Novel role of PE_PGRS47 in the alteration of mycobacterial cell wall integrity and drug resistance.
Article in Archives of microbiology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
The proline-glutamic acid and proline-proline-glutamic acid (PE/PPE) family of proteins is widespread in pathogenic mycobacteria and plays different roles in mycobacterial physiology. While several PE/PPE family proteins have been studied, the exact function of most PE/PPE proteins in the physiology of Mycobacterium tuberculosis (Mtb) remains unknown. PE_PGRS47 belongs to the PE/PPE family of proteins reported to help Mtb evade protective host immune responses. In this study, we demonstrate a novel role of PE_PGRS47. Heterologous expression of the pe_pgrs47 gene in a non-pathogenic Mycobacterium smegmatis, intrinsically deficient of PE_PGRS protein, exhibits modulated colony morphology and cell wall lipid profile leading to a marked susceptibility to multiple antibiotics and environmental stressors. Using ethidium bromide/Nile red uptake assays, Mycobacterium smegmatis expressing PE_PGRS47 showed higher cell wall permeability than the control strain. Overall, these data suggested that PE_PGRS47 is cell surface exposed and influences cell wall integrity and the formation of mycobacterial colonies, ultimately potentiating the efficacy of lethal stresses against mycobacteria.
