Identification of Differentially Expressed Genes in Nocardia brasiliensis Induced by Progesterone and Dihydrotestosterone Using Differential Display PCR.
Article in Current microbiology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Sex steroid hormones have an important physiological role in humans. They can also affect the gene expression of many organisms, including bacteria. In Mexico, Nocardia brasiliensis is the main causative agent of actinomycetoma, a granulomatous disease more frequent in men than women, which is thought to be related to a higher occupational risk in men. Therefore, it has been suggested that differences in clinical presentation could be related to sex steroid hormone levels. Attempting to explain the differences in actinomycetoma prevalence between men and women, in this work, the effect of progesterone and dihydrotestosterone on the genetic expression of N. brasiliensis was investigated using a differential display polymerase chain reaction assay. The results showed that both hormones affected the expression of genes encoding proteins related to central metabolism and hypothetical proteins with unknown functions. This study also demonstrated the utility of differential display in this modern era and provided a first approach to the effect of sex hormones on N. brasiliensis gene expression.
