DNA hypomethylation and ovarian cancer biology.
Hypomethylation of some portions of the genome and hypermethylation of others are very frequent in human cancer. The hypomethylation often involves satellite 2 (Sat2) DNA in the juxtacentromeric (centromere-adjacent) region of chromosome 1. In this study, we analyzed methylation in centromeric and juxtacentromeric satellite DNA in 115 ovarian cancers, 26 non-neoplastic ovarian specimens, and va...
متن کاملNUCL EAR DNA CONTENT AND DNA PLOIDY ANALYSIS IN BREAST CANCER
To investigate the patterns of DNA ploidy and proliferating activity in breast cancer and relate them to other prognostic factors, paraffin blocks of 53 cases of breast carcinoma were studied. Cancer cells obtained by mechanical tissue disaggregation were examined for DNA content, ploidy and S-phase fraction. DNA assay was done using a CAS interactive image analyzing system. All of the cas...

متن کاملDNA hypomethylation and hemimethylation in cancer.
In contrast to earlier views that there was much compartmentalization of the types of sequences subject to cancer-linked changes in DNA epigenetics, it is now clear that both cancer-associated DNA hypomethylation and hypermethylation are found throughout the genome. The hypermethylation includes promoters of tumor suppressor genes whose expression becomes repressed, thereby facilitating cancer ...
متن کاملAnalysis of nuclear DNA content and ploidy in higher plants.
This is the first of a series of units discussing the application of cytometry to plant material. Techniques commonly used for mammalian nuclei evaluation need considerable modification to be successful with plant material. David Galbraith and his colleagues bring together many years of knowledge in plant cytometry. Their unit provides detailed protocols on measuring DNA content, ploidy, and ce...
