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

Long-term sorafenib treatment triggers resistance to chemotherapy in patients with hepatocellular carcinoma (HCC). In order to investigate the mechanisms of sorafenib resistance in HCC, the aim of the present study was to develop a resistant human liver cell line via long-term exposure to sorafenib. The cytotoxicity cell counting kit-8 assay was used to evaluate drug sensitivity. Reverse transcription-quantitative polymerase chain reaction and western blotting were used to examine the molecular mechanisms underpinning sorafenib resistance. Migratory and invasive properties in resistant cells were assessed using Transwell assays. The results from the present study revealed that resistant cells became insensitive to sorafenib treatment and exhibited increased migratory and invasive capacities. Activation of the phosphatidylinositol-3-kinase (PI3K)/Akt signaling pathway and epithelial-mesenchymal transition was characteristic of resistant cells. The use of LY294002, a PI3K inhibitor, was able to suppress the activation of Akt and extracellular signal-regulated kinase 1/2, attenuated the migratory and invasive capacities of resistant cells. Data from the present study indicates that inhibition of the PI3K signaling pathway with LY294002 exerts suppressive effects on sorafenib resistance and provides an attractive novel therapeutic regime in patients with advanced HCC.
