Genetic control of ductal morphology, estrogen-induced ductal growth, and gene expression in female mouse mammary gland.
Article in Endocrinology, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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 uterotropic response of the uterus to 17β-estradiol (E2) is genetically controlled, with marked variation observed depending on the mouse strain studied. Previous genetic studies from our laboratory using inbred mice that are high (C57BL6/J; B6) or low (C3H/HeJ; C3H) responders to E2 led to the identification of quantitative trait loci (QTL) associated with phenotypic variation in uterine growth and leukocyte infiltration. Like the uterus, phenotypic variation in the responsiveness of the mammary gland to E2 during both normal and pathologic conditions has been reported. In the current experiment, we utilized an E2-specific model of mammary ductal growth combined with a microarray approach to determine the degree to which genotype influences the responsiveness of the mammary gland to E2, including the associated transcriptional programs, in B6 and C3H mice. Our results reveal that E2-induced mammary ductal growth and ductal morphology are genetically controlled. In addition, we observed a paradoxical effect of mammary ductal growth in response to E2 compared with what has been reported for the uterus; B6 is a high responder for the uterus and was a low responder for mammary ductal growth, whereas the reverse was observed for C3H. In contrast, B6 was a high responder for mammary ductal side branching. The B6 phenotype was associated with increased mammary epithelial cell proliferation and apoptosis, and a distinct E2-induced transcriptional program. These findings lay the groundwork for future experiments designed to investigate the genes and mechanisms underlying phenotypic variation in tissue-specific sensitivity to systemic and environmental estrogens during various physiological and disease states.
