Mechanism of Centrosomal Protein 55 (CEP55) Loading Into Exosomes.
Article in Journal of extracellular vesicles, 2025. 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
Up-regulation of Centrosomal Protein 55 (CEP55) in cancer cells increases malignancy, and the protein can be transferred via exosomes. However, the mechanism of how CEP55 is delivered to exosomes is unknown. In this study, we addressed this issue and analysed trafficking of EGFP-CEP55 from early to late endosomes by using high-resolution microscopy. Our data show that endogenous as well as EGFP-CEP55 appeared as dot-like structures in cancer cells. However, we did not find an internalization of CEP55 into early Rab5- and late Rab7-positive endosomes but only into secretory late CD63-positive endosomes. In addition, an association of the CEP55 dots with the endoplasmic reticulum and with ALG-2-interacting protein X (Alix) dots was detected. Moreover, mutation of the CEP55-Alix interaction site strongly reduced the formation of CEP55 dots as well as CEP55 localization in extracellular vesicles. In summary, our data indicate that delivery of CEP55 into exosomes does not occur by the canonical early-to-late endosome pathway but by Alix-mediated recruitment to secretory late secretory CD63 endosomes.
