Novel cis-active structures in the coding region mediate CRM1-dependent nuclear export of IFN-α 1 mRNA.
Article in Medical molecular morphology, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
We recently reported the chromosome region maintenance 1 (CRM1)-dependent nuclear export of intron-less human interferon-α1 (IFN-α1) mRNA, which encodes a main effecter of host innate immunity. We show that the coding region of IFN-α1 mRNA forms novel secondary structures that are responsible for the CRM1-dependent export of the transcript. Deletion-mutagenesis, in vivo export assays, and computer analyses of the folding potentials of export-competent fragments revealed the presence of a domain, termed the conserved secondary structure (CSS), comprising two adjacent putative stable stem-loop structures (nt 208-452). Internal deletion-mutagenesis and constitutive export assays of each stem-loop structure demonstrated that subregions 308-322 and 352-434 act as a core element by conferring the export function on the CSS. Leptomycin B (LMB) inhibition of the CRM1 pathway decreased the export of core element RNA, implying that the principal site of CRM1 action for exporting IFN-α1 mRNA resides within the core element. An RNPS1 (RNA-binding protein S1, serine-rich domain) cDNA was isolated by yeast three-hybrid screening, using bait containing two CSS regions. We showed that RNPS1 might recognize IFN-α1 mRNP that includes CRM1. The data demonstrate that interaction between RNA structures in the coding region and CRM1 affects the nucleocytoplasmic translocation of IFN-α1 mRNA.
