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

objectivesPIWIL2 is widely expressed in various tumours and implicated in playing a role in tumourigenesis. For a more thorough study of PIWIL2 functions in tumour cells, we aimed to establish PIWIL2-specific transcript knock-down/knockout HepG2 cell lines using transcription activator-like effector nuclease (TALEN) technology. Furthermore, we proposed to use the cell models to explore PIWIL2 functions in TGF-β signalling in HepG2 cells. HepG2s are human hepatocellular carcinoma cells. MATERIALS AND

methodsWe established PIWIL2 knock-down or knock-out cell lines in HepG2 using TALEN technology. Next, we sought to use the cell line models to investigate effects of full length PIWIL2-specific transcripts in cell proliferation induced by TGF-β.

resultsFirst, we established PIWIL2-specific transcript mono-allele and bi-allele knockout HepG2 cell lines. By using the cell line models, we found that specific transcript knockdown of full length PIWIL2 can suppress cell proliferation, while ectopic expression of PIWIL2 enhanced proliferation of HepG2 by suppressing the TGF-β pathway. Furthermore, we demonstrated that PIWIL2 can interact with HSP90 to prevent formation of HSP90-TβR complexes, which promote degradation of TβRs.

conclusionsTaken together, our study revealed critical negative regulation of TGF-β signalling by PIWIL2 in HepG2 tumour cells, and provided an effective strategy to study specific gene transcript functions in cells.
