In Vitro Assay to Measure APE1 Enzymatic Activity on Ribose Monophosphate Abasic Site.
Article in Methods in molecular biology (Clifton, N.J.), 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
APE1 (apurinic/apyrimidinic endodeoxyribonuclease 1) is a central enzyme of the base excision repair (BER) pathway playing a pivotal role in protecting mammalian cells against genotoxins and in safeguarding genome stability. Recently, we demonstrated the APE1 ability to process abasic ribonucleotides embedded in DNA. Here, we provide a pipeline of protocols to quantify endodeoxyribonuclease activity by APE1 on these substrates, by using recombinant protein and whole-cell extracts. The repair capacity is measured by using fluorescent oligonucleotide substrates, which are then separated by polyacrylamide gel electrophoresis and detected by imaging scanning. The specificity of APE1 action is demonstrated using specific APE1 enzymatic inhibitors.
