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.
