Measuring Poly-Adenosine Tail Length of RNAs by High-Resolution Northern Blotting Coupled with RNase H Cleavage.
Article in Methods in molecular biology (Clifton, N.J.), 2024. 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 poly-adenosine, or poly(A) tail, plays key roles in controlling the stability and translation of messenger RNAs in all eukaryotes, and, as such, facile assays that can measure poly(A) length are needed. This chapter describes an approach that couples RNase H-mediated cleavage of an RNA of interest with high-resolution denaturing gel electrophoresis and northern blot-based detection. Major advantages of this method include the ability to directly measure the abundance of any RNA and the length of its poly(A) tail without amplification steps. The assay provides high specificity, sensitivity, and reproducibility for accurate quantitation using standard molecular biology equipment and reagents. Overall, the high-resolution northern blotting approach offers a cost-effective means of poly(A) RNA analysis that is especially useful for small numbers of transcripts and comparisons between experimental conditions or time points.
