Figure 7: Changes in deamination activity after dFdU pretreatment in CDA-transfected COS-1 cells. (A) Pretreatment with dFdU before gemcitabine treatment resulted in decreased dFdU formation (n=3). (B) CDA transfection in COS-1 cells was confirmed by Western blot. Values that statistically significant differ from controls are presented.
