Role of CD14 and TLR4 in type I, type III collagen expression, synthesis and secretion in LPS-induced normal human skin fibroblasts.

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
objectivesThe primary aim of this study was to investigate the role of CD14 and TLR4 in type I, type III collagen expression, synthesis and secretion in LPS-induced normal human skin fibroblasts. The secondary aim was to provide theoretical basis for the molecular mechanisms of scar formation induced by LPS.
methodsThe normal skin fibroblasts cultured in vitro were randomly divided into four groups: 0.1 μg/mL LPS reference group, CD14 pretreatment + LPS, TLR4 pretreatment + LPS, CD14 and TLR4 pretreatment + LPS. The collagen DNA synthesis was assessed by (3)H-proline incorporation method. Real-time Quantitative PCR was used to detect type I, type III collagen mRNA expression.
resultsSimilar results were revealed for mRNA expression levels. The immunofluorescence staining suggested that type I and type III collagen were expressed in all investigated groups and that the expression was differentially downregulated in groups B, C, D. ELISA demonstrated markedly decreased levels in secreting type I, type III collagens and hydroxyproline in groups B, C, D (P<0.05), and the lowest level was detected in group D (P<0.01).
conclusionPretreatment with CD14 or TLR4 alone or their combination can significantly reduce the levels of type I and type III collagen expression, synthesis and secretion, with the most notable reduction detected in case of CD14 and TLR4 combined. We could thus conclude that both CD14 and TLR4 are involved in type I and type III collagen expression, synthesis and secretion in LPS-induced skin fibroblasts.
