Effects of U1 Small Nuclear Ribonucleoprotein Inhibition on the Expression of Genes Involved in Alzheimer's Disease.
Article in ACS omega, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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
Deposition and dysfunction of U1 small nuclear ribonucleoprotein (snRNP) have been revealed in Alzheimer's disease (AD), but whether U1 is involved in the amyloid precursor protein (APP) and Tau pathways remains unclear. Here, we investigate this by inhibiting the U1 components in cultured cells and examining the expression changes of AD-related genes to these two canonic pathways. We find that knockdown of U1-70K and U1C increases the protein expressions of APP and GSK-3β while reduces that of Nicastrin in a dose-dependent manner. Knockdown of U1A shows no effects on the expression of these proteins. The real-time PCR results show that the mRNA expression levels of APP, Nicastrin and GSK-3β are unchanged, decreased, and increased, respectively. In addition, U1-70K knockdown suppresses Tau phosphorylation and causes altered splicing of Tau exon 10. This study suggests that the effect of U1 snRNP knockdown is component-specific and more likely involved in APP deregulation in AD.
