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

purposeCryptotanshinone is a major active component of Salvia miltiorrhiza, which is often used as Chinese herbal medicine in cancer therapy. Here, we systematically assessed the anti-tumor effect of Cryptotanshinone on two melanoma cell lines with low/high-metastatic capacity (B16/B16BL6).

methodsMTT and LDH assays were used to evaluate cell growth and cytotoxicity. We assessed the effect of Cryptotanshinone on cell apoptosis or proliferation by Annexin V, TUNEL or BrdU assay. Cell cycle distribution was detected by flow cytometry. The integrity of cell cycle checkpoints was determined by mutational analyses of B-RAF and N-RAS, and the expression of cell cycle-associated proteins by western blotting.

resultsTreatment with Cryptotanshinone had no obvious effect on cell apoptosis but significantly inhibited cell proliferation. Cryptotanshinone slightly increased the expression of p53, Chk1, and Chk2 in both B16 and B16BL6. Interestingly, Cryptotanshinone induced G1 arrest with a concomitant increase in p21 expression in B16BL6 cells. However, in B16 cells, Cryptotanshinone induced the G2/M arrest through its induction of Cdc25c. Regulation of Cyclin A1, Cyclin B1 and Cdk1/cdc2 expression might contribute to the different cell cycle patterns in B16 and B16BL6 after Cryptotanshinone treatment.

conclusionsCryptotanshinone could have diverse effects on cell cycle events in melanoma cell lines with different metastatic capacity. This property might offer an opportunity to study underlying mechanisms for the different antitumor effects of administered Cryptotanshinone in B16 and B16BL6 cells.
