Hence, it needs to identify always new putative markers to improve its diagnosis and prognosis. The selenium is an essential trace mineral implicated as a key factor in the early stage of cancer and exerts its biological function through the selenoproteins. In the last years our group has been studying the involvement of some selenoproteins in HCC. However, no many data are reported in literature about the correlation between HCC and the glutathione peroxidases (GPXs), both selenium and non selenium-containing GPXs. In this paper we have evaluated the <em>GPX4</em> and <em>GPX7</em> expression in some paraffin-embedded tissues from liver biopsy of patients with hepatitis C virus (HCV)-related cirrhosis and HCC by immunohistochemistry and RT-qPCR analysis. Our results evidenced that i) <em>GPX4</em> and <em>GPX7</em> had a statistically significant over-expression in HCC tissues compared to cirrhotic counterparts used as non tumor tissues, and ii) their expression was higher in grade III HCC tissues with respect to grade I-II samples. Therefore, we propose to use <em>GPX4</em> and <em>GPX7</em> as possible markers for improving HCC diagnosis/prognosis.</p>}, number={4}, journal={European Journal of Histochemistry}, author={Guerriero, E. and Capone, F. and Accardo, M. and Sorice, A. and Costantini, M. and Colonna, G. and Castello, G. and Costantini, S.}, year={2015}, month={Dec.} }
