Harnessing noncanonical trans-cleavage characteristics of Cas12 and Cas13a to enhance CRISPR-based diagnostics.
Article in Communications biology, 2024. 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
Cas12 and Cas13 are extensively utilized in molecular diagnostics for their trans-cleavage activities, yet their activation characteristics remain partially understood. Here, we conduct an in-depth investigation of Cas12a, Cas12f1, and Cas13a, uncovering the characteristics of their trans-DNase and trans-RNase activities with noncanonical activators. Our findings reveal that DNA can serve as a direct target for CRISPR-Cas13a, markedly increasing the detection sensitivity for single-base mismatches. Moreover, the trans-cleavage activities of Cas12a and Cas13a can be activated by diverse RNA:DNA and RNA:RNA duplexes, respectively, indicating that the presence of stem-loop structures in crRNAs is not essential for their activation. Notably, Cas12f1, unlike Cas12a, exhibits intrinsic RNase activity independently of activation. Leveraging these insights, we have improved the accuracy of a dual-gene target detection approach that employs the CRISPR-Cas12f1 and Cas13a systems. Our research advances the understanding of the noncanonical activation characteristics of Cas12 and Cas13a, contributing to the field of CRISPR-based diagnostics.
