Increased expression of TLR-2, COX-2, and SOD-2 genes in the peripheral blood leukocytes of opisthorchiasis patients induced by Opisthorchis viverrini antigen.

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
Re-infection with liver fluke, Opisthorchis viverrini, increases proinflammatory molecules involved in inflammation-mediated disease and carcinogenesis in an animal model. To clarify whether these genes respond to parasite antigen in peripheral blood leukocytes (PBL) of opisthorchiasis patients, we examined the transcriptional level of oxidant-generating (toll-like receptor 2 (TLR-2), nuclear factor-kappa B (NF-KB), and cyclooxygenase 2 (COX-2)), anti-oxidant-generating (manganese superoxide dismutase 2 (SOD-2) and catalase (CAT)), proinflammatory cytokine (interleukin (IL)-1β), and anti-inflammatory cytokine (IL-10), in PBL exposed to parasite antigen in O. viverrini-infected patients compared with healthy individuals in an in vitro experiment. After O. viverrini antigen-treated PBL, quantitative RT-PCR analysis revealed that increased expression of cytokines and oxidant-generating genes in PBL was similar between O. viverrini-infected and healthy groups. Interestingly, compared with healthy subjects, increase of TLR-2, COX-2, and SOD-2 and decreased CAT mRNA expression levels were observed in O. viverrini-infected group. The results indicate that O. viverrini antigen induces upregulation of TLR-2, COX-2, and SOD-2 and downregulation of CAT genes in opisthorchiasis patients, suggesting that imbalance of oxidant/anti-oxidant transcripts during re-infection may be involved in the inflammatory-driven carcinogenesis. These molecules may be used as the chemopreventive target for intervention of opisthorchiasis patients in an endemic area.
