This being the JBC, the retraction notice for “Human T-cell Leukemia Virus Type I Tax Down-regulates the Expression of Phosphatidylinositol 3,4,5-Trisphosphate Inositol Phosphatases via the NF-κB Pathway” is the very definition of opaque:
This article has been withdrawn by the authors.
The paper has been cited 13 times, according to Thomson Scientific’s Web of Knowledge.
The corresponding author of the paper, Takashi Tsuji, appears to be a fairly prominent researcher. Last year, he and his colleagues published a study in PLoS ONE in which they showed how a tooth could be grown from stem cells. The paper garnered significant media attention. He also studies hair regeneration.
We’ve contacted Tsuji, and the JBC, for more information, and will update with anything we find out.
Update, 9:30 a.m. Eastern, 1/31/12: See this post for an explanation from Tsuji.
