1 · What the graph read from 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.

2 · The registry

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

purposeA cell-targeted prodrug with good self-assembly properties in aqueous solution was prepared for the anti-cancer drug paclitaxel, offering great potential for further investigation.

methodsWe synthesized hyaluronic acid (HA) with a specific targeting property as a carrier to conjugate with paclitaxel by inserting different amino acids as spacers, including valine, leucine, and phenylalanine, respectively. The structure of HA-amino acid-paclitaxel conjugates was characterized by (1)H NMR and GPC. The loading weight and hydrolysis rate were detected by UV and HPLC, respectively. Their morphology and mean diameter were investigated by SEM and DLS, respectively. The biological activity of HA-amino acid-paclitaxel conjugates was measured by MTT assay and flow cytometry using MCF-7 cells.

resultsThe use of amino acids as spacers between drug and carrier facilitated paclitaxel release from the conjugates. Their morphology demonstrated that the prepared prodrugs could self-assemble to form nanoparticles with a narrow size distribution and spherical shape. Furthermore, the prodrugs exhibited increased cytotoxicity as compared to free drug. Flow cytometry analysis showed that MCF-7 cells treated with conjugates were arrested in the G(2)/M phase of the cell cycle.

conclusionsProdrugs synthesized as HA-amino acid-paclitaxel conjugates exhibited enhanced cytotoxicity in breast cancer cell lines and hence may have potential application as tumor-specific nanoparticulate therapeutic agents.
