Injectable (-)-gossypol-loaded Pluronic P85 micelles for cancer chemoradiotherapy.
Article in International journal of radiation biology, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
purposeThe aim of tumor-specific chemoradiotherapy is to achieve synergistic anticancer effects with clinically acceptable toxicity. Our previous studies showed that Pluronic P85 augments radiation cancer cell killing of (±)-gossypol in vitro. In this study, the radiosensitizing effect of (-)-gossypol, more potent Bcl protein inhibitor, with Pluronic P85 was investigated. MATERIALS AND
methodsThe inhibitory effect of (-)-gossypol solubilized Pluronic P85 with 0-8 Gy of radiation on clonogenic survival rate of A549 human lung adenocarcinoma cells was investigated in vitro. The anticancer effect of (-)-gossypol-solubilized Pluronic P85 with fractionated radiation of 15 Gy was assessed by A549 tumor-bearing mice.
results(-)-Gossypol-loaded Pluronic P85 was found to be a more potent radiosensitizer in vitro. Pluronic P85 increased the anti-proliferative activity of (-)-gossypol against A549 cells (82 ± 42 versus 190 ± 60 nM). In addition, the combination of P85 and (-)-gossypol effectively reduced clonogenic survival of A549 cells: (11 ± 5%) compared to (-)-gossypol and P85 alone (62 ± 27% and 93 ± 13%, respectively), and enhanced radiation cancer cell killing. In vivo, P85 (200 mg/kg/day) and (-)-gossypol (15 mg/kg/day) could be safely injected intravenously over 5 days and enhanced radiation-related tumor control in an A549 xenograft model.
conclusionPluronic P85 and (-)-gossypol act as a novel dual agent radiosensitizer and holds promise as a chemoradiotherapeutic strategy.
