MS2-MBP-Based Affinity Purification of Nucleus- or Cytoplasm-Localized lncRNA-Protein Complexes Formed In Vivo.
Article in Methods in molecular biology (Clifton, N.J.), 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
With recent emergence of huge number of long noncoding RNAs (lncRNAs), purification of lncRNA-protein (lncRNP) complexes is fundamental to understand the role of lncRNA and its biological function. However, lncRNP purification is still a daunting challenge. Here we describe a protocol to purify lncRNP formed in vivo with MS2-MBP-based affinity purification. Inducible lncRNA tagged with MS2 RNA hairpins is introduced into cells of interest, and RNP on tagged lncRNA is formed in vivo. MS2-MBP fusion protein is expressed in Escherichia coli and purified with amylose resin and HiTrap heparin column. The MS2 part of MS2-MBP fusion protein binds to the hairpins, and MBP part binds to amylose resin. We also describe a protocol to separate the nucleus and the cytoplasm so that lncRNP localized in the nucleus or cytoplasm can be individually purified. The amount of lncRNP purified is well sufficient for mass spectrometry analysis.
