Gene Section RASSF1 (Ras association (RalGDS/AF-6) domain family member 1)

... The mechanism of inactivation of this tumor suppressor consists in promoter hypermethylation. The gene promoter was found hypermetylated in 90 % of primary kidney tumors and 40 % of lung tumors. Hypermethylation and loss of transcription were causally related. Hypermethylation occurs in variable per ...

... For such a difficult question to be answered, a basic understanding of cancer is needed. Certain genes regulate cell growth and division, and if one of these genes is mutated, the cell will not be able to regulate its growth and division, leading to cancer. A gene mutation may be spontaneous, or ca ...

Polycomb Group Proteins and Cancer

The Polycomb-group proteins (PcGs) are a family of proteins that use epigenetic mechanisms to maintain or repress expression of their target genes. They were originally discovered in Drosophila (fruit flies), though they've been shown to be conserved in many species due to their vital roles in embryonic development. These proteins' ability to alter gene expression has made them targets of investigation for research groups seeking to understand disease pathology and oncology.
