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

Penicillium oxalicum is a filamentous fungus widely recognized for its robust production of cellulases. It features complex pathways that govern the triggered expression of these enzymes. Signal transduction serves a critical function in the effective management of cellulase induction and expression. In this investigation, we conducted a screening to identify Pocdc42, a signaling protein found within the Ras signaling pathway of P. oxalicum. The knockout of Pocdc42 resulted in increased cellulase activity in P. oxalicum, along with significantly elevated expression levels of cellulase genes. Moreover, the disruption of Pocdc42 profoundly influenced the growth and development of the strain. The Pocdc42-deficient mutant demonstrated a significant reduction in its ability to produce conidia. The relative transcriptional activities of transcription factors BrlA and StuA, which are associated with conidiation, were 3.6- and 1.9-fold higher in the wild-type strain than in the mutant strain, respectively. In contrast, the gene expression of the transcription factor FlbC remained relatively stable. These results suggest that Pocdc42 is essential for the regulation of cellulase expression, as well as for hyphal growth, development, and conidium formation in P. oxalicum. The results of this study contribute to elucidating the mechanisms underlying the function of the Ras signaling pathway in the regulation of cellulase expression and growth and development in filamentous fungi.
