Induction of apoptosis by the new anticancer drug XK469 in human ovarian cancer cell lines.

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
XK469, a synthetic quinoxaline phenoxypropionic acid derivative, has been found to have selective activity against a broad panel of solid tumors including several drug-resistant cell lines and has been approved for phase I clinical evaluation. Recent studies suggested that XK469 is a selective topoisomerase IIbeta inhibitor, but the mechanism of XK469-induced cell death remains unknown. Here we investigate the ability of XK469 to induce apoptosis of human cancer cells. In the human ovarian cancer cell line PA1, XK469 caused the release of cytochrome c, activation of caspases including caspases 9, 7 and 3, cleavage of PARP, and subsequently cell death. Moreover, Bcl2 and Bax were cleaved in XK469 treated cells. PA1 cells expressing the dominant negative-caspase 9 were less sensitive to XK469. Importantly, in these PA1 cells expressing DN-casp 9, the activation of caspases including caspases 3, 7 and 9, and cleavage of Bax and Bcl2 were inhibited, suggesting that the activation of the mitochondrial pathway is required for XK469-induced anticancer activity. These results indicate that the induction of apoptosis by XK469 may account for its anti-tumor activity and such activity is required for the activation of the mitochondrial pathway. Thus, our study defines a possible mechanism, at least in part, underlying XK469-induced anti-cancer activity.
