RETRACTION NOTICE
AJAS wishes to retract the article “Induction of Ski Protein Expression upon Luteinization in Rat Granulosa Cells” published in the AJAS Vol 25, issue 5, page 635-641(2012), which is based on inadequate validation of primary data sources and data misrepresentation. The review was conducted by ethical committee of the AJAS following an admission of scientific misconduct by the first author (Hyun Kim, PhD) in relation to the data included in other studies (1 and 2). This review resulted in our decision to retract the aforementioned article.
1. Kim H, Yamanouchi K, Nishihara M. Expression of ski in the granulosa cells of atretic follicles in the rat ovary. J Reprod Dev 52: 715-721 (2006)
2. Kim H, Yamanouchi K, Matsuwaki T, Nishihara M. Induction of Ski protein expression upon luteinization in rat granulosa cells without a change in its mRNA expression. J Reprod Dev 58: 254-259 (2012)
（注意 - 2016.1.14加筆
1,2の共著者山内啓太郎氏によると,1,2に不正はない。Kim氏以外の東大の研究者（山内氏や共著者）は不正を行ったのではなく告発した側である。
撤回公告の「an admission of scientific misconduct by the first author (Hyun Kim, PhD) in relation to the data included in other studies (1 and 2). 」という部分は表現が適切でない又は誤りである。
当ブログは学術誌が撤回公告で「an admission of scientific misconduct by the first author (Hyun Kim, PhD) in relation to the data included in other studies (1 and 2). 」と公式公表したことを受けて、1,2の研究不正を公式に公告したと判断しました。関係者にはご迷惑をおかけし申し訳ありませんでした。）

撤回理由は「inadequate validation of primary data sources and data misrepresentation」だから、改ざんに該当するのだろう。
また、Hyun Kimが筆頭著者を務める別の2論文も撤回された。
