SSUP-72/PINN-1 coordinates RNA-polymerase II 3' pausing and developmental gene expression in C. elegans.

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
During exit from Caenorhabditis elegans (C. elegans) L1 developmental arrest, a network of growth- and developmental genes is activated, many of which are organized into operons where transcriptional termination is uncoupled from mRNA 3'-end processing. CDK-12-mediated Pol II CTD S2 phosphorylation enhances SL2 trans-splicing at downstream operonic genes, preventing premature termination and ensuring proper gene expression for developmental progression. Using a genetic screen, we identified the SSUP-72/PINN-1 module as a suppressor of defects induced by CDK-12 inhibition. Loss of SSUP-72/PINN-1 bypasses the requirement for CDK-12 in post-embryonic development. Genome-wide analyses reveal that SSUP-72, a CTD S5P phosphatase, affects Pol II 3' pausing and regulates intra-operon termination. Our findings establish SSUP-72/PINN-1 as a key regulator of Pol II dynamics, coordinating operonic gene expression and growth during C. elegans post-embryonic development.
