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

The ability of pulmonary surfactant to reduce alveolar surface tension requires adequate levels of surfactant protein B (SP-B). Dexamethasone (DEX) increases human SP-B expression, in part, through increased SP-B mRNA stability. A 30-nt-long hairpin element (RBE) in the 3'-untranslated region of human SP-B mRNA mediates both DEX-induced and intrinsic mRNA stabilities, but the mechanism is unknown. Proteomic analysis of RBE-interacting proteins identified a primate-specific protein, RNA-binding motif X-linked-like-3 (RBMXL3). siRNA directed against RBMXL3 reduces DEX-induced SP-B mRNA expression in human bronchoalveolar cells. Human SP-B mRNA stability, measured by our dual cistronic plasmid assay, is unaffected by DEX in mouse lung epithelial cells lacking RBMXL3, but DEX increases human SP-B mRNA stability when RBMXL3 is expressed and requires the RBE. In the absence of DEX, RBE interacts with cellular proteins, reducing intrinsic SP-B mRNA stability in human and mouse lung epithelial cells. RBMXL3 specifically binds the RBE in vitro, whereas RNA immunoprecipitation and affinity chromatography analyses indicate that binding is enhanced in the presence of DEX. These results describe a model where intrinsic stability of human SP-B mRNA is reduced through binding of cellular mRNA decay factors to RBE, which is then relieved through DEX-enhanced binding of primate-specific RBMXL3.
