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

delta 1-pyrroline-5-carboxylate reductase (P5CR; [L-proline: NAD(P+) 5-oxidoreductase]; EC 1.5.1.2) catalyzes the final step in proline biosynthesis. We have shown that the proline-1 (pro-1) locus of Neurospora crassa encodes P5CR. The pro-1 gene was localized to a 3.2 kb region by complementation of (restoration of proline-independent growth to) a proline auxotroph carrying a recessive mutation at the pro-1 locus. The nucleotide sequence of this 3.2 kb region contains an open reading frame with coding capacity of 311 amino acids. The deduced polypeptide shows significant similarity to P5CR amino acid sequences. Similarity of N. crassa P5CR is greatest to that of the yeast, Saccharomyces cerevisiae, but is also strong to P5CR sequences from archaea, eubacteria, plants, and humans. In N. crassa, amino acid imbalance, including deficiency or excess of a single amino acid, such as histidine, induces expression of many amino acid biosynthetic genes that are under cross-pathway control, a general regulatory system analogous to general amino acid control in Saccharomyces. Although P5CR catalyzes the only committed step in proline biosynthesis, pro-1 expression was unaltered by histidine starvation and independent of CPC1, a positively acting transcription factor that mediates cross-pathway control in N. crassa.
