Change in Expression of Survivin Caused by Using Oxaliplatin in HCT116 Colon Cancer Cells.
Article in Journal of the Korean Society of Coloproctology, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
purposeOxaliplatin is a third-generation platinum compound, and it has no nephrotoxicity and has reduced bone marrow toxicity. Cancer cells that are resistant to cisplatin are sensitive to oxaliplatin. Oxaliplatin is used widely for the treatment of colon cancers. Recently, oxaliplatin was reported to inhibit the expression of survivin, which protects cell apoptosis. However, there are no reports on the expressions of survivin variants and the changes in intracellular localization of survivin in cancer cells. We studied the expression of survivin caused by oxaliplatin in HCT116 colon cancer cells, and we observed the localization of survivin in the mitotic phase.
methodsWe treated the HCT116 colon cancer cells with 2.0 µM of oxaliplatin, and we studied the expressions of survivin protein, and survivin mRNA variants, as well as the changes in intracellular localization, by using the Western blot method, RT-PCR, immunocytochemistry, and flowcytometry.
resultsOxaliplatin inhibits the expression of the survivin protein and survivin mRNA in HCT116 colon cancer cells. The expression of the survivin-2B variants, which have no antiapoptotic activity but control cell mitosis by localization on a microtubule, is reduced continuously 2 days after treatment with oxaliplatin. In immunocytochemistry, expression of survivin in the cytoplasm is reduced and especially is not expressed in microtubules and contractile rings.
conclusionOne of the mechanisms of oxaliplatin is to inhibit the expression of and to change the localization of survivin. Based on these results, we suggest that changes in the expression of survivin variants and in their localization are two effects of oxaliplatin.
