MiRNA data from melanoma-derived exosomes and melanoma cell lines


ABSTRACT: Identify miRNAs enriched or overexpressed in melanoma-derived exosomes compared to melanoma cells. We analyzed the 2,578 human miRNAs located in the array according to two ways. The first one identified the differentially expressed miRNAs between melanoma-derived exosomes and their parent cells. In this way, we found 198 miRNAs up-regulated in melanoma cell lines compared to their exosomes and 206 miRNAs up-regulated in exosomes compared to their donor cells. The second way of analysis identifies the most expressed miRNAs in the melanoma-derived exosomes without assumption about their expression in parent cells. We defined two criteria; the first one is a RMA (Robust Multi-Array Average, a good alternative to gene expression value) above 5, corresponding to the mean expression level of the array and a SD ≤ 0.2 between all samples to discover miRNAs expressed uniformly between melanoma-derived exosomes M113 and M117. We identified 44 miRNAs under these criteria.
