Effects of Cholesterol on the Breast Cancer Resistance Protein: Studies through the Synthesis and Biological Evaluation of Chemical Tools.
Article in ChemMedChem, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
The breast cancer resistance protein (BCRP/ABCG2) plays a major role in the multidrug resistance of cancers toward chemotherapeutic treatments. It was demonstrated that cholesterol regulates the ABCG2 activity, suggesting that lower levels of membrane cholesterol decrease the ABCG2 activity in mammalian cells. However, the precise mechanism remains unclear. To better understand the role of cholesterol in the ABCG2 activity, we studied the ABCG2-mediated efflux of different substrates in the presence of different concentrations of cholesterol. Moreover, we synthetized derivatives of cholesterol linked either to known ABCG2 inhibitors or fluorescents probes. A chalcone-cholesterol was synthetized to investigate the influence of cholesterol on ABCG2 inhibition, and a BODIPY-cholesterol was developed to track cholesterol trafficking on mammalian cells and investigate the behavior of cholesterol as an ABCG2 substrate. The obtained results with three different substrates of ABCG2 showed that cholesterol did not affect the intracellular amount of substrates nor the transport activity.
