Abstract

In our study we present chosen elements of microarray analysis of gene expression profile in papillary thyroid cancer. The study group included 16 papillary thyroid cancer tissues and 16 corresponding normal tissues. Samples were analyzed on high density oligonucleotide microarrays (GeneChip HG-U133A) which contain 22.000 genes. 110 genes, which had significant changed expression, were selected by MAS 5.0 program. 3 genes were chosen to the deeper analysis: dipeptidylpeptidase 4 (DPP4), fibronectin 1 (FN1), tissue inhibitor of metalloproteinase 1 (TIMP1). DPP4-RNA were absent in normal tissue while in cancer tissue it was detected in large amount. FN1 and TIMP1 expression were detected in normal tissue but markedly increased in papillary thyroid cancer. Among these 3 genes DPP4 seems to be the best molecular marker for papillary thyroid cancer.
