Project description:We performed microRNA sequencing of primary human FFPE Acral Melanoma (AM), Cutaneous Melanoma (CM), Acral Nevi (AN), and Cutaneous Nevi (CN). We found that previously identified ratios of microRNAs, particularly miR-21-5p and miR-211-5p, were able to accurately classify benign and malignant melanocytic neoplasia, both in non-acral cutaneous melanomas and nevi (CM vs CN), as well as matched acral melanoma and nevi (AM vs AN). Receiver operating characteristic area under the curve (AUC) of Ensemble models trained using these microRNA ratios demonstrated AUCs of 0.88-0.90 across these melanoma subtypes, suggesting the potential utility of these ratios as a biomarker of malignancy in melanocytic neoplasia.
Project description:Genotyping of a matched normal, primary and metastatic acral melanoma DNA from blood and one matched Primary and one metastatic acral melanoma was genotyped on Affmetrix SNP6
