Structural and functional analysis of an mRNP complex that mediates the high stability of human beta-globin mRNA.

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
Human globins are encoded by mRNAs exhibiting high stabilities in transcriptionally silenced erythrocyte progenitors. Unlike alpha-globin mRNA, whose stability is enhanced by assembly of a specific messenger RNP (mRNP) alpha complex on its 3' untranslated region (UTR), neither the structure(s) nor the mechanism(s) that effects the high-level stability of human beta-globin mRNA has been identified. The present work describes an mRNP complex assembling on the 3' UTR of the beta-globin mRNA that exhibits many of the properties of the stability-enhancing alpha complex. The beta-globin mRNP complex is shown to contain one or more factors homologous to alphaCP, a 39-kDa RNA-binding protein that is integral to alpha-complex assembly. Sequence analysis implicates a specific 14-nucleotide pyrimidine-rich track within its 3' UTR as the site of beta-globin mRNP assembly. The importance of this track to mRNA stability is subsequently verified in vivo using mice expressing human beta-globin transgenes that contain informative mutations in this region. In combination, the in vitro and in vivo analyses indicate that the high stabilities of the alpha- and beta-globin mRNAs are maintained through related mRNP complexes that may share a common regulatory pathway.
