Knockout of the longevity gene Klotho perturbs aging- and Alzheimer's disease-linked brain microRNAs and tRNA fragments.
Article in bioRxiv : the preprint server for biology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Overexpression of the longevity gene Klotho prolongs, while its knockout shortens lifespan and impairs cognition via altered fibroblast growth factor signaling that perturbs myelination and synapse formation; however, comprehensive analysis of Klotho's knockout consequences on mammalian brain transcriptomics is lacking. Here, we report the altered levels under Klotho knockout of 1059 long RNAs, 27 microRNAs (miRs) and 6 tRNA fragments (tRFs), reflecting effects upon aging and cognition. Perturbed transcripts included key neuronal and glial pathway regulators that are notably changed in murine models of aging and Alzheimer's Disease (AD) and in corresponding human post-mortem brain tissue. To seek cell type distributions of the affected short RNAs, we isolated and FACS-sorted neurons and microglia from live human brain tissue, yielding detailed cell type-specific short RNA-seq datasets. Together, our findings revealed multiple Klotho deficiency-perturbed aging- and neurodegeneration-related long and short RNA transcripts in both neurons and glia from murine and human brain.
