A comparative study of nuclear 8-hydroxyguanosine expression in Autoimmune Thyroid Diseases and Papillary Thyroid Carcinoma and its relationship with p53, Bcl-2 and Ki-67 cancer related proteins

Simultaneous “overexpression” of 8-OHdG and Bcl-2 in GD and HT could be considered as prognostic markers while “negligible expression” of Ki-67 in PTC lymphoid cells suggests an anergic state favoring the tumor escapes from the immune system.
