miR-365 (microRNA): Potential Biomarker in Oral Squamous Cell Carcinoma Exosomes and Extracellular Vesicles
Introduction: miR-365 is a non-coding microRNA that regulates transcription and have been shown to promote metastasis in oncogenes and some types of cancer, while suppressing the effect on others. Many microRNAs is produced and then exported extracellular in exosomes, the small extracellular vesicles ranging from 30 to 100 nm are found in eukaryotic fluid and facilitate various cellular functions.
Exosomes and extracellular vesicles produced by many types of cells, including cancer cells mouth-though no study to date has evaluated miR-365 and oral cancer exosomes or extracellular vesicles. Based on this information, the question of our research is to evaluate whether the cancer of the mouth produces extracellular exosomes or vesicles containing miR-365.
Materials and methods: Two commercially available oral cancer cell lines (SCC25 and CAL27) and normal oral keratinocytes (OKF4) were grown in serum-free media, supplemented with exosome-depleted fetal bovine serum. extracellular vesicles and exosomes then isolated using Invitrogen Total exosome RNA and protein isolation kit for processing using HSA-miR-365a-5p microRNA qPCR assay kits.
Results: RNA was isolated from exosome-depleted supernatant from each cell line-SCC9, SCC15, SCC25, and CAL27 (oral squamous cell carcinoma) and OKF4 (oral epithelial cell lines). the relative concentration of RNA were similar among each cell line, which is not significant, p = 0.233. RNA quality was established by A260: A280 absorbance using a NanoDrop, expressing the purity ranging from 1.73 to 1.86. Expression of miR-16 microRNA is used to confirm the presence of exosomes extracted and extracellular vesicles. The presence of miR-365 was later confirmed and normalized to miR-16 expression, which indicates the rate of increase of miR-365 in both CAL27 and SCC25. In addition, the normalization relative quantity (RQ) for miR-365 exhibited a greater variation between SCC25 (1.382 to 4.363) of cells CAL27 (1.248 to 1.536).
Conclusion: These results confirm that miR-365 was not only expressed in cancer cell lines of the mouth, but also subsequently exported to exosomes and extracellular vesicles derived from this culture. This data can help to contextualize this microRNA potential to contribute to the phenotype and behavior of oral cancers that express this microRNA. Future research will begin to investigate the potential mechanisms and pathways and to determine whether miR-365 may be useful as a biomarker of cancer of the mouth for saliva or fluid biopsy.
Exosomal Circulating microRNAs as potential novel biomarker detection in pancreatic cancer
Circulating microRNAs exosomal (ex-miRNA) is reflective of the characteristics of the tumor and valuable biomarkers in a variety of tumor types. In addition, miRNAs serve an important role in tumor progression and metastasis.
This study aims to determine the outstanding ex-miRNA-21 and miRNA-210 as a new biomarker for patients with pancreatic cancer (PC). For this purpose, the former serum miRNAs extracted from the serum of patients with PC (n = 30) and chronic pancreatitis (CP) (n = 10) using the RNA isolation kit.
