PTPROt-mediated regulation of p53/Foxm1 suppresses leukemic phenotype in a CLL mouse model.
Article in Leukemia, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers.
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
The gene encoding PTPROt (truncated isoform of protein tyrosine phosphatase receptor-type O) is methylated and suppressed in chronic lymphocytic leukemia (CLL). PTPROt exhibits in vitro tumor-suppressor characteristics through the regulation of B-cell receptor (BCR) signaling. Here we generated transgenic (Tg) mice with B-cell-specific expression of PTPROt. Although lymphocyte development is normal in these mice, crossing them with TCL1 Tg mouse model of CLL results in a survival advantage compared with the TCL1 Tg mice. Gene expression profiling of splenic B-lymphocytes before detectable signs of CLL followed by Ingenuity Pathway Analysis revealed that the most prominently regulated functions in TCL1 Tg vs non-transgenic (NTg) and TCL1 Tg vs PTPROt/TCL1 double Tg are the same and also biologically relevant to this study. Further, enhanced expression of the chemokine Ccl3, the oncogenic transcription factor Foxm1 and its targets in TCL1 Tg mice were significantly suppressed in the double Tg mice, suggesting a protective function of PTPROt against leukemogenesis. This study also showed that PTPROt-mediated regulation of Foxm1 involves activation of p53, a transcriptional repressor of Foxm1, which is facilitated through suppression of BCR signaling. These results establish the in vivo tumor-suppressive function of PTPROt and identify p53/Foxm1 axis as a key downstream effect of PTPROt-mediated suppression of BCR signaling.
