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

Autophagy is a catabolic process for degradation of intracellular components and plays an important role in the development and growth of cancer. Our preliminary screening confirmed that an extract from the root of Saussurea lappa remarkably suppressed the proliferation of HepG2 hepatocellular carcinoma cells and inhibited autophagy. In this study, we explored the effects of costunolide (CL) and dehydrocostuslactone (DCL), which are bioactive sesquiterpene lactones in this extract, on autophagy modulation in HepG2 cells. An analysis of autophagy-related proteins demonstrated that CL and DCL blocks the autophagy process that leads to the accumulation of microtubule-associated protein 1 light chain 3 (LC3) and SQSTM1/p62 (p62). LC3 turnover assays indicated that CL and DCL trigger autophagy inhibition by blocking the autophagic flux, thereby resulting in the accumulation of LC3-II and p62. These results are encouraging and warrant further study of CL and DCL for potential use as autophagy inhibiting agents for liver cancer therapy.
