Epigenome-wide association study reveals decreased average methylation levels years before breast cancer diagnosis [PDF]
Interest in the potential of DNA methylation in peripheral blood as a biomarker of cancer risk is increasing. We aimed to assess whether epigenome-wide DNA methylation measured in peripheral blood samples obtained before onset of the disease is ...

Chromosome-specific DNA Repeat Probes [PDF]
In research as well as in clinical applications, fluorescence in situ hybridization (FISH) has gained increasing popularity as a highly sensitive technique to study cytogenetic changes. Today, hundreds of commercially available DNA probes serve the basic needs of the biomedical research community. Widespread applications, however, are often limited by

Changes in the subgingival biofilm composition after coronally positioned flap
OBJECTIVES: This study evaluated the effects of coronally positioned flap (CPF) on the subgingival biofilm composition. MATERIAL AND METHODS: Twenty-two subjects with gingival recessions were treated with CPF. Clinical parameters were assessed before and

Novel deletions causing pseudoxanthoma elasticum underscore the genomic instability of the ABCC6 region [PDF]
Mutations in ABCC6 cause pseudoxanthoma elasticum (PXE), a heritable disease that affects elastic fibers. Thus far, >200 mutations have been characterized by various PCR-based techniques (primarily direct sequencing), identifying up to 90% of PXE-causing

Probing Rad51-DNA interactions by changing DNA twist [PDF]
In eukaryotes, Rad51 protein is responsible for the recombinational repair of double-strand DNA breaks. Rad51 monomers cooperatively assemble on exonuclease-processed broken ends forming helical nucleo-protein filaments that can pair with homologous regions of sister chromatids.
