1 · What the graph read from it

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.

2 · The registry

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

The regulation of neuropeptide gene expression has been investigated by using rat adrenal medullae grown in explant culture. After 3 days in culture the (now denervated) explants exhibited a 10-fold increase in leucine-enkephalin (leu-EK) content. Inhibition of protein synthesis with cycloheximide completely blocked the rise, whereas inhibition of RNA synthesis with actinomycin D or alpha-amanitin inhibited the increase by 50%. Inhibition of DNA synthesis with 1-beta-D-arabinofuranosylcytosine (cytosine arabinoside) had no discernible effect. To determine whether the rise in leu-EK was associated with an increase in specific mRNA coding for the opiate peptide precursor, blot hybridization analysis was performed. A single species of preproenkephalin mRNA was detected after various culture periods. The amount of mRNA increased 34-fold after 2 days in culture and 74-fold after 4 days. Consequently, the rise in mRNA levels preceded the increase in the amount of leu-EK. Depolarization of the adrenal medullae with either elevated potassium or veratridine, which prevents leu-EK accumulation, inhibited the increase in the amount of preproenkephalin mRNA. Moreover, the effect of veratridine was blocked by tetrodotoxin, suggesting that transmembrane sodium ion influx affects the increase in the amount of message. Our studies suggest that elevation of leu-EK in explanted (denervated) medullae is associated with increased amounts of mRNA coding for the peptide precursor and that these processes can be regulated by depolarization.
