Carthamus tinctorius L. (safflower) is known to exhibit effective antioxidant and anti-inflammatory properties; however its potential in renoprotective mechanisms remains poorly understood. The present study utilized a cisplatin-induced AKI mouse model to evaluate the renoprotective potential of CT (Carthamus tinctorius) extract. Integrated multi-omics along with in silico and in vivo approaches were used to elucidate the underlying mechanisms of action. The results initially demonstrated a rich phytochemical profile of CT extract characterized by abundant polysaccharides and flavonoids, with Hydroxysafflor Yellow A as a dominant bioactive constituent. In a cisplatin-induced acute kidney injury (AKI) mouse model, CT extract noticeably ameliorated the abnormalities of renal injury, as suggested by improved histopathology, reduced serum creatinine and BUN levels, and regulation of redox homeostasis. Metabolically, CT extract partially reversed AKI-associated disturbances by affecting 21 key metabolites, likely associated with histidine and alanine-aspartate-glutamate biosynthesis, and modulating amino acid and energy metabolism pathways. Concurrently, CT extract improved gut microbial homeostasis, increasing microbial diversity, normalizing the Firmicutes\/Bacteroidota ratio, suppressing pathogens, and enriching beneficial Ligilactobacillus. Network pharmacology and molecular docking identified AKT1, RELA, MAPK, and TP53 as central targets of core compounds (rutin and kaempferol derivatives), apparently targeting the PI3K-AKT and RELA (NF-kappaB) hubs. These results suggested that the renoprotective effects of CT extract are associated with transcriptional upregulation of the PI3K\/Akt\/Nrf2 pathway-related genes, increased expression of antioxidant genes (Ho-1, Sod1), and reduced expression of pro-inflammatory mediators (RelA, Cdk2) in the cisplatin-induced AKI mouse model.<\/jats:p>","DOI":"10.3390\/antiox15070855","type":"journal-article","created":{"date-parts":[[2026,7,9]],"date-time":"2026-07-09T16:16:44Z","timestamp":1783613804000},"page":"855","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Safflower Extract Ameliorates Cisplatin-Induced Acute Kidney Injury by Regulating Microbiota-Metabolic-Redox Nexus and PI3K\u2013Akt\/Nrf2 Pathway"],"prefix":"10.3390","volume":"15","author":[{"given":"Yue","family":"Chang","sequence":"first","affiliation":[{"name":"College of Life Sciences, Engineering Research Center of the Chinese Ministry of Education for Bioreactor and Pharmaceutical Development, Jilin Agricultural University, Changchun 130118, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanzhuo","family":"Song","sequence":"additional","affiliation":[{"name":"College of Life Sciences, Engineering Research Center of the Chinese Ministry of Education for Bioreactor and Pharmaceutical Development, Jilin Agricultural University, Changchun 130118, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2038-2838","authenticated-orcid":false,"given":"Naveed","family":"Ahmad","sequence":"additional","affiliation":[{"name":"Institute for Safflower Industry Research of Shihezi University\/Pharmacy College of Shihezi University\/Key Laboratory of Xinjiang Phytomedicine Resource and Utilization, Ministry of Education, Shihezi 832003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chao","family":"Song","sequence":"additional","affiliation":[{"name":"College of Life Sciences, Engineering Research Center of the Chinese Ministry of Education for Bioreactor and Pharmaceutical Development, Jilin Agricultural University, Changchun 130118, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuhang","family":"Chu","sequence":"additional","affiliation":[{"name":"College of Life Sciences, Engineering Research Center of the Chinese Ministry of Education for Bioreactor and Pharmaceutical Development, Jilin Agricultural University, Changchun 130118, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuru","family":"Zhang","sequence":"additional","affiliation":[{"name":"Institute for Safflower Industry Research of Shihezi University\/Pharmacy College of Shihezi University\/Key Laboratory of Xinjiang Phytomedicine Resource and Utilization, Ministry of Education, Shihezi 832003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lufei","family":"Feng","sequence":"additional","affiliation":[{"name":"Ginseng and Antler Products Testing Center of the Ministry of Agriculture PRC, Jilin Agricultural University, Changchun 130118, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7064-319X","authenticated-orcid":false,"given":"Wei","family":"Wei","sequence":"additional","affiliation":[{"name":"College of Animal Science and Technology, Jilin Agricultural Science and Technology College, Jilin 132101, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Min","family":"Zhang","sequence":"additional","affiliation":[{"name":"Ginseng and Antler Products Testing Center of the Ministry of Agriculture PRC, Jilin Agricultural University, Changchun 130118, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiuming","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Life Sciences, Engineering Research Center of the Chinese Ministry of Education for Bioreactor and Pharmaceutical Development, Jilin Agricultural University, Changchun 130118, China"},{"name":"Institute for Safflower Industry Research of Shihezi University\/Pharmacy College of Shihezi University\/Key Laboratory of Xinjiang Phytomedicine Resource and Utilization, Ministry of Education, Shihezi 832003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"53","DOI":"10.1038\/s41581-022-00631-7","article-title":"Cisplatin nephrotoxicity: New insights and therapeutic implications","volume":"19","author":"Tang","year":"2023","journal-title":"Nat.
