Global Assessment of Protein Translation in Mammalian Cells Using Polysome Fractionation.

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
A character of active protein translation is formation of multiple ribosomes, or polysomes, on translating mRNAs. Polysome intensity reflects global cellular translation activity and can be assessed after biochemical fractionations of polysomes. Polysome fractionation begins with immobilizing ribosomes on mRNAs using inhibitors of translation elongation, for example, cycloheximide. Nuclei-free cell lysates are then isolated and layered on the top of a sucrose gradient for ultracentrifugation to separate ribosomal subunits, monosome, and multiple fractions of polysomes by their different sedimentation rates along the sucrose gradient. A density gradient fractionation system including a spectrophotometer reads the RNA absorbance of the flowed gradient and generates the fractions. These fractions can be subjected to further RNA and protein analyses, for example, polysome profiling and mass spectrometry. Here, we present a detailed protocol of polysome fractionation for mammalian cells.
