Transgenic overexpression of IGF-IR disrupts mammary ductal morphogenesis and induces tumor formation.
Article in Oncogene, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 86 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
Overexpression and hyperactivation of the type I insulin-like growth factor receptor (IGF-IR) has been observed in human breast tumor biopsies. In addition, in vitro studies indicate that overexpression of IGF-IR is sufficient to transform cells such as mouse embryo fibroblasts and this receptor promotes proliferation and survival in breast cancer cell lines. To fully understand the function of the IGF-IR in tumor initiation and progression, transgenic mice containing human IGF-IR under a doxycycline-inducible MMTV promoter system were generated. Administration of 2 mg/ml doxycycline in the animals' water supply beginning at 21 days of age resulted in elevated levels of IGF-IR in mammary epithelial cells as detected by Western blotting and immunohistochemistry. Whole mount analysis of 55-day-old mouse mammary glands revealed that IGF-IR overexpression significantly impaired ductal elongation. Moreover, histological analyses revealed multiple hyperplasic lesions in the mammary glands of these 55-day-old mice. The formation of palpable mammary tumors was evident at approximately 2 months of age and was associated with increased levels of IGF-IR signaling molecules including phosphorylated Akt, Erk1/Erk2 and STAT3. Therefore, these transgenic mice provide evidence that IGF-IR overexpression is sufficient to induce mammary epithelial hyperplasia and tumor formation in vivo and provide a model to further understand the function of IGF-IR in mammary epithelial transformation.
