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

Cooperative communications between the central spindle and the contractile ring are critical for the spatial and temporal regulation of cytokinesis. Here we report that MyoGEF, a guanine nucleotide exchange factor that localizes to the central spindle and cleavage furrow, interacts with centrosome/spindle pole-associated protein (CSPP), which is concentrated at the spindle pole and central spindle during mitosis and cytokinesis. Both in vitro and in vivo pulldown assays show that MyoGEF interacts with CSPP. The C-terminus of MyoGEF and N-terminus of CSPP are required for their interaction. Immunofluorescence analysis indicates that MyoGEF and CSPP colocalize at the central spindle. Depletion of CSPP or MyoGEF by RNA-interference (RNAi) not only causes defects in mitosis and cytokinesis, such as metaphase arrest and furrow regression, but also mislocalization of nonmuscle myosin II with a phosphorylated myosin regulatory light chain (p-MRLC). Importantly, CSPP depletion by RNAi interferes with MyoGEF localization at the central spindle. Finally, MyoGEF interacts with ECT2, and RNAi-mediated depletion of MyoGEF leads to mislocalization of ECT2 and RhoA during cytokinesis. Therefore, we propose that CSPP interacts with and recruits MyoGEF to the central spindle, where MyoGEF contributes to the spatiotemporal regulation of cytokinesis.
