The Role of Cross-Pathway Control Regulator CpcA in the Growth and Extracellular Enzyme Production of Penicillium oxalicum.

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
CpcA is a conserved transcriptional activator for the cross-pathway control of amino acid biosynthetic genes in filamentous fungi. Previous studies of this regulator mainly revealed its function under amino acid starvation condition, where amino acid biosynthetic inhibitors were added in the culture. In this study, the biological function of CpcA in Penicillium oxalicum was investigated under different cultivation conditions. Disruption of cpcA led to decreased cell growth either in the presence or absence of histidine biosynthetic inhibitor, and the phenotype could be rescued by the addition of exogenous amino acid sources. In addition, CpcA was required for the rapid production of cellulase when cells were cultured on cellulose. Transcript abundance measurement showed that a set of amino acid biosynthetic genes as well as two major cellulase genes were significantly down-regulated in cpcA deletion mutant relative to wild type. Taken together, the results revealed the biological role of CpcA in supporting normal growth and extracellular enzyme production of P. oxalicum under amino acid non-starvation condition.
