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

Kaempferol (KF), a flavonoid compound isolated from herbal medicines, has been reported to play a significant role in inhibiting certain types of cancer. Although recent studies reported that KF exerted inhibitive activity on liver cancer, they failed to elucidate the signaling pathways and synergistic effects in combination with chemotherapeutic drugs currently in use in the clinical setting. In the present study, the signaling pathways and synergistic effects of KF in liver cancer cells were investigated. Nine liver cancer cell lines were used to assess the inhibitive activity and synergistic effects of KF. Cellular behavioral experiments, such as viability, colony formation, cell cycle arrest, apoptotic, wound healing, and Transwell assays were used to assess the effects of KF on the proliferation, apoptosis, migration, and invasion of liver cancer cells. Western blotting was performed to validate the key signaling pathway elements underlying those cellular behaviors. KF exhibited inhibitory effects on nine liver cancer cell lines in time‑ and dose‑dependent manners and was mostly nontoxic to the normal hepatocyte cells. The combination of KF and doxorubicin revealed a stronger inhibitive effect on the viability of liver cancer cells. Combination therapy also revealed higher suppressive effects on colony formation, cell cycle progression, survival, DNA damage response, and mitochondrial function. By western blotting assay, mitochondrial and caspase signaling pathways were determined to be involved in proliferation inhibition. In wound healing and Transwell invasion assays, combination therapy also exhibited more robust inhibitory activity in blocking the migration and invasion of liver cancer cells. PI3K/mTOR/MMP protein pathways were also revealed to be related to cell migration inhibition. KF alone exhibited an inhibitory effect on proliferation, migration, and invasion of liver cancer cells, and its synergistic effects revealed stronger inhibitory activities. The present data indicated that KF is a promising candidate as a complementary medicine to conventional chemotherapeutic drugs.
