Pluronic P123 modified nano micelles loaded with doxorubicin enhanced tumor-suppressing effect on drug-resistant breast cancer cells.
Article in Aging, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers, 1 of them a synthesis that pooled it.
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
objectiveNano micelles (NMs) have been widely used for various biomedical applications due to its unique physiochemical properties. This study aimed to investigated the anti-tumor effect of doxorubicin (Dox)-loaded Pluronic P123 (P123) and PEG2000-DSPE mixed NMs in drug-resistant breast cancer cells.
resultsThe expression of P-gp and MDR1 gene was highly expressed in MCF-7R but not MCF-7 cells. The cellular uptake of P123-PEG2000-DSPE (Dox) was higher than that of free Dox and PEG2000-DSPE (Dox) in MCF-7R cells. Furthermore, compared with free Dox, both PEG2000-DSPE (Dox) and P123-PEG2000-DSPE (Dox) significantly diminished cell viability, and promoted cell apoptosis in MCF-7R cells. In addition, the P123-modified NMs obviously inhibited the expression of P-gp and MDR1.
conclusionsP123-PEG2000-DSPE (Dox) had a superior anti-tumor activity than PEG2000-DSPE (Dox) in MCF-7R cells through P-gp-mediated drug excretion and drug resistance mechanisms.
methodsThe PEG2000-DSPE NMs (PEG2000-DSPE), P123 and PEG2000-DSPE mixed NMs (P123-PEG2000-DSPE), Dox-loaded PEG2000-DSPE NMs (PEG2000-DSPE (Dox)), and Dox-loaded Pluronic P123 and PEG2000-DSPE mixed NMs (P123-PEG2000-DSPE (Dox)) were prepared, and then the morphologies and the size distribution of PEG2000-DSPE (Dox) and P123-PEG2000-DSPE (Dox) were observed by transmission electron microscopy (TEM) and dynamic light scattering (DLS), respectively.
