The antitumor effect of the toll-like receptor 3 ligand polyinosinic-cytidylic acid as an adjuvant.

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
Although polyinosinic-polycytidylic acid (poly(I:C)) has been applied in tumor immunity as a Toll-like receptor 3 (TLR3) ligand, the interaction between poly(I:C) and TLR3 is still unclear, as are the mechanisms underlying the antitumor effect of poly(I:C). Our aim was to investigate the interaction between poly(I:C) and TLR3, as well as the mechanisms underlying the antitumor effect of poly(I:C). NK92 cells were maintained in medium (untreated group), or medium containing E7(44-62) (E7 group) or E7(44-62)+poly(I:C) (poly(I:C)/E7 group), and we measured the expression of TLR3 mRNA, p-p65, and IκB-α protein. The cells were first incubated in medium alone or medium containing TLR3 monoclonal antibody, and then in medium containing poly(I:C)/E7. Finally, we measured the level of interferon-beta (INF-β) in the supernatant and determined the tumor cell-killing effect of the NK92 cells. At 1 h, the expression of TLR3 mRNA in the poly(I:C)/E7 group was markedly higher than that in the untreated and E7 groups (P < 0.05). When compared with the poly(I:C)/E7 group, the expression of IκB-α was dramatically increased in the E7 and untreated groups, and the expression of p-p65 was dramatically decreased in the E7 and untreated groups (all P < 0.05). At 24 h, INF-β content and tumor cell-killing activity in the poly(I:C)/E7 group were markedly higher than those in the untreated group (P < 0.001, <0.05, respectively). Treatment with TLR3 monoclonal antibody significantly inhibited poly(I:C)/E7-induced INF-β secretion and tumor cell-killing activity in NK92 cells (P < 0.001, <0.05, respectively). The interaction between poly(I:C) and TLR3 plays an important role in the antitumor immunity of NK92 cells. In addition, the interaction between poly(I:C) and TLR3 increases INF-β expression, which may be attributed to the activation of NFκB.
