Here’s the notice in Brain for “Intranasal insulin prevents cognitive decline, cerebral atrophy and white matter changes in murine type I diabetic encephalopathy:”
Since publication we, the authors, have become aware that portions of the data obtained at the University of Calgary and presented in this manuscript were manipulated and not represented properly, in particular, the immunohistochemistry images from Figs 4, 5 and 8, and the western blot and EMSA data in Fig. 8.
We regret our failure to detect these faulty data before the original manuscript was published, and apologize for any inconvenience that may have arisen as a result of our report.
This retraction is agreed by Cory Toth, George J. Francis, Jose A. Martinez, Jared Fine, Ursula I. Tuor, Leah R. Hanson and William H. Frey II. Unfortunately the following co-authors could not be contacted: Wei Q. Liu, Kevin Xu, Amit Ayer and Gordon Glazner.
