"A-kinase" regulator runs amok to provide a paradigm shift in cAMP signaling.
Article in The Journal of biological chemistry, 2019. 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
The activity of the archetypal protein kinase A (PKA) is typically thought of in regards to the catalytic subunit, which is inhibited by the regulatory subunits in the absence of cAMP. However, it is now reported that one of the regulatory subunit isoforms (PKA-RIα) takes on a function of its own upon binding to cAMP, acting independently of this canonical cAMP signaling mechanism. PKA-RIα instead binds to and stimulates the catalytic activity of a guanine nucleotide exchange factor (P-REX1) that itself promotes Rac1 GTPase activation. This newly discovered function of PKA-RIα adds an additional layer of complexity to our understanding of cAMP signal transduction.
