Reliable high-PAP-1-loaded polymeric micelles for cancer therapy: preparation, characterization, and evaluation of anti-tumor efficacy.

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 mitochondrial potassium channel Kv1.3 is a critical therapeutic target, as its blockade induces cancer cell apoptosis, highlighting its therapeutic potential. PAP-1, a potent and selective membrane-permeant Kv1.3 inhibitor, faces solubility challenges affecting its bioavailability and antitumor efficacy. To circumvent these challenges, we developed a tumor-targeting drug delivery system by encapsulating PAP-1 within pH-responsive mPEG-PAE polymeric micelles. These self-assembled micelles exhibited high entrapment efficiency (91.35%) and drug loading level (8.30%). As pH decreased, the micelles exhibited a significant increase in particle size and zeta potential, accompanied by a surge in PAP-1 release. Molecular simulations revealed that PAE's tertiary amine protonation affected the self-assembly process, modifying hydrophobicity and resulting in larger, loosely packed particles. Furthermore, compared to free PAP-1 or PAP-1 combined with MDR inhibitors, PAP-1-loaded micelles significantly enhanced cytotoxicity and apoptosis induction in Jurkat and B16F10 cells, through mechanisms involving decreased mitochondrial membrane potential and elevated caspase-3 activity.
