GSK3 and tau: two convergence points in Alzheimer's disease
Hernandez F, Lucas JJ, Avila J.. Journal of Alzheimer's disease : JAD, 2013-01-01
Topic: Disease mechanisms in lab and animal studies
Glycogen synthase kinase 3 (GSK3) is a ubiquitously expressed serine/threonine kinase that plays a key role in the pathogenesis of Alzheimer's disease (AD). GSK3 phosphorylates tau in most serine and threonine residues hyperphosphorylated in paired helical filaments, and GSK3 activity contributes both to amyloid-β production and amyloid-β-mediated neuronal death. Thus, mice generated in our laboratory with conditional overexpression of GSK3 in forebrain neurons (Tet/GSK3β mice) recapitulate aspects of AD neuropathology such as tau hyperphosphorylation, apoptotic neuronal death, and reactive astrocytosis, as well as spatial learning deficit. In this review, we describe recent contributions of our group showing that transgene shutdown in that animal model leads to normal GSK3 activity, normal phospho-tau levels, diminished neuronal death, and suppression of the cognitive deficit, thus further supporting the potential of GSK3 inhibitors for AD therapeutics. In addition, we have combined transgenic mice overexpressing the enzyme GSK3β with transgenic mice expressing tau with a triple FTDP-17 mutation that develop prefibrillar tau-aggregates. Our data suggest that progression of the tauopathy can be prevented by administration of lithium when the first signs of neuropathology appear. Further, it is possible to partially reverse tau pathology in advanced stages of the disease, although the presence of already assembled neurofibrillary tangle-like structures cannot be reversed.

How this study scored 36/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomized / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multicenter collaboration, so those were left out: it earned 21 of the 58 points we could judge it on, which is 36 out of 100.
