Gene signature of the post-Chernobyl papillary thyroid cancer

ABSTRACT: Thyroid gland is among the most sensitive organs to ionizing radiation. Whether low-dose radiation-induced papillary thyroid cancer (PTC) differs from sporadic PTC is yet unknown. We used microarrays to identify gene signature of radiation-induced papillary thyroid carcinomas To identify molecular differences between radiation-induced (Exposed to Chernobyl Radiation, ECR) and sporadic PTC, we investigated 65 childhood/young adult PTC samples using DNA microarray (Affymetrix, Human Genome U133 2.0 Plus). The PTC samples were from patients born either before (33 ECR cases) or at least 9 months after (32 non-ECR cases) the Chernobyl catastrophe. Multofactoral analyses were performed in order to define some additional factors that could have impact on the gene expression profile. Morover the m
