Detection of mRNA of Telomerase Protein in Benign Naevi and Melanomas Using RNAscope

Telomerase is reactivated in most cancers and is possibly an early driver event in melanoma. Our aim was to test a novel in situ hybridization technique, RNAscope, for the detection of human telomerase reverse transcriptase (hTERT) mRNA in archival formalin-fixed, paraffin-embedded (FFPE) tissue and to compare the mRNA expression of melanomas and benign naevi. Furthermore, we wanted to see if hTERT mRNA could be a diagnostic or prognostic marker of melanoma. In situ hybridization for the detection of hTERT mRNA was performed on FFPE tissue of 17 melanomas and 13 benign naevi. We found a significant difference in the expression of hTERT mRNA between melanomas and benign naevi (P
