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

To prevent aneuploidy, cells require a mitotic surveillance mechanism, the spindle assembly checkpoint (SAC). The SAC prevents metaphase/anaphase transition by blocking the ubiquitylation and destruction of cyclin B and securin via the Cdc20-activated anaphase-promoting complex or cyclosome (APC/C)-mediated proteolysis pathway. This checkpoint involves the kinetochore proteins Mad2, BubR1, and Cdc20. Mad2 and BubR1 are inhibitors of the APC/C, but Cdc20 is an activator. Exactly how the SAC regulates Cdc20 via unattached kinetochores remains unclear; in vertebrates, most current models suggest that kinetochore-bound Mad2 is required for initial binding to Cdc20 to form a stable complex that includes BubR1. Here, we show that the Mad2 kinetochore dimerization recruitment mechanism is conserved and that the recruitment of Cdc20 to kinetochores in Drosophila requires BubR1 but not Mad2. BubR1 and Mad2 can bind to Cdc20 independently, and the interactions are enhanced after cells are arrested at mitosis by the depletion of Cdc27 using RNA interference (RNAi) in S2 cells or by MG132 treatment in syncytial embryos. These findings offer an explanation of why BubR1 is more important than Mad2 for SAC function in flies. These findings could lead to a better understanding of vertebrate SAC mechanisms.
