Cancerous inhibitor of protein phosphatase 2A promotes premature chromosome segregation and aneuploidy in prostate cancer cells through association with shugoshin.

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.
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
Yeast two-hybrid (Y2H) studies have shown that cancerous Inhibitor of protein phosphatase 2A (CIP2A) interacted with several proteins, including leucine-rich repeat-containing protein 59 (LRRC59), suggesting that CIP2A may interact with the chromosome maintenance protein, shugoshin (Sgol1). We previously showed that LRRC59 interacted with CIP2A, which was required for CIP2A nuclear localization. Thus, we predicted that CIP2A and Sgol1 may also interact. Sgol1 is a nuclear protein that regulates chromosome segregation during cell division via protection of cohesin ring proteins. Here, we demonstrated that Sgol1 and the C-terminus of CIP2A interact in prostate carcinoma cell lines in a protein phosphatase 2A (PP2A)-dependent manner. Moreover, we demonstrated that depletion of CIP2A in PC-3 cells decreases premature chromosome segregation, whereas overexpression of CIP2A in an immortalized prostate cell line increases premature chromosome segregation. Importantly, we further showed that CIP2A depletion decreases the incidence of aneuploidy and stabilizes cohesin complex proteins, while overexpression of CIP2A destabilizes Sgol1. Thus, our findings strongly suggest that CIP2A promotes cell cycle progression, premature chromosome segregation, and aneuploidy, possibly through a novel interaction with Sgol1.
