  sub:_5 prov:value """Apoptosis is executed through the activation of caspases. To further verify the effect
of tobacco smoke in the induction of apoptosis, the levels of cleaved caspases
8, 9, and 3 in rat lungs were determined. In agreement with the apoptotic results
described above, exposure of rats to 80 mg/m3 tobacco smoke resulted in significantly
increased levels of cleaved caspases 8, 9, and 3, indicating the activation
of these caspases (Fig. 7B). Compared to FA control animals, the cleaved
caspases 8, 9, and 3 were elevated by 98.1%, 113.9%, and 84.7 %, respectively.""" ;
