Measuring Spatiotemporal cAMP Dynamics Within an Endogenous Signaling Compartment Using FluoSTEP-ICUE.
Article in Methods in molecular biology (Clifton, N.J.), 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
cAMP is a ubiquitous second messenger involved in the regulation of diverse cellular processes. Spatiotemporal regulation of cAMP through compartmentalization within various subcellular microdomains is essential to ensure specific signaling. In the following protocol, we describe a method for directly visualizing signaling dynamics within cAMP microdomains using fluorescent sensors targeted to endogenous proteins (FluoSTEPs). Instead of overexpressing a biosensor-tagged protein of interest to target a microdomain, FluoSTEP Indicator of cAMP using Epac (FluoSTEP-ICUE) utilizes spontaneously complementing split GFP and CRISPR-Cas9 genome editing to localize a FRET-based cAMP biosensor to an endogenously expressed protein of interest. Utilizing this approach, FluoSTEP-ICUE can be used to measure cAMP levels within endogenous signaling compartments, thus providing a powerful tool for studying the spatiotemporal regulation of cAMP signaling.
