  sub:_4 prov:value "Treatment with retinoic acid itself (from 1010 to 106 M) did not alter the viability of BEAS-2B cells (Figure 2A), A549 cells (Figure 2B), or primary cultures of HTE cells (Figure 2C) for 24 h. However, retinoic acid inhibited decreases in cell viability induced by elastase in BEAS-2B cells (0.06 U/ml of elastase) (Figure 2D), A549 cells (0.3 U/ml of elastase) (Figure 2E), and HTE cells (3 U/ml of elastase) (Figure 2F)." ;
