Influence of DNA-repair gene variants on the micronucleus frequency in thyroid cancer patients.

The role of different DNA-repair genes (OGG1, XRCC1, XRCC2 and XRCC3) on both the spontaneous and the induced frequency of micronuclei (MN) has been studied in the lymphocytes of a group of 114 patients with differentiated thyroid cancer (DTC). Induction of MN was achieved by treatment of the lymphocytes with 0.5Gy of gamma-radiation. The selected genes are… CONTINUE READING
