Figure Lengend Snippet: Peptide P326TAT prevents both caspase-dependent and caspase-independent apoptosis of lung endothelial cells. PAECs were treated with peptide P326TAT (20 μm) or control peptide PlwTAT (20 μm) and exposed to hyperoxia for 48 h, after which caspase-3 activity and AIF protein level in the nuclear fraction were measured as described under “Experimental Procedures.” A, changes in caspase-3 activity. B, representative image of Western blot of AIF. WO peptide, without peptide. C, bar graph depicting changes in nuclear AIF levels of PAECs. Results are expressed as means ± S.E.; n = 4. *, p < 0.05 versus normoxia.
