microRNA expression in ulcerated primary cutaneous melanoma

microRNA expression in RNA isolated from formalin fixed, paraffin embedded tissue from ulcerated primary cutaneous melanoma compared to non-ulcerated primary cutaneous melanoma In this study microRNA and mRNA expression was assessed in formalin fixed, paraffin embedded melanoma tissue from primary, cutaneous lesions with (n=19) and without (n=16) histologically confirmed tumor ulceration using the Nanostring human miRNA assay and Nanostring human tumor signaling 360 mRNA assay, respectively.
