Accurate Detection of Target MicroRNA in Mixed Species of High Sequence Homology Using Target-Protection Rolling Circle Amplification.

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 close relationships of miRNAs with human diseases highlight the urgent needs for miRNA detection. However, the accurate detection of a target miRNA in mixed miRNAs of high sequence homology presents a great challenge. Herein, a novel method called target-protection rolling circle amplification (TP-RCA) is proposed for this purpose. The protective probe is designed so that it can form a fully complementary duplex with the target miRNA and can also mismatch duplexes with other nontarget miRNAs. These duplexes are treated with a single strand-specific nuclease. Consequently, only the target miRNA in a perfect-match duplex can resist the cleavage of nuclease, whereas the nontarget miRNAs in mismatched duplexes will be digested completely. The protected target miRNA can be detected using RCA reactions. MicroRNA let-7 family members (let-7a-let-7f) and nuclease CEL I were used as proof-of-concept models to evaluate the feasibility of the TP-RCA method under different experimental conditions. The experimental results show that the TP-RCA method can unambiguously detect the target let-7 species in mixtures of let-7 family members even though they may differ by only a single nucleotide. This TP-RCA method significantly improves the detection specificity of miRNAs.
