Identification and functional characterization of Candida albicans mannose-ethanolamine phosphotransferase (Mcd4p).
Article in Current genetics, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Glycosylphosphatidylinositol (GPI) is an important compound for the growth of fungi, because GPI-anchored proteins including glycosyltransferases and adhesins are involved in cell-wall integrity, adhesion, and nutrient uptake in this organism. In this study, we examined orf19.5244 in the genome database of the pathogenic fungus Candida albicans, a homologue of the Saccharomyces cerevisiae mannose-ethanolamine phosphotransferase gene, MCD4, which plays a role in GPI synthesis. Expression of this homologue, designated CaMCD4, restored cell growth in a defective conditional mcd4 mutant of S. cerevisiae, Scmcd4t, in which expression of native MCD4 was repressed in the presence of doxycycline (Dox). Analysis of radiolabeled lipids showed that the accumulation of abnormal GPI anchor precursors in Scmcd4t decreased markedly upon expression of CaMCD4. Moreover, we constructed a single mutant (Camcd4/CaMCD4) and a conditional double mutant (Camcd4/Camcd4t) at the MCD4 locus of C. albicans. Repression of CaMCD4 expression by Dox led to a decrease in growth and appearance of abnormal morphology in C. albicans, both in vitro and in a silkworm infection model. These results suggest that CaMcd4p is indispensable for growth of C. albicans both in vitro and in infected hosts and a candidate target for the development of new antifungals.
