Establishment and identification of the human multi-drug-resistant cholangiocarcinoma cell line QBC939/ADM.
Article in Molecular biology reports, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
In this study, we aim to establish the human multi-drug-resistant cholangiocarcinoma cell line QBC939/ADM which can be grow and passaged steadily in 1 μg/ml concentration of adriamycin in appropriate medium. The human multi-drug-resistant cholangiocarcinoma cell line QBC939/ADM was established using the method of exposure to medium with adriamycin alternated between high and low concentration with gradually increasing concentration. Furthermore, QBC939 and QBC939/ADM were both treated with adriamycin, mitomycin and vindesine, and then detected by MTT assay, respectively. Growth cycle and intra-cellular concentrations of ADM within cells of each group were determined by flow cytometry. Expression levels of P-glycoprotein were detected by Western bolt and real-time PCR. Results showed that, compared with QBC939, the inhibitive rates of adriamycin, mitomycin and vindesine to QBC939/ADM were lower. Content of ADM in the QBC939/ADM was lower. Western bolt and real time PCR showed that P-glycoprotein in the QBC939/ADM group was over expressed. Therefore, QBC939/ADM was establish and identified as the multi-drug-resistant cell line, which can grow and be passaged steadily in 1 μg/ml concentration adriamycin in appropriate medium. And the multi-drug-resistant character of QBC939/ADM was indicated to be related to the over expression of P-glycoprotein induced by chemotherapeutic drugs.
