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

Our recent evidence showed that prior expansion of CCR6(+) Foxp3(+) regulatory T cells (Tregs) was important for their dominant enrichment in tumor tissue, which was closely related to poor prognosis of breast cancer patients. However, the underlying regulation mechanism of expansion of CCR6(+) Tregs in situ remains largely unknown. In this study, we reported that miR-21 was highly expressed in CCR6(+) Tregs in tumor tissues from a murine breast cancer model. And silencing of miR-21 could significantly reduce the proliferation of CCR6(+) Tregs in vitro. Adoptive cell-transfer assay further showed that silencing of miR-21 could alter the enrichment of CCR6(+) Tregs in the tumor mass and endow effectively antitumor effect of CD8(+) T cells using a murine breast cancer model. Mechanistic evidence showed that silencing of miR-21 enhanced the expression of its target phosphatase and tensin homolog deleted on chromosome ten (PTEN) and subsequently altered the activation of Akt pathway, which was ultimately responsible for reduced proliferation activity of CCR6(+) Tregs. Finally, we further revealed that miR-21 was also highly expressed on CCR6(+) Tregs in clinical breast cancer patients. Therefore, miR-21 can act as a fine tuner in the regulation of PTEN/Akt pathway transduction in the expansion of CCR6(+) Tregs in tumor sites and provided a novel insight into the development of therapeutic strategies for promoting T-cell immunity by regulating distinct subset of Tregs through targeting specific miRNAs.
