The Non-coding Mammary Carcinoma Susceptibility Locus, Mcs5c, Regulates Pappa Expression via Age-Specific Chromatin Folding and Allele-Dependent DNA Methylation
In understanding the etiology of breast cancer, the contributions of both genetic and environmental risk factors are further complicated by the impact of breast developmental stage. Specifically, the time period ranging from childhood to young adulthood represents a critical developmental window in a woman's life when she is more susceptible to environmental hazards that may affect future breas...
متن کاملMcs5c: a mammary carcinoma susceptibility locus located in a gene desert that associates with tenascin C expression.
Genetic factors have been estimated to account for at least 30% of a woman's risk to develop breast cancer. We have developed a rat model using Wistar Furth (WF) and Wistar Kyoto (WKy) strains to genetically identify mammary cancer susceptibility loci. The WKy allele of the mammary carcinogenesis susceptibility locus Mcs5c, was previously shown to reduce carcinoma multiplicity after 7,12-dimeth...
متن کاملDNA damage and Repair Modify DNA methylation and Chromatin Domain of the Targeted Locus: Mechanism of allele methylation polymorphism
We characterize the changes in chromatin structure, DNA methylation and transcription during and after homologous DNA repair (HR). We find that HR modifies the DNA methylation pattern of the repaired segment. HR also alters local histone H3 methylation as well chromatin structure by inducing DNA-chromatin loops connecting the 5' and 3' ends of the repaired gene. During a two-week period after r...
متن کاملAllele-specific non-CG DNA methylation marks domains of active chromatin in female mouse brain.
DNA methylation at gene promoters in a CG context is associated with transcriptional repression, including at genes silenced on the inactive X chromosome in females. Non-CG methylation (mCH) is a distinct feature of the neuronal epigenome that is differentially distributed between males and females on the X chromosome. However, little is known about differences in mCH on the active (Xa) and ina...
متن کاملAllele-Specific, Age-Dependent and BMI-Associated DNA Methylation of Human MCHR1
BACKGROUND Melanin-concentrating hormone receptor 1 (MCHR1) plays a significant role in regulation of energy balance, food intake, physical activity and body weight in humans and rodents. Several association studies for human obesity showed contrary results concerning the SNPs rs133072 (G/A) and rs133073 (T/C), which localize to the first exon of MCHR1. The variations constitute two main haplot...
