Acute effects of acrolein exposure.

<p>Western blot analysis of active cleaved caspase 3 (<b>A</b>), caspase 12 (<b>B</b>) and VEGF (<b>C</b>) in whole lung tissue homogenates. WB bands were normalized to beta-actin. **P<0.01; *P<0.05 when compared to a control group. Rats received a single i.p. injection of acrolein at 12 µmol/kg and were sacrificed 1, 2, 4 or 24 hours after the challenge. n = 4 animals per group, data are mean±S.E.
