Common and distinct features of mammary tumors driven by Pten-deletion or activating Pik3ca mutation.
Article in Oncotarget, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
PTEN loss and PIK3CA activation both promote the accumulation of phosphatidylinositol (3, 4, 5)-trisphosphate (PIP3). While these proteins also have distinct biochemical functions, beyond the regulation of PIP3, little is known about the consequences of these differences in vivo. Here, we directly compared cancer signalling in mammary tumors from MMTV-Cre:Ptenf/f and MMTV-Cre:Pik3ca(LSL-H1047R) mice. Using unsupervised hierarchical clustering we found that whereas MMTV-Cre:Pik3ca(LSL-H1047R)-derived tumors fall into two separate groups, designated squamous-likeEx and class14(Ex), MMTV-Cre:Ptenf/f tumors cluster as one group together with PIK3CA(H1047R) class14(Ex), exhibiting a 'luminal' expression profile. Gene Set Enrichment Analysis (GSEA) of Pten(Δ) and PIK3CA(H1047R) class14(Ex) tumors revealed very similar profiles of signalling pathways as well as some interesting differences. Analysis of 18 signalling signatures revealed that PI3K signalling is significantly induced whereas EGFR signalling is significantly reduced in Pten(∆) versus PIK3CA(H1047R) tumors. Thus, Pten(∆) and PIK3CA(H1047R) tumors exhibit discernable differences that may impact tumorigenesis and response to therapy.
