1 · What the graph read from it

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.

2 · The registry

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

objectiveWhile the effects of biomechanical signals in the form of joint movement and exercise are known to be beneficial to inflamed joints, limited information is available regarding the intracellular mechanisms of their actions. This study was undertaken to examine the intracellular mechanisms by which biomechanical signals suppress proinflammatory gene induction by the interleukin-1-beta (IL-1beta)-induced NF-kappaB signaling cascade in articular chondrocytes.

methodsPrimary rat articular chondrocytes were exposed to biomechanical signals in the form of cyclic tensile strain, and the effects on the NF-kappaB signaling cascade were examined by Western blot analysis, real-time polymerase chain reaction, and immunofluorescence.

resultsCyclic tensile strain rapidly inhibited the IL-1beta-induced nuclear translocation of NF-kappaB, but not its IL-1beta-induced phosphorylation at serine 276 and serine 536, which are necessary for its transactivation and transcriptional efficacy, respectively. Examination of upstream events revealed that cyclic tensile strain also inhibited the cytoplasmic protein degradation of IkappaBbeta and IkappaBalpha, as well as repressed their gene transcription. Additionally, cyclic tensile strain induced a rapid nuclear translocation of IkappaBalpha to potentially prevent NF-kappaB binding to DNA. Furthermore, the inhibition of IL-1beta-induced degradation of IkappaB by cyclic tensile strain was mediated by down-regulation of IkappaB kinase activity.

conclusionThese results indicate that the signals generated by cyclic tensile strain act at multiple sites within the NF-kappaB signaling cascade to inhibit IL-1beta-induced proinflammatory gene induction. Taken together, these findings provide insight into how biomechanical signals regulate and reduce inflammation, and underscore their potential in enhancing the ability of chondrocytes to curb inflammation in diseased joints.
