Expression of TLR7, TLR9, JAK2, and STAT3 genes in peripheral blood mononuclear cells from patients with systemic sclerosis.
Article in Journal of applied genetics, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Systemic sclerosis (SSc) is a rare, chronic, multisystem autoimmune disease clinically characterized by progressive fibrosis of the skin and internal organs. The basic mechanism appears to involve endothelial cell injury, overproduction of extracellular matrix proteins, and aberrant immune activation. So far, there have been a few attempts to find genetic biomarkers for monitoring disease activity or for correlation with certain symptoms. In order to reveal reliable biomarkers, we analyzed the expression of four genes representing three important signaling pathways, TLR7, TLR9, and JAK2-STAT3. Using RT-qPCR technique, we analyzed the expression of TLR7, TLR9, JAK2, and STAT3 genes in peripheral blood mononuclear cells of 50 SSc patients and 13 healthy individuals. We detected significant upregulation of TLR7 gene expression in a group of SSc patients compared to non-SSc group. Receiver operating characteristic (ROC) analysis showed that TLR7 expression efficiently discriminates SSc cases from healthy individuals. High TLR7 expression positively correlated with the late form of disease, active SSc, and the presence of digital ulcers. Decreased levels of TLR9 and JAK2 mRNA were found in the patient's cohort in comparison to non-SSc individuals, but showed no correlation with specific clinical outcomes. The expression level of the STAT3 gene did not differ between the analyzed groups. This is the first study on the expression of TLR7, TLR9, and STAT3 genes in SSc patients. Our results show that TLR7, TLR9, and JAK2 genes are potential biomarkers for SSc. The results obtained in this study could contribute to better classification, monitoring, and outcome prediction of patients with SSc based on genetics.
