The function of Cav-1 in MDA-MB-231 breast cancer cell migration and invasion induced by ectopic ATP5B.
Article in Medical oncology (Northwood, London, England), 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It has been retracted, and should not be counted. Cited by 5 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
Ectopic ATP5B, which is located in a unique type of lipid raft caveolar structure, can be upregulated by cholesterol loading. As the structural component of caveolae, Cav-1 is a molecular hub that is involved in transmembrane signaling. In a previous study, the ATP5B-specific binding peptide B04 was shown to inhibit the migration and invasion of prostate cancer cells, and the expression of ATP5B on the plasma membrane of MDA-MB-231 cells was confirmed. The present study investigated the effect of ectopic ATP5B on the migration and invasion of MDA-MB-231 cells and examined the involvement of Cav-1. Cholesterol loading increased the level of ectopic ATP5B and promoted cell migration and invasion. These effects were blocked by B04. Ectopic ATP5B was physically colocalized with Cav-1, as demonstrated by double immunofluorescence staining and coimmunoprecipitation. After Cav-1 knockdown, the migration and invasion abilities of MDA-MB-231 cells were significantly decreased, suggesting that Cav-1 influences the function of ectopic ATP5B. Furthermore, these effects were not reversed after treatment with cholesterol. We concluded that Cav-1 may participate in MDA-MB-231 cell migration and invasion induced by binding to ectopic ATP5B.
