Research Abstract |
Gemcitabine (GEM here-in after) is the best chemotherapeutic agent to patients with pancreatic cancer to date. However, patients often acquire resistance to GEM. In order to overcome this acquired chemo-resistance, we performed molecular analyses and identified DCK as the key molecule for acquired resistance; (1) high frequency of inactivating mutation in acquired cancer cells, (2) introduction of DCK to resistant cells recovered chemo-sensitivity to GEM, and (3) knockdown of DCK in parental cells acquired chemo-resistance. These results demonstrate that inactivating mutation of DCK is one of the key alterations for acquisition of GEM resistance.
