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

Mitotic progression is regulated by ubiquitin E3 ligase complexes to carefully orchestrate eukaryotic cell division. Here, we show that a relatively new E3 ligase component belonging to the SCF (Skip-Cullin1-F-box protein) E3 ligase family, SCF (FBXL2) , impairs cell proliferation by mediating cyclin D3 polyubiquitination and degradation. Both cyclin D3 and FBXL2 colocalize within the centrosome. FBXL2 overexpression led to G 2/M-phase arrest in transformed epithelia, resulting in the appearance of supernumerary centrosomes, tetraploidy and nuclei where condensed chromosomes are arranged on circular monopolar spindles typical of mitotic arrest. RNAi-mediated knockdown of cyclin D3 recapitulated effects of SCF (FBXL2) expression. SCF (FBXL2) impaired the ability of cyclin D3 to associate with centrosomal assembly proteins [Aurora A, polo-like kinase 4 (Plk4), CDK11]. Thus, these results suggest a role for SCF (FBXL2) in regulating the fidelity of cellular division.
