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

backgroundTumour-associated macrophages (TAMs) are the most abundant immune cells in the tumour environment and are considered similar to M2 macrophages, which facilitate cancer progression. Exosomes, as important mediators of the cross-talk between tumour cells and tumour-associated macrophages, can facilitate the development and metastasis of ovarian cancer by mediating M2 macrophage polarization. However, the exact mechanisms underlying the communication between ovarian cancer (OC) cells and tumour-associated macrophages during OC progression remain unclear.

resultsHere, we demonstrated that high expression of miR-205 was associated with M2 macrophage infiltration, which affected the prognosis of OC patients. Importantly, tumour-derived miR-205 could be transported from OC cells to macrophages via exosomes and promote cancer cell invasion and metastasis by inducing M2-like macrophage polarization. Animal experiments further confirmed that exosomal miR-205-induced M2 macrophages accelerated OC progression in vivo. Mechanistically, miR-205 downregulated PTEN, activating the PI3K/AKT/mTOR signalling pathway, which is critical for M2 polarization.

conclusionsThese results reveal that exosomal miR-205 plays a pivotal role in macrophage polarization within the OC microenvironment, highlighting its potential as a therapeutic target for OC treatment. This study not only enhances our understanding of the interactions between tumour and immune cells but also opens new avenues for targeted therapies against exosomal miR-205 in ovarian cancer.
