A. NSCLC cells were treated with the indicated concentrations of pemetrexed and sildenafil for 24h. Cells were isolated and viability determined by trypan blue exclusion assay (n = 3 +/− SEM) # p < 0.05 greater than corresponding value in vehicle treated cells. B. NSCLC cells were treated with the indicated concentrations of pemetrexed and sildenafil for 24h. Cells were isolated and viability determined by trypan blue exclusion assay (n = 3 +/− SEM) # p < 0.05 greater than corresponding value in pemetrexed treated cells.
