Abstract:
Knowledge regarding molecular events of cancer development has been rapidly accumulated during the last decade. The discovery of tumor suppressor gene-silencing by aberrant promoter CpG island hypermethylation and histone-directed chromatin remodeling has led epigenetics to its recognition as an important alternative mechanism for carcinogenesis. Epigenetics does not involve changes in nucleotide sequences, but it affects on genetic composition in many ways. Cancer cells integratively co-opt genetic and epigenetic mechanisms to acquire different aspects of carcinogenetic phenotypes. Since epigenetic changes can be reversed with relative ease, the research of cancer epigenetics provides great potential for new therapeutic regimens.
Insights
Epigenetics, involving gene changes without altering DNA sequence, plays a key role in cancer development. Reversible epigenetic modifications offer promising avenues for novel cancer therapies.

Cancer-Critical Genes II: Tumor Suppressor Genes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
