Multicolor miRNA fluorescence in situ hybridization for tumor differential diagnosis


ABSTRACT: We profiled and quantitated miRNAs in two skin tumors (Basal cell carcinoma and Merkel cell carcinoma) and identified tumor-specific miRNAs. We used these tumor-specific miRNAs to guide development of miRNA fluorescence in situ hybridization. 2 barcoded sequencing runs, including 40 unique samples (36 used in manuscript). The details of each sample can be found in Supplementary Tables S1 and S2.

MicroRNAs (miRNAs) are excellent tumor biomarkers because of their cell-type specificity and abundance. However, many miRNA detection methods, such as real-time PCR, obliterate valuable visuospatial information in tissue samples. To enable miRNA visualization in formalin-fixed paraffin-embedded (FFPE) tissues, we developed multicolor miRNA FISH. As a proof of concept, we used this method to differentiate two skin tumors, basal cell carcinoma (BCC) and Merkel cell carcinoma (MCC), with overlappin  ...[more]
