Abstract

The authors determined the effect of cyclic guanosine 3′,5′-monophosphate (cGMP) on hydrogen peroxide (H₂O₂)-induced barrier dysfunction in bovine lung microvascular endothelial cell (BLMVEC) monolayers and compared the results to bovine pulmonary artery endothelial cells (BPAECs). In BLMVECs, H₂O₂ (250 μM) caused a 31.9% ± 4.8% decrease in transendothelial electrical resistance (TER) associated with increased actin stress fiber formation, intercellular gaps, and intracellular calcium concentration ([Ca²⁺]_i). The cGMP analogue 8-(p-chlorophenylthio)-cGMP (8p-CPT-cGMP; 30 or 50 μM) prevented the H₂O₂-induced decrease in TER (p < .001) as well as the cytoskeletal rearrangement and intercellular gap formation. 8-pCPT-cGMP (50 μM) attenuated the peak (418.8 ± 42.1 versus 665.2 ± 38.0 nmol/L; p < .001) and eliminated the sustained increase in [Ca²⁺]_i (193.5 ± 21.3 versus 418.8 ± 42.1 nmol/L; p < .001) caused by H₂O₂. 8-pCPT-cGMP also increased TER (14.2% ± 2.2%; p < .05) and decreased [Ca²⁺]_i (201.2 ± 12.5 vs. 214.4 ± 12.1 nmol/L; p < .03) before H₂O₂. In BPAECs, 8p-CPT-cGMP significantly attenuated H₂O₂-induced increases in permeability and [C²⁺]_i but less effectively than in BLMVECs. These results suggest that in BLMVECs, cGMP countered the adverse effects of H₂O₂ on barrier function by preventing actin cytoskeletal rearrangement and attenuating the increase in [Ca²⁺]_i.
