DNA Methylation, Nuclear Organization, and Cancer
The dramatic re-organization of the cancer cell nucleus creates telltale morphological features critical for pathological staging of tumors. In addition, the changes to the mutational and epigenetic landscape in cancer cells alter the structure and stability of the genome and directly contribute to malignancy. DNA methylation is one of the best studied epigenetic changes in cancer, as nearly ev...
متن کاملDNA methylation, nuclear structure, gene expression and cancer.
DNA methylation, chromatin structure, transcription, and cancer have traditionally been studied as separate phenomena. Recent data provide now direct physical and functional links between these processes revealing a complex network of interactions and mutual dependences. Methylated DNA is bound by methyl-CpG binding protein (MeCP) complexes that include histone deacetylases (HDACs). This recrui...
متن کاملDNA methylation and cancer.
DNA methylation is an important regulator of gene transcription, and its role in carcinogenesis has been a topic of considerable interest in the last few years. Alterations in DNA methylation are common in a variety of tumors as well as in development. Of all epigenetic modifications, hypermethylation, which represses transcription of the promoter regions of tumor suppressor genes leading to ge...
متن کاملDNA methylation affects nuclear organization, histone modifications, and linker histone binding but not chromatin compaction
DNA methylation has been implicated in chromatin condensation and nuclear organization, especially at sites of constitutive heterochromatin. How this is mediated has not been clear. In this study, using mutant mouse embryonic stem cells completely lacking in DNA methylation, we show that DNA methylation affects nuclear organization and nucleosome structure but not chromatin compaction. In the a...
متن کاملAlcohol, DNA Methylation, and Cancer
Cancer is one of the most significant diseases associated with chronic alcohol consumption, and chronic drinking is a strong risk factor for cancer, particularly of the upper aerodigestive tract, liver, colorectum, and breast. Several factors contribute to alcohol-induced cancer development (i.e., carcinogenesis), including the actions of acetaldehyde, the first and primary metabolite of ethano...
