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

Betulin (lup-20(29)-ene-3β, 28-diol) is an abundant, naturally occurring triterpene. It is commonly isolated from the bark of birch trees and forms up to 30% of the dry weight of the extractive. In the present study, we revealed its antiproliferative effects and mechanisms using two lung carcinoma cells (A549 and NCI-292). By 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and bromodeoxyuridine (BrdU) incorporation assays, we found that betulin could efficiently inhibit cell growth and proliferation. Besides, several key genes of cell-cycle regulators were also affected by betulin treatment. At the molecular level, our results demonstrated that treatment with betulin was also associated with activation of AMP kinase and inhibition of mTOR/p70S6K/pS6 signaling in these cells. In agreement, inhibition of AMPK signaling largely reversed the antiproliferative roles of betulin. Taken together, these data provide evidence for a mechanism that may contribute to the antineoplastic effects of betulin and justify further work to explore its potential roles in lung cancer prevention and treatment.
