To investigate the effect of microbiome-specific metabolites butyric on cervical cancer cells.\u003Cbr>Methods: We studied 416 vaginal 16S rRNA sequencing data and 116 gut sequencing data. Reads were processed using VSEARCH. We used Shannon index, Chao1 index, Simpson diversity index, β diversity index, Linear discriminant analysis Effect Size (LEfSe), co-abundance network and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis to explore microbiome differences between groups. We constructed random forest models based on genus and verified its discriminant effect. Finally, we used the cell counting kit-8 (CCK-8) method to detect cell proliferation capacity and flow cytometry to detect apoptosis and induction of cell cycle progression.\u003Cbr>Results: Compared to the non-cancerous population, patients with cervical cancer had unique microbial community characteristics in both vaginal and gut ecological niches. Our predictive model based on genus in two ecological regions achieved high accuracy in the diagnosis of cervical cancer (vaginal model AUC=91.58 %; gut model AUC=99.95 %). Butyric inhibited cervical cancer cell proliferation in a concentration-dependent manner and promoted apoptosis of cancer cells.\u003Cbr>Conclusion: Significant differences were found in vaginal and gut microbes in patients with cervical cancer compared to the non-cancerous population. The prediction models constructed at the genus level in both ecological sites have good diagnostic value. Microorganisms may be involved in cervical cancer progression in ametabolite-dependent way, and targeting butyric may provide therapeutic options for cervical cancer. |\n\nIntroduction  \nCervical cancer is a serious threat to women’s health. Its incidence and mortality rate are consistently among the top gynecologic malignancies [1], but vary widely in developed and developing countries.  \nMicroorganisms present in the vagina can influence host-related physiological processes, resident flora can prevent or hinder many urinary tract and sexually transmitted diseases [2,3]. Dysbiosis of vaginal microbes (VM), on the other hand, decreases cervicovaginal barrier function [4], increases adhesion, invasion and colonization by abnormal flora, alters metabolic profile and is associated with increased risk of inflammation, human papilloma virus (HPV) infection, premature birth,  \nmiscarriage and even gynecological cancers [5].  \nThere is also a strong correlation between gut microbes (GM) and gynecologic diseases. GM can regulate the estrogenic enterohepatic cycle [6], which affects target organs such as the breast and cervix [7]. There is increasing evidence that GM also play an important role in cervical carcinogenesis, participating in tumorigenesis, treatment, and prognosis. GM may also indirectly influence cervical carcinogenesis by affecting VM. First of all, the gut may be the origin of ","cbCaimJ72p6Ab1UE","https://ap.wps.com/l/cbCaimJ72p6Ab1UE","pdf",5245634,"English","# Keywords\n## Objective\n## Methods\n## Results\n## Conclusion\n# Introduction","[{\"question\":\"What study aims to determine about cervical cancer?\",\"answer\":\"The study investigates how vaginal and gut microbial communities change during cervical carcinogenesis and evaluates the auxiliary diagnostic value of these changes.
