A study of mifepristone/IFN-γ-induced apoptosis of human cholangiocarcinoma cell line FRH-0201 in vitro.

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
objectiveTo investigate the effects of mifepristone, a progesterone receptor (PR) antagonist, through the proliferation of human cholangiocarcinoma cell line FRH-0201 in vitro and the possible mechanisms involved.
methodsA two-step addition of poly-HRP anti-mouse immunoglobulin G detection system was used to detect the expression of PR in FRH-0201 cells. After treatments with various concentrations of mifepristone (10, 20, 40, 80, 160, and 320 μmol/L) at various time intervals (24, 48, and 72 hours), the rate of cell inhibition, the rate of cell apoptosis, and the expression of bax/bcl-2/Fas were analyzed with tetrazolium blue (MTT) assay, flow cytometry, reverse transcription polymerase chain reaction and Western blotting. The effect of mifepristone and mifepristone combined with interferon (IFN)-γ-inducing apoptosis on the cells was observed.
resultsMifepristone remarkably inhibited the proliferation of FRH-0201 cells, which was revealed by MTT assay in a dose- and time-dependent manner. The inhibitory rate gradually increased following the increase of the dosage of mifepristone from a low dosage (10 μmol/L) to a high dosage (320 μmol/L) at different time intervals. Flow cytometry analysis showed mifepristone increased the rate of the FRH-0201 cell-line apoptosis. Notably, the rate of apoptosis increased markedly when the cells were pretreated with IFN-γ and then treated with mifepristone. In addition, mifepristone obviously upregulated bax and Fas expression and downregulated bcl-2 expression.
conclusionMifepristone effectively inhibited the growth of PR-positive human cholangiocarcinoma cell line FRH-0201 in vitro through multiple mechanisms. Mifepristone combined with IFN-γ might therefore induce the apoptosis of the cell line, which is possibly a beneficial clinical scheme for patients suffering from cholangiocarcinoma.
