The expression of B-cell lymphoma 2 (Bcl-2)-like protein 15 (BCL2L15) in endometrial epithelial cells (EECs) under progesterone (P4), estradiol (E2), and interferon-tau (IFN-τ) treatments. (A) EECs were treated with or without hormones, followed by treatment with or without IFN-τ for 12 h, then collected for real-time quantitative PCR analysis. (B) EECs were treated with or without hormones, followed by treatment with or without IFN-τ for 3, 6, and 12 h, then collected for Western blotting. (C) The silencing efficiency of the BCL2L15 was measured in the EECs. The negative control short hairpin RNA (shRNA) and pCD513B-U6-BCL2L15-shRNA were transduced for 48 h. (D) Fluorescence microscope images of BCL2L15 expression in EECs. Scale bar = 100 μm. The data are presented as the means ± S.E.M. of three independent experiments. ** Significant difference (p < 0.01) compared with other groups.
