Antitumor Activity of Taxol Engross Taxol-Caveolin-1 Interaction via Lipid Raft Structure-"Caveolae".

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
Taxol is one of the most widely used natural antitumor drugs that have shown considerable success in treating cancers of different lineage. However, the development of resistance to taxol is still a significant issue. Caveolae, the cave-like structures found on the surface of many cancerous cells, are enriched in cholesterol and are known to play a pivotal role in drug uptake. Caveolin-1 (Cav-1), the principal structural proteins of the caveolae, interacts with signaling molecules through a scaffolding domain. In the present study, we observed that Cav-1-GFP clusters were instantly recruited to the cell membrane. Interestingly, Caveolae formation followed by internalization was observed after the treatment with time. The recruitment and the formation of the Cav-1-GFP clusters are provided in supplementary video 2 (SV2). The results obtained from molecular docking indicate favorable taxol-Cav-1 interaction. To further confirm the influence of Cav-1 proteins in the uptake and effects of taxol, the cells were treated with beta-cyclodextrin (β-CD), cholesterol, and taxol combinations. The result suggests that the depletion of cholesterol in HeLa cells makes them less susceptible to taxol at a lower concentration. These observations provide evidence of the interaction between Cav-1 and taxol. Further studies that may elucidate the molecular mechanism of uptake of taxol through caveolae/Cav-1 will help to determine if Cav-1 can be used to increase the uptake of taxol by cancer cells and sensitize the drug-resistant cancer cells to taxol.
