Fig. 7From: The alveolar epithelial cells are involved in pulmonary vascular remodeling and constriction of hypoxic pulmonary hypertensionEffect of hypoxia on ROS in AECs. A Hypoxia significantly increased the intensity of ROS (a) and the content of H2O2 (b) in ATII and the content of H2O2 in ATII culture medium (c). (B) Hypoxia significantly increased SOD2 mRNA level (a), the total content of SOD (c) and the activity of SOD (d) of ATII, but has no significant effect on the CAT mRNA level (b). n = 3, Data are means ± S.D.
