339872044851463,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"2942724","pmcid":null,"openalex_id":"https://openalex.org/W2259809757","authors":[],"funders":[],"total_grants":0,"fwci":3.1769,"citation_percentile":0.92162736,"influential_citations":0,"citation_trend":[],"oa_status":"closed","license":null,"oa_locations":[{"url":"http://academic.oup.com/jnci/article-pdf/77/2/425/2782491/77-2-425.pdf","host_type":"publisher"},{"url":"https://doi.org/10.1093/jnci/77.2.425","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/2942724","host_type":"repository"}],"fields_of_study":["Inflammatory mediators and NSAID effects","Cancer, Stress, Anesthesia, and Immune Response","Chemokine receptors and signaling"],"mesh_terms":["Animals","Cytotoxicity, Immunologic","Immune Tolerance","Indomethacin","Lymphocyte Culture Test, Mixed","Lung Neoplasms","Mice, Inbred C57BL","Neoplasms, Experimental","Prostaglandins E","Spleen","Dinoprostone","Mice"],"keywords":["Cytotoxic T cell","Lewis lung carcinoma","Spleen","Prostaglandin","Prostaglandin E2","Prostaglandin E","Lung","Cancer research","Endocrinology","Internal medicine","Chemistry","Medicine","In vitro","Cancer","Biochemistry"],"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":"2026-08-11T18:56:37.371361Z","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":[]}
