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

While adriamycin (adr) offers improvement in survival for breast cancer (BCa) patients, unfortunately, drug resistance is almost inevitable. Mounting evidence suggests that exosomes act as a vehicle for genetic cargo and constantly shuttle biologically active molecules including microRNAs (miRNAs) between heterogeneous populations of tumor cells, engendering a resistance-promoting niche for cancer progression. Our recent study showed that exosomes from docetaxel-resistance BCa cells could modulate chemosensitivity by delivering miRNAs. Herein, we expand on our previous finding and explore the relevance of exosome-mediated miRNA delivery in resistance transmission of adr-resistant BCa sublines. We now demonstrated the selective packing of miRNAs within the exosomes (A/exo) derived from adr-resistant BCa cells. The highly expressed miRNAs in A/exo were significantly increased in recipient fluorescent sensitive cells (GFP-S) after A/exo incorporation. Gene ontology analysis of predicted targets showed that the top 30 most abundant miRNAs in A/exo were involved in crucial biological processes. Moreover, A/exo not only loaded miRNAs for its production and release but also carried miRNAs associated with Wnt signaling pathway. Furthermore, A/exo co-culture assays indicated that miRNA-containing A/exo was able to increase the overall resistance of GFP-S to adr exposure and regulate gene levels in GFP-S. Our results reinforce our earlier reports that adr-resistant BCa cells could manipulate a more deleterious microenvironment and transmit resistance capacity through altering gene expressions in sensitive cells by transferring specific miRNAs contained within exosomes.
