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

Previous studies have demonstrated that the nuclear localization of ras homolog family member A (RhoA), with prominent concentration in the nucleolus, is a common feature in human cancer tissues and cancer cell lines. Although a previous study has demonstrated that the nuclear translocation of RhoA occurs via active transport, a process that occurs through importin α in a nuclear factor-κB-dependent manner, the mechanism, biological function and pathological meaning of the nucleolar residency of RhoA remain to be elucidated. As the cell nucleolus is the site of ribosome biosynthesis, the aim of the present study was to investigate the association between RNA synthesis and the nucleolar localization of RhoA, as well as the molecular mechanisms underlying the residency of RhoA in the nucleolus of HEp-2 (human larynx epithelial carcinoma) cells. Indirect immunofluorescence microscopy was used to evaluate the subcellular distribution of nuclear RhoA, and immunoblotting analysis was used to determine the total cellular protein level of RhoA. Consistent with the results of previous studies, untreated HEp-2 cells exhibited bright nucleolar staining, indicating an increased concentration of RhoA in the nucleoli. Treatment with actinomycin D for the inhibition of RNA synthesis caused a redistribution of RhoA from the nucleoli to the nucleoplasm with a speckled staining pattern. Immunoblotting revealed that neither the total cellular amount of RhoA nor the integrity of RhoA was affected by treatment with actinomycin D. In cells that were treated at a decreased concentration (0.05 mg/l) of actinomycin D, the redistribution of RhoA was reversible following the removal of the drug from the culture medium. However, this reversal was not observed at an increased drug concentration (1 mg/l). Overall, to the best of our knowledge, the results of the present study provide the first
