Epigenetically mediated gene silencing a companion to genetic alterations in driving tumorigenesis /

Table of Contents: “…Contents: Introduction to epigenetic changes in cancer -- defining the process of promoter DNA hypermethylation as a constituent of a broad range of chromatin abnormalities in cancer -- defining the genes aberrantly silenced in cancer including approaches being used to screen the cancer genome for such genes -- defining what is known about the interaction of DNA methylation and chromatin modifications for initiating and maintaining gene silencing in cancer -- outlining the position of aberrant gene silencing in tumor progression and particularly highlighting the key role these changes may play for the earliest steps in tumorigenesis -- defining the potential for using DNA hypermethylated gene promoter sequences as molecular markers for cancer risk assessment, early diagnosis and prognosis -- discussing the possibilities for targeting reversal of gene silencing as a prevention and therapeutic strategy for cancer.…”
