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

Cancer stem cells (CSCs) play a critical role in both cancer initiation and relapse as they are resistant to most cytotoxic agents and able to proliferate indefinitely. The plant alkaloid oxymatrine has many biological activities including the ability to induce cell cycle arrest and apoptosis, which makes it a potentially useful agent for targeting cancer cells. In order to determine whether it has beneficial pharmacological properties to eradicate CSCs, we analyzed the effects of oxymatrine on MCF-7 breast cancer cells. Cancer stem-like cells' (side population, SP) identification and sorting were performed. The inhibitory effect of oxymatrine was evaluated on the sorted SP and non-SP cells. The results indicated that oxymatrine caused a dose-dependent reduction in the proliferation of MCF-7 cells and a decrease in SP cells. Wnt/β-catenin signaling pathway was also examined by analyzing the expression of total β-catenin and phosphorylated β-catenin in cytoplasm, and the results showed that the growth inhibitory effects of oxymatrine treatment on MCF-7 cells may be due to the inhibition of SP and Wnt/β-catenin signaling pathway. Further work is warranted to explore whether oxymatrine may be a useful novel therapeutic drug for targeting breast CSCs.
