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

Colon cancer is a widespread life-threatening malignancy with complex and multifactorial etiology. Both epidemiological cohort studies and basic research support the substantial role of iron metabolism in colon cancer. Thus, understanding the mechanisms of how essential iron metabolic proteins are dysregulated may provide new treatment strategies for colon cancer. Ferritin is the main iron storage protein that occupies a vital position in iron metabolism. Studies reported that ferritin is differentially highly expressed in tissues from multiple malignancies. However, the source and function of highly expressed ferritin in colon cancer have not been explored. In this study, we found that the protein level but not RNA level of ferritin heavy chain (FTH1) was upregulated in colon cancer using paired clinical samples. Co-culture system was used to mimic the in vivo circumstance and study the cell-cell communication of macrophages and colon cancer cells. Results showed that M2 macrophages could substantially increase the FTH1 levels in colon cancer cells. This effect could be blocked by the exosome biogenesis/ secretion inhibitor GW4869, implying the vital role of exosomes in this biological process. Besides, we found that purified exosomes from M2 macrophages could deliver FTH1 into colon cancer cells and promote cell proliferation. Furtherly, EdU assay and live cell imaging system were performed in FTH1-OE (overexpression) colon cancer cell lines and confirmed the cell proliferation promoting effect of FTH1. Our results unveil the source and function of highly expressed FTH1 in colon cancer and provide a new potential therapeutic target for the treatment of colon cancer.
