The Role of CTGF in Inflammatory Responses Induced by Silica Particles in Human Bronchial Epithelial Cells.

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
backgroundProlonged exposure to crystalline silica leads to persistent pulmonary inflammation and progressive fibrosis. Connective tissue growth factor (CTGF) has emerged as a potent proinflammatory and profibrotic regulator to participate in a variety of chronic inflammatory diseases. However, the role of CTGF in silica-induced pulmonary inflammation remains poorly understood.
methodsTo explore the effect of CTGF on inflammatory responses caused by silica particles, human bronchial epithelial cells (16HBE) were transfected with CTGF siRNA and exposed to silica particles at concentrations of 0, 12.5, 25, 50, 100 μg/ml for 48 h. Intracellular CTGF mRNA and protein expressions were determined by RT-PCR and Western blotting, respectively. The levels of inflammatory cytokines including IL-8, TNF-α, IL-6, IL-1β, IL-17A and TGF-β
resultsSilica particles induce significantly elevated intracellular CTGF mRNA expression in 16HBE cells in a dose-dependent manner when compared with blank control group (P < 0.05). The secretions of IL-8, TNF-α, IL-6 and IL-17A were also significantly increased by silica particles (P < 0.05). After exposure to 25 or 50 μg/ml silica particles, the expression of intracellular CTGF mRNA was significantly inhibited in 16HBE cells when transfected with CTGF siRNA (P < 0.05). The secreted levels of IL-8, TNF-α, IL-6 and IL-17A induced by silica particles were also significantly lower from CTGF siRNA-transfected cells than that from normal 16HBE cells (P < 0.05).
conclusionInhibition of CTGF gene attenuates silica-induced inflammatory responses in bronchial epithelial cells, suggesting that CTGF could be a pivotal regulator in the development of silica-induced inflammation.
