Effect of teicoplanin on the expression of c-myc and c-fos proto-oncogenes in MCF-7 breast cancer cell line.

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
backgroundTeicoplanin is a member of vancomycin-ristocetin family of glycopeptide antibiotics. It mediated wound healing by increasing neovascularization possibly through activation of MAP kinase signaling pathway. The aim of this study is an evaluation of c-myc and c-fos genes expression after treatment of cells by teicoplanin and determines whether this glycopeptide antibiotic exerts its proliferation effects by influencing the expression of these genes. Hence, this study was designed to elucidate one possible mechanism underlying teicoplanin effects on cell proliferation using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay. MATERIALS AND
methodsBreast cancer cell line, MCF-7, was cultured, and three different concentrations of teicoplanin were added to the plates. We measured the cell proliferation rate by MTT assay. After cell harvesting, total RNA was extracted to synthesize single-stranded cDNA. Real-time polymerase chain reaction was performed, and the data were analyzed.
resultsIt was observed that the level of c-fos and c-myc genes' expressions was decreased at all three different concentrations of teicoplanin.
conclusionit could be concluded that although teicoplanin is considered as an enhancing cell growth and proliferation, but probably its effect is not through MAP kinase signaling pathway or perhaps even has inhibitory effect on the expression of some genes such as c-myc and c-fos in this pathway. Hence, the mechanism of action of teicoplanin for increasing cell propagation, through cell signaling pathways or chromosomal abnormalities, remains unclear, and further studies should be conducted.
