1 · What the graph read from it

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.

2 · The registry

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

High expression of heat shock proteins (Hsp) in breast cancer has been closely associated with tumor cell proliferation and thus a poor clinical outcome. Quercetin, a good Hsp inhibitor as a dietary flavonoid, possesses anticarcinogenic properties. Although there are many studies on the effects of quercetin on Hsp levels in human breast cancer cells, research on elucidation of its molecular mechanism continues. Herein, we aimed to investigate the effect of quercetin on Hsp levels and whether quercetin is a suitable therapeutic for two breast cancer cell lines (MCF-7 and MDA-MB-231) representing breast tumors which differed in hormone receptor, aggressiveness and treatment responses. To examine the response to high and low doses of quercetin, the cells were treated with three doses of quercetin (10, 25 and 100 μM) determined by MTT. The effects of quercetin on Hsp levels, apoptosis and DNA damage were examined by western blot analysis, caspase activity assay, comet assay and microscopy in human breast cancer cells. Compared to MDA-MB231 cells, MCF-7 cells were more affected by quercetin treatments. Quercetin effectively suppressed the expression of Hsp27, Hsp70 and Hsp90. While quercetin did not induce DNA damage, it triggered apoptosis at high levels. Although an increase in NF-κB levels is observed in the cells exposed to quercetin, the net result is the anticancer effect in case of Hsp depletion and apoptosis induction. Taken together our findings suggested that quercetin can be an effective therapeutic agent for breast cancer therapy regardless of the presence or absence of hormone receptors.
