Characterization of the melanoma miRNAome by deep sequencing

ABSTRACT: MicroRNAs are 18-23 nucleotide non-coding RNAs that regulate gene expression in a sequence specific manner. Little is known about the repertoire and function of miRNAs in melanoma or the melanocytic lineage. We therefore undertook a comprehensive analysis of the miRNAome in a diverse range of pigment cells including: melanoblasts, melanocytes, congenital nevocytes, acral, mucosal, cutaneous and uveal melanoma cells. We sequenced 12 small RNA libraries using Illumina's GAII platform. This massively parallel sequencing approach revealed a total of 539 known mature and mature-star sequences, along with the prediction of 389 novel miRNA candidates. Using the relative proportion of the total unique read counts against total number of reads, hierarchal clustering of all novel candidates plus kno
