Please note that this is a peculiar case of retraction, since while there are indeed problems with certain images, the authors stated the following in the retraction notice: "Nevertheless, although we feel that the scientific conclusions of the paper (that loss of NNT impairs insulin secretion and impairs glucose tolerance in C57BL/6J mice) still stand, given the conclusion of scientific misconduct against the first author, the authors think the most responsible course is to retract the paper." It is important to understand that nuance especially in view that thousands of publications state that they used "C57BL6" without making a crucial distinction between C57BL/6J and C57BL/6N.
