Specific endonucleolytic cleavages of mouse albumin mRNA and their modulation during liver development.

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 have detected specific endonucleolytic cleavages of mouse albumin mRNA by S1 nuclease protection analysis of total RNA from fetal mouse liver using a cDNA probe spanning the middle, coding region of albumin mRNA. With the use of probe labeled at its 5' end, three prominent cleavages were detected which were confirmed and their endonucleolytic nature was established by further analysis using 3' end-labeled probe. The latter probe also revealed one more cleavage which was not detected with the 5' end-labeled probe. These cleavages mapped to positions on the mRNA which included a unique sequence motif CCAN1-3CUGN0-1UGAU. Degradation intermediates corresponding to these cleavages were consistently observed, specifically in fetal liver but not in normal or regenerating adult liver and appeared to have originated in vivo. Their levels decreased progressively from 18th day of gestation and became undetectable by 20 days after birth. No detectable changes in the levels of any of the prominent degradation products of alpha-fetoprotein (a homologue of albumin) mRNA could be observed during this period of development. Since accumulation of degradation intermediates is known to correlate with higher rate of mRNA turnover, our observations raise the possibility that the stability of albumin mRNA may be lower in fetal than in adult mouse liver.
