A biochemistry study has been retracted nearly a year after a whistleblower found significant overlap between the article and one published in a different journal by the same research group.
The study, “Berberine ameliorates renal injury in diabetic C57BL/6 mice: Involvement of suppression of SphK–S1P signaling pathway,” appeared in the journal Archives of Biochemistry and Biophysics in July 2010. It has been cited 76 times.
The study examines how berberine, a compound found in plants such as tree turmeric, might improve kidney injury in diabetic mice. People sometimes take berberine supplements to help treat diabetes, but the evidence for its effectiveness is mixed. The authors of the paper are researchers at Sun Yat-sen University in Guangzhou, China.
The study was retracted on May 23 at the request of the journal’s editor-in-chief, according to the retraction notice. It states, in part:
