1 · What the graph read from it

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.

2 · The registry

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

Signal recognition particle (SRP) recognizes signal sequences of secretory proteins and targets them to the endoplasmic reticulum membrane for translocation. Many human diseases are connected with defects in signal sequences. The current dogma states that the molecular basis of the disease-associated mutations in the secretory proteins is connected with defects in their transport. Here, we demonstrate for several secretory proteins with disease-associated mutations that the molecular mechanism is different from the dogma. Positively charged or helix-breaking mutations in the signal sequence hydrophobic core prevent synthesis of the aberrant proteins and lead to degradation of their mRNAs. The degree of mRNA depletion depends on the location and severity of the mutation in the signal sequence and correlates with inhibition of SRP interaction. Thus, SRP protects secretory protein mRNAs from degradation. The data demonstrate that if disease-associated mutations obstruct SRP interaction, they lead to silencing of the mutated protein expression.
