Retraction Note: Progesterone induces apoptosis by activation of caspase-8 and calcitriol via activation of caspase-9 pathways in ovarian and endometrial cancer cells in vitro (Apoptosis, (2021), 26, 3-4, (184-194), 10.1007/s10495-021-01657-1)

The Editors-in-Chief have retracted this article. After the publication of the article, concerns have been raised regarding image overlaps in Fig. 3A, B with images from previously published articles [1, 2]. An investigation report by Uniformed Services University found the below concerns. Reused HCV + FFA ß-actin lanes of Fig. 5A of [11 was relabeled as IETD-FMK TOV-21G ß- actin lanes in Fig. 3A. Reused ß-actin lanes of Fig. 7A of [1] was relabeled as IETD-FMK ß-actin lanes in Fig. 3A. Falsified ß-actin lanes for {}ES-2 LY294002 of Fig. 4B, lanes 1–4 of [2] was reused as Z-LEHD-FMK HED 59 ß-actin lanes in Fig. 3B. Reused HCV + FFA ß-actin lanes of Fig. 5A of [11 was relabeled as IETD-FMK TOV-21G ß- actin lanes in Fig. 3A. Reused ß-actin lanes of Fig. 7A of [1] was relabeled as IETD-FMK ß-actin lanes in Fig. 3A. Falsified ß-actin lanes for {}ES-2 LY294002 of Fig. 4B, lanes 1–4 of [2] was reused as Z-LEHD-FMK HED 59 ß-actin lanes in Fig. 3B. The Editors-in-Chief therefore have lost confidence in the results and conclusions presented in this article. Author, G. Larry Maxwell agrees to this retraction. Authors, Latoya McGlorthan, Ana Paucarmayta, and Yovanni Casablanca have not responded to any correspondence from the editor/publisher about this retraction.
