Increased immunoreactivity for Jun- and Fos-related proteins in Alzheimer's disease: association with pathology
Anderson AJ, Cummings BJ, Cotman CW.. Experimental neurology, 1994-02-01
Topic: Amyloid, tau and blood-test diagnosis
The protein products of the Jun and Fos immediate early gene (IEG) families are cooperative transcriptional regulatory factors implicated in regulating the expression of many genes. The levels of a variety of proteins such as the amyloid precursor protein and basic fibroblast growth factor are altered in Alzheimer's disease (AD), thus the events regulating these changes are of interest. Both of these genes contain an activator protein-1 consensus sequence which may be responsive to regulation by immediate early genes. In order to evaluate the potential involvement of IEGs in AD pathology, we have examined Jun- and Fos-related protein immunoreactivity in control and AD brain. Specifically, we investigated the correspondence of immunoreactivity for Jun and Fos proteins with immunoreactivity for paired helical filament-1 (PHF-1), a marker for neurofibrillary tangles which recognizes abnormally phosphorylated tau, glial fibrillary acidic protein (GFAP), and thioflavine staining in double-labeling experiments. An intensification of both Jun and Fos immunoreactivity was observed in AD cases; in addition, both Jun and Fos immunoreactivity were colocalized with PHF-1 in some neurons in AD brain. Jun and Fos immunoreactivity were also colocalized with GFAP-positive astrocytes distributed in the cortex of AD and control cases, and surrounding thioflavine-stained plaques in AD brain. These observations suggest that members of the Jun and Fos IEG families may play a role in AD pathology.

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 randomised / 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 multi-centre collaboration, so those were left out: it earned 21 of the 58 points we could judge it on, which is 36 out of 100.
