Effect of apelin on oxidative stress in BeWo cells. The cells were treated with apelin at 2 and 20 ng/mL for 24 h, and the oxygen consumption assay was performed. Experiments were independently performed and repeated three times (n = 3). The data are arranged as means ± SEM. Different letters indicate significant differences (p < 0.05) among groups; Control (C).
