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

Colorectal cancer (CRC) remains both common and fatal, and its successful treatment is greatly limited by the development of stem cell-like characteristics (stemness) and chemoresistance. MiR-30-5p has been shown to function as a tumor suppressor by targeting the Wnt/β-catenin signaling pathway, but its activity in CRC has never been assessed. We hypothesized that miR-30-5p exerts anti-oncogenic effects in CRC by regulating the USP22/Wnt/β-catenin signaling axis. In the present study, we demonstrate that tissues from CRC patients and human CRC cell lines show significantly decreased miR-30-5p family expression. After identifying the 3'UTR of USP22 as a potential binding site of miR-30-5p, we constructed a luciferase reporter containing the potential miR-30-5p binding site and measured the effects on USP22 expression. Western blot assays showed that miR-30-5p decreased USP22 protein expression in HEK293 and Caco2 CRC cells. To evaluate the effects of miR-30-5p on CRC cell stemness, we isolated CD133 + CRC cells (Caco2 and HCT15). We then determined that, while miR-30-5p is normally decreased in CD133 + CRC cells, miR-30-5p overexpression significantly reduces expression of stem cell markers CD133 and Sox2, sphere formation, and cell proliferation. Similarly, we found that miR-30-5p expression is normally reduced in 5-fluorouracil (5-FU) resistant CRC cells, whereas miR-30-5p overexpression in 5-FU resistant cells reduces sphere formation and cell viability. Inhibition of miR-30-5p reversed the process. Finally, we determined that miR-30-5p attenuates the expression of Wnt/β-catenin signaling target genes (Axin2 and MYC), Wnt luciferase activity, and β-catenin protein levels in CRC stem cells.
