Cellular distribution studies of the nitric oxide-generating antineoplastic prodrug O(2) -(2,4-dinitrophenyl)1-((4-ethoxycarbonyl)piperazin-1-yl)diazen-1-ium-1,2-diolate formulated in Pluronic P123 micelles.

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
objectiveNitric oxide (NO) possesses antitumour activity. It induces differentiation and apoptosis in acute myeloid leukaemia (AML) cells. The NO prodrug O(2) -(2,4-dinitrophenyl)1-((4-ethoxycarbonyl)piperazin-1-yl)diazen-1-ium-1,2-diolate, or JS-K, has potent antileukaemic activity. JS-K is also active in vitro and in vivo against multiple myeloma, prostate cancer, non-small-cell lung cancer, glioma and liver cancer. Using the Pluronic P123 polymer, we have developed a micelle formulation for JS-K to increase its solubility and stability. The goal of the current study was to investigate the cellular distribution of JS-K in AML cells.
methodsWe investigated the intracellular distribution of JS-K (free drug) and JS-K formulated in P123 micelles (P123/JS-K) using HL-60 AML cells. We also studied the S-glutathionylating effects of JS-K on proteins in the cytoplasmic and nuclear cellular fractions. KEY
findingsBoth free JS-K and P123/JS-K accumulate primarily in the nucleus. Both free JS-K and P123/JS-K induced S-glutathionylation of nuclear proteins, although the effect produced was more pronounced with P123/JS-K. Minimal S-glutathionylation of cytoplasmic proteins was observed.
conclusionsWe conclude that a micelle formulation of JS-K increases its accumulation in the nucleus. Post-translational protein modification through S-glutathionylation may contribute to JS-K's antileukaemic properties.
