Mir-365 (Microrna): Potnetial Biomarker In Oral Squamous Cell Carcinoma Exosomes And Extracellular Vesicles, Jeffery Coon, Karl Kingsley, Katherine M. Howard
Dental Medicine Faculty Publications
Introduction: miR-365 is a non-coding microRNA that regulates transcription and has been demonstrated to promote oncogenesis and metastasis in some cancers, while suppressing these effects in others. Many microRNAs are produced and then exported extracellularly in exosomes, which are small extracellular vesicles ranging from 30 to 100 nm that are found in eukaryotic fluids and facilitate many cellular functions. Exosomes and extracellular vesicles are produced by many cell types, including oral cancer cells—although no study to date has evaluated miR-365 and oral cancer exosomes or extracellular vesicles. Based on this information, our research question was to evaluate whether oral cancers …
