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 prenylation of several proteins involved in oncogenesis and signal transduction plays an essential role in regulating their biological activities. Two distinct isoprenoids are known to be involved in this modification, the 15-carbon farnesyl and 20-carbon geranylgeranyl groups. Thus far, identified farnesylated proteins contain methionine or serine at the COOH terminus, while those modified by geranylgeranyl end in leucine. This report describes the characterization of an enzyme activity that transfers the geranylgeranyl group to candidate proteins. The enzyme, termed a "protein geranylgeranyltransferase," exhibits a marked preference for substrate proteins that contain leucine at the COOH terminus. In fact, the enzyme will efficiently modify a normally farnesylated protein, Ha-ras, if its COOH-terminal amino acid is switched from serine to leucine. Additional studies characterize this enzyme and suggest that it is responsible for the geranylgeranyl modification of a number of GTP-binding proteins (or their subunits) that contain a consensus prenylation sequence ending in leucine.
