  sub:_2 prov:value "we utilized NCI-H1299 NSCLC cell lines engineered to express shRNA targeting either cdk2 or cdk1 upon doxycycline induction (Cai et al., 2006b) and assessed the degree of S-phase cell-cycle arrest after exposure to cisplatin or IR in the absence or presence of doxycycline. In the absence of doxycycline in both sets of cells, cisplatin treatment for 24 hr caused cells to accumulate in S phase (Figure 1A and see Figure S1 available online)." ;
