Titration of SF3B1 Activity Reveals Distinct Effects on the Transcriptome and Cell Physiology.
Article in International journal of molecular sciences, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
SF3B1 is a core component of the U2 spliceosome that is frequently mutated in cancer. We have previously shown that titrating the activity of SF3B1, using the inhibitor pladienolide B (PB), affects distinct steps of the heat shock response (HSR). Here, we identify other genes that are sensitive to different levels of SF3B1 (5 vs. 100 nM PB) using RNA sequencing. Significant changes to mRNA splicing were identified at both low PB and high PB concentrations. Changes in expression were also identified in the absence of alternative splicing, suggesting that SF3B1 influences other gene expression pathways. Surprisingly, gene expression changes identified in low PB are not predictive of changes in high PB. Specific pathways were identified with differential sensitivity to PB concentration, including nonsense-mediated decay and protein-folding homeostasis, both of which were validated using independent reporter constructs. Strikingly, cells exposed to low PB displayed enhanced protein-folding capacity relative to untreated cells. These data reveal that the transcriptome is exquisitely sensitive to SF3B1 and suggests that the activity of SF3B1 is finely regulated to coordinate mRNA splicing, gene expression and cellular physiology.
