Cell retraction of Alzheimer’s study is second for Tufts neuroscientist

A researcher at Tufts University has retracted a paper in Cell, a year after retracting a study on a similar subject from the Journal of Biological Chemistry. Here’s the notice for “SIRT1 Suppresses β-Amyloid Production by Activating the α-Secretase Gene ADAM10,” a 2010 paper by Tufts’ Gizem Donmez, MIT’s Leonard Guarante — of longevity research … Continue reading Cell retraction of Alzheimer’s study is second for Tufts neuroscientist

Authors withdraw already-corrected JBC paper questioned on PubPeer

An assistant professor of neuroscience at Tufts has withdrawn a paper published last year after one round of corrections wasn’t enough to fix all of the study’s problems. The study, “Sirtuin 2 (SIRT2) enhances 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced nigrostriatal damage via deacetylating forkhead box O3a (Foxo3a) and activating Bim protein,” by Gizem Donmez and colleagues, had already … Continue reading Authors withdraw already-corrected JBC paper questioned on PubPeer
