Abstract

Abstract miRNAs are small non-coding RNA molecules, involved in the regulation of gene expression via binding to messenger RNA (mRNA), thereby preventing protein translation. We found that the promotor region of miR-193a is highly methylated in FaDu head and neck cancer cells, assuming that its expression is suppressed. Moreover, our results indicated that miRNA-193a levels are undetectable in biopsies of head and neck cancer patients. Induction of miR-193a expression by treatment with methyltransferase inhibitor or transduction of head and neck squamous cell carcinoma (HNSCC) cells with miR-193a resulted in a significant decrease in cell viability in a dose and time-dependent manners, as well as induction of apoptosis through the caspase intrinsic pathway. Moreover, miR-193a also inhibited tumour growth in xenograft mice transplanted with FaDu cells. In addition, we found that miR-193a inactivates the AKT/mTOR signaling pathway through the downregulation of PIK3R3, mTOR, S6KB2, and ERBB4. These observations suggest that miR-193a plays an important role in tumor biogenesis and therefore has the potential to serve for diagnostics as well as therapeutics in HNSCC.

Moreover, miR-193a also inhibited tumour growth in xenograft mice transplanted with FaDu cells. In addition, we found that miR-193a inactivates the AKT/mTOR signaling pathway through the downregulation of PIK3R3, mTOR, S6KB2, and ERBB4. These observations suggest that miR-193a plays an important role in tumor biogenesis and therefore has the potential to serve for diagnostics as well as therapeutics in HNSCC.","manuscriptTitle":"miRNA-193a acts as a tumor suppressor in human head and neck cancer cells and inhibits tumor development in xenograft mice","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2024-06-10 22:22:40","doi":"10.21203/rs.3.rs-4310591/v1","editorialEvents":[{"type":"communityComments","content":0}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"researchsquare","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":true,"externalIdentity":"","sideBox":"","snPcode":"","submissionUrl":"/submission","title":"Research Square","twitterHandle":"researchsquare","acdcEnabled":true,"dfaEnabled":false,"editorialSystem":"","reportingPortfolio":"","inReviewEnabled":false,"inReviewRevisionsEnabled":true}}],"origin":"","ownerIdentity":"347b97b3-e417-4496-8aa6-3b476f8668e4","owner":[],"postedDate":"June 10th, 2024","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"posted","subjectAreas":[{"id":32355511,"name":"Biological sciences/Cancer"},{"id":32355512,"name":"Biological sciences/Cancer/Cancer therapy/Targeted therapies"},{"id":32355513,"name":"Health sciences/Biomarkers/Diagnostic markers"}],"tags":[],"updatedAt":"2024-06-27T08:45:24+00:00","versionOfRecord":[],"versionCreatedAt":"2024-06-10 22:22:40","video":"","vorDoi":"","vorDoiUrl":"","workflowStages":[]},"version":"v1","identity":"rs-4310591","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-4310591","identity":"rs-4310591","version":["v1"]},"buildId":"qtupq5eGEP_6zYnWcrvyt","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
