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

The non-receptor tyrosine kinase Fer belongs to a distinct subfamily of F-BAR domain containing kinases implicated in vesicular trafficking and signaling downstream of adhesion and growth factor receptors. Targeted inactivation of the fer gene in a transgenic mouse model of HER2(+), breast cancer was associated with delayed tumor onset and reduced proliferative rates in tumor cells. Fer deficiency was associated with increased rates of epidermal growth factor (EGF)-induced epidermal growth factor receptor (EGFR) internalization and amplified Ras-Raf-Mek-Erk (Ras-MAPK) signaling in primary mammary tumor epithelial cells, as well as increased cytotoxic and anti-proliferative sensitivity to the dual EGFR/HER2 inhibitor Lapatinib (LPN). These observations suggest a model in which accelerated ligand-induced EGFR internalization in Fer-deficient cells hypersensitizes the Ras-MAPK pathway to EGF, resulting in MAPK signal amplification to levels that induce cytostasis, rather than proliferation. Thus, Ras-MAPK cytostatic signaling delays HER2 tumor initiation and increases LPN cytotoxicity in Fer-deficient model systems. Taken together, these data suggest that targeting Fer alone, or in combination with LPN, may be of therapeutic benefit in HER2(+) breast cancer.
