The Mcs7 quantitative trait locus is associated with an increased susceptibility to mammary cancer in congenic rats and an allele-specific imbalance.
Article in Oncogene, 2006. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Identification of high-penetrance breast cancer genes such as Brca1 has been accomplished by analysing familial cases. However, these genes occur at low frequency and do not account for the majority of genetic risk. Identification of low-penetrance alleles that occur commonly in populations may benefit from unbiased genome-wide screening. One such approach uses linkage studies in rodent models to identify homologous human candidates. The Wistar Kyoto (WKy) rat is resistant to mammary carcinomas induced with 7,12-dimethybenz[a]anthracene (DMBA), whereas the Wistar Furth (WF) strain is susceptible. Previous genome-wide linkage studies in crosses of these strains identified three WKy resistance quantitative trait loci, Mcs5, Mcs6 and Mcs8, and one predicted to increase susceptibility, Mcs7. The Mcs7 region on rat chromosome 10 (RNO10) is orthologous to human 17q, a common site of genetic aberrations in breast cancer. Here, we establish the independent phenotype conferred by Mcs7 using congenic rats carrying the WKy Mcs7 locus on a WF background. Tumor multiplicity was significantly higher ( approximately 50%) in DMBA-treated congenics homozygous and heterozygous for the WKy allele at the Mcs7 locus, compared to controls. We also investigated allelic imbalance (AI) in mammary carcinomas from (WKy x WF)F1 rats and Mcs7 heterozygous congenics. Of the four known WKy Mcs loci tested, only Mcs7 displayed AI. The pattern of AI in carcinomas from both F1 and Mcs7 congenic rats was similar, suggesting a WF allelic loss. Together, these data suggest that one or more breast cancer-related genes are located within the dominantly acting WKy allele at the Mcs7 locus.
