1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Alzheimer's disease (AD) is a devastating, progressive neurodegenerative disorder that leads to severe cognitive impairment in elderly patients. Chronic neuroinflammation plays an important role in the AD pathogenesis. Glia maturation factor (GMF), a proinflammatory molecule discovered in our laboratory, is significantly upregulated in various regions of AD brains. We have previously reported that GMF is predominantly expressed in the reactive glial cells surrounding the amyloid plaques (APs) in the mouse and human AD brain. Microglia are the major source of proinflammatory cytokines and chemokines including GMF. Recently clustered regularly interspaced short palindromic repeats (CRISPR) based genome editing has been recognized to study the functions of genes that are implicated in various diseases. Here, we investigated if CRISPR-Cas9-mediated GMF gene editing leads to inhibition of GMF expression and suppression of microglial activation. Confocal microscopy of murine BV2 microglial cell line transduced with an adeno-associated virus (AAV) coexpressing Staphylococcus aureus (Sa) Cas9 and a GMF-specific guide RNA (GMF-sgRNA) revealed few cells expressing SaCas9 while lacking GMF expression, thereby confirming successful GMF gene editing. To further improve GMF gene editing efficiency, we developed lentiviral vectors (LVs) expressing either Streptococcus pyogenes (Sp) Cas9 or GMF-sgRNAs. BV2 cells cotransduced with LVs expressing SpCas9 and GMF-sgRNAs revealed reduced GMF expression and the presence of indels in the exons 2 and 3 of the GMF coding sequence. Lipopolysaccharide (LPS) treatment of GMF-edited cells led to reduced microglial activation as shown by reduced p38 MAPK phosphorylation. We believe that targeted in vivo GMF gene editing has a significant potential for developing a unique and novel AD therapy.
