Concomitant treatment with HU enhances sensitivity to FdU. Indicated cells were cultured in YES, normalised and serially diluted five times with YES. Five microliter of diluted fractions were spotted on rich media containing the indicated drugs and incubated at 32 °C for 3 days. Cells carrying TKanAX grew poorly in YES containing 5 mM HU and 100 μg/ml FdU
