We would like to retract the article entitled “Nuclear import of prototype foamy virus transactivator Bel1 is mediated by KPNA1, KPNA6 and KPNA7” published in International Journal of Molecular Medicine 38: 339–406, 2016. The results presented in Fig. 6 have been demonstrated to be unreproducible, and we cannot provide an explanation for this. Furthermore, we have recently identified that the cell cultures used in our experiments were partly contaminated with Mycoplasma, which could have contributed to the irreproducibility of the results. In addition, we are currently in dispute with a colleague who has contributed towards this study, but does not wish to be included as a named author on the paper. We are therefore going to retract this article. All the authors unanimously agree to the retraction of this paper, and we deeply apologize to readers and editors for any inconvenience caused by this retraction.
