ELISA was performed to detect OS-related factors and inflammatory cytokines. Reactive oxygen species (ROS) levels and pyroptosis were analyzed using DCFH-DA and TUNEL staining. LPS and ATP induced HTR-8\/SVneo cells were co-transfected with sh-PRDX6\/sh-KLF9 to explore the potential regulatory effect of KLF9 on PRDX6.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      LPS+ATP stimulation increased KLF9 expression in the PE cell model.

Moreover, inhibiting KLF9 expression decreased protein expression of NLRP3, GSDMD-N, cleaved caspase-1, and cleaved-IL-1\u03b2, suppressing cell death in LPS+ATP-induced HTR-8\/SVneo cells. Analysis of OS indicators revealed that downregulating KLF9 expression restrained intracellular ROS production, decreased MDA expression, and increased SOD and CAT levels. KLF9 regulated the transcription of PRDX6 to attenuate OS and pyroptosis. Knockdown of PRDX6 partially abolished the effect of KLF9 downregulation on OS and pyroptosis of LPS+ATP-induced HTR-8\/SVneo cells, as evidenced by the inhibition of cell proliferation, migration, and invasion, as well as the enhanced activity of the NLRP3 inflammasome.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Downregulation of KLF9 enhances trophoblast cell invasion and reduces OS and NLRP3 inflammasome activation-mediated pyroptosis.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/09603271251324702","type":"journal-article","created":{"date-parts":[[2025,3,11]],"date-time":"2025-03-11T17:12:06Z","timestamp":1741713126000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":6,"title":["KLF9 mediates NLRP3 inflammasome and reactive oxygen species to mediate pyroptosis in trophoblasts"],"prefix":"10.1177","volume":"44","author":[{"given":"Qian","family":"Li","sequence":"first","affiliation":[{"name":"The 940th Hospital of Joint Logistics Support Force of Chinese People\u2019s Liberation Army, Lanzhou city, Gansu province, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-8807-3126","authenticated-orcid":false,"given":"Min","family":"Chen","sequence":"additional","affiliation":[{"name":"The Second Hospital of Lanzhou University, Lanzhou city, Gansu province, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,3,11]]},"reference":[{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41572-023-00417-6"},{"key":"e_1_3_4_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.siny.2020.101123"},{"key":"e_1_3_4_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajog.2021.11.1356"},{"key":"e_1_3_4_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajog.2021.12.001"},{"key":"e_1_3_4_6_2","doi-asserted-by":"publisher","DOI":"10.1111\/febs.15745"},{"key":"e_1_3_4_7_2","doi-asserted-by":"publisher","DOI":"10.1007\/s12035-021-02290-4"},{"key":"e_1_3_4_8_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.2003913117"},{"key":"e_1_3_4_9_2","doi-asserted-by":"publisher","DOI":"10.3390\/ijms232315174"},{"key":"e_1_3_4_10_2","doi-asserted-by":"publisher","DOI":"10.1002\/iid3.1043"},{"key":"e_1_3_4_11_2","article-title":"KLF9 aggravates streptozotocin-induced diabetic cardiomyopathy by inhibiting PPARgamma\/NRF2 signalling","volume":"11","author":"Li F","year":"2022","unstructured":"Li F, Peng J, Feng H, et al.
