Direct repeat region 3' end modifications regulate Cas12a activity and expand its applications.
Article in Nucleic acids research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
CRISPR-Cas12a technology has transformative potential, but as its applications grow, enhancing its inherent functionalities is essential to meet diverse demands. Here, we reveal a regulatory mechanism for LbCas12a through direct repeat (DR) region 3' end modifications and de-modifications, which can regulate LbCas12a's cis- and trans-cleavage activities. We extensively explored the effects of introducing phosphorylation, DNA, photo-cleavable linker, DNA modifications at the DR 3' end on LbCas12a's functionality. We find that the temporary inhibitory function of Cas12a can be reactivated by DR 3' end modification corresponding substances, such as alkaline phosphatase (ALP), immunoglobulin G (IgG), alpha-fetoprotein (AFP), DNA exonucleases, ultraviolet radiation, and DNA glycosylases, which greatly expand the scope of application of Cas12a. Clinical applications demonstrated promising results in ALP, AFP, and trace Epstein-Barr virus detection compared to gold standard methods. Our research provides valuable insights into regulating LbCas12a activity through direct modification of DR and significantly expands its potential clinical detection targets, paving the way for future universal clustered regularly interspaced short palindromic repeats (CRISPR) diagnostic strategies.
