Extracellular Vesicles Released From Prostate Cancer Cells Confer Pro-Tumor Properties to Adipocytes by Stimulating Lipolysis.
Article in BioFactors (Oxford, England). The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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
There is consistent evidence of an association between obesity and the risk of prostate cancer (PCa). A crosstalk between PCa and adipocytes has been highlighted; however, the role of extracellular vesicles (EVs) in this communication still needs to be elucidated. Herein, we demonstrated that PCa EVs can trigger lipolysis in 3T3-L1 adipose cells, by downregulating G0/G1 switch protein 2 (G0S2), inducing adipose triglyceride lipase (ATGL) expression and activating the cyclic AMP (cAMP)/protein kinase A (PKA)/hormone-sensitive lipase (HSL) signaling pathway. Interestingly, we showed that the free fatty acids (FFAs) released from the EV-treated adipocytes could increase PCa cell proliferation and clonogenic ability. Moreover, they promoted tumor cell migration and invasion, while parallelly reducing the induction of anoikis. Mechanistically, FFAs were found to trigger Akt activation, and pharmacological inhibition of this protein by BEZ235 could successfully counteract their cancer-promoting effects. Collectively, these results support the presence of an EV-driven bidirectional interplay between PCa cells and adipocytes, which reprograms the latter toward a lipolytic, tumor-promoting phenotype.
