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

Accumulating evidence showed that microRNA-152 (miR-152) was frequently downregulated, and functioned as tumor suppressor in many cancers, but little is known about its biological role and intrinsic regulatory mechanisms in colorectal cancer (CRC). Here, we explored the potential role of miR-152 in CRC and the possible molecular mechanisms. Our results proved that miR-152 expression was downregulated in CRC cell lines and tissue samples, and its expression was inversely correlated with advanced tumor-node-metastasis (TNM) stage (P < 0.01) and lymph node metastasis (P < 0.01). Function assays demonstrated that restoring the expression of miR-152 in CRC cells dramatically reduced the cell proliferation and cell migration and invasion and promoted apoptosis and caspase-3 activity in vitro, as well as suppressed tumor growth in vivo. Mechanistic investigations defined phosphoinositide-3-kinase regulatory subunit 3 (PIK3R3) as a direct and functional downstream target of miR-152. In addition, we also found that PIK3R3 expression was upregulated and was inversely correlated with miR-152 expression in clinical CRC tissues. Downregulation of PIK3R3 mimicked the tumor-suppressive effects of miR-152 overexpression in CRC cells. Taken together, these results elucidated the function of miR-152 in CRC progression and suggested that miR-152 might function as tumor suppressor in CRC by targeting PIK3R3.
