Investigation of human equilibrative nucleoside transporter\u20101 (HENT\u20101) and deoxycytidine kinase (DCK), genes involved in gemcitabine uptake and metabolism, can be beneficial in the selection of potential cancer patients who could be responding to the treatment.<\/jats:p><\/jats:sec><jats:sec><jats:title>Aim<\/jats:title><jats:p>To study HENT\u20101 and DCK gene expression in HCC patients with different protocols of treatment.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Using real\u2010time PCR, we analyzed expression levels of HENT\u20101 and DCK genes from peripheral blood samples of 109 patients (20 controls &amp; 89 HCC patients) between March 2015 and March 2017.
