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

Therapeutic protein overexpression can overwhelm endoplasmic reticulum (ER) folding capacity, trigger unfolded protein response (UPR) signaling, and compromise the safety of gene and mRNA therapies. Here, we engineer stress-responsive RNA rheostats that couple transgene expression to endogenous ER stress sensing. Short RNA elements derived from X-box-binding protein 1 (XBP1) mRNA undergo inositol-requiring enzyme 1α (IRE1α)-dependent splicing under ER stress, inducing a frameshift that attenuates downstream protein expression. XBP1 switches function across DNA and mRNA delivery platforms and regulate the expression of fluorescent reporters, coagulation factor VIII, and Leronlimab, a therapeutic anti-CCR5 monoclonal antibody. Switch activation reduces ER stress markers while preserving expression under homeostatic conditions. We further demonstrate the regulation of Leronlimab expression in vivo using recombinant adeno-associated virus vectors. Together, these findings establish programmable RNA feedback control as a strategy for linking cellular proteostasis to therapeutic protein expression and improving the safety of gene and mRNA therapies.
