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 genome of the filamentous fungus Neurospora crassa contains a single gene encoding a heterotrimeric G-protein beta subunit, gnb-1. The predicted GNB-1 protein sequence is most identical to G beta proteins from the filamentous fungi Cryphonectria parasitica and Aspergillus nidulans. N. crassa GNB-1 is also 65% identical to the human GNB-1 protein but only 38 and 45% identical to G beta proteins from budding and fission yeasts. Previous studies in animal and fungal systems have elucidated phenotypes of G beta null mutants, but little is known about the effects of G beta loss on G alpha levels. In this study, we analyzed a gnb-1 deletion mutant for cellular phenotypes and levels of the three G alpha proteins. Delta gnb-1 strains are female-sterile, with production of aberrant fertilized reproductive structures. Delta gnb-1 strains conidiate more profusely and have altered mass on solid medium. Loss of gnb-1 leads to inappropriate conidiation and expression of a conidiation-specific gene during growth in submerged culture. Intracellular cyclic AMP levels are reduced by 60% in vegetative plate cultures of delta gnb-1 mutants. Loss of gnb-1 leads to lower levels of the three G alpha proteins under a variety of conditions. Analysis of transcript levels for the gna-1 and gna-2 G alpha genes in submerged cultures indicates that regulation of G alpha protein levels by gnb-1 is posttranscriptional. The results suggest that GNB-1 directly regulates apical extension rate and mass accumulation. In contrast, many other delta gnb-1 phenotypes, including female sterility and defective conidiation, can be explained by altered levels of the three N. crassa G alpha proteins.
