Elevated levels of DPP4 are strongly linked to the clinical aggressiveness of upper tract urothelial carcinoma (UTUC). However, sitagliptin's impact on UTUC is poorly understood and requires further research.Patients and methods: This research utilized real-time PCR and immunohistochemistry to measure DPP4 mRNA and protein expression in UTUC. Sitagliptin's effects on cell proliferation and apoptosis were assessed using the alamarBlue assay and annexin V staining in UTUC cell lines. Migration ability was evaluated through wound-healing and transwell migration assays. The combined effect of sitagliptin and cisplatin on UTUC cell viability was also examined using both UTUC cell lines and patient-derived organoids.Results: Elevated DPP4 expression correlates with advanced tumor stages and reduced cancer-specific survival in UTUC. Sitagliptin treatment significantly reduced cell proliferation and enhanced apoptosis. Moreover, sitagliptin inhibited UTUC cell migration. Western blot results showed that sitagliptin treatment led to increased levels of apoptotic markers and reduced phosphorylation of AKT. It also influenced the phenotypical markers associated with epithelial-mesenchymal transition. Adding sitagliptin to cisplatin therapy did not show diminished antitumor efficacy compared with the effects of cisplatin alone.Conclusion: Sitagliptin inhibits the proliferation and migration of UTUC cells, promotes apoptosis, and influences the phenotypical transition from mesenchymal to epithelial states, likely via modulation of the AKT pathway. Sitagliptin may not cause chemotherapy resistance when combined with cisplatin treatment. These findings highlight its potential as an adjuvant therapy in UTUC.","PeriodicalId":8072,"journal":{"name":"Anticancer research","volume":"45 3","pages":"1001-1013"},"PeriodicalIF":1.6,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143555645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

NEAT1's regulation of oocyte maturation and its influence on tumor dynamics and cellular communication within the FF is well-established. In the ovarian tumor microenvironment, NEAT1 contributes to cellular proliferation, invasion, chemoresistance, and apoptosis. Moreover, its dysregulation correlates with poor prognosis and increased tumor aggressiveness, underscoring its potential as a therapeutic target. The interaction of NEAT1 with miRNAs and signaling pathways further highlights its significant role in ovarian cancer progression and its potential as a biomarker. This review explores NEAT1's contributions to ovarian cancer progression, its influence within the follicular fluid microenvironment, and its therapeutic potential as a target to combat ovarian cancer development and drug resistance.","PeriodicalId":8072,"journal":{"name":"Anticancer research","volume":"45 3","pages":"825-842"},"PeriodicalIF":1.6,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143555638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study evaluated the short-term safety of robot-assisted rectal surgery (RARS) in patients aged 75 years and older, examining perioperative complications and surgical outcomes in this vulnerable population.Patients and methods: A single-center retrospective cohort study was conducted at Okayama University Hospital from September 2020 to December 2024, including 109 patients undergoing RARS. Patients were divided into older (≥75 years, n=19) and non-older (<75 years, n=90) groups.

Postoperative complications were more frequent in the older group (8 vs. 18 cases, p=0.04), though severe complications were similar to those in the non-older group.

Flow cytometry analysis revealed cell cycle arrest at the S phase. Additionally, RFC2 knockdown markedly inhibited the migration and invasion of cervical cancer cells. These results demonstrate the critical involvement of RFC2 in regulating proliferation and metastatic potential in cervical cancer cells.Conclusion: RFC2 plays a pivotal role in promoting cervical cancer progression by enhancing cell growth, regulating the cell cycle, and promoting metastatic behavior.
