To this aim, we analysed by qRT-PCR the expression levels of both RP5-1024C24.1 and MPPED2 in a set of nine FTA samples, additional 12 PTC samples, six FTC and 12 ATC and compared them to the mean of three normal thyroid tissues (three out of the four normal thyroid samples used for microarray hybridization and validation, see Materials and Methods section). This evidence concerns the gene MPPED2 and thyroid cancer, nonmedullary, 2.
