Figure 4. Effects of NAC and CGK733 on CS and mTOR. (A) HT-p21-9 cells were plated at 40000 per well in 96 well plates with indicated agents: 500 nM rapamycin (R), 5-20 mM NAC and incubated for 6 days. On Day 6 replicative viability of cells was measured by colony formation (8 days) as described in legend for Figure
