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

Candida albicans is an important human fungal pathogen but its study has been hampered for being a natural diploid that lacks a complete sexual cycle. Gene knock-out and essential gene repression are used to study gene function in C. albicans. To effectively study essential genes in wild-type C. albicans, we took advantage of the compatible effects of the antibiotics hygromycin B and nourseothricin, the recyclable CaSAT1-flipper and the tetracycline-repressible (Tet-off) system. To allow deleting two alleles simultaneously, we created a cassette with a C. albicans HygB resistance gene (CaHygB) flanked with the FLP recombinase target sites that can be operated alongside the CaSAT1-flipper. Additionally, to enable conditionally switching off essential genes, we created a CaHygB-based Tet-off cassette that consisted of the CaTDH3 promoter, which is used for the constitutive expression of the tetracycline-regulated transactivator and a tetracycline response operator. To validate the new systems, all strains were constructed based on the wild-type strain and selected by the two dominant selectable markers, CaHygB and CaSAT1. The C. albicans general transcriptional activator CaGCN4 and its negative regulator CaPCL5 genes were targeted for gene deletion, and the essential cyclin-dependent kinase CaPHO85 gene was placed under the Tet-off system. Cagcn4, Capcl5, the conditional Tet-off CaPHO85 mutants, and mutants bearing two out of the three mutations were generated. By subjecting the mutants to various stress conditions, the functional relationship of the genes was revealed. This new system can efficiently delete genes and conditionally switch off essential genes in wild-type C. albicans to assess functional interaction between genes.
