Fig 3. Overexpression of Hsp70 protects against hyperoxia-induced lung endothelial barrier disruption.

PAECs were transduced with sham adenovirus or adenovirus containing Hsp70 gene. After incubation for 48 h, cells were then exposed to hyperoxia or normoxia for 60 h. TEER was continuously monitored as described in Materials and Methods. Results are expressed as mean ± SE; n = 3. * P<0.05 vs normoxia+sham virus.
