Hypoxia-reoxygenation effects on protein expression of bovine brain microvessel endothelial cells (BBMECs). Confluent monolayers were exposed to normoxia (C), 24-h hypoxia (H) or hypoxia with 2-h reoxygenation (HR). Representative Western blots for actin (42 kDa), claudin-1 (44 kDa dimer), occludin (65 kDa), ZO-1 (220 kDa), and ZO-2 (160 kDa) are shown (n = 4).
